Abstract: A fuel system for an engine has a cylinder with an inlet air port, an air box surrounding the inlet air port, and a gaseous fuel injector positioned in the air box and having a nozzle located at the inlet air port. The fuel system also has a gaseous fuel control valve, a fuel supply line fluidly extending from the gaseous fuel control valve to the gaseous fuel injector, a purge valve, and a purge fluid supply line fluidly extending from the purge valve to at least one of the fuel supply line and the gaseous fuel injector. The fuel system also has a return valve and a return line fluidly extending from at least one of the fuel supply line and the gaseous fuel injector.

Abstract: An engine system is disclosed. The engine system may have an engine including at least one cylinder. Further, the engine system may have a nozzle configured to selectively inject gaseous fuel into the at least one cylinder of the engine. The engine system may also have an intake port configured to direct air for combustion to the at least one cylinder. In addition, the engine system may have exhaust valves associated with the at least one cylinder. The exhaust valves may be configured to direct exhaust from the cylinder to an atmosphere. The exhaust valves may also be configured to close at different times.
