Abstract

A system and method of providing supplementary oil flow to an oil circuit of an internal combustion engine is described. The primary oil supply is from a mechanical oil pump. The supplementary oil supply is provided using a control system, one or more sensors, and an electrical oil pump. The system is beneficial in circumstances where the mechanical oil pump provides insufficient oil flow, including during engine shutdown.
