Abstract
A bypass is provided around a throttle valve of an engine, and a solenoid operated on-off control valve provided in the bypass so as to control flow of intake air. When the engine is accelerated in the coasting of a vehicle, an acceleration signal is produced. In response to the acceleration signal, a driving pulse train is fed to the control valve so as to reduce the intake air flow in dependence on coolant temperature of the engine by the coolant temperature.
