Abstract
To prevent a drop in a lubricating oil supply pressure in a valve train from occurring by disposing a lubricating oil supply path for the exclusive use of the valve train without allowing the lubricating oil to flow through an oil gallery, thereby securing a sufficient amount of supply of the lubricating oil in the valve train to enhance lubrication efficiency. A feed pump rotating with a crankshaft is disposed at a leftward end of the crankshaft. Lubricating oil supplied from the feed pump flows through an oil cooler and an oil filter. Part of the lubricating oil is supplied through a lubricating oil supply path to an oil gallery and to journals, crankpins, and the like of the crankshaft. The other part of the lubricating oil is supplied through lubricating oil supply paths for the exclusive use of the valve train.
