OIL-COOLED INTERNAL COMBUSTION ENGINE

摘要

OIL-COOLED INTERNAL COMBUSTION ENGINE An oil-cooled internal combustion engine comprises an oil pan, which contains a common oil sump for a lubricating oil circuit and a cooling oil circuit. Each of said oil circuits contains a separate oil pump said cooling oil circuit is directly connected to the oil pump and said lubricating oil circuit is connected to said cooling oil circuit and comprises an oil filter and an oil cooler. In order to permit an efficient and effective cooling of parts which are subjected to high temperatures, a secondary cooling oil circuit branches from the lubricating oil circuit behind the oil cooler and extends to engine portions which are subjected to particularly high temperatures so that they require an intense cooling.
