    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: A multicylinder engine is provided with a fuel injector for each cylinder. An ECU defines a fuel injection condition of the fuel injector based on an engine driving condition and executes a fuel injection control for each cylinder based on the defined fuel injection condition. The ECU computes an engine speed with respect to each cylinder. While the engine is running, the fuel injection condition is operated in an operation cylinder. A fuel property is determined based on the engine speed of the operation cylinder and an engine speed of a non-operation cylinder.

    摘要: A fuel injection characteristic sensing device obtains an injection characteristic of a target injector (an injector of each cylinder of a multi-cylinder engine) at each time. The device has a program for sequentially sensing fuel pressure at a sensing point corresponding to a fuel pressure sensor, which is provided at a fuel inlet of each injector, based on an output of the fuel pressure sensor. The device has a program for detecting predetermined timings (injection timings such as an injection start timing and an injection end timing) in a series of operations concerning fuel injection of the injector of each cylinder based on the sequentially sensed fuel pressure. Thus, the injection characteristic at each time including a temporal characteristic change can be obtained.

    摘要: A fuel injection detecting device computes an actual fuel-injection-start timing based on a falling waveform of the fuel pressure detected by a fuel sensor during a period in which the fuel pressure decreases due to a fuel injection rate increase. The falling waveform is modeled by a modeling formula. A reference pressure is substituted into the modeling formula, whereby a timing is obtained as the fuel-injection-start timing.

    摘要: An engine control system for managing a schedule of execution of engine control tasks is provided. The system works to schedule execution of the engine control tasks upon receipt of requests to initiate the engine control tasks. The system determines a sequence of execution of the engine control tasks and allocates execution times for which the engine control tasks are to be executed so as to provide chances of execution of the engine control task as evenly as possible. The system may determine required time-sharing ratios of the engine control tasks based on statuses of execution of the engine control tasks.
