Technical Examples

An engine has variable-valve mechanisms. An engine control system has an engine control unit for executing automatic stop and start control. At an automatic-stop, the variable-valve mechanisms are controlled to obtain a valve operation characteristic suitable for a restart of the engine. When a catalyst is in an inactivated state, the variable-valve mechanisms are controlled to reduce the amount of residual gas leaking out from cylinders. At an automatic-start, the control of the variable-valve mechanism is prohibited and an intake air is adjusted by using a throttle valve. At an automatic-stop, the engine speed is abruptly reduced so that the engine speed passes through a resonant revolution speed area in a short period of time. When the voltage of a battery is low, the control of the variable-valve mechanism may be prohibited.
