Japanese Patent JPH0263098
Kind Code:
B2
Abstract:
An engine comprising a main intake passage having a throttle valve therein. A bypass passage is branched off from the main intake passage located upstream of the throttle valve and is connected to the main intake passage located downstream of the throttle valve. A flow control valve, actuated by a step motor, is arranged in the bypass passage. When the engine is operating in an idling state, the step motor is rotated in a rotating direction wherein the engine speed approaches a desired idling speed. An air conditioning device is provided, which comprises an air duct, an evaporator arranged in the air duct, a heat exchanger arranged in the air duct, and an air mixture damper for controlling the flow of air which has passed through the evaporator. The desired engine speed is increased when the temperature of air, which has passed through the evaporator, becomes higher than a predetermined temperature and when the entire air, which has passed through the evaporator, directly flows into the driver's compartment without passing through the evaporator.
