PROBLEM TO BE SOLVED: To provide a cooling system for an automobile engine having an indirect air supply cooling. SOLUTION: The cooling system comprises a unit cooling circuit for cooling a heating unit having a coolant feed pump and a main coolant cooler, an auxiliary cooling circuit that is divided from the unit cooling circuit at an output point, returns to the unit cooling circuit at an input point between the main coolant cooler and the coolant feed pump, and cools an auxiliary medium including an auxiliary coolant cooler, a means for sensing a cooling temperature, and a means for adjusting a coolant flow rate as a function of the sensed cooling temperature. The means for sensing the coolant temperature is disposed in a region of the input point, or between the input point and a refrigerant feed pump. The coolant feed pump is adjusted in relation to supplied volume flow rate, a supply amount, or a supplied pressure. COPYRIGHT: (C)2004,JPO |
