ABSTRACT:
The cavitation prevention system according to the present invention is provided with an air introducing passageway for introducing an air within means for storing air, such as a water tank, into a cooling water passageway at a suction portion of a water pump. The means for storing air is provided with an air metering means for controlling an amount of air to be supplied to the cooling water circulating passageway, thereby to maintain an air mixture ratio at the desirable valve for effectively preventing cavitation erosion. An air flow control valve means mounted to the air introducing passageway is controlled by output signals from means for detecting various conditions of an engine in which cavitation occurs or cavitation teuds to occur accurately, wherein the air is introduced into the cooling water only when the engine condition requires it to prevent cavitation, but at other conditions of the engine the air introduction is not effected so as to improve the engine cooling performance.
