Abstract
There is provided an engine cooling system, in which operation tendency information calculating section provided in a control unit calculates values representing the tendency of engine operation, and a control valve provided in a cooling water circulating device is controlled based on the values. It is therefore possible to control the cooling water to a proper temperature conforming to the engine operating condition and improve both the engine power and the fuel economy.
Claims14
An engine cooling system, comprising:
- a cooling water circulating device that circulates cooling water for an engine;
- a regulating device provided in said cooling water circulating device for regulating a cooling action on the engine by the cooling water;
- an operation tendency information calculating section that calculates a value representing a tendency of engine operation;
- and
- a cooling water temperature control section that controls said regulating device such that the cooling water has a lower temperature in a case where the value representing the tendency of the engine operation is a value representing a tendency to require more engine power than in a case where the value representing the tendency of the engine operation is a value representing a tendency to require less engine power.
An engine cooling system, comprising:
- a cooling water circulating device that circulates cooling water for an engine;
- a regulating device provided in said cooling water circulating device to regulate a cooling action on the engine by the cooling water;
- and
- a control unit that controls said regulating device according to a tendency of engine operation.
A method of controlling a temperature of cooling water in an engine cooling system, comprising:
- calculating a value representing a tendency of engine operation;
- and
- controlling a temperature of cooling water based on the calculated value representing the tendency of the engine operation.
