Latest Patents

One of Eric Day's latest patents is for an electronically controlled fuel pump. This innovative design features a microprocessor that is cooled by the fuel flowing to the inlet of a positive displacement pump. The cooling passage incorporates a labyrinth flow path, allowing heat sinks of the microprocessor to transfer heat through conduction. An auxiliary pump facilitates fuel flow through the heat exchange passage during specific conditions, such as shutdown, ensuring that the microprocessor's temperature remains below a predetermined maximum. Additionally, transducers and control elements are housed in a protective cavity within the fuel pump, providing easy access for maintenance.

Another notable patent is the turbocharger boost feedback control for an engine governor. This add-on feedback control unit connects to an existing mechanical governor for turbocharged engines, regulating fuel flow in response to engine load. This innovation helps maintain an adjustable low-speed droop for the engine. The design includes a diaphragm that separates the interior chamber into two subchambers, with one side subjected to turbocharger boost air pressure. The control arm, connected to the diaphragm, provides feedback based on engine load, allowing for precise adjustments to engine speed.
