[Effects of the Invention] The present invention allows easy measurement of engine oil consumption. [Embodiment] «First Embodiment" (Structure of Measurement Device 1) First, a configuration of an engine oil consumption amount measuring device , will be described with reference to Fig. 1, which is a specific embodiment of the present invention. Engine 2 is drawn separately in Figure 1. The engine 2 can then be installed in a vehicle, such as a motorcycle. The engine 2 can be built into a fixed type of device. Engine 2 can be of any type that uses any type of fuel. Preferably, however, the engine 2 is a fuel that uses a relatively small amount of sulfur component, such as =

The type of oil. A 137028.doc -9- 200946765 The measuring device 1 comprises a detecting tube holder 21, an exhaust gas introduction path 3, and a pump unit 27' having a flow integrator 3 as a flow measuring device, which can be used for detecting A sulfur dioxide detecting tube 22 of sulfur dioxide (S〇2) is disposed in the detecting tube holder 21. The configuration of each portion of the measuring device i will be more specifically explained below with reference to the drawings. The exhaust gas introduction path 3 introduces the exhaust gas of the engine 2 to the sulfur dioxide detecting tube 22' which is disposed in the detecting tube holder 2'. The exhaust gas introduction path 3 includes a pipe line 10, a filter 11, a line 12, a flow rate change control mechanism 13, a line 17, a sub-chamber 18, a line 19, and a throttle mechanism 2''. One end of the official line 10 is connected to the engine 2. Figure 1 shows the case where the pipeline is directly connected to the engine 2. However, for example, in the case where a muffler and the like are attached to the engine 2, the line 1〇 can be connected to the end of the muffler. In other words, the pipeline 10 is indirectly connected to the engine 2 either directly or via a muffler and the like. The other end of the line 1 is connected to the line 丨2 via the damper 11. The transition device 11 removes soot and the like contained in the exhaust of the engine 2. This prevents soot or the like from sticking to and accumulating in the downstream parts of the filter 11. The filter tether is detachably attached to lines 10 and 12. This facilitates the replacement of the filter u. The replacement of the chamber 15, each line, and each of the throttle mechanisms described later can also be easily accomplished. The filter 11 is not limited to a particular kind or configuration. For example, it can be a filter generally used for exhaust gas. The filter 11 may be of a type for absorbing the interference gas (also referred to as "coexisting gas") of the sulfur dioxide detecting tube 22. For example, the filter u may be of a type that prevents the interfering gas from reaching the sulfur dioxide detecting tube by reacting with the interfering gas 137028.doc 200946765 22. Alternatively, the filter cartridge may be of a type that prevents interference with the emulsion reaching the sulfur monoxide detecting tube 2 2 by absorbing the interfering gas. Lines 10 and 12 are not limited to a particular configuration, material, or the like. For example, lines 1 and 12 are preferably formed of a highly thermally conductive material. For example, preferred lines 10 and 12 are made of metal. In addition, copper is optimal for lines 1 and 12. In the first embodiment, the case where the lines 1 and 12 are made of copper will be described. The flow rate change control mechanism 13 is placed on the line 12. The flow change control mechanism 13 is a flow straightener. Specifically, the flow rate change control means 13 controls the change in the flow rate of the exhaust gas. More specifically, the flow rate change control mechanism 13 controls the exhaust pulsation, thereby straightening the flow rate of the exhaust gas. In the first concrete example, the case where the flow rate change control mechanism 丨3 is constructed by the throttle mechanism 14 provided on the middle portion of the line 12 and the chamber 15 provided at the end of the line 12 will be described. Specifically, the chamber 15 is internally visible to the transparent cavity. The chamber 15 has a compression force meter 16 disposed thereon to determine the pressure within the chamber 15. ❹ However, the flow rate change control mechanism 13 is not limited to this configuration. For example, the flow rate change control mechanism 13 can be constructed only by the throttle mechanism 14. The flow rate change control mechanism 13 can be constructed only by the chamber 15. The flow rate change control mechanism 13 can be formed by laminar flow forming means or capillary. Line 17 is connected to chamber 15. Subchamber 18 is connected to the end of line 17. The exhaust system from chamber 15 is directed into subchamber 18. Line 19 is connected to chamber 18. The line 19 supplies exhaust gas to the sulfur dioxide detecting tube 22 provided to the detecting tube holder 2j. The end of the sulfur dioxide detecting tube 22 can be inserted into the end of the line 193028.doc -11 - 200946765. Specifically, the end of the line 19 is formed of a flexible tube, such as a poly> The throttle mechanism 20 is disposed in the middle of the line 丨9. The supply of the exhaust gas to the sulfur dioxide detecting tube 22 is regulated by closing the throttle mechanism 20. On the other hand, the throttle mechanism 20 is opened to supply exhaust gas to the sulfur dioxide detecting tube 22. Further, the flow passage area of the line 19 is adjusted by the throttle mechanism 20 to adjust the flow rate of the exhaust gas supplied to the sulfur dioxide detecting tube 22. In the first embodiment, the detecting tube holder 21 is constructed by pairing the pair of facing plates 2 1 a and 21 b with each other facing each other. The sulfur dioxide detecting tube 22 is held between the butting plates 21a and 21b and thereby fixed. However, in the present invention, the debt measuring tube holding 21 is not limited to a specific member as long as it can fix the sulfur dioxide detecting tube 22. The measuring device 1 has an exhaust gas release path 4 provided therein for discharging the exhaust gas from the sulfur dioxide detecting tube 22 provided in the detecting tube holder 21. The exhaust gas release path 4 includes a line 24, a pump unit 27, a line 31, and an exhaust line 25. The line 24 is connected to the other end of the sulfur dioxide detecting tube 22 provided in the pick-up tube holder 21. The other end of the sulfur dioxide detecting tube 22 can be inserted into the end of the line 24, and the sulfur dioxide detecting tube 22 can be disposed at the end of the line 19 in a similar manner on the line 24. Specifically, the end of the line 24 is formed as a flexible tube, such as a polyfluorene tube. The throttle mechanism 23 is disposed in the middle of the line 24. The throttle mechanism 23 is closed to adjust the exhaust gas supply to the sulfur dioxide detecting tube 22. On the other hand, the throttle mechanism 23 is opened to supply the exhaust gas to the sulfur dioxide detecting tube 22. In addition, the flow passage area of the line 24 is adjusted by the throttle mechanism 23 to adjust the flow rate of the exhaust gas supplied to the sulfur oxide detecting tube 22 of the 137028.doc -12-200946765. Therefore, in the first embodiment, the flow rate of the exhaust gas supplied to the sulfur dioxide detecting tube 22 is adjusted by the throttle mechanisms 20 and 23. The downstream end of line 24 is connected to pump unit 27. The pump unit 27 includes a flow integrator 30, a pump 28, and a throttle mechanism 29. The flow integrator 3 is connected to the line 24. The flow integrator 30 integrates the flow rate of the exhaust flowing through line 24. The pump 28 is connected to the downstream side of the flow integrator 3〇. The throttle mechanism 29 is connected to the downstream side of the pump 28. Line 31 is connected to throttle mechanism 29. Line 31 is coupled to an exhaust conduit extending from subchamber 18. The exhaust gas introduced into the measuring device 1 is released to the outside of the measuring device i through the exhaust duct 25. The throttle mechanism 26 is disposed in a portion of the middle of the exhaust duct 25. The flow rate of the exhaust gas flowing through the exhaust duct 25 can be adjusted by the throttle mechanism 26. (Sulphur Dioxide Detection Tube 22) FIG. 2 is a plan view of the sulfur dioxide deficiency test tube 22 not used. As shown in Fig. 2, the sulfur dioxide detecting tube 22 is an ampoule sealed at both ends by welding. A detecting reagent 22f is enclosed between the closing members 22d and 22e in the sulfur dioxide detecting tube 22. The detection reagent 22f changes its color because of the reaction with the gas (sulfur dioxide) to be detected. The scale 22g is printed on a portion of the blocking detection reagent 22f. When the sulfur dioxide is used to detect the tube 2 2, the welded seals 22c at both ends are first cut by a glass cutter or the like. Next, gas is introduced through the gas inlet 22a. If the introduction gas contains sulfur dioxide, the color detection change occurs in the blocking detection reagent 22f. The color change of the detection reagent 22f starts from one side of the gas inlet 22a. In the case where the introduction of the sulfur dioxide detecting tube 22 137028.doc 200946765 contains a small amount of sulfur dioxide, the detection reagent 22f close to the gas population 22a undergoes a color change. When the gas introduced into the sulfur dioxide detecting tube 22 contains a relatively large amount of sulfur dioxide, the color of the detecting reagent 22f which is closer to the outlet 22b changes color. Typically, the detector tube presents an amount of gas directed to the assay. For example, for the sulfur dioxide detecting tube 22 shown in Fig. 2, the amount of gas introduced for the measurement is set to 100 ml. A gas system for detecting a predetermined introduction amount of the tube is introduced into the sulfur dioxide detecting tube 22, and the length of the detecting reagent 22f for changing the color thereof by visual observation is measured using a scale 22g printed on the sulfur dioxide detecting tube 22. Thereby, the amount of sulfur dioxide contained in the gas introduced into the sulfur dioxide detecting tube 22 is determined. For example, a gas of 丨〇〇ml is introduced into the sulfur dioxide detecting tube 22 shown in FIGS. 2 and 3, and the color change of the detecting reagent 22f reaches a portion of the printing first degree "1.8" as shown in FIG. In the case of 'determination of the introduction of gas containing 1.8 ppm of sulfur dioxide. Preferably, the color change of the detection reagent 22f is caused only by the gas to be detected. However, the color change of the detection reagent 22f does not have to be caused only by the gas to be detected. For example, the color change of the detection reagent 22f may occur due to contact with a gas other than the gas to be detected (sulfur dioxide). A gas system that does not detect the gas and causes a change in the color of the detection reagent 22f to interfere with the gas (coexisting gas). Preferably, in the presence of an interfering gas in which the detection reagent 22f is present, the measurement is completed in an environment having as little interference gas as possible. The detection reagent 22f is not limited to a specific species. The detection reagent 22f may be an agent whose basic reaction mechanism is an iodine-starch reaction. For example, 'detection reagent 22' may be a reagent whose basic reaction mechanism is a reduction reaction of iodate, a reaction of potassium iodate with a base, or a reduction reaction of dichromate. However, the most preferred detection reagent 22f is an agent whose basic reaction mechanism is an iodine-starch reaction. Specifically, the reagent preferably has the basic reaction mechanism of the following chemical equation (3). Now, the description will be made on the case where the detection reagent 22f is based on the reagent of the following chemical equation (3). S〇2+I2(blue-purple)+2H2〇—2HI(white)+H2S04 (3) Blue-purple iodine due to starch is reduced by sulfur dioxide and at its base _ This reaction mechanism is the detection of chemical equation (3) The inside of the reagent 22f becomes white hydrogen iodide. Thereby, the detection reagent 22f changes from blue-violet to white. Further, the basic reaction mechanism is that the detection reagent 22f of the chemical equation (3) changes from blue-violet to brown due to nitrogen dioxide. It is due to the release of nitrogen dioxide from the powder of the temple, which appears blue-purple angstroms and turns brown. At the same time, nitrogen monoxide does not cause the release of moths from the temple powder. Therefore, the basic reaction mechanism is that the color change of the detection reagent 22f of the equation (3) does not occur in the oxidation [ie, the basic reaction mechanism is the chemical reagent (3) detection reagent 22f will be © two Nitric oxide is regarded as an interference gas, but nitrogen monoxide is not regarded as an interference gas SA ^ yu spot 0 (measurement method of engine oil consumption using the measuring device 1). Next, reference will be made to FIG. 4 regarding the use of the measuring device i. The method of measuring the engine oil consumption is explained. As shown in FIG. 4, the engine 2 and the measuring device 1 are prepared first in step S1. In the case of the onboard type of the system, the setting of the vehicle and the configuration of the operator are simultaneously performed in step S1. For example, for the preparation of the measuring device, the following steps are carried out: the measuring device i 137028.doc -15· 200946765 is connected to the engine 2: the preparation and arrangement of the sulfur dioxide detecting tube 22: by the adjustment adjustment of the throttle mechanisms 14 and 26 Pressure in the device 1: The flow rate change is controlled by the adjustment of the throttle mechanism 14: the setting of the intake air amount entering the measuring device 1 and the setting of the flow rate extracted into the sulfur dioxide detecting tube 22. The control of the change in the flow rate of the exhaust gas can be accomplished by adjusting the throttle mechanism 14, so that the rocking of the pressure gauge 16 provided on the chamber 15 becomes small. The amount of intake air can be set in the actual measurement at the engine speed at which the measurement is completed. In the case where the engine 2 has an intake amount sensor, the amount of intake air can be continuously detected by monitoring the intake air amount sensor. Next, fuel is supplied (hereinafter referred to as "standard fuel") and the engine 2 is operated in step S2. The concentration of sulfur dioxide in the exhaust gas released during operation is determined in step S3. This measurement is hereinafter referred to as "first measurement". Specifically, in steps S2 and S3, the pump 28 is driven to open the throttle mechanisms 20, 23, and 29, and the exhaust gas is introduced into the sulfur dioxide detecting tube 22 in a state where the engine 2 is rotated at a predetermined speed. The flow extractor 3 monitors the total amount of exhaust gas extracted into the sulfur dioxide detecting tube 22. When the flow integrator 30 indicates that the amount of exhaust gas flowing through the sulfur dioxide detecting tube 2 2 reaches a predetermined amount to be extracted into the sulfur dioxide detecting tube 22, the throttle mechanism 2 is turned off, and the like, and the step S3 is completed. The engine speed of the engine 2 in step S3 is not limited to a specific speed. However, the engine speed of the preferred system engine 2 in step S3 is substantially realized in the case where the nitrogen dioxide detects the detection reagent 22f as an interference gas (for example, as the basic reaction mechanism is an iodine-resin reaction reagent). highest. In other words, the preferred 137028.doc -16-200946765 completes step S3 in a state where the engine 2 is rotated at substantially the highest speed. After the sulfur dioxide detecting tube 22 is separated from the measuring device 1, the concentration of sulfur dioxide can be obtained by visual observation of the sulfur dioxide detecting tube 22. Next, 'in step S4', a fuel in which engine oil is mixed with standard fuel at a prescribed ratio (hereinafter referred to as "mixed fuel") is supplied to operate the engine 2. The mixing ratio of the engine oil to the mixed fuel is not limited to A specific value. For example, it may be about %1% to 2%. The mixing ratio of engine oil to mixed fuel is 1% in this embodiment. Next 'the sulphur dioxide in the exhaust gas released by the above operation. The concentration is determined in step S5. Hereinafter, the measurement is referred to as "second measurement." The specific procedure of the first measurement is similar to the first measurement. Similar to the first measurement, the engine speed is not limited to a specific one in the second measurement. Speed. However, the actual maximum engine speed is better. In addition, in the second measurement, after separating the sulfur dioxide detecting tube 22 from the measuring device, the sulfur dioxide concentration data can be obtained by visual observation of the sulfur dioxide detecting tube 22. Next, the engine oil consumption is calculated based on the results of the first and second determinations in step %. The engine oil is calculated by the following equations (1) and (2). The amount of consumption, which will be explained later. LOC = {(SO-g)/(Sl-SO+g)}.GR (1) g=(Sl-S0)/( α-l) (2) In the equations Medium, LOC: engine oil consumption (g/h) G: amount of fuel used in the second measurement step (g/h) R: ratio of engine oil to mixed fuel 137028.doc 17- 200946765 s〇: at Concentration of sulphur dioxide detected in the first measurement step (ppm) S1. Concentration of sulphur dioxide detected in the second measurement step (concentration of sulphur dioxide produced by combustion of fuel (ppm) α : (by Concentration of sulphur dioxide produced by combustion of a mixed fuel) / (concentration of sulphur dioxide produced by combustion of fuel) (calculation method of engine oil consumption), said month, 'concentration of sulphur dioxide in exhaust gas when using standard fuel And the concentration of sulfur dioxide in the exhaust gas when using the mixed fuel is used in the calculation method of the engine oil consumption according to this embodiment. Because there is a case where not only the engine oil contains a sulfur component but also the fuel itself contains a sulfur component, in this way a few calculations to reduce the damage attributed to the fuel itself The measurement error of the composition and the improvement of the measurement accuracy. As shown in Fig. 5, the concentration of sulfur dioxide in the exhaust gas S0 [ppm] is the concentration of sulfur dioxide generated from the engine oil when the standard fuel is used [ppm] It is called the sum of the concentration of sulfur dioxide generated from the fuel. If the concentration of sulfur oxide [g] obtained from the fuel is known, the sulfur dioxide concentration S0 [PPm] measured in the first measurement can be accurately calculated from the engine oil. A concentration of sulfur oxides A[PPm] (i.e., A = S0-g) is produced. However, it is not necessary to know the amount of sulfur component in the fuel. Therefore, in this embodiment, the results of the first and second determinations are used for The concentration g [ppm] of sulfur dioxide generated from the fuel is estimated, and the measurement error due to sulfur dioxide generated from the fuel is reduced. As shown in Figure 5, the concentration of sulfur dioxide in the mixed fuel 81 [1) 1) 111] is the sulfur dioxide produced by the engine oil, the degree of sulfur dioxide [A], the fuel produced by the two 137028.doc • 18-200946765 sulfur oxide The concentration g [ppm] and the concentration B [ppm] of the sulfur dioxide produced from the Gongyi engine oil mixed in the fuel. Now, the flow rate G [g/h] of the fuel in the second measurement is known. Therefore, if the mixing ratio of the engine oil is R, the flow rate of the engine oil in the fuel is G_R [g/h]. Therefore, this means that B + g = (Sl - S0) + g [ppm] of sulfur dioxide is detected from engine oil having a flow rate of G.R [g/h]. The ratio of the engine oil to the detected sulfur dioxide is (G*R)/(Sl-SO+g). Meanwhile, if the engine oil consumption enclosed in the engine 2 is LOC [g/h], the ratio between the engine oil amount and the detected sulfur dioxide is LOC/(SO-g). Since the above ratios are equal to each other, the equation is (G*R) / (Sl_SO + g) = LOC / (SO - g). Therefore, it is expressed as LOC = {(SO-g)/(Sl-SO+g)}.G.R, as in equation (1). The ratio between the concentration of sulfur dioxide produced by combustion of the mixed fuel and the concentration of sulfur dioxide produced by combustion of the standard fuel is α, ot = (Sl - S0 + g) / g. Therefore, this equation is expressed as g = (sls 〇) / (a - 1), as in equation (2). The concentration of sulfur dioxide produced by combustion of a standard fuel and the concentration of sulfur dioxide produced by combustion of a mixed fuel can be obtained by a previously completed analysis and the like. Therefore, the ratio sense is given in advance as a prescribed value. (Effects of Specific Embodiments) This specific embodiment allows a more accurate measurement of engine oil consumption due to consideration of the influence of sulfur dioxide generated from the fuel itself. Although the concentration of sulfur dioxide produced from the fuel itself is unknown, this embodiment allows the engine to be accurately/determined by consumption 1. This particular embodiment is clearly particularly effective in situations where the concentration of sulfur oxides from the fuel itself is relatively large. 137028.doc 200946765 Further, the following effects can be obtained by using this specific embodiment. According to the measuring device having the sulfur dioxide detecting tube 22, the measurement of the engine oil consumption can be promoted by using the sulfur dioxide detecting tube 22. In particular, the measuring device 1 does not require relatively complicated preparation for the measurement, such as pre-measurement gas calibration in conventional sulfur tracking devices. The measurement of the engine oil consumption can be started immediately by the measuring device 1 only by completing the simple preparation for the enthalpy, which is the adjustment of the flow rate of the exhaust gas.

Oil consumption is low. Therefore, in the case where the engine oil consumption is measured by the measuring device i, as in the gravity measuring method or the sampling method, it is determined that the engine oil is not affected by the dilution of the water or the gasoline. Therefore, the engine oil consumption can be measured relatively accurately by the measuring device 3. In addition, the 'snap set' requires a relatively long measurement period, for example, several hours to several tens of hours in the force measurement method and the sampling method. The quantitative exhaust gas is extracted to determine the oxidation in the skirt. Remaining tube:

The engine oil consumption is measured in a relatively short period of time, such as minutes to tens of minutes. The measuring device 1 has a construction number of a threshold number and is small in size and a conventional S-trace device. Defining the inner dimensions of the square meters; for example, the measuring device 1 can be transported relatively easily in less than the device. For the conventional S-travel device, for example, the fixed type engine can be made relatively easy to make. . In addition, the acquisition of the engine oil consumption is, for example, a motorcycle, for example, in the case of a relatively small vehicle, the "measuring device 2 is installed in the vehicle and the engine oil consumption is measured when the vehicle is running 137028.doc -20· 200946765 The measuring device 1 is relatively inexpensive compared to the conventional s-trace device. The measuring device does not require a gas supply member for supplying a gas (for example, hydrogen) for measurement in the measurement of the engine oil consumption. In addition, the sulfur dioxide detector The measuring tube η is relatively inexpensive. Therefore, the 'fitting 41 allows for a reduction in the investment in equipment for measuring the consumption of the poultry oil. In addition, the operating cost of the engine oil consumption measurement can be reduced.

Further, the measuring device 1 facilitates the replacement of the chambers 15 and 18 and the throttle mechanism 14. Therefore, the chamber 15 and the like can be easily replaced in the case of the construction member of the exhaust smudge measuring device. In other words, the measuring device 丨 promotes the maintenance of β. When the engine oil consumption is measured by the measuring device i, the amount of the exhaust gas flowing through the sulfur dioxide detecting tube 22 is accurately measured. This is because the engine oil consumption is calculated based on the amount of exhaust flowing through the sulfur dioxide detecting tube 22. Typically, the pulsations are generated with the exhaust of the engine 2. In other words, the flow rate of the exhaust gas released from the engine 2 is not always constant. Therefore, in the case where the sulfur dioxide detection f 22 is directly connected to the engine 2, it may be difficult to accurately measure the amount of exhaust gas flowing through the sulfur dioxide detecting tube 22 by the flow integrator 30. As a result, it may be difficult to accurately calculate the engine oil consumption. On the other hand, the flow rate change control means 丨3 in the measuring device 1 controls the flow rate change of the exhaust gas, for example, pulsation. Therefore, the amount of exhaust gas flowing through the sulfur dioxide detecting tube 22 can be measured relatively accurately. Therefore, the measuring device 1 allows a relatively accurate calculation of the engine oil consumption. Preferably, the flow rate change control means 13 is disposed upstream of the sulfur monoxide detecting tube 2 2 from the viewpoint of effective control of the flow rate change. However, the flow rate change 137028.doc -21 - 200946765 The setting of the control mechanism 13 is not limited to a specific position. For example, the flow rate change control mechanism 13 may be disposed downstream of the sulfur dioxide detecting tube 22. The flow rate change control mechanism 13 is also not limited to a specific configuration. However, as in the first embodiment, the preferred flow rate change control mechanism 丨3 is constructed with the throttle mechanism 14 and the chamber 15. Thereby, the cost of the flow change control mechanism 13 can be saved. In addition, this facilitates the replacement of the flow rate change control mechanism 13, thereby improving its maintenance facilities. The pump 28 is placed downstream of the sulfur dioxide detecting tube 22 in the measuring device 1. The pump 2 8 extracts the exhaust gas flowing through the sulfur dioxide detecting tube 22 in the step of measuring the sulfur dioxide concentration. This further stabilizes the flow rate of the exhaust gas flowing through the sulfur dioxide detector 22. As a result, the amount of exhaust gas flowing through the sulfur dioxide detecting tube 22 can be measured with respect to the quasi-marriage. Therefore, the measuring device 1 allows a more accurate calculation of the engine oil consumption. Preferably, the step of measuring sulfur dioxide in the exhaust gas is carried out in a state where the engine 2 is substantially rotated at the highest speed. This results in a relatively large amount of fuel in the air-fuel mixture supplied to the engine. Therefore, the oxygen concentration in the combustion chamber of the engine 2 can become relatively low. This prevents the generation of the dioxide gas (N〇2), which is the interference gas of the iodine-starch reaction sulfur dioxide detecting tube 22. Therefore, it is possible to achieve a more accurate determination of the concentration of sulfur dioxide in the exhaust gas. In this particular embodiment, lines 10 and 12 are formed from a highly thermally conductive material. Specifically, 'lines 10 and 12 are formed of copper. Therefore, the exhaust from the engine 2 can be effectively cooled in the lines 1 and 12. This allows control of the amount of water contained in the exhaust. Water condensation is intercepted by the chamber 15 and water is prevented from entering the sulfur dioxide credit tube 22 from 137028.doc -22-200946765. In addition, water condensate can be observed because the chamber 15 is transparent in the first embodiment. In the 匕-body embodiment, the measurement between the operation of supplying normal fuel (i.e., standard fuel) and the measurement of the operation of the engine 2 when supplying the mixed fuel are compared with each other. In other words, a comparison between the two operations can reduce the disturbance effect on the engine oil consumption measurement. Example: As shown in Fig. 6, the water vapor in the exhaust gas is opposite to the sulfur dioxide: = and the sulfur dioxide concentration generally decreases as the temperature of the exhaust gas decreases. If the ambient temperature of the measuring device 1 changes from the assumed temperature, the measurement error tends to occur. For example, “J疋铗 difference can occur due to changes in ambient temperature between π in summer and winter. However, according to this specific implementation, the operation of supplying standard fuels and supplying mixed fuels is:],: The measurement error caused by the change of the ambient temperature can be maintained. This allows the engine oil consumption to be more accurately measured. The sound is connected to the body and is not required before the oil consumption is _ Clearly know the engine oil, etc. The measurement of the embodiment of the ❹ 县 县 实施 实施 = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = EXAMPLES In the two-body embodiment, the description may be made regarding the setting of the sulfur dioxide price measuring tube. However, the present invention is not limited to this configuration. For example, the measuring device may be set to a plurality of (four) measuring words, and the measuring device may be α.宕 ", 1, indeed in the second embodiment of the second test up to five debt measuring devices. Word > Figure 7 shows a detailed description of the measuring device la that can be set up with three detection tubes J37028.doc •23- 200946765. In the description of the second embodiment, the constituent elements having substantially equivalent functions will be denoted by the common reference numerals and symbols' and the description thereof will be omitted. As shown in FIG. 7, the detecting tube holders 41 and 61 are disposed in the measuring device 1& together with the detecting tube holder 21 according to the second embodiment. Lines 19a, 19b, and 19c are again disposed within sub-chambers 18 to 18. The line 19a is connected to a detecting tube set in the detecting tube holder 21. The line 19b is connected to a detecting tube set in the detecting tube holder 41. The line 19c is connected to a detecting tube set in the detecting tube holder 61. In addition, the pipelines 24a, 24b, and 24c' are provided for the detection tube disposed in the detection tube holder 21, the detection tube disposed in the detection tube holder 41, and the detection tube holder 61. The detection tube inside is connected to the pump unit 27. The throttle mechanisms 2A, 2B, 20c, 23a, 23b' and 23c are disposed in the lines 19a, 19b, 19c, 24a, 24b, and 24c, respectively. For example, in the case where the measurement of the engine oil consumption is performed only in the case where the sulfur dioxide detecting tube 22 is set in the detecting tube holder 21, similar to the first embodiment, the throttle mechanism 20b, 2 is closed. The determination of the concentration of sulfur dioxide is carried out in the case of 〇c, 23b, and 23c. In the case where the engine oil consumption measurement is completed with the detection tube set to all of the detection tube holders 21, 41, and 61, all the throttle mechanisms 2a, 20b, 20c, 23a are opened. The determination of sulfur dioxide is completed in the case of 23b ' and 23c. The detector tube holders 41 and 61 may be tube holders in which the interference gas detecting tube 42 for detecting the interference gas of the sulfur dioxide detecting tube 22 is set together with the sulfur dioxide detecting tube 22 137028.doc -24-200946765 . Specifically, in the case of the basic reaction mechanism of the iodine-starch reaction system sulfur dioxide detecting tube 22, the detecting tube holders 41 and 61 may be interfering gas detecting tubes 42 which can be set for detecting nitrogen dioxide. Tube holder. Hereinafter, in the second embodiment, a description will be given of a case where the detecting tube holder 41 is a tube holder in which the interference gas detecting tube 42 can be set. (Test method for engine oil consumption using the measuring device 1a) In this embodiment, the engine oil consumption is measured in a manner generally similar to that of the first embodiment (see Fig. 4). However, in this embodiment, the correction is correctly performed in consideration of the influence of the interference gas in the first and second measurements as shown in Fig. 8. In this embodiment, the determination of the concentration of sulfur dioxide and the concentration of the interfering gas are simultaneously performed during the first and second measurement periods (see step S20). Specifically, the sulfur dioxide detecting tube 22 and the interference gas detecting tube 42 are respectively set in the detecting tube holder 21 in the state in which the throttle mechanisms 20a, 20b, and 20c and the throttle mechanisms 23a, 23b, and 23c are closed. The tube holder 41 is detected. Next, the throttle mechanism 20a and 20b and the throttle mechanisms 23a and 23b are opened while the engine 2 is operating at a predetermined engine speed, and the exhaust gas is introduced into the sulfur dioxide detecting tube 22 and the interference gas detecting tube 42. When the flow integrator 30 indicates that the amount of exhaust gas flowing through the sulfur dioxide detecting tube 22 and the interfering gas detecting tube 42 reaches a predetermined amount to be extracted into each of the detecting tubes, the throttle mechanisms 20a, 20b, etc. are closed. And so on, and step S20 is completed. At this time, the ratio between the flow rate of the exhaust gas in the sulfur dioxide detecting tube 22 and the flow rate of the exhaust gas in the interfering gas detecting tube 42 is not limited to a specific ratio. For example, the ratio of the flow rate of the exhaust gas in the test tube 22 to the flow rate of the exhaust gas in the interfering gas detecting tube 42 can be set equal to the extraction to the sulfur dioxide detecting tube 22, in the case of the dioxane 137028.doc -25-200946765. The ratio of the predetermined amount of gas within the gas to the predetermined amount of gas extracted into the interfering gas detecting tube 42. Thereby, the integrated flow rate of the exhaust gas flowing through each of the sulfur dioxide debt detecting tube 22 and the interfering gas detecting tube 42 can be obtained by the flow integrator 3〇. In the case where a plurality of detecting tubes are set for a single measurement as in this embodiment, the flow integrator can be individually set for each detecting tube. The measurement of the concentration of sulfur dioxide and the concentration of the interfering gas can be sequentially performed in step S20. Specifically, for example, the measurement is performed in such a manner that the sulfur dioxide concentration is measured in the case where only the throttle mechanisms 20a and 23a are opened, and then the throttle mechanisms 20a and 23a are closed to open the throttle mechanisms 2〇b and 23b, and the measurement is performed. Interference gas concentration. In this embodiment, the step S21 is performed after the step S21, as shown in Fig. 8. After the step S21, it is determined whether the concentration of the interference gas detected by the interference gas debt detecting tube 42 in the step S2 is equal to or lower than the predetermined concentration. Specifically, in step S21, it is determined whether the interference gas concentration measured by the interfering gas gas sampling tube 42 in step S20 is equal to or lower than the maximum interference gas concentration preset for the sulfur dioxide detecting tube 22. In other words, it is determined whether the concentration of the interfering gas contained in the exhaust gas is within the range usable by the sulfur dioxide detecting tube 22. In step S21, if it is determined that the concentration of the interference gas detected by the interference gas detecting tube 42 is the maximum interference gas concentration preset for the sulfur dioxide detecting tube 22, the measurement jumps to step S22. On the other hand, if it is determined that 137028.doc -26- 200946765 the interference gas concentration detected by the interference gas detecting tube 42 is higher than the maximum interference gas concentration preset for the sulfur dioxide detecting tube 22 in step S21, then no Step S22, and the test is completed. In other words, the calculation of engine oil consumption is stopped in this case. In step S22, the measured value is corrected based on the interference gas concentration measured in step S20. The calibration is based on the relationship between the predetermined interference gas concentration and the correction value. This allows the engine oil consumption to be calculated in consideration of the interfering gas concentration. The relationship between the interfering emulsion concentration and the correction value can be determined by a pre-completed experiment in which a gas mixture in which the interfering gas and the gas to be detected are mixed at a prescribed ratio passes through the sulfur dioxide detecting tube 22. (Effects of Specific Embodiments) A plurality of detecting tube holders 21, 41, and 61 are provided in the measuring device 1a according to the second embodiment. Therefore, the measurement can be completed by setting a plurality of detection tubes together in the case of the measuring device. Therefore, the concentration of a plurality of types of gases can be measured once as needed. As a result, the measuring device 1a allows measurement of other components in the exhaust gas while calculating the engine oil consumption. For example, measurement of the concentration of sulfur dioxide and the concentration of interfering gas can be simultaneously performed by the measuring device 1a. Further, for example, the measurement of the concentration of sulfur monoxide can be carried out by setting a plurality of the quartz dioxide measuring tubes 22 in the apparatus. This will further improve the accuracy of the calculation of engine oil consumption. In the measurement of the consumption of the engine oil in this embodiment, the measured value is corrected in step s22 based on the interference gas concentration measured in step S2G. 137028.doc •27· 200946765 This allows the deterioration of the accuracy of engine oil consumption measurement due to interfering gases to be prevented. In other words, the engine oil consumption can be measured more accurately. If it is determined in step S21 that the concentration of the disturbance gas contained in the exhaust gas is higher than the predetermined concentration, the calculation of the engine oil consumption amount is stopped. Therefore, the reliability of the calculated engine oil consumption can be improved. In this embodiment, the engine oil consumption is calculated in the case where the concentration of the disturbance gas contained in the exhaust gas is equal to or lower than the prescribed concentration in step S21. However, in the case where more accurate engine oil consumption is required, the calculation of the engine oil consumption can be stopped if the disturbance gas is detected in step S2. «Third embodiment" In the first and second embodiments, the operator of the measuring device calculates the If shape of the engine oil 4 by himself/herself or by using a computing device separate from the measuring device. .

In other words, in the third embodiment, the throttle mechanism 20a, 20b is automatically opened or closed by the driver 53. And 20c ° In this embodiment, the operator of the measuring device 1b borrows each of the settings from the operation input portion 52 to the processing unit 50 (see Fig. 4) in step S1. Specifically, the operator inputs In step S20, the amount of exhaust gas (Q) in the sulfur dioxide detection tube 22, the integrated flow rate of the exhaust gas extracted into the sulfur dioxide detecting tube 22, and the relationship between the interference gas concentration and the correction value are extracted. Next, at step In S20 (see Fig. 8), the operator of the measuring device 1b operates the input portion 52, whereby the processing unit 50 outputs a throttle opening signal to the driver 53. Thereby, the throttle mechanisms 20a and 20b are opened, and the sulfur dioxide concentration is started. The processing unit 50 monitors the flow integrator 30 in step S20. When the flow integrator 30 detects the integrated flow rate of the exhaust gas extracted into the sulfur dioxide detecting tube 22, the processing unit 50 outputs a throttle mechanism closing signal to the driver. 53. The throttle mechanisms 20a and 20b are closed, and the measurement of the sulfur dioxide concentration is completed. The operator of the measuring device 1b visually observes the sulfur dioxide detecting tube 22 and the interference gas detecting tube 42 after completing the step S20, thereby obtaining the row. The concentration of sulfur dioxide in the gas and the concentration of the interfering gas. The operator operates the input portion 52 to input the obtained concentration of sulfur dioxide and the concentration of the interfering gas to the processing unit 50. Thereby, the processing unit 50 automatically performs step S21, step S22, and step S6. 137028.doc -29- 200946765 Specifically, the processing unit 50 first determines in step S21 whether the interference gas concentration in step S20 is At or below a predetermined concentration. If the decision Cloth interfering gas concentration is higher than the predetermined concentration in the step S2〇, the display 51 displays the measurement can not be completed engine oil consumption amount (symbol "NG"), and the measurement is stopped. At the same time, if it is determined that the interference gas concentration in step S2 is the prescribed concentration in step S21 or lower, the processing unit 50 is based on the interference gas concentration and the correction value.

The relationship corrects the measured value. The processing unit 50 calculates the engine oil consumption amount based on the above-described equations (1) and (2) in step S6. The corrected engine oil consumption is displayed on the display 51. The processing unit 50, the display 51, the input portion 52, and the driver 53 can be specifically used to measure the items of the shock lb.
