Publication number: 20230311641Abstract: A vehicle includes a prime mover and a fuel system. The fuel system includes a tank, a regulator, a first shutoff valve, and a second shutoff valve. The tank is configured to provide a supply flow of fuel. The regulator is controllable to provide a regulated flow of fuel to the prime mover by modulating the supply flow of fuel. The first shutoff valve is positioned to facilitate selectively disengaging the prime mover from the fuel system. The second shutoff valve is positioned to facilitate selectively blocking the supply flow of fuel provided by the tank.Type: ApplicationFiled: June 7, 2023Publication date: October 5, 2023Applicant: Oshkosh CorporationInventors: Grant D.
