  • Engine oil capacitor
    Patent number: 5479886
    Abstract: An engine oil capacitor which allows a larger volume of oil to be used in an internal combustion engine without reducing fuel economy or increasing engine package size. Oil flow through the normal oil drainback holes is partially restricted, resulting in a substantial quantity of oil being temporarily stored in an engine compartment, such as the camshaft compartment, during engine operation.
