Abstract

An oil feeding system of an engine equipped with a transmission configured to change a rotational speed of rotation of a crankshaft and to output the rotation, including an oil pump configured to be driven in cooperation with the rotation of the crankshaft, an oil passage through which the oil outflowing from the oil pump flows, in which the oil passage includes a transmission oil passage through which the oil outflowing from the oil pump is guided to the transmission, and an engine body oil passage through which the oil outflowing from the oil pump is guided to portions other than the transmission, and an oil control portion configured to change a ratio between a pressure of the oil flowing through the transmission oil passage and a pressure of the oil flowing through the engine body oil passage.
