ABSTRACT:
A diaphragm operated valve bleeds air to the induction passage of a turbocharged engine when the pressure increase across the turbocharger compressor exceeds the particularly high value occurring as the engine throttle is moved from a wide open position; the additional air leans the air-fuel mixture delivered to the engine and thereby prevents a brief pulse of engine power which might otherwise occur, minimizes emission of exhaust gas hydrocarbons and carbon monoxide, and avoids exhaust system backfire noise.
