摘要： A fuel injection control system for a cylinder injection type internal combustion engine, which system suppresses occurrence of torque shock upon changeover of combustion modes while protecting combustion performance of the engine from degradation to thereby enhance drivability of a motor vehicle equipped therewith. The control system includes a means (21) for detecting cylinder-charged intake air quantity information (Qai), a means (22) for setting a combustion mode (M) of the engine, a means (24) for setting a desired air-fuel ratio (A/Fo), a means (25) for setting a desired intake air quantity (Qao) conforming to the combustion mode, a means (27) for setting a fuel injection quantity (Qf) for the fuel injector means (13) so that the desired air-fuel ratio (A/Fo) is realized, a means (26) for setting a throttle valve opening degree so that the desired intake air quantity can be realized, and a means (23) for changing over the combustion modes. The fuel injection quantity control means (27) is comprised of a combustion-mode-changeover-oriented fuel injection quantity control means (28) for altering the fuel injection quantity so that it changes in reverse phase relative to the change of the cylinder-charged intake air quantity upon changeover of the combustion modes.

摘要： A control system for a cylinder injection type internal combustion engine is capable of realizing improvement of the combustion state and reduction of harmful components contained in an exhaust gas by enhancing an air-fuel ratio control accuracy in EGR control. The system includes an air flow sensor for detecting a quantity of intake air, an air-fuel ratio sensor for detecting an air-fuel ratio of exhaust gas, means for controlling exhaust gas recirculation quantity to a desired exhaust gas recirculation quantity by means of an exhaust gas recirculation regulating means, and means for setting a fuel injection quantity of the fuel injection valve in dependence on a controlled desired air-fuel ratio within engine cylinder, intake air quantity and injection mode being validated. The exhaust gas recirculation quantity control means performs a feedback control on the exhaust gas recirculation quantity so that the air-fuel ratio of the exhaust gas coincides with the desired exhaust gas air-fuel ratio.
