構造。 An oil pump is mechanically connected to the crankshaft, and as the oil pump rotates, it sucks up lubricating oil from the oil pan and supplies it to the main oil supply path.
From this main oil supply passage, oil is supplied to auxiliary oil supply passages that communicate in series with the main oil supply passage at a predetermined interval, and from these auxiliary oil supply passages, oil is supplied to the bearings between the conrod fitting parts of the crankshaft. The main oil supply path is provided with a relief valve that is provided at an end further downstream than the connection portion of the auxiliary oil supply path located at the most downstream position and opens when a predetermined pressure or more is detected. Engine lubrication structure.
