Abstract
A throttle valve opener for a throttle valve in the intake passage of a vehicle engine is actuated by suction pressure from the intake passage, the suction pressure being weakened by introduction of atmospheric air during certain operating conditions of the engine. Suction pressure for operating the throttle valve opener is cut off when the vehicle speed or the engine RPM exceed predetermined values, or when the engine's cooling water temperature rises above a predetermined limit. This system controls deceleration of the engine to reduce exhaust pollutants without adverse effects on the drivability of the vehicle.
