摘要： PROBLEM TO BE SOLVED: To restrain a clogging of a cooling device due to particulates or the like in a constitution of a device provided with a recirculation passage for recirculating a part of an exhaust gas of an internal combustion engine to an intake passage, and the cooling device provided to a midway of the recirculation passage.
SOLUTION: This exhaust recirculation device of the internal combustion engine is constituted such that, in the recirculation passage (EGR passage) 30 of an engine 1, an electric heater 31, a particulate filter 32, an EGE cooler 33, an EGR valve 34 are sequentially arranged to an upstream side to a downstream side along a flowing direction of a gas (EGR gas) flowing in the recirculation passage 30. An electric control unit 20 switches an energizing state (ON/OFF) of the electric heater 31 based on a temperature of a downstream side of the particulate filter 32 of the EGR passage 30. Accordingly, even under a condition in which a temperature of an exhaust gas (EGR gas) flowing in the EGR passage 30 is low, the particulate filter 32 can efficiently function without clogging of the particulate filter 32.

摘要： PROBLEM TO BE SOLVED: To effectively suppress deterioration of emission and fuel economy due to effect of exhaust valve opening timing during acceleration in a control device for an internal combustion engine.
SOLUTION: An upper limit value of a fuel injection amount is set based on the exhaust valve opening timing of the internal combustion engine. When increasing the fuel injection amount during acceleration, the fuel injection amount is restricted to the upper limit value or less. The exhaust valve opening timing wherein the upper limit value of the injection amount is the maximum is comparatively early in a low speed area. The timing moves toward a delaying direction as the engine speed rises from that point toward an intermediate speed area, and moves toward an earlier direction as the engine speed rises from that point to a high speed area.

摘要： PROBLEM TO BE SOLVED: To simultaneously satisfy an internal EGR quantity increase request and an exhaust temperature rise request for reducing an NOx emission, by eliminating wastefulness and a shortage, when performing early closing control of an exhaust valve and delay opening control of an intake valve, in a control device of an internal combustion engine.
SOLUTION: This control device has an exhaust variable valve train 70 capable of changing the closing timing of the exhaust valve 68, and has an intake variable valve train 66 capable of adjusting the opening timing of the intake valve 64. When making a temperature rise request for exhaust gas, an ignition timing advance quantity (EX early closing X) of the closing timing of the exhaust valve to a top dead center is determined based on an internal EGR gas quantity required for restraining the NOx emission in a specific value or less. IN delay opening Y is determined so that an ignition timing delay quantity (IN delay opening Y) of the opening timing of the intake valve to the top dead center is set to the same quantity or more as the EX early opening X and a difference of subtracting the EX early closing X from the IN delay opening Y becomes the size corresponding to the closing timing of the exhaust valve.

摘要： PROBLEM TO BE SOLVED: To provide a technique of protecting an intake system engine member such as compressor from excessive temperature rise and suitably inhibiting generation amounts of NOx and smoke in a situation that temperature of exhaust gas becomes high.
SOLUTION: An EGR system comprises a low-pressure EGR passage connecting an exhaust passage downstream of a turbine and an intake passage upstream of the compressor. When the temperature of exhaust gas recirculated to an internal combustion engine through the low-pressure EGR passage exceeds a predetermined reference temperature, a quantity of low-pressure EGR gas is corrected for reduction by decreasing an opening of a low-pressure EGR valve (S305, S306) and an effective compression ratio of cylinders of the internal combustion engine is lowered by advancing or retarding a valve close timing of an intake valve in an intake stroke based on a reduction correction quantity of the low-pressure EGR gas (S307). A quantity of the low-pressure EGR gas flowing into an intake system is reduced and therefore excessive temperature rise of the intake system is inhibited. Cylinder temperature is lowered and therefore increase of the NOx generation amount due to insufficiency of EGR can be avoided.

摘要： PROBLEM TO BE SOLVED: To provide excellent drivability, by effectively restraining an increase in vehicle inside noise, in transitional operation, in a control device of an internal combustion engine.
SOLUTION: When discriminated as being in an unsteady state, that is, a transitional operation state (Step 100), next, whether or not to be in a low speed gear stage is discriminated (Step 102). When put in the low speed gear stage, and an occupant easily feels an increase in combustion noise, and can also determinate that an allowance of driving force is large. Then, in this case, a transitional correction (for example, a quantity increase in internal EGR) is made in the direction for restraining the combustion noise (Step 104). While, when put in a high sped gear stage, an allowance of the driving force is reduced, and a determination can also be made that the occupant hardly feels even if the combustion noise increases a little. Then, in this case, the transitional correction (for example, an increase in the swirl ratio) is made in the direction for stabilizing combustion (Step 106).

摘要： PROBLEM TO BE SOLVED: To accurately detect fuel properties through a simple structure in a control unit of an internal combustion engine. SOLUTION: Whether a condition where cetane value of fuel is detectable is established or not is determined (step 100). When establishment of the condition is determined, control is performed to set the closing timing of an intake valve 52 later than usual (step 102). The magnitude of engine rotation fluctuation is successively detected (step 104). A cetane value is calculated based on the detected magnitude of engine rotation fluctuation (step 106). According to the above processing, since the actual compression ratio is reduced by delaying the closing of the intake valve 52, the temperature and pressure at about the compression top dead center are reduced. Therefore, the influence of fuel of low cetane value on engine rotation fluctuation can be amplified. Consequently, the cetane value can be accurately detected. COPYRIGHT: (C)2008,JPO&INPIT
