Abstract: An electronic control unit detects a manner of fluctuation of a fuel pressure with injection of fuel by a fuel injection valve with the use of a fuel pressure sensor, and calculates a tendency of deviation of an actual fuel injection characteristic of the fuel injection valve with respect to a basic fuel injection characteristic on the basis of a result of comparison between a detected temporal waveform and a basic temporal waveform. The tendency of deviation is reflected at a predetermined reflection rate (R) at the time of updating a learned value (Gij) for compensating for an individual difference of the fuel injection valve. The predetermined reflection rate (R) is increased when an accumulated value (D) of a vehicle travel distance is shorter than a predetermined value (Dth) as compared with when the accumulated value (D) is longer than or equal to the predetermined value (Dth).

Abstract: A microcomputer determines that an abnormality has occurred in calculation functions regarding calculation of an injection amount command value and the like, based on a deviation of the injection amount command value, in an increasing manner, from a monitoring injection amount. The microcomputer calculates, based on a cooling fluid temperature of an engine, a start-up injection amount such that the start-up injection amount becomes smaller when the cooling fluid temperature is high than when the cooling fluid temperature is low, and uses the start-up injection amount as the injection amount command value immediately after the completion of start-up of the engine. Besides, the microcomputer uses the smaller one of a start-up injection amount calculated this time and a monitoring start-up injection amount calculated last time, as a monitoring start-up injection amount that is used as the aforementioned monitoring injection amount immediately after the completion of start-up of the engine.

Abstract: A microcomputer determines a presence of an abnormality of a fuel injection quantity control device based on a comparison between a required injection quantity as a command value for the amount of a fuel injected from an injector in one engine cycle and a total monitor injection quantity as a total value of monitor injection quantities obtained from an energization time monitor value of the injector for each fuel injection in the one engine cycle. The microcomputer removes a micro-injection correction amount from the monitor injection quantity when the monitor injection quantity is below a determination value and executes a removal processing in which the removal of the micro-injection correction amount from the monitor injection quantity is not performed when the monitor injection quantity is at least the determination value. The total value of the monitor injection quantities after the removal processing is regarded as the total monitor injection quantity.

Abstract: A control apparatus for an engine includes a control unit. The engine includes a sensor. The control unit determines whether or not an abnormality has occurred in a calculation function of the control unit on the basis of a comparison result between the control required injection amount and the monitoring required injection amount. The control unit determines whether or not an abnormality has occurred in the calculation function of the control unit without using the comparison result when the comparison result is calculated during a predetermined period. The predetermined period is a period of a delay that occurs between updating of one of respective values of the control rotation speed and the monitoring rotation speed and updating of the other value due to a difference between the first timing and the second timing.

In an idle operating state, a learning rate of the second learned value is reduced until the first learned value converges for the first time as compared with after its convergence.

Abstract: 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.

Abstract: A control apparatus for an engine includes a control unit. The engine includes a sensor. The control unit determines whether or not an abnormality has occurred in a calculation function of the control unit on the basis of a comparison result between the control required injection amount and the monitoring required injection amount.

Abstract: 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.
