    摘要： There is provided a control system for an internal combustion engine which controls the operation of the engine such that the combustion mode of the engine is switched between a stratified combustion mode and a homogeneous combustion mode, and torque generated by the engines is controlled based on a desired torque. The control system has an ECU which calculates a required torque based on results of detection by a crack angle position sensor and an accelerator pedal sensor, and determines a combustion mode according to the required torque. Further, the ECU smoothes the required torque in dependence on the combustion mode, to thereby calculate a smoothed required torque. Then, ECU sets the desired torque based on the smoothed required torque.

    摘要： Control system for an internal combustion engine, for setting a desired torque in response to operating conditions of the engine and controlling torque based on the set desired torque. A crank angle position sensor detects an engine rotational speed. An accelerator position sensor detects an accelerator position. A required torque is calculated based on results of detection by the crank angle position sensor and the accelerator position sensor. Further, the calculated required torque is smoothed. Then, the present value of the required torque calculated at the present time and the smoothed required torque are compared with each other. When it is determined that the engine is being accelerated, an acceleration assist amount is calculated based on a difference value between the present value of the required torque and the smoothed required torque. Then, the acceleration assist amount is added to the smoothed required torque, whereby the desired torque is set.

    摘要： There is provided a control system for an internal combustion engine, which is capable of matching an output torque of the engine with a demanded torque excellently when the combustion mode is switched, thereby enhancing drivability. A demanded fuel amount and a demanded torque of the engine are calculated according to detected operating conditions of the engine. A combustion mode is determined to be either the stratified combustion mode or the homogeneous combustion mode according to the demanded torque. A pre-switching demanded fuel injection time period and a pre-switching demanded torque are stored. When the combustion mode is switched, a switching-time demanded fuel amount (limit value) is calculated according to the stored pre-switching demanded fuel injection time period and pre-switching demanded torque, the current demanded torque, and an estimated combustion efficiency parameter.

    摘要： There is disclosed a fuel injection control system for an internal combustion engine, which is capable of properly determining fuel injection timing such that the fuel injection timing reflects behaviors of injected fuel, thereby improving drivability and fuel economy. The internal combustion engine of an in-cylinder fuel injection type is operated while switching between a stratified combustion mode in which fuel injection into each cylinder is performed during a compression stroke and a homogenous combustion mode in which the fuel injection into the cylinder is performed during an intake stroke. The fuel injection control system controls fuel injection timing. A required fuel injection time is determined based on detected operating conditions of the engine. A direct ratio and a carry-off ratio are determined based on the operating conditions of the engine. The required fuel injection time is corrected by using the direct ratio and the carry-off ratio, whereby a final fuel injection time period is determined. Based on the engine rotational speed and the final fuel injection time period, the fuel injection timing is determined.

    摘要： An exhaust gas purification apparatus for an internal combustion engine capable of lean operation has an Ir-containing selectively reducing catalyst and an NOx adsorptive catalyst. The Ir-containing selectively reducing catalyst in which iridium is an active species thereof and NOx is selectively reduced in a lean atmosphere by HC as a reducer is disposed in an exhaust system of the internal combustion engine. The Ir-containing selectively reducing catalyst is disposed on an upstream side of the exhaust system. The NOx adsorptive catalyst adsorbs NOx in the lean atmosphere and reduce the adsorbed NOx at a theoretical air-fuel ratio or at a rich air-fuel ratio. The NOx adsorptive catalyst is disposed on a downstream side of the exhaust system.

    摘要： In a direct injection spark ignition engine which is operable in lean-burn operation modes including a pre-mixture combustion mode and a stratified combustion operation mode and a stoichiometric air/fuel ratio operation mode, which are different in the desired air/fuel ratio. The degradation of combustion state is detected through misfire detection and if it is determined to be degraded, the desired air/fuel ratio, the EGR flow rate and the ignition timing are changed when the engine is operated in the stratified combustion operation mode, while the desired air/fuel ratio, the EGR flow rate and the purge flow rate are changed when the engine is operated in the pre-mixture combustion operation mode, thereby ensuring to suppress the combustion state degradation effectively.
