Explosion internal combustion engine for motor vehicle, has cooler arrangement including low temperature cooling circuit with air heat exchanger that cools compressed combustion air and condenser heat exchanger

摘要

The engine (1) has a cooler arrangement (3) including a low temperature cooling circuit (33) with an air heat exchanger (39) via which a coolant (31) and combustion air (9) pass. The heat exchanger cools the compressed combustion air and a condenser heat exchanger (47) of a condenser (43) for an air-conditioning system (45) of a motor vehicle (5). The coolant passes through and cools the condenser heat exchanger. The cooling circuit operates independent of a low temperature level. The cooler arrangement has a high temperature cooling circuit for dissipating combustion heat.
