Abstract

A water-cooled diesel engine oil system is described, having a lubricating oil circuit (A) and a cooling oil circuit (B). To minimize the energy required to circulate the oil in the circuits, a lubricating oil pump is included in the lubricating oil circuit and a cooling oil pump is included in the cooling oil circuit, with both pumps (10) being variable displacement pumps.
