Cooling system controller of engine

Abstract

Abstract PURPOSE:To shorten a warming-up time, by controlling an electrically controlled valve device which adjusts cooling water of an engine flowing to a cooling electric fan for a radiator and the radiator by an electric controller to which a cooling water temperature is inputted. CONSTITUTION:A motor 6a which drives a cooling electric fan for a radiator, an electrically controlled valve device 11 which adjusts cooling water flowing to the radiator 5, a motor 10a driving a water pump 10 and a solenoid valve 9 for opening and closing control of a shutter of the radiator are controlled generally by a microcomputer 18 with which a water temperature sensor 14, an atmospheric temperature sensor 13 and a vehicle speed sensor 16 are connected. The microcomputer 18 stops the motors 6a and 10a, closes the electrically controlled valve device 11 and the shutter 7 of the radiator, and enables rapid warming-up when a temperature of cooling water is lower than a fixed level.
