Latest Patents
Josh Steffen holds a patent for a "Control system and method for isolating high pressure pilot fuel in dual-fuel HPDI system." This invention presents an improved fuel system for dual-fuel internal combustion engines. During normal operation, the primary fuel passes through a pressure regulator before reaching the primary fuel rail. Additionally, pressurized secondary fuel is delivered to both a secondary fuel rail and the pressure regulator to regulate the output pressure of the primary fuel. When the pressure at the primary fuel supply drops below a minimum operating pressure, the pressure regulator is isolated from the secondary fuel. The secondary fuel continues to be pressurized until it reaches a suitable pressure for operating in a limp mode. This allows the secondary fuel, which is pressurized to greater than normal operating pressure, to be injected at a higher pressure, improving engine performance in limp mode.
