    摘要: An engine control apparatus which may be employed in automotive vehicles. The engine control apparatus is equipped with a controlled variable arithmetic expression which defines correlations between a plurality of combustion parameters and a plurality of controlled variables of actuators for control of an operation of the engine to calculate a combination of command values to be outputted to the actuators for regulating the controlled variables needed to achieve target values of the combustion parameters. When one of the command values is produced outside an allowable operation range of a corresponding one of the actuators, the engine control apparatus corrects or limits the one of the command values to an upper or a lower limit of the allowable operation range, thereby ensuring the stability in bringing engine output characteristics close to desired values.

    摘要: An injection ratio control system for an internal combustion engine performs a multi-injection, in which multiple pilot injections and a main injection are performed. The system prohibits a first injection among the pilot injections if a main injection quantity command value for the main injection is less than an N time(s) minimum guarantee determination value. An injection quantity for the first injection is added to the injection quantity for the main injection. Thus, the system controls an injection frequency per combustion in the multi-injection to prevent the use of a minute main injection quantity command value equal to or less than the N time(s) minimum guarantee determination value. As a result, the main injection is prevented from vanishing.

    摘要: A fuel injection system carries out a multi-injection. A preceding injection affects a pressure in a combustion chamber at a succeeding injection. In order to ensure an amount and timing of a succeeding injection, the ECU carries out a compensating process. In one embodiment, an injection period for the succeeding injection is corrected by varying a corrective value in accordance with parameters indicative of a pressure deviation. In another embodiment, each of the injection amounts for preceding and succeeding injections is corrected in accordance with deviations from a standard pressure respectively. The deviation is determined based on an intake pressure.
