Abstract:
In a multi-cylinder internal combustion engine with an oil being sucked from an oil reservoir portion by an oil pump and supplied to individual portions of the internal combustion engine through an oil filter and an oil cooler, the invention improves the mounting position of a case containing an element of the oil filter, thereby to facilitate the attachment and detachment of the case for replacement of the filter, to devise the mounting position of the oil cooler, thereby to enable oil cooling by an air-cooling effect of a running airflow, to devise the position of supply of the oil to a main gallery, thereby contrive uniformization of an oil pressure supplied to individual bearing portions and uniformization of cooling of the individual bearing portions, to devise a balancer position, and thereby to balance weight in the left-right direction of the internal combustion engine. In the invention, the oil filter is mounted to a side surface of the internal combustion engine, the oil cooler and the balancer are mounted to a front central portion of the internal combustion engine, and the oil discharged from the oil cooler is introduced to a substantially central portion of the main gallery.
