Abstract
In an engine control unit, information showing the operation of the non-operation of the cooling fan, information showing the temperature of the coolant flowing out of the engine (1) or other parameters showing the engine operation are supplied. In the engine control unit, the temperature drop of the coolant brought about by the radiator on the basis of the operation of particularly the cooling fan is programmed to be read out from a map construction in the form of a table such that the temperature control is performed by predicting the change of the coolant. Therefore, it is possible to operate the engine at a high temperature not reaching a state of overheating such that fuel economy is attained while minimizing the generation of a poisonous exhaust gas.
