PURPOSE:To improve cooling efficiency of an engine, by providing a pulsation- flow generating device in a system of cooling fluid supplied to or discharged from a cooling fluid passage. CONSTITUTION:Cooling fluid inducted from a tank 2 is pressurized being forced to be fed by a pump 3, and a part of the cooling fluid is introduced to an inlet 5 of the other cooling fluid passage excepting an atomizing-holed cooling fluid passage. A pulsation-flow generating device 6 provided in the half way controls the cooling fluid, inducted to an inlet 4 of the atomizing-holed cooling fluid passage, to be opened and closed in a fixed period, and the cooling fluid being allowed to flow pulsating is supplied to the main unit 1 of an engine. In this way, the cooling efficiency of the engine is improved. |
