When a
crank angle CAa of a specific cylinder, which was expected to stop in a
fuel injection stop range over an intake
stroke to a compression
stroke at a full stop of an engine and received
fuel injection, actually exceeds the
fuel injection stop range and reaches a preset reference angle CA4, engine stop-state
ignition control of the invention ignites the air-fuel mixture in the specific cylinder receiving the fuel injection at a moment of reaching the preset reference angle CA4 (step S260) and simultaneously injects the fuel into a certain cylinder that is in the intake
stroke at the moment of the ignition (step S270). When the
crank angle CAa of the specific cylinder receiving the fuel injection does not reach the preset reference angle CA4 but exceeds a preset reference angle CA3 that is smaller than the preset reference angle CA4, the engine stop-state
ignition control of the invention ignites the air-fuel mixture in the specific cylinder upon a preset wait time elapsed after the full stop of the engine (step S295). This arrangement of the invention effectively restrains direct
discharge of the uncombusted fuel at a restart of the engine to prevent the poor emission, while ensuring quiet
combustion to reduce the potential vibrations due to the explosive
combustion.
