Introduction
Jerry L Marsh is an accomplished inventor based in Seymour, IN (US). He has made significant contributions to the field of engine lubrication systems, holding 2 patents that showcase his innovative approach to improving engine efficiency and performance.
Latest Patents
One of his latest patents is the "Electronically Controlled Lubricating Oil Removal System." This novel method and system automatically removes an engine's used lubricating oil and injects it into the engine's fuel system during operation. The system includes a removal and injection pump with a spring-biased piston forming a chamber on each side. It also features a transfer circuit connecting the chambers and a pump control device that regulates the flow between them. The pump control device can block the used oil from the engine while connecting the chambers or connect the used oil circuit to one of the chambers while blocking flow between them.
Another significant patent is the "Electronically Controlled Continuous Lubricating Oil Replacement System." This improved method continuously removes an engine's used lubricating oil and injects it into the engine's fuel system based on engine operating conditions. The system includes a lube oil replacement pump that injects small amounts of used lube oil into the engine's fuel system while recycling controlled quantities of removed used oil back into the engine's lube oil system. It periodically determines an engine's operating severity value, such as fuel consumption, and calculates a baseline quantity of oil for injection based on current fuel consumption.
