Patent number: 10865740Abstract: A fuel system for an internal combustion engine includes a liquefied gas tank that stores liquefied gas and a pressurized gas production unit connected to the liquefied gas tank to produce pressurized gas from the liquefied gas. A fuel rail is connected to the pressurized gas production unit. The fuel rail receives the pressurized gas and delivers the pressurized gas to a fuel injector that injects the pressurized gas into a cylinder of the engine. The pressurized gas production unit receives the liquefied gas via a mixing unit that is provided between the liquefied gas tank and the pressurized gas production unit. The mixing unit receives excess gas in the form of vaporized gas from the liquefied gas tank and/or pressurized gas from the fuel rail and mixes the excess gas with the liquefied gas received from the liquefied gas tank.Type: GrantFiled: March 16, 2017Date of Patent: December 15, 2020Assignee: Volvo Truck CorporationInventors: Marcus Leidefeldt, Bengt Henström, Peter Gollungberg
