Engine cooling system has electronic control unit that controls flow regulating valve to open to predetermined extent whenever it is detected that engine has stopped

摘要

The system cools the engine (1) by circulating cooling water in a circulation passage (4,5,10) and controls the degree of cooling depending on the engine's operating state. The rate of circulation flow is regulated by a flow regulating valve (8) and an electronic control unit (30) controls the valve so that it opens to a predetermined extent whenever it is detected that the engine has stopped.
