Method and equipment for cooling vehicle heat engine, comprises calculator which receives engine load and entry and exit temperatures and controls coolant pump, radiator fan and radiator bypass valve

摘要

A calculator (13) receives engine load data (15) and exit and entry engine temperatures (3,10). The cooling circuit has a radiator (6) and a radiator fan (14), bypass valve (4) and coolant pump (9) which are all controlled by the calculator. The engine exit temperature has a threshold value which is varied inversely with engine load so that at high loads there is a greater margin of safety Independent claims are made for the equipment used by the cooling system
