Abstract
The idling speed of an internal combustion engine is adjusted in accordance with the required performance of an evaporator of similar air cooler in a vehicular air conditioning system. Sensors monitor engine conditions pertinent to idling speed, including the air temperature at the output of the evaporator. If the evaporator is required to work at peak output, the idling peak is also increases to a maximum. As the load on the evaporator drops, so does the idling speed.
