摘要： This apparatus is applied to an engine equipped with a fuel supply system that supplies pressure-increased fuel to a fuel injection valve, and performs the fuel injection from the injection valve in one combustion cycle by a multiple injection process that includes a pre-injection and a main injection that are executed with an interval therebetween. The apparatus calculates a deviation between a required value (one-dot chain line) and an actual value (solid line) regarding the end timing of the pre-injection, based on the manner of fluctuation of the fuel pressure in the fuel injection that is detected by a pressure sensor. A target main injection timing and a target pre-interval are individually set on the basis of the state of operation of the engine. Based on the deviation, the target main injection timing and the target pre-interval, the apparatus sets control target values regarding the execution period of the pre-injection.

摘要： In order to estimate the cetane number of a fuel, fuel injection is executed by controlling the driving of a fuel injection valve by a prescribed amount. The amount of change in the rotation of a diesel engine generated in response to the fuel injection is detected, and the cetane number of the fuel is estimated on the basis of this amount of change in the rotation. The actual amount of fuel injected from the fuel injection valve is detected, and when the difference between the amount actually detected and the prescribed amount is equal to or greater than a threshold value, the execution of the fuel cetane number estimation process is restricted.

摘要： In one embodiment, a total pilot injection amount is calculated from the difference between a compressed gas temperature in a cylinder and a fuel self-ignition temperature. As pilot injection, a plurality of instances of divided pilot injection are performed, and by setting the injection amount per one instance of divided pilot injection to an injector minimum limit injection amount, each divided pilot injection amount is suppressed, and the penetration of fuel is suppressed to a low level so that attachment of fuel to a wall face is avoided, and also, fuel is caused to accumulate in the center portion of the cylinder.

摘要： In one embodiment, a total fuel injection amount is calculated from a torque required by an engine. A division ratio of a pre-injection amount that achieves both suppression of ignition delay of fuel from a main injection and suppression of a peak value of a heat production ratio of combustion from the main injection is calculated. Upper and lower limit guards are given to the obtained divided amount, and the divided injection amount is calculated. The injection amount of the main injection is obtained by subtracting the divided injection amount from the total fuel injection amount.
