Abstract
An oil-metering system for an internal combustion engine including an oil tank for supplying oil to the lubrication areas of the engine. The plurality of individual oil supply conduits are provided for supplying oil to lubrication areas. A pumping and control means individually meters oil supplied by the oil tank and supplies to the lubrication areas or returns oil to the oil tank. A single oil-return manifold connects the pumping and control means by a plurality of individual return conduits. The oil return manifold and pumping and control means are commonly mounted in close proximity to each other in order to reduce the length of the return conduits.
