Abstract

PURPOSE: To prevent over enriching by shifting the fuel-air ratio toward high concentration with a self-compensation thereof through EGR when the engine is cool and suspending EGR when the engine runs at a high speed.
CONSTITUTION: A three-way solenoid valve 15 is arranged in the course of a negative pressure passage 14. When the valve 15 is out of action a negative pressure chamber 11b is communicated to a negative pressure outlet 13. On the other hand, when the valve 15 is in action, the chamber 11b is opened to the atmosphere. The valve 15 is provided with a controller 16 which is connected with a device 16 for detecting the warming-up condition of the engine and a device 18 for detecting the presence of the transmission gear at a high speed position. The valve 15 operates only when an actuation signal from both the devices 17 and 18 are inputted to the controller 16 at a time.
