Abstract
An oil-cooled internal combustion engine comprises an oil pan, containing a common oil sump for a lubricating oil circuit and a cooling oil circuit. Each oil circuit contains a separate oil pump. The cooling oil circuit is directly connected to the sump and a lubricating oil circuit, comprising an oil filter and an oil cooler, is connected to the cooling oil circuit. A secondary cooling oil circuit branches off from the lubricating oil circuit dowstream of the oil cooler, and services engine portions which are subjected to particularly high temperatures, requiring increased cooling.
