ABSTRACT:
A lubrication system for internal combustion engines including an electrically operated oil pump, a conduit, an electrical time-delay relay, a one-way valve and a pump bypass. Another conduit and electrical time-delay relay may be used with turbocharged engines. The lubrication system pressurizes engine oil when the mechanical oil pump is not fully operational. In a preferred embodiment, the lubrication system has an oil filter adapter which includes a one-way check valve.
