摘要： In an in-cylinder injection type spark ignition internal combustion engine in which the intake air amount is controlled by use of an intake valve or an exhaust valve, which is provided with mainly a variable valve mechanism, instable combustion during a low-load operation is avoided without an increase in pumping loss (without a decrease in the thermal efficiency). In the in-cylinder injection type spark ignition internal combustion engine, during low-load operation, on the basis of the cooling water temperature of the engine the opening and closing timing of the intake valve is controlled in a retard angle manner and the opening and closing timing of the exhaust valve is controlled in an advance angle manner. Furthermore, the fuel injection timing is controlled in a retard angle manner on the basis of the retard angle amount of the intake valve opening and closing timing.

摘要： The present invention prevents an EGR sensor installed in an engine's EGR path from being soiled by soiling substances in exhaust. A catalyst is positioned upstream of the EGR sensor to purify the soiling substances in EGR gas. The status of the EGR sensor is properly controlled in accordance with the conditions of the catalyst. This ensures the EGR sensor is less likely to be affected by the soiling substances in the exhaust under any circumstances of the EGR path and allows the EGR sensor to avoid a decrease in the accuracy of EGR gas detection. An alternative configuration may be employed such that the EGR gas recirculates from the downstream side of a catalyst installed in a main exhaust path.

摘要： A first, a second, and a third combustion region are defined by the air-fuel ratio of the mixture gas feeding combustion. Upon switching of combustion regions from the first combustion region to the third combustion region and from the third combustion region to the first combustion region, namely, when the second combustion region is passed, the mass of NOx emission downstream of an exhaust purifying device and the torque variation are estimated online. Based on the estimated value of the mass of NOx emission and the estimated value of the torque variation, the mass of intake air introduced into the combustion chamber is adjusted in a manner different from when normal, such as by changing the amount of lift of the intake valve, for example, so as to reduce the mass of NOx emission downstream of the exhaust purifying device and the torque variation below predetermined values upon passing of the second combustion region. Thus, the increase in exhaust emissions and the deterioration of operability during the switching of combustion regions can be suppressed.
