ABSTRACT:
A method for bypassing a controlled quantity of airflow around a throttle body of an internal combustion engine of a motor vehicle during periods of sudden deceleration of the vehicle. The method makes use of a bypass valve having an input end in communication with an air inlet of a throttle body of the engine and an outlet in communication with an air inlet of the intake manifold of the engine. When sudden closing of the throttle is sensed, or when the throttle is closed, the bypass valve is opened to a degree sufficient to enable an additional quantity of air to flow therethrough and into the inlet of the intake manifold. The invention significantly reduces the drop in engine rpm experienced during sudden deceleration of the vehicle, to thereby substantially reduce or eliminate powertrain vibration that results during sudden deceleration.
