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： An exhaust emission control apparatus for an internal combustion engine includes a fuel injection valve placed substantially at a midpoint above a combustion chamber of the engine; a piston having an outer cavity formed substantially in a midsection of an upper surface of the piston and an inner cavity formed in a bottom surface of the outer cavity; an ignition plug placed in a region right above the outer cavity; an exhaust purifying catalyst provided in an exhaust passage of the engine; and a controller. This controller is configured to carry out a stratified charge combustion when a temperature rise for the exhaust purifying catalyst is required, by forming air-fuel mixture which is richer than stoichiometric ratio and is able to be ignited by the ignition plug, within the outer cavity and in an area substantially right above the outer cavity, from a fuel injected through the fuel injection valve.
