    摘要: In a control apparatus for use in an internal combustion engine (8) which has an exhaust gas sensor (20) adapted to detect exhaust gas components and provide an output signal conforming to an air-fuel ratio of mixture and which performs stratified charge combustion, signals (A/F, IGN) for controlling the air-fuel ratio of mixture and the fuel injection timing are generated on the basis of the output of the exhaust gas sensor (20). When an optimal air-fuel ratio responsible for combustion stability is changed as a result of execution of EGR and evaporative fuel purging, a change of the air-fuel ratio is determined by using the output of the exhaust gas sensor. When the influence of the EGR or the evaporative fuel purging upon the air-fuel ratio is great, the air-fuel ratio is corrected and the fuel injection timing or the ignition timing is corrected.

The control device of the high-pressure fuel pump (1) of the internal combustion engine (507) has a fuel injection valve (54) provided on a cylinder (507b) and the high-pressure fuel pump (1) for pumping fuel to the fuel injection valve (54), wherein the high-pressure fuel pump (1) comprises a pressure chamber (12), a plunger (2) for pressurizing the fuel in the pressure chamber (12), a fuel valve (5) provided in the pressure chamber (12), and the actuator (200) for operating the fuel valve (5). The control device has means for calculating the drive signal of the actuator (200) so as to realize the variable discharge of the high-pressure fuel pump (1). The means for calculating the drive signal has means for limiting the end timing of the drive signal of the actuator (200) to a predetermined phase and/or means for limiting the output timing of the drive signal of the actuator (200) to be within a predetermined phase range.

    摘要: In a multi-cylinder engine (7), amounts of fuel injection supplied to respective cylinders are individually corrected on the basis of a signal from A/F sensors (20) in the number less than the number of cylinders of the engine (7), for example, one A/F sensor (20), so that the air/fuel ratios for respective cylinders are feedback-controlled at a substantially uniform predetermined air/fuel ratio whereby it is possible to perform precise air/fuel ratio control so as to accurately maintain the air/fuel ratio of the engine (7) at the stoichiometric air/fuel ratio, thereby to reduce the concentrations of HC, CO, and NOx in exhaust gas.
