Abstract
An air-conditioning system heats the passenger compartment with coolant circulating in the water jacket of an engine. An electronic control unit of the engine controls the engine to perform homogeneous-charge combustion when the engine load is high and to perform stratified-charge combustion when the engine load is low. However, the ECU further controls the engine to perform the homogenous-charge combustion when the heating performance of the air-conditioning system is insufficient. This lowers the heat efficiency of the engine and increases heat transferred from combustion gas to the coolant. As a result, the heating performance of the air-conditioning system will be sufficient.
