Abstract
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.
