ABSTRACT:
An apparatus for preoiling an internal combustion engine prior to starting. This device requires no pump and is operated by vacuum and oil pressure from the engine. The apparatus is controlled by novel switching means and is recharged with hot engine oil that is drawn into a holding chamber and surrounded by an outer vacuum chamber to keep the oil warm as the vacuum serves as an insulator. This apparatus is also equipped with a dual voltage heater that can be used for warming the oil when the engine has set for long periods in cold weather. The unit is completely self contained an injects a blast of warm oil into the engine prior to starting. This reduces friction and wear to the engine. At the same time, this will reduce the load on the engine increasing efficiency at engine start-up and in turn reduce pollutants.
