Abstract: PROBLEM TO BE SOLVED: To detect a failure of a reforming-fuel injection valve for injecting fuel for reforming, in a system having a function for reforming fuel to be supplied to an engine.SOLUTION: In a reforming driving mode, a reforming driving is executed in which a reforming-fuel injection valve 26 injects the fuel for reforming into EGR gas while an EGR valve 25 is opened to recirculate a part of exhaust gas to an intake side as the EGR gas, and a fuel-reforming catalyst 28 reforms the fuel in the EGR gas into a highly combustive state. In the reforming driving mode (while the reforming-fuel injection valve 26 injects the fuel), an air-fuel ratio A/F detected by an air-fuel ratio sensor 21 is determined whether it is within a predetermined normal range (rich side threshold≤A/F≤lean side threshold), and if the air-fuel ratio A/F is determined to be out of the normal range (A/F

Abstract: PROBLEM TO BE SOLVED: To improve fuel reforming efficiency in a system having a function for reforming the fuel to be supplied to an engine.SOLUTION: An ECU 34 computes an injecting quantity of reforming-fuel which is injected by a reforming-fuel injecting valve 26 according to an engine driving condition (for example, engine rotation speed and engine load) and an EGR gas flow rate. The injecting quantity of the reforming-fuel is changed according to an EGR gas temperature or an alcohol concentration of the reforming-fuel, whereby temperatures of a fuel reforming catalyst 28 and the EGR gas are suppressed from decreasing due to a vaporization heat of the reforming-fuel. Further, an injecting time period of the reforming-fuel is changed according to the injecting quantity of the reinforming fuel and the EGR gas flow rate so that a maldistribution (unevenness) of the reforming-fuel, by which the reinforming fuel in the EGR gas flowing in the fuel reforming catalyst 28 becomes thick and thin, is suppressed. Furthermore, an injecting time period of the reforming-fuel is changed according to an engine rotation speed so that the reforming-fuel quantity for each cylinder is made substantially uniform.

Abstract: PROBLEM TO BE SOLVED: To effectively stabilize combustion state of self-ignited combustion of an internal combustion engine. SOLUTION: The control device causes fuel/air mixture to undergo self-igniting by compression in compression stroke to execute self-ignited combustion control, by controlling valve timing to provide a negative valve overlap period of time during which both of an exhaust valve and an intake valve become in a closed state, when an operating region of an internal combustion engine is at a predetermined self-ignited combustion region, executing in-cylinder injection for reforming that injects fuel into a cylinder during the negative valve overlap period of time, and executing port injection for output control that injects fuel to an intake port after execution of the in-cylinder injection for the reforming. The control device detects reforming degree of fuel injected by the in-cylinder injection for reforming, when the self-ignited combustion control is performed, predicts combustion state of the self-ignited combustion at the combustion cycle this time from fuel reforming degree detected at the combustion cycle this time, and corrects fuel injection amount of the port injection for output control at the combustion cycle this time depending on the prediction result, thus stabilizing combustion state of the self-ignited combustion.

Abstract: PROBLEM TO BE SOLVED: To prevent wrong diagnosis of leak due to opening of a fuel filler cap of a fuel tank, when leak diagnosis of an evaporated gas purge system is performed during engine stop.
SOLUTION: Fuel remaining quantity is detected while an ignition switch is off (engine stop), and then leak diagnosis is started and existence of leak is provisionally judged, and diagnosis result is stored in a back up RAM or the like (steps 101-105). Fuel remaining quantity is detected while the ignition switch is on (engine start), fuel remaining quantity at the time of engine start and fuel remaining quantity at the time of previous engine stop are compared and it is judged whether the fuel filler cap is opened during engine stop (steps 106-108). Leak diagnosis result is made void if the fuel filler cap is opened during engine stop, and the leak diagnosis result is settled as the final leak diagnosis result as it is (steps 109-110) if the fuel filler cap is not opened.

Abstract: PROBLEM TO BE SOLVED: To provide a system for controlling the power generation of an internal combustion engine in which, while securing a necessary electrical output, the electrical output is so controlled that the discharge of NO x from the internal combustion engine does not exceed an occlusion capacity of an NO x catalyst. SOLUTION: During the operation of the engine, the amount of NO x storage in the NO x catalyst is computed at a specified cycle, and an NO x discharge guard is corrected in accordance with the amount of NO x occlusion. Thus, while securing a necessary electrical output, the electrical output is controlled so that the NO x discharge from the engine does not exceed the occlusion capacity of the NO x catalyst. Further, during the engine operation, an increment of NO x discharge per unit electrical output is computed at the specified cycle. If the increment of the NO x discharge per unit electrical output is an almost specified value, the electrical output is increased by generating power by an upper limit guard set for power generation torque variation in accordance with a guard for the NO x -discharge. If the increment of the NO x discharge per unit electrical output exceeds a specified value, the increment of the NO x discharge per unit electrical output is decreased by generating power by a lower limit guard set for power generation torque variation.

Abstract: PROBLEM TO BE SOLVED: To reduce increase of amount of exhaust gas toxic component exhaust by power generation of a power generator of a vehicle. SOLUTION: Amount of increase CEM of amount of toxic component exhaust per unit power generation amount of the power generator is calculated by the following expression and a condition for reducing the amount of increase CEM of the amount of toxic component exhaust is selected for power generation during engine operation. CEM=(amount of toxic component exhaust at power generation time - amount of toxic component exhaust at non-power generation time)/amount of power generation, wherein the amount of toxic component exhaust at power generation time is amount of exhaust of exhaust gas toxic component when generating power by the power generator during engine operation and the amount of toxic component exhaust at non-power generation time is amount of exhaust of exhaust gas toxic component when stopping power generation by the power generator. If there is possibility of insufficient charging of a battery, power generation by the power generator is performed with priority to restore a battery charging ratio SOC even under an operation condition for increasing the amount of increase CEM of the amount of toxic component exhaust per unit power generation amount slightly.

Abstract: PROBLEM TO BE SOLVED: To prevent the misdiagnosis of the leakage caused by the deformation of a fuel tank generated by pressure difference of the inside and outside of the fuel tank, in the leakage diagnosis in an evaporated gas purging system having the fuel tank made out of a resin.
SOLUTION: An atmospheric air switch valve and a purge control valve are closed to start the leakage diagnosis in a state of applying a sealed condition to an evaporation system, when an engine is stopped and the leakage diagnosis execution condition is established. The presence or absence of the leakage is determined by comparing the tank internal pressure Pt with a determination value during the leakage diagnosis. Whether the fuel tank is deformed or not is determined on the basis of whether the tank internal pressure Pt is suddenly changed or not during the leakage diagnosis, and the leakage diagnosis is stopped when the deformation of the fuel tank (sudden change of tank internal pressure Pt) is generated. Whereby the misdiagnosis of the presence or absence of the leakage caused by the change of the pressure by the deformation of the fuel tank can be prevented. The atmospheric air switch valve is opened to release the sealed state of the evaporation system during the stop of the leakage diagnosis.
