摘要： A multi-cylinder internal combustion engine is provided with a fuel injection system, which includes a plurality of fuel injection nozzles securely mounted in independent intake passages communicating with combustion chambers of respective cylinders, an air-flow sensor for detecting the amount of intake air to be led into each combustion chamber, a crank angle sensor and a cylinder discrimination sensor for detecting the present stroke timing of each cylinder, a speed sensor for detecting the engine speed and a control unit for outputting a signal to the fuel injection nozzles so that a predetermined amount of fuel may be injected to each cylinder at a predetermined timing on the basis of values detected by the respective sensors. The control unit calculates the injection timing of fuel to be injected into each cylinder so that the injection start timing may be altered in compliance with driving conditions of the engine. The control unit also calculates the amount of fuel to be injected into each cylinder on the basis of at least the amount of intake air and the engine speed. The amount of intake air is detected at a timing which is altered in compliance with the injection start timing and close to this timing.

摘要： In a fuel control system for an internal combustion engine, fuel is injected in a quantity the direct delivery part of which provides a desired quantity of fuel to be actually fed to the engine together with the drawn part of the intake-manifold wetting fuel. The quantity of the intake-manifold wetting fuel on the basis of which the quantity of the drawn part is calculated is calculated on the basis of the quantity of the adhering part of the fuel which was injected by the preceding injection and the quantity of the residual part of the preceding intake-manifold wetting fuel.

摘要： The plurality of cylinders of a multicylinder engine are divided into first group cylinders and second group cylinders, and first and second exhaust sensors are provided to respectively detect the air-fuel ratios of the intake mixtures fed to the first group cylinders and second group cylinders. The air-fuel ratio for the first group cylinders is controlled in a closed loop by a first integration signal generated based on the output of the first exhaust sensor and the air-fuel ratio for the second group cylinders is controlled in a closed loop by a second integration signal generated based on the output of the second exhaust sensor. One of the first and second integration signals is corrected so that the air-fuel ratios for the first group cylinders and second group cylinders are increased and reduced in phases reverse to each other.

摘要： An automobile engine control system estimates a required amount of intake air to be introduced at the end of an intake stroke, based on a change in a factual amount of intake air introduced prior to the end of an intake stroke, and determines a control parameter for controlling engine output based on the required amount of intake air. When the engine operates in a high pulsation range of engine loads, in which pulsation of intake air is at a high level, the determination of the control parameter is based on the required amount of intake air.

摘要： A fuel injection control system for an engine includes fuel injection valves, each of which injects fuel to one cylinder a plurality of times during each cycle. The system has an arithmetic device for calculating a required fuel injection amount based on driving conditions and a trailing side injection capability of a trailing side injection time point, a determination device for comparing the required fuel injection amount with the trailing side injection capability and determining which is greater, and a fuel injection controller for setting a leading side injection time point and a trailing side injection time point and setting a leading side injection amount and a trailing side injection amount. The fuel injection controller carries out a fuel injection only at the trailing side injection time point when the required fuel injection amount is not greater than the trailing side injection capability and divides the fuel injection between a fuel injection at the leading side injection time point and a fuel injection at the trailing side injection time point when the required fuel injection amount is greater than the trailing side injection capability.
