摘要： An engine control apparatus has an electric discharge device, a voltage application device, a fuel supplying device, and a control unit. The electric discharge device includes a first electrode and a second electrode. The second electrode is arranged opposite the first electrode to produce radicals within a combustion chamber of an internal combustion engine by a non-equilibrium plasma discharge that is generated between the electrodes before autoignition of the air-fuel mixture occurs. The voltage application device is operatively coupled to the first electrode for applying a voltage between the first and second electrodes to generate the non-equilibrium plasma between the first and second electrodes. The fuel supplying device forms an air-fuel mixture inside the combustion chamber. The control unit is operatively coupled to the electric discharge device to set a discharge start timing of the electric discharge device to occur during an intake stroke of the internal combustion engine.

摘要： A split injection of gasoline produces stratified charge in at least one cylinder. A sensor measures cylinder pressure or knock and generates a sensor signal indicative of combustion event timing of stratified charge. From the sensor signal, a controller determines an actual value of a characteristic parameter representing combustion event timing in the cylinder. The controller modifies at least one of operating variables governing a split injection for the subsequent cycle in such a direction as to decrease a deviation between the actual value of the characteristic parameter and a target value thereof toward zero.

摘要： A direct fuel injection internal combustion engine comprises a combustion chamber, a fuel injection valve and a spark plug. The combustion chamber has a piston including an outer cavity located in a top surface of the piston and an inner cavity located in the outer cavity. The outer and inner cavities are substantially axially symmetrical about the reciprocation axis of the piston. The fuel injection valve is arranged adjacent the reciprocation axis of the piston to inject a fuel stream directly into the combustion chamber. The spark plug is arranged adjacent the reciprocation axis of the piston to ignite a fuel-air mixture inside the combustion chamber. The direct fuel injection internal combustion engine further comprises a control unit configured to vary at least one of frequency and start timings of the fuel injection valve based on an engine operating condition.
