Cooling apparatus for vehicular engine

摘要

The invention provides a cooling apparatus for a vehicular engine which can improve the life of at least one of, an exhaust gas recirculation unit and an intercooler.With the cooling apparatus for a vehicular engine of the invention, then with a vehicular engine (an automobile in this example) provided with at least one of an exhaust gas recirculation unit (EGR) 50a and an intercooler 50 for a turbocharger 100, there is provided a radiator 9, and an electric pump 53 for circulating coolant to carry heat generated by at least one of the exhaust gas recirculation unit (EGR) 50a and the intercooler 50 to the radiator 9. When the automobile engine 3 is stopped, the operation of the electric pump 53 continues for a fixed period so that the coolant cooled by the radiator 9 is circulated to at least one of the EGR 50a and the intercooler 50b to provide cooling to thus rapidly reduce the temperature. The electric pump 53 is then stopped when a low temperature is reached.
