Introduction
John Karspeck is a notable inventor based in Loveland, Colorado. He has made significant contributions to the field of fuel injection systems, holding a total of 3 patents. His work focuses on enhancing the efficiency and functionality of gaseous fuel systems.
Latest Patents
One of Karspeck's latest inventions is the Asynchronous Rotary Fuel Valve. This innovative device features a housing that defines both a gaseous fuel inlet and outlet. A rotor within the valve creates an internal flow passage that alternates between allowing and blocking gaseous fuel flow based on the rotor's position. The design includes a seal that is biased to contact the rotor's exterior surface, ensuring effective operation. Additionally, an actuator is rotably coupled to the rotor, allowing for precise control based on engine speed.
Another significant patent is the Pressure Regulating Mass Flow System for Multipoint Gaseous Fuel Injection. This electronic pressure regulation system (EPRS) is designed for multipoint fuel injection engines. It employs an electronic pressure regulator capable of accurately determining and controlling the mass flow of gaseous fuel into a fuel rail. This innovation helps prevent pressure droop and ensures optimal operation of gas admission valves (GAVs), allowing for accurate and repeatable performance.
