摘要： 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.

摘要： A method and apparatus for exhaust gas recirculation for an internal combustion engine in which exhaust gas is recirculated through a recirculation passage connecting the exhaust passage of the engine and the intake passage of the engine. A vacuum-response type recirculation control valve is disposed in the exhaust gas recirculation passage to operate in response to vacuum detected at a vacuum detection port located in the intake passage in the vicinity of a throttle valve. A vacuum tank is connected through a solenoid-actuated change-over valve to the vacuum passage interconnecting the vacuum detecting port and the recirculation control valve, the vacuum tank being in communication with the intake passage downstream from the throttle valve through a check valve. A differential pressure switch is connected between the solenoid-actuated change-over valve and a power source and is adapted to be placed in "on" state when the vacuum detected at the vacuum detecting port is lower than the vacuum in the vacuum tank to operate the change-over valve to connect the vacuum tank to the vacuum passage.
摘要翻译：一种用于内燃机的废气再循环的方法和装置，其中废气通过连接发动机的排气通道和发动机的进气通道的再循环通道再循环。真空响应型再循环控制阀设置在废气再循环通道中，以响应于位于节气门附近的进气通道中的真空检测口检测到的真空而操作。真空槽通过电磁致动转换阀连接到真空通道，该真空通道将真空检测口和再循环控制阀相互连接，真空箱通过止回阀与节流阀下游的进气通道连通。在电磁转换阀和电源之间连接有差压开关，当在真空检测口检测到的真空低于真空罐中的真空以操作时，适于处于“接通”状态将真空槽连接到真空通道的转换阀。
