  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  A water jacket (not shown) is formed in an internal combustion engine (hereinafter referred to as an engine) 10 provided with the lubricating device 1. The jacket inlet 12 and jacket outlet 14 of the water jacket are connected to each other by a cooling water passage 16 and a radiator 20 cooled by an electric fan 18 to form a cooling water circulation passage. A water pump 22 is provided on the jacket inlet 12 side. During operation of the engine 10, the cooling water is pumped by the water pump 22, circulates in the water jacket, cools the engine 10, circulates in the cooling water passage 16 and the radiator 20, dissipates heat, and is introduced into the water jacket again. Has been. The cooling water is also supplied to the oil cooler 24 of the lubricating device 1 to cool the engine oil.

  The lubrication apparatus 1 is provided with an oil pump 26. The suction side of the oil pump 26 is connected to a strainer 28. The discharge side of the oil pump 26 is connected to an oil passage 34 formed in the engine 10 through an oil filter 32 in addition to a relief valve 30.

  More specifically, the lubricating device 1 includes an oil pan 36 as an oil reservoir, and engine oil supplied to the oil passage 34 is stored in the oil pan 36. The engine oil is sucked from the oil pan 36 through the strainer 28 by the oil pump 26 and is pumped to the oil filter 32.

  A main passage 38 is formed on the downstream side of the oil filter 32 so that engine oil from the oil filter 32 is supplied to the oil passage 34 via the oil cooler 24. The main passage 38 is formed with a first oil passage 40 and a second oil passage 42 that branch from the main passage 38 and return to the main passage 38. The first oil passage 40 branches from the upstream main passage 38a of the main passage 38 that extends upstream from the oil cooler 24 between the oil filter 32 and the oil cooler 24, and joins the upstream main passage 38a. It extends. The second oil passage 42 branches from the downstream main passage 38b of the main passage 38 that extends downstream from the oil cooler 24 and extends so as to join the downstream main passage 38b. Accordingly, oil that has been sucked from the oil pan 36 and has not passed through the oil cooler 24 (hereinafter, may be referred to as first oil) can flow into the first oil passage 40, and can flow into the second oil passage 42. Oil that has been sucked from the oil pan 36 and then passed through the oil cooler 24 (hereinafter, may be referred to as second oil) can flow. Each of the first oil passage 40 and the second oil passage 42 is formed so as to extend into the removing device 44.

  In order to adjust the flow of oil to the first oil passage 40, that is, to adjust the supply amount of the first oil to the removal device 44, the first oil passage 40 that extends toward the removal device 44 has a first A first valve 46, which is a control valve here, is provided in the oil supply passage 40a. Further, in order to adjust the flow of oil to the second oil passage 42, that is, to adjust the supply amount of the second oil to the removal device 44, the second oil passage 42 extending toward the removal device 44 The second oil supply passage 42a is provided with a second valve 48, which is a control valve here. The first valve 46, the second valve 48, and a part of an ECU (to be described later) having a function of control means for controlling the operation of the first valve 46, the second valve 48, supply the first oil and the second oil to the removing device 44 It is contained in the supply apparatus 49 comprised so that.

  The main passage 38 is connected to the oil passage 34 via a regulator valve 50 for adjusting hydraulic pressure. Thus, the engine oil during operation of the engine 10 is sucked up by the oil pump 26 through the strainer 28 and reaches the oil filter 32 and the oil cooler 24. A part of the engine oil flows into the oil passage 34 after flowing into the first oil passage 40 and the second oil passage 42 by the operation of the first valve 46 and the second valve 48. The oil that has reached the oil passage 34 lubricates a piston, a journal, and the like (not shown) in the engine 10 and then returns to the oil pan 36. For example, the oil pumped to the cylinder head passes through an oil drop passage (oil return hole) (not shown) that is formed in the cylinder block and the cylinder head and communicates between the head cover and the crankcase, that is, the oil pan 36. Returned to the oil pan 36. More specifically, such an oil dropping passage is a passage for dropping (returning) oil that has finished lubrication of the valve system from the cylinder head into the oil pan, and at the same time, blow-by in the crankcase. This is a passage for ascending and moving the gas into the head cover.

  Here, the blow-by gas is a gas that leaks into the crankcase from the gap between the piston ring of the piston and the cylinder bore of the cylinder block. This blow-by gas may contain a large amount of hydrocarbons and moisture. For this reason, too much blow-by gas causes premature deterioration of engine oil and rust inside the engine. Further, since the blow-by gas contains hydrocarbons, it is not environmentally preferable to release it to the atmosphere as it is. Therefore, the engine 10 includes a known blow-by gas recirculation device (not shown). As described above, the blow-by gas is moved upward from the crankcase into the head cover through the oil dropping passage. After the blow-by gas is introduced into the head cover, the blow-in gas is forcibly returned to the intake passage through the PCV passage of the blow-by gas recirculation device using the intake negative pressure and supplied to the combustion chamber.

  An oil separator chamber for separating oil from blow-by gas is defined in the head cover of the engine 10. The blow-by gas includes oil mist as a gas generated by stirring and evaporation of oil in the crankcase in addition to the above-described hydrocarbons and moisture as fuel components. For this reason, if the blow-by gas is simply circulated to the intake side, the oil is also burned at the same time, which increases the amount of oil consumed and causes white smoke due to oil combustion. Therefore, an oil separator chamber having a known configuration is formed in the head cover. The oil separator chamber is, for example, partly or entirely defined by a baffle plate. By passing the blow-by gas through the oil separator chamber, it is possible to separate and recover the oil from the blow-by gas before returning the blow-by gas to the intake system, and to solve such problems. The oil separator chamber can be provided at a place other than the head cover.

  By the way, such blow-by gas contains NOx and moisture contained in the already burned gas. Since the head cover is difficult to transmit heat from the engine and its outer surface is exposed to the outside air and cooled by cooling air or the like, condensed water due to condensation or the like tends to be generated on the inner surface of the head cover. Therefore, an acidic substance such as nitric acid is easily formed in the head cover due to the reaction thereof. Such acidic substances can be mixed with lubricating oil, that is, engine oil, and can promote generation, adhesion, and accumulation of sludge inside the engine.

  Therefore, the lubricating device 1 includes the removing device 44 in order to remove such acidic substances, that is, acidic components from the oil. The removing device 44 includes a case member 44c and an ion exchange resin put in the case member 44c. The removal device 44 is positioned in the crankcase here, but may be positioned at various locations inside and outside the engine 10.

  The case member 44c is configured to form a first chamber 44a and a second chamber 44b separated from each other inside the removing device 44. Although not shown, the first chamber 44a and the second chamber 44b are configured to be able to transfer heat to each other. For example, a heat transfer member such as a fin is provided in the partition 44d between the first chamber 44a and the second chamber 44b. Is provided. The first chamber 44a and the second chamber 44b are separated by a partition 44d so that oil does not flow into each other. The first chamber 44a is positioned in the middle of the first oil passage 40 so that the first oil can enter and exit, and the second chamber 44b is positioned in the middle of the second oil passage 42 so that the second oil can enter and exit. Yes. Here, the first chamber 44 a may be included in the first oil passage 40, and the second chamber 44 b may be included in the second oil passage 42. The same kind of ion exchange resin is disposed in each of the first chamber 44a and the second chamber 44b. Here, each of the first chamber 44a and the second chamber 44b is provided with a wire mesh member so that the ion exchange resin does not flow out of the first chamber 44a and the second chamber 44b.

  The ion exchange resin of the removing device 44 is a reactant and has a function of adsorbing predetermined ions (ion components). In other words, in order to remove predetermined ions, the ion exchange resin of the removing device 44 has a function of adsorbing such predetermined ions. Note that the ion exchange resin has a function of adsorbing predetermined ions and releasing other ions instead. Here, an anionic ion exchange resin is used as the ion exchange resin, and the ion exchange resin of the removing device 44 is made of this. Examples of ion exchange resins include Diaion (registered trademark) series ion exchange resins manufactured by Mitsubishi Chemical Corporation and Amberlite (registered trademark) series ion exchange resins manufactured by Rohm and Haas.

Here, specifically, an anionic ion exchange resin having a function of adsorbing nitrate ions is used to remove nitrate ions (NO ₃ ⁻ ) that can be generated by NOx and water in blow-by gas from the oil. It is done. Such an anionic ion exchange resin has a function of adsorbing its anions and, for example, releasing hydroxide ions instead. Such an ion exchange resin may have various shapes such as a fiber shape, a bead shape (spherical shape), or a membrane shape.

  The engine 10 includes an ECU 54 having functions of various control means or control devices. The ECU 54 is provided with an input / output device (not shown), a storage device (ROM, RAM, nonvolatile RAM, etc.) incorporating a number of control programs, a CPU, a timer counter, and the like. The ECU 54 performs comprehensive control of the engine 10 including oil supply control to the removing device 44.

  Various sensors and the like are connected to the ECU 54. For example, a detection signal is output from the first temperature sensor (first temperature detecting means) 56 to the ECU 54 in order to detect the temperature of the first oil. Further, a detection signal is output from the second temperature sensor (second temperature detecting means) 58 to the ECU 54 in order to detect the temperature of the second oil. Although not shown, the ECU 54 outputs a detection signal from the engine rotation speed sensor to detect the engine rotation speed, and outputs a detection signal from the engine load sensor to detect the engine load.

  The ECU 54 controls the operation of the first valve 46 and the second valve 48 based on output signals from the various sensors and the like, particularly based on output signals from the first temperature sensor 56 and the second temperature sensor 58. That is, the ECU 54 can control the supply amount of the first oil and the supply amount of the second oil to the removing device 44 according to the temperatures of both the first oil and the second oil. Each of the first valve 46 and the second valve 48 is closed in the initial state.

  The operation control of the first valve 46 and the second valve 48 will be described with reference to FIG. FIG. 2 conceptually shows the relationship between the temperature T of the ion exchange resin of the removing device 44 and the ion adsorption efficiency η of the ion exchange resin. The ion exchange resin has a tolerable temperature Tmax, and when the temperature is within a predetermined temperature range, its function, particularly the adsorption function, is suitably exhibited. Such a predetermined temperature range of the ion exchange resin is a temperature range of the first temperature T1 or more and the second temperature T2 or less. Here, the temperature range in which the ion exchange resin sufficiently exhibits its adsorption function, specifically, the temperature range in which the adsorption efficiency equal to or higher than the predetermined adsorption efficiency η1 is defined as the predetermined temperature range. That is, the predetermined temperature range is set in consideration of the temperature characteristics of the ion exchange resin. The predetermined adsorption efficiency η1 can be set in various ways, for example, 90% of the maximum adsorption efficiency ηmax. Preferably, the predetermined temperature range is a temperature range in which the ion exchange resin of the removing device 44 exhibits an adsorption efficiency of 70% or more with respect to the maximum adsorption efficiency ηmax.

    The ECU 54 increases the temperature T of the ion exchange resin of the removing device 44 to the predetermined temperature range and maintains it there, that is, adjust the temperature T of the ion exchange resin, as described below. The operation of the first valve 46 and the second valve 48 is controlled.

  The ECU 54 opens the first valve 46 when the temperature Toil1 of the first oil is not less than the first temperature T1 and not more than the second temperature T2 and the temperature Toil2 of the second oil is less than the temperature Toil1 of the first oil, An operation signal is output so as to close the second valve 48. Specifically, the ECU 54 outputs an operation signal for operating the actuator of the first valve 46 so as to open the first valve 46, and the actuator of the second valve 48 so as to close the second valve 48. The operation signal for operating is output.

  Further, when the temperature Toil2 of the second oil is equal to or higher than the first temperature T1 and lower than the second temperature T2, and the temperature Toil1 of the first oil is higher than the second temperature T2, the ECU 54 The operation of the valves 46 and 48 is controlled in accordance with the relationship between the temperature Toil1 of one oil and the temperature Toil2 of the second oil. The ECU 54 uses the data determined in advance through experiments and a predetermined arithmetic expression, so that the relationship between the temperature Toil1 of the first oil and the temperature Toil2 of the second oil indicates that the temperature of the ion exchange resin is the first temperature T1. When it is determined that the relationship can be maintained at the second temperature T2 or lower, an operation signal is output to open the first valve 46 and the second valve 48. On the other hand, the ECU 54 uses the data determined in advance through experiments and a predetermined arithmetic expression to determine that the relationship between the temperature Toil1 of the first oil and the temperature Toil2 of the second oil is the second temperature of the ion exchange resin. When it is determined that the relationship may increase to the temperature T2 or higher, an operation signal is output so that the first valve 46 is closed and the second valve 48 is opened.

  Thus, the ECU 54 controls the operation of the first valve 46 and the second valve 48 according to the temperature of the first oil that has not yet passed through the oil cooler 24 and the temperature of the second oil that has passed through the oil cooler 24. The supply of the first oil and the second oil to the removing device 44 is controlled. Thereby, the temperature of the ion exchange resin of the removing device 44 is adjusted, and can be raised to the predetermined temperature range and maintained in that temperature range. Therefore, the above-mentioned predetermined component can be more appropriately removed from the oil by the removing device 44, and deterioration of the oil can be suppressed.

  In addition, particularly when the engine is cold started, it is required to warm up the ion exchange resin. In such a case, as described below, the operation of the first valve 46 and the second valve 48 is controlled so that one oil having a relatively high temperature is used, so that the ion exchange resin in the removing device 44 is warmed up. (Prompted to raise and maintain the temperature of the ion exchange resin in the predetermined temperature range). Specifically, when the temperature of one of the first oil and the second oil is equal to or higher than a third temperature T3 corresponding to an ion adsorption efficiency η3 of 25%, for example, and lower than the first temperature T1, the valve 46, as follows: By controlling 48, the ion exchange resin is warmed up. For example, the temperature of the engine oil is generally lower than the temperature of the cooling water, the temperature Toil1 of the first oil is lower than the third temperature T3, the temperature Toil2 of the second oil is equal to or higher than the third temperature T3 and lower than the first temperature T1. When the first valve 46 is closed, the second valve 48 is opened. On the other hand, when the temperature Toil2 of the second oil is lower than the third temperature T3 and the temperature Toil1 of the first oil is equal to or higher than the third temperature T3 and lower than the first temperature T1, the first valve 46 is opened, The two valve 48 is closed.

  However, the first valve 46 and the second valve 48 are positively closed when the temperature of the engine oil is in a temperature range that obstructs the removal of a predetermined component in the oil by the removing device 44. Specifically, when both the first oil temperature and the second oil temperature are lower than the third temperature T3, the ECU 54 positively outputs an operation signal so as to close both the first valve 46 and the second valve 48. . This is because, when such oil is supplied to the removing device 44, the ion exchange resin is cooled, and there is a possibility that the temperature of the ion exchange resin is raised and maintained in the predetermined temperature range. When both the first oil temperature and the second oil temperature exceed the second temperature T2, the ECU 54 positively outputs an operation signal so as to close both the first valve 46 and the second valve 48. To do. This is because when such oil is supplied to the removal device 44, the ion exchange resin is overheated, and there is a possibility that the temperature of the ion exchange resin is raised to the service temperature Tmax or higher.

  While the present invention has been described based on one embodiment, various changes can be made. The supply timing and supply timing of the first oil to the removal device and the supply timing and supply timing of the second oil to the removal device are not limited to the above description, and the temperature of the ion exchange resin of the removal device is the predetermined temperature. It can be varied to keep up there. For example, in the said embodiment, although the 1st valve and the 2nd valve were simply opened and closed, it is also possible to open to intermediate opening other than full open and full close.

  Further, for example, the temperature of the first oil and the temperature of the second oil can be estimated based on the engine load or the engine operating state without using the temperature sensor. In the above embodiment, the supply amount of the first oil and the supply amount of the second oil to the removing device are controlled according to the temperature of the first oil and the temperature of the second oil. Since the oil temperature is related, oil supply control to the removing device may be executed according to one of these temperatures.

  Further, in the above embodiment, the first oil and the second oil are separately supplied to the removing device, and they are not mixed when supplied to the removing device, but they are mixed when supplied to the removing device. May be enabled. This is because by mixing oils having different temperatures, the temperature of the oil in the removing device can be adjusted, and the temperature of the ion exchange resin in the removing device can be raised and maintained in the predetermined temperature range as in the above embodiment. . For example, the partitioning portion 44d of the removal device can be omitted, and in this case, the passage for discharging oil from the removal device can be integrated. Further, the first oil supply passage 40a and the second oil supply passage 42a may be configured to merge.

  Further, the oil supply control to the removing device 44 as described above may be performed periodically for a predetermined time every time the travel distance of the vehicle including the engine 10 reaches a predetermined distance. For example, such supply control can be executed every time the travel distance reaches 3000 km.

  Moreover, in the said embodiment, although the 1st valve and the 2nd valve were control valves controlled by a control means, they may be other types of valves. For example, each of the first valve and the second valve may be a valve that automatically operates according to the temperature of the oil.

  In addition, a reactant such as an ion exchange resin provided in the removing device has a high temperature within a temperature range where the reactant exhibits its function with high efficiency and a temperature range Toil (see FIG. 2) of the engine oil of the engine. It is good to select so that a field (for example, 80 ° C-100 ° C) may coincide or overlap.

  Furthermore, although the anionic ion exchange resin is used as the reactant in the lubrication apparatus of the above embodiment, the reactant is not limited to the ion exchange resin as described above. Various anionic ion exchange resins and / or cationic ion exchange resins can be used as the reactant. This will be specifically described below.

Ions that are desired to be adsorbed and removed by using an anionic ion exchange resin include not only nitrate ions (NO ₃ ⁻ ) but also sulfate ions (SO ₄ ²⁻ ) that can be generated from blow-by gas, blow-by gas, and the like. There are acetate ions (CH ₃ COO ⁻ ) that can be generated, as well as formate ions (HCOO ⁻ ), chloride ions (Cl ⁻ ), and chromate ions (CrO ₄ ²⁻ ) that can be generated from blow-by gas. An anionic ion exchange resin having a function of adsorbing at least one ion selected from a group containing these or a group consisting of these may be used. The ions released from the anionic ion exchange resin may be ions that do not promote the deterioration of the oil, and preferably ions that suppress the deterioration of the oil.

  In addition, when an alkaline substance such as calcium carbonate is provided in the engine so as to suppress sludge generation, an ion exchange resin having a function of adsorbing Ca ions may be used. In addition, when calcium sulfonate is added as an additive in the oil, Ca ions can be generated from this calcium sulfonate. In such a case, a cationic ion exchange resin having a function of adsorbing Ca ions is also provided. It should be used.

In addition, not only such Ca ions (Ca ²⁺ ) but also, for example, Al ³⁺ , Fe ²⁺ , Fe ³⁺ , Cr are ions desired to be adsorbed and removed by using a cationic ion exchange resin. ^{There are 3+} , Pb ²⁺ , Ni ²⁺ , Cu ²⁺ , Mg ²⁺ and Ti ⁺ . These can come from additives to the oil, such as ZnDTP, or from wear and / or elution of engine components. In particular, it is desired that Cu ions, Al ions, Fe ions, and the like generated in engine oil due to wear of the sliding portion of the engine be removed. A cationic ion exchange resin having a function of adsorbing at least one ion selected from the group containing these or a group consisting of these may be used. The ions released from the cationic ion exchange resin may be ions that do not promote the deterioration of the oil, and preferably ions that suppress the deterioration of the oil.

  The reactant in the present invention is not limited to an ion exchange resin. Ion exchange resins, inorganic ion exchangers, chelate resins and / or synthetic adsorbents can be used as reactants. As the reactant, various substances having a function of adsorbing a predetermined component, and various substances having a function of adsorbing a predetermined component and a function of releasing another predetermined component can be used.

  Further, the components to be adsorbed and removed by the reactants are acid components such as nitrate ions, components generated from additives, components generated by wear and / or elution of engine components, and oil It may be an unnecessary component or impurity therein. In addition, the component which should be adsorb | sucked is not limited to the said ion, Moreover, components other than ion can also be included. The component to be released from the reactant is preferably a component that is harmless to engine oil or a useful component that functions as an additive to the oil. Similarly, the component to be released is not limited to the above ions, and may include components other than ions.

  Further, in the removing device, a wire mesh case, a punching mesh type case, a bag-like case formed using a wire mesh, resin, or the like, or a mesh type cylindrical case (having a storage area between the inner cylinder and the outer cylinder). ) And the like, in which a reactant such as an ion exchange resin can be placed. Further, the reactant can be laminated on a plate or a film, or can be applied to a part by using a spray or the like, and the reactant fixed on the plate or the like can be provided in the removing device. .

  As described above, the present invention has been described based on the above embodiments and modifications. In these embodiments, an ion exchange resin is basically used as the reactant. Various experiments were conducted in order to investigate the effects of arranging the ion exchange resin in the oil circulation path as described above. For example, when an ion exchange resin having a function of adsorbing nitrate ions is added to oil containing nitric acid and the oil is heated to a predetermined temperature, the viscosity of the oil increases. However, the amount of increase was about half of the amount of increase in oil viscosity when no such ion exchange resin was added. This means that nitrate ions were adsorbed by the ion exchange resin and sludge generation was suppressed. Thus, the deterioration of the oil could be suppressed by using the ion exchange resin having a function of adsorbing nitrate ions. Therefore, it is obvious that the deterioration of the engine oil can be suppressed by the lubricating device of the above-described embodiment.

  As described above, the present invention has been described based on the above embodiment and its modifications. However, the present invention is not limited to these embodiments and the like, and still allows other embodiments. The present invention includes all modifications, applications, and equivalents included in the spirit of the present invention defined by the claims.
