Abstract

An engine cooling device comprises an oil jacket surrounding a cylinder portion of an engine, an oil gallery supplying high-pressure oil to various parts of the engine, and an oil pressure regulator disposed between the oil jacket and the oil gallery to reduce the pressure of the high-pressure oil supplied from the oil gallery and to supply the oil at a reduced pressure to the oil jacket. Thus, the required mechanical strength of the oil jacket can be decreased to decrease the weight of the engine cylinder block.
