Abstract
PURPOSE:To minimize the frequency of fan drive by setting cooling water temperature in accordance with the engine driving state, and controlling the frequency of driving the cooling fan based on the set temperature. CONSTITUTION:A control apparatus 9 is installed in order to control the drive of electric powered cooling fan 5 through relay 6, by means of the signal detected from cooling water temperature sensor 10, the vehicle speed signal from speed sensor 11 the revolution signal from distributor 12, and the load signal of engine 1 from sensor 14 which detects the opening ratio of throttle valve 13. Based on these signals, cooling water temperature suitable for the engine 1 driving state is selected in advance, and the relevant apparatus is constituted in such a way as the driving rate of fan 5 is feed-back controlled so that the cooling water temperature detected by the cooling water temperature sensor 10 may be kept at the said temperature. Thereby, the driving rate of fan 5 can be kept minimum and fuel efficiency can be improved.
