摘要： PROBLEM TO BE SOLVED: To enhance a deposit separating effect so as to prevent deterioration of performance of an internal combustion engine caused by an increase of a deposit accumulation amount, in a certain period of time immediately after changing from fuel injection by only an intake passage injection injector to fuel injection by a cylinder injection injector. SOLUTION: A cylinder injection condition setting section 530 sets conditions for fuel injection from the cylinder injection injector. The cylinder injection condition setting section 530 includes a normal condition setting part 532 and a deposit separating condition setting part 534. The deposit separating condition setting part 534 compares with the fuel injection conditions set by the normal condition setting part 532 and sets fuel injection conditions which are more effective in separating the deposit of the cylinder injection injector in an initial period from the point of changing from a PFI mode in which the cylinder injection is stopped to a cylinder injection mode. More specifically, as compared with the normal time fuel injection conditions, at least one of steps of raising the fuel injection pressure and increasing the number of times of fuel injection per cycle is performed.

摘要： PROBLEM TO BE SOLVED: To correct injection amount under a general engine operating condition without creating a special operating condition, in an internal combustion engine in which a plurality of fuel injection valves are provided per cylinder. SOLUTION: In the engine 11, the plurality of fuel injection valves INJ(1), INJ(2) are provided per cylinder, and the fuel injection valves INJ(1), INJ(2) corresponding to an injection valve operating range which is switched in accordance with the operating condition serve as fuel injection valves related to injection. An electronic control device 51 calculates a correction value to compensate for a difference between required injection amount and actual injection amount corresponding to the operating condition of the engine 11, and reflects the correction value in fuel injection control. In calculating the correction value, every time the injection valve operating range is switched to a single injection valve operating range for injecting fuel by the single fuel injection valve INJ(1) or INJ(2) in accordance with the operating condition of the engine 11, the electronic control device 51 calculates the correction value regarding the fuel injection valve INJ(1) or INJ(2).

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection controller for an internal combustion engine capable of satisfactorily suppressing fuel leakage from an injector, in particular, an injector for injection in a cylinder.
SOLUTION: Fuel pressure in a fuel pipe of the injector for injection in the cylinder in an idle operation region is monitored to perform fuel injection by the injector for injection in the cylinder forcedly when fuel pressure exceeds a first predetermined value at which it becomes excessive as remaining pressure after the engine stops (there is remaining pressure). At this time, when fuel pressure to be monitored exceeds the first predetermined value and is below a second predetermined value at which assist injection by an injector for intake port injection is required in an engine operation condition, assist injection by the injector for intake port injection is performed together with forced fuel injection by the injector for injection in the cylinder (step S104). When fuel pressure to be monitored exceeds the second predetermined value and becomes a high value, only fuel injection by the injector for injection in the cylinder is performed (step S105).

摘要： PROBLEM TO BE SOLVED: To provide a control device of a cylinder injection internal combustion engine for maintaining a superior combustion state regardless of a change in cylinder air current strength caused by a change with the lapse of time of deposition of an intake air deposit. SOLUTION: An electronic control device 20 estimates a change in the tumble ratio by a change with the lapse of time of the deposition of the intake air deposit on the basis of a change in the combustion gas temperature detected by an exhaust temperature sensor 21, and delayably corrects the fuel injection timing in stratified combustion operation when the estimated tumble ratio increases. Thus, fuel is injected in the sufficiently weakened timing of a residual air current regardless of a change in the residual air current in a compression stroke caused by an increase in the tumble ratio, and since excessive agitation of the fuel caused by an increase in the tumble ratio is restrained, a layer of a variable thick air-fuel mixture can be stably formed in the vicinity of a spark plug 17.

摘要： PROBLEM TO BE SOLVED: To provide a controller for an internal combustion engine provided with a variable valve mechanism, capable of precisely determining whether knocking occurs or not.
SOLUTION: The controller is applied to the internal combustion engine having a plurality of cylinders, and determines the occurrence of knocking based on an output signal of a knocking sensor in a knocking determination period, controls operation of the variable valve mechanism (an intake valve timing alternation mechanism and a working angle alternation mechanism) and controls operation of an injector. The controller controls the engine so that only one of noise (circle A) caused by closing of an intake valve and noise (circle B and circle C) caused by operation of the injector is overlapped with the output signal of the knocking sensor in the knocking determination period (in a period in which a gate signal is operated to be ON).
