George Fell is an accomplished inventor based in Norwalk, California, with a notable portfolio of four patents. His work primarily focuses on enhancing the efficiency and functionality of diesel engine systems, particularly in the area of diesel exhaust fluid (DEF) management.

Latest Patents

Fell's latest innovations include two patents for an Autonomous Auxiliary DEF Supply System with Purge Control. This system is designed to automatically supply diesel exhaust fluid to an onboard DEF tank of a diesel engine, enabling prolonged unattended operation. The system comprises an auxiliary DEF tank, an auxiliary DEF supply line, a controller, a pump, an air inlet, and a three-way valve. This configuration allows the pump inlet to switch between the auxiliary DEF tank and air. When the DEF level is low, the pump delivers DEF through the supply line to replenish the onboard tank. The controller calculates the onboard DEF tank volume based on the delivered DEF volume and data received from an engine control module (ECM). This ensures effective replenishment control, regardless of the engine's make and model. In cases of high DEF levels, engine stoppage, or system faults, the controller switches the valve to air and runs the pump for a predetermined time to purge DEF from the supply line. The auxiliary system is designed to be skid-mounted, portable, and capable of supplying DEF to multiple diesel engines.
