In first embodiment, sound-pipe support 21 is made of a pair of adjacent panels 21a respect to one another and 21b.Thereby sulfur dioxide sound-pipe 22 is supported between adjacent panels 21a and the 21b and is fixed.Yet in the present invention, sound-pipe support 21 is not limited to concrete member, needs only its fixedly sulfur dioxide sound-pipe 22.
Be provided with toxic emission path 4 in the measuring device 1, be used for discharging waste gas from the sulfur dioxide sound-pipe 22 that is arranged on sound-pipe support 21.Toxic emission path 4 comprises pipeline 24, pump unit 27, pipeline 31 and outlet pipe 25.Pipeline 24 is connected to the other end of the sulfur dioxide sound-pipe 22 that is arranged in the sound-pipe support 21.One end of sulfur dioxide sound-pipe 22 can insert an end of pipeline 24, with that end of pipeline 19 similarly, sulfur dioxide sound-pipe 22 is installed to an end of pipeline 24.Particularly, this end of pipeline 24 forms for example flexible pipe of silicone tube.

(sulfur dioxide sound-pipe 22)
Fig. 2 is the planimetric map of untapped sulfur dioxide sound-pipe 22.As shown in Figure 2, sulfur dioxide sound-pipe 22 is ampoule bottles of the soldered sealing in two ends.Enclosed detection reagent 22f between envelope parts 22d in the sulfur dioxide sound-pipe 22 and the 22e.When with the gas that will survey (sulfur dioxide) when contacting, survey reagent 22f owing to react and change color.Be printed with scale 22g at the position of enclosing detection reagent 22f.
When using sulfur dioxide sound-pipe 22, at first cut the welded seal 22c at two ends with glass cutter etc.Then, introduce gas by suction port 22a.If comprise sulfur dioxide in the gas of introducing, change in color will take place in the detection reagent 22f that is enclosed.Survey the side of the change in color of reagent 22f from contiguous suction port 22a.Comprise a spot of sulfur dioxide if be incorporated in the gas of sulfur dioxide sound-pipe 22, survey the contiguous suction port 22a of change in color of reagent 22f.As if comprising more sulfur dioxide in the gas that is incorporated into sulfur dioxide sound-pipe 22, the change in color of surveying reagent 22f is positioned at the position of more contiguous outlet 22b.
Usually, sound-pipe marks the gas flow that is used to measure and will introduces.For example, being used to measure of sulfur dioxide the sound-pipe 22 shown in Figure 2 and gas flow introduced is set as 100 milliliters.The gas that will have the default introducing amount of sound-pipe is incorporated into sulfur dioxide sound-pipe 22, and the length of reading the detection reagent 22f of variable color by the scale 22g that is printed on the sulfur dioxide sound-pipe 22, thereby judge the content of the sulfur dioxide in the gas of introducing sulfur dioxide sound-pipe 22.For example, if 100 milliliters gas is introduced into Fig. 2 and sulfur dioxide sound-pipe 22 shown in Figure 3, and survey reagent 22f1 variable color to as shown in Figure 3 printing the position of scale " 1.8 ", can judge the sulfur dioxide that comprises 1.8ppm (1.8/1000000) in the gas of introducing.
Preferably, only cause the variable color of surveying reagent 22f by the gas that is detected.Yet the variable color of surveying reagent 22f is not necessarily only caused by the gas that is detected.The variable color of for example surveying reagent 22f can be by contacting with the gas that is detected (sulfur dioxide) gas in addition and causing.Not the gas that is detected and to make the gas of surveying reagent 22f variable color be interference gas (coexistence gas).Preferably, if the interference gas of surveying reagent 22f is arranged, measurement should be carried out in the environment with the least possible interference gas.
Survey reagent 22f and be not limited to concrete kind.Surveying reagent 22f can be that its fundamental reaction mechanism is the reagent of starch-iodine reaction.For example, surveying reagent 22f can be that its fundamental reaction mechanism is the reagent of potassium iodate reduction reaction, potassium iodate and alkali reaction or dichromate reduction reaction.Yet most preferably, surveying reagent 22f is that its fundamental reaction mechanism is the reagent of starch-iodine reaction.Particularly, reagent preferably has the fundamental reaction mechanism of following chemical equation (3).Now, the description here will be the situation of its fundamental reaction mechanism for the reagent of following chemical equation (3) at surveying reagent 22f.
SO

2(bluish violet)+2H
2O → 2HI (white)+H

In fundamental reaction mechanism is among the detection reagent 22f of chemical equation (3), meets starch and is hepatic iodine is reduced and produce white by sulfur dioxide hydrogen iodide.Therefore, survey reagent 22f and become white from bluish violet.In addition, to make fundamental reaction mechanism be that the detection reagent 22f of chemical equation (3) becomes brown from bluish violet to nitrogen dioxide.This is because nitrogen dioxide makes chance starch be hepatic iodine to be discharged from starch, and it is brown that it is become.Simultaneously, nitrous oxide can not make iodine discharge from starch.Therefore, can not make fundamental reaction mechanism be the detection reagent 22f variable color of chemical equation (3) to nitrous oxide.That is, fundamental reaction mechanism be the detection reagent 22f of chemical equation (3) with nitrogen dioxide as interference gas, but not with nitrous oxide as interference gas.
(adopting the method for measurement of the engine consumption of measuring device 1)
Next, the method for measurement of the engine consumption that adopts measuring device 1 is described with reference to Fig. 4.
As shown in Figure 4, at first in step S1, prepare motor 2 and measuring device 1.If motor 2 is vehicle-mounted type (onboard type), carry out the adjusting of vehicle and operator's layout among the step S1 simultaneously.
For example, the preparation of carrying out measuring device 1 is as follows: measuring device 1 is linked to each other with motor 2, prepare and place sulfur dioxide sound-pipe 22, regulate pressure in the measuring device 1 by regulating throttle mechanism 14 and 26, change by regulating throttle mechanism 14 control flow rate, intake in the setting measurement device 1, and set the flow velocity that sucks in the sulfur dioxide sound-pipe 22.Can control the changes in flow rate of waste gas by regulating throttle mechanism 14, thereby reduce to be installed in the swing of the pressure meter 16 on the chamber 15.In actual measurement, can the speed of motor set intake when measuring.If motor 2 has the air quantity of suction sensor, then can constantly survey intake by monitoring the intake sensor.
Next, fuel (being called " reference fuel " afterwards) is provided, and motor 2 is moved in step S2.Measure the concentration of the sulfur dioxide in the run duration exhaust gas discharged among the step S3.Hereinafter, this measurement is called " first measures ".
Particularly, in step S2 and S3, driven pump 28 is opened throttle mechanism 20,23 and 29, begins waste gas is introduced sulfur dioxide sound-pipe 22 under the state of motor 2 with the rotating speed rotation of regulation.Suck the total amount of the waste gas of sulfur dioxide sound-pipe 22 by 30 monitorings of flow integrator.When flow integrator 30 indicates the amount of the waste gas that flows through sulfur dioxide sound-pipe 22 to reach the predetermined amount that should suck sulfur dioxide sound-pipe 22, close throttle mechanism 20, and step S3 finishes.
The engine speed of motor 2 is not limited to concrete speed among the step S3.Yet, preferably, if fundamental reaction mechanism for example be in the reagent of starch-iodine reaction nitrogen dioxide as interference gas influence survey reagent 22f, the engine speed of motor 2 is the highest basically among the step S3.In other words, preferably, make step S3 be in the state that motor 2 rotates with the highest speed basically.
With sulfur dioxide sound-pipe 22 after separating from the measuring device 1, can be by reading the concentration data that sulfur dioxide sound-pipe 22 obtains sulfur dioxide.
Next, in step S4, prepare engine oil and reference fuel the mixed fuel of ratio (being called " fuel combination " afterwards) with regulation.Provide fuel combination so that motor 2 operations.The ratio that engine oil is mixed into fuel combination is not limited to occurrence.For example, can be about 0.01% to 20%.To be mixed into the ratio of fuel combination be 1% to engine oil in the present embodiment.
Next, in step S5, measure the concentration of sulfur dioxide in the above-mentioned operation institute exhaust gas discharged.Hereinafter, this measurement is called " second measures ".Second detailed process of measuring is similar to first and measures.Similar with first measurement, the speed of motor is not limited to concrete speed in second measurement.Yet, preferably the highest basically engine speed.Equally in second measures, with sulfur dioxide sound-pipe 22 after separating from the measuring device 1, can be by reading the concentration data that sulfur dioxide sound-pipe 22 obtains sulfur dioxide.
Next, in step S6, based on first and second oil consumption of calculation engine as a result of measuring.The consumption of engine oil is calculated according to following formula (1) and (2), below will describe in detail it.
LOC＝{〔S0-g〕/〔S1-S0+g〕}·G·R (1)
g＝〔S1-S0〕/〔α-1〕 (2)
In formula,
LOC: engine consumption (g/h)
G: the fuel combination amount of using in second measurement procedure (g/h)
R: engine oil accounts for the ratio of fuel combination
S0: the concentration of the sulfur dioxide of surveying in first measurement procedure (ppm)
S1: the concentration of the sulfur dioxide of surveying in second measurement procedure (ppm)
G: the concentration (ppm) of the sulfur dioxide that fuel combustion produces
α: (concentration of the sulfur dioxide that mixed fuel firing produces)/(concentration of the sulfur dioxide that fuel combustion produces).
(computational methods of engine consumption)
As mentioned above, in the computational methods according to the engine consumption of present embodiment, the concentration of sulfur dioxide in the waste gas when having used when adopting reference fuel the concentration of sulfur dioxide in the waste gas and having adopted fuel combination.Owing to have not only that engine oil comprises the sulphur composition, and fuel itself also comprises the situation of sulphur composition, calculate by this way to reduce the measurement error that the sulphur composition brings in the fuel itself, and the raising measuring accuracy.
In other words, as shown in Figure 5, when adopting reference fuel in the waste gas concentration S0 (ppm) of sulfur dioxide be the summation of the concentration g (ppm) of the sulfur dioxide that produces of concentration A (ppm) and the fuel of the sulfur dioxide that produces of engine oil.If the concentration g (ppm) of the sulfur dioxide that fuel produces is known, the concentration A (ppm) of the sulfur dioxide that engine oil produces can accurately be calculated (that is, A=S0-g) by the concentration S0 (ppm) of first sulfur dioxide that records.Yet the content of sulphur composition is not necessarily known in the fuel.Therefore, in the present embodiment, the concentration g (ppm) of the sulfur dioxide that first and second results that measure are used to estimate that fuel produces and reduce the measurement error that sulfur dioxide that fuel produces brings.
As shown in Figure 5, the concentration S1 of sulfur dioxide (ppm) is the concentration g (ppm) of the concentration A (ppm) of the sulfur dioxide that produces of engine oil, sulfur dioxide that fuel produces and the summation that is blended in the concentration B (ppm) of the sulfur dioxide that the engine oil in the fuel produces in the fuel combination.Now, the flow velocity G (g/h) of fuel is known in second measurement.Therefore, if the proportions of ingredients of engine oil is R, the flow velocity of engine oil is GR (g/h) in the fuel.Therefore, this means that flow velocity is the sulfur dioxide that detects B+g=S1-S0+g (ppm) in the engine oil of GR (g/h).The amount of engine oil is (GR)/(S 1-S0+g) with the ratio of the sulfur dioxide that detects.Simultaneously, if the engine consumption of enclosing in the motor 2 is LOC (g/h), the amount of engine oil is LOC/ (S0-g) with the ratio of the sulfur dioxide that detects.Because two above ratios are equal to each other, and obtain equation (GR)/(S1-S0+g)=LOC/ (S0-g).Correspondingly, can be expressed as LOC={ (S0-g)/(S1-S0+g) in the equation (1) } GR.
If the concentration of the sulfur dioxide that mixed fuel firing produces is α with the ratio of the concentration of the sulfur dioxide of reference fuel burning generation, α=(S1-S0+g)/g so.Therefore, equation is expressed as g=(S1-S0)/(α-1) in the equation (2).
The acquisitions such as analysis that the concentration of the sulfur dioxide that the concentration of the sulfur dioxide that the reference fuel burning produces and mixed fuel firing produce can be done by shifting to an earlier date.Therefore, ratio α is provided in advance as specified value.
(embodiment's effect)
Because considered the influence of the sulfur dioxide that fuel itself produces, present embodiment can be measured engine consumption more accurately.Although the concentration of the sulfur dioxide that fuel itself produces is unknown, present embodiment can accurately be measured engine consumption.If the concentration of the sulfur dioxide that fuel itself produces is relatively large, present embodiment is very effective undoubtedly.
In addition, present embodiment can obtain following effect.
According to measuring device 1 with sulfur dioxide sound-pipe 22, the user of sulfur dioxide sound-pipe 22 the measurement of engine consumption.Especially, measuring device 1 did not need to carry out preparing (demarcating as gas) as the measurement of the relative complex in traditional sulphur tracking means before measuring.As long as simply measure preparation, promptly regulate the flow velocity of waste gas, just can begin to measure engine consumption immediately with measuring device 1.
Measuring device 1 is measured engine consumption by using the sulphur that contains in the engine oil.Therefore, if measure engine consumption with measuring device 1, measuring not can be by oil dilution influences to motor as the water in analysis by weight method, the sampling method or gasoline.Correspondingly, measuring device 1 can relatively accurately be measured engine consumption.
In addition, measuring device 1 does not need as analysis by weight method and sampling method needed relative long measuring period (for example several hrs to tens hour).The waste gas of established amount is inhaled into the sulfur dioxide sound-pipe 22 in the measuring device 1, be used in the relatively short time (for example a few minutes are to dozens of minutes) measure engine consumption.
Measuring device 1 has the composition member of negligible amounts, and more traditional S tracking means has littler size.Particularly, measuring device 1 can be configured to as the size less than 1 cubic metre.Therefore, the transportation of device (this is comparatively difficult for traditional S tracking means) wants relatively easy.Correspondingly, for example in having the field of stationary engine, the use of measuring device 1 makes the measurement of carrying out engine consumption want relatively easy.Equally, for example under the situation of less relatively vehicle (as motorcycle), measuring device 1 can be installed in the vehicle, and in vehicle driving, measure engine consumption.
The more traditional S tracking means of measuring device 1 is relatively cheap.Measuring device 1 is consuming time at the measurement engine oil, does not need to be used to provide the gas generator of measuring required gas (as hydrogen).In addition, sulfur dioxide sound-pipe 22 is relatively cheap.Therefore, the use of measuring device 1 has reduced the investment of the equipment that is used to measure engine consumption.In addition, can reduce the operating cost of the measurement of engine consumption.
In addition, measuring device 1 has made things convenient for the replacing of chamber 15,18 and throttle mechanism 14.Therefore, if the composition member of measuring device 1 is stained by waste gas, chamber 15 grades can easily be changed.In other words, it is more convenient that measuring device 1 makes maintenance.
Consuming time when adopting measuring device 1 to measure engine oil, the amount of accurately measuring the waste gas that flows through sulfur dioxide sound-pipe 22 is very important.This is because come the calculation engine oil consumption based on the amount of the waste gas that flows through sulfur dioxide sound-pipe 22.Normally, the waste gas of motor 2 produces fluctuation.In other words, the flow velocity of motor 2 exhaust gas discharged is always inconstant.Therefore, if sulfur dioxide sound-pipe 22 is directly connected to motor 2, then may be difficult to accurately measure the amount of the waste gas that flows through sulfur dioxide sound-pipe 22 by flow integrator 30.Therefore, may be difficult to the accurate Calculation engine consumption.
On the other hand, changes in flow rate control mechanism 13 controls in the measured device 1 of the changes in flow rate of waste gas (for example fluctuation).Therefore, can relatively accurately measure the amount of the waste gas that flows through sulfur dioxide sound-pipe 22.Correspondingly, relatively accurately calculation engine oil consumption of measuring device 1.
From the angle that effective control flow rate changes, changes in flow rate control mechanism 13 preferably is arranged on the upstream of sulfur dioxide sound-pipe 22.Yet the setting of changes in flow rate control mechanism 13 is not limited to concrete position.For example, changes in flow rate control mechanism 13 can be arranged on the downstream of sulfur dioxide sound-pipe 22.
Changes in flow rate control mechanism 13 also is not limited to concrete structure.Yet as first embodiment, changes in flow rate control mechanism 13 preferably is built with throttle mechanism 14, chamber 15.Therefore, can save the cost of changes in flow rate control mechanism 13.In addition, make things convenient for the replacing of changes in flow rate control mechanism 13, thereby improved the convenience of its maintenance.
Preferably, under the state that motor 2 at full throttle rotates basically, measure the step of sulfur dioxide in the waste gas.This makes that the amount of the fuel to the air-fuel mixture of motor 2 is provided is relatively large.Therefore, can make the concentration of oxygen in the firing chamber of motor 2 relatively low.Thereby, prevented the interference gas nitrogen dioxide (NO of the sulfur dioxide sound-pipe 22 that its fundamental reaction mechanism is starch-iodine reaction
2) generation.Therefore, might measure the concentration of sulfur dioxide in the waste gas more accurately.
In the present embodiment, pipeline 10 and 12 is made by high thermal conductivity material.Particularly, pipeline 10 and 12 is made of copper.Therefore, the waste gas from motor 2 can be cooled off in pipeline 10 and 12 effectively.This can control the content of water in the waste gas.Condensed water is collected by chamber 15, thereby anti-sealing enters sulfur dioxide sound-pipe 22.In addition, because the chamber 15 among first embodiment is transparent, can observe condensed water.
In the present embodiment, in the measurement of motor 2 run durations that are provided general fuel (being reference fuel) and be provided between the measurement of motor 2 run durations of fuel combination and compare.In other words, between two kinds of operations, carried out measurement of comparison.Therefore, can reduce the influence of interference to the measurement generation of engine consumption.For example, as shown in Figure 6, water vapour and sulfur dioxide reaction in the waste gas, and the concentration of sulfur dioxide reduces usually when the temperature of waste gas reduces.Therefore, if the ambient temperature of measuring device 1 has departed from accounting temperature, will be tending towards taking place measurement error.For example, because the change of the ambient temperature between the measurement of carrying out in summer and winter may bring measurement error.Yet,,, can change the measurement error of bringing by ambient temperature and remain to minimum because carried out measurement of comparison between the operation of the operation of supply standard fuel and supplying mixed fuel according to present embodiment.This makes can measure engine consumption more accurately.
In the present embodiment, need before measuring engine consumption, not know clearly the ratio etc. of the Sulpher content in the engine oil.Therefore, under the situation of the unknown proportion of the Sulpher content in engine oil, the method for measurement of present embodiment has made things convenient for the measurement of engine consumption.
(second embodiment)
