A first negative pressure passage that is upstream and downstream of the throttle valve when it opens a predetermined opening amount, and a first negative pressure passage that is upstream of the opening position of the first negative pressure passage and downstream when the throttle valve opens more than the predetermined opening amount. A second negative pressure passage located in the second negative pressure passage and a negative pressure signal from the first and second negative pressure passages control the negative pressure applied to the exhaust gas recirculation valve, and the pressure for controlling the exhaust gas recirculation valve according to the operating state. an adjustment mechanism, a temperature sensor that detects the engine temperature, and according to the output from the temperature sensor, when the temperature is above a predetermined temperature, negative 7 pressure signals from both the first and second negative pressure passages are transmitted to the pressure adjustment mechanism. and a negative pressure passage control mechanism that transmits only the negative pressure signal of the second negative pressure passage to a pressure adjustment mechanism when the temperature is below a predetermined temperature.
