With a total of 3 patents to his name, Walker has developed innovative solutions that address the challenges associated with gaseous fuel ignition and regulation.
Latest Patents
One of Walker's latest patents focuses on "Starting a gaseous and pilot fueled engine." This invention addresses the difficulties of starting a gaseous fuelled engine at cold temperatures, which often results in reduced ignitability and combustion efficiency. The technique involves determining whether the engine is in a normal or cold start condition and adjusting the introduction of pilot fuel accordingly. During a normal start, the pilot fuel is introduced when its pressure exceeds a first threshold, while in cold conditions, a higher pressure is required. This selective introduction of gaseous fuel enhances the engine's performance.
Another significant patent is the "Method and apparatus for fuel regulation." This invention provides a method for regulating fuel during a non-motoring operating mode of an internal combustion engine. It employs a first fuel to regulate the pressure of a second fuel, ensuring efficient operation even when the engine is not actively running. The fuel injector is actuated with a specific command signal, allowing for precise control over fuel introduction into the combustion chamber.
