    摘要： An air-fuel ratio control system for an internal combustion engine having a fuel injection valve for each cylinder and an electronic air control valve (EACV) for controlling intake air bypassing the engine throttle valve. When the target air-fuel ratio is switched over from a rich value to a lean value, the amounts of fuel injected into the cylinders, for example, #1, #2, #3 and #4 cylinders are controlled so that they are sequentially decreased at predetermined intervals, and the EACV is controlled to be opened stepwise. This causes a decrease in engine torque generated by the switching-over of the target air-fuel ratio to be offset by an increase in engine torque generated by an increase in amount of air drawn, thereby preventing the generation of a torque shock. At this time, the target opening degree of the EACV is corrected based on the magnitude of the interval and the magnitude of a loading of the internal combustion engine, thereby further effectively preventing the generation of the torque shock.

    摘要： A system for controlling fuel injection in an internal combustion engine such that when the target air-fuel ratio is switched from a rich value to a lean value, the air-fuel ratios are switched to the lean value by sequentially decreasing the amount of fuel injected into the cylinders, for example in a four cylinder engine into the #1, #2, #3 and #4 cylinders, with predetermined time differences. During this time, an electronic air control valve (EACV) is controlled in such a manner that it is stepwise opened with the switching of the air-fuel ratio s for the #1, #2, #3 and #4 cylinders, thereby causing the engine torque to remain the same to prevent the generation of a torque shock. When the target air-fuel ratio has been switched from the lean level to the rich level, the amounts of fuel injected into the #1, #2, #3 and #4 cylinders are controlled in such a manner that they are sequentially increased with predetermined time differences, and the EACV is controlled in such a manner that it is stepwise closed. Thus, it is possible to avoid the generation of a torque shock, while preventing the degradation of the emission during switching of the air-fuel ratio.

    摘要： A control system controls a hybrid vehicle having an engine for rotating a drive axle, an electric motor for assisting the engine in rotating the drive axle with electric energy and converting kinetic energy of the drive axle into electric energy, and an electric energy storage unit or a capacitor for supplying electric energy to the electric motor and storing electric energy outputted by the electric motor. When the remaining capacity CAPAremc of the capacitor is smaller than a first predetermined remaining capacity REMC1 or the remaining capacity CAPAremc of the capacitor is smaller than a second predetermined remaining capacity REMC2 (>REMC1) and an assistive-mode integrated discharged value DISCHG of the capacitor 14, which is calculated while the electric motor has operated in a latest mode to assist in running the hybrid vehicle, is greater than a predetermined discharged quantity disch1, the control system calculates a regenerated quantity increasing corrective coefficient Kregup (>1) depending on the vehicle speed. The control system multiplies a basic decelerating regenerative quantity DECreg by the corrective coefficient Kregup to determine a demand output power MOTORpower for the electric motor for thereby increasing the amount of electric energy regenerated by the electric motor when the hybrid vehicle decelerates.
