Abstract
In the embodiments disclosed in the specification, an oil supply system for an internal combustion engine having an oil pan includes an oil reservoir located above the oil pan and an ascending line between the oil pan and the reservoir for delivering excess oil from the oil pan into the oil reservoir using blow-by gases produced in the engine and a flow path for resupplying used oil from the oil reservoir into the oil pan. The oil to be delivered to the individual parts of the engine for cooling and lubricating is supplied from the oil pan by a pumped delivery line and the amount of oil maintained in the oil pan is as small as possible.
