    摘要: In one example, a system for a vehicle travelling on a surface is described. The system includes an engine with a cylinder. The cylinder includes a fuel injector that is supplied with gaseous fuel and liquid fuel by a fuel delivery system. The fuel injector is mounted in the vehicle such that the fuel injector inlet faces at least partially toward the road surface. The orientation of the fuel injector enables a quick transition from liquid fuel to gaseous fuel because the gaseous fuel can rise to the injectors and be preferentially injected. Further, various approaches are described from transitioning operation between gaseous and liquid fuel injection.

    摘要: Systems and methods for providing heated fuel to a fuel injector of an engine are provided. According to the approaches described herein, adequate cold-start fuel atomization may be provided without compromising driver satisfaction due to excessive pre-ignition delay, while at the same time reducing unnecessary heating of fuel during warm engine off conditions.

    摘要: A method for combusting a vapor of a fuel accumulated in a crankcase of an engine, the engine disposed in a vehicle having a fuel tank and an adsorbent canister coupled to the fuel tank. The method comprises flowing compressed air from a first air source through the crankcase to yield a crankcase effluent enriched in gasses leaked from the combustion chamber, which include the fuel vapor. The method further comprises combining the crankcase effluent with an effluent from the adsorbent canister, also enriched in the vapor, and, flowing the combined crankcase and adsorbent-canister effluent to an intake of the engine via a conduit.

    摘要: Systems and methods for providing heated fuel to a fuel injector of an engine are provided. One example method comprises maintaining a volume of fuel above a start-ready temperature during a pre-start interval, the pre-start interval beginning after the engine is turned off, beginning automatically, and ending when the engine is restarted, the start-ready temperature greater than a lowest temperature of the engine during the pre-start interval. The method further comprises delivering some of the volume of fuel to the fuel injector when the engine is about to be restarted. According to the approaches described herein, adequate cold-start fuel atomization may be provided without compromising driver satisfaction due to excessive pre-ignition delay, while at the same time reducing unnecessary heating of fuel during warm engine off conditions. Further, the approaches described herein may be enacted inexpensively in a wide variety of motor-vehicle configurations.

    摘要: A method is described for operating a fuel system during start up, the system utilizing gasoline direct injection for an internal combustion engine including a first pump and second pump, an electromechanical valve, and a check valve fluidly coupled downstream of the first pump. The fuel system further includes a fuel rail downstream of the check valve and direct fuel injectors coupled to the engine. The method includes generating a flow of fuel in the fuel system via the first pump during an engine start before ignition of the engine; actuating the valve during the fuel flow to generate a pressure wave that travels through the fuel system past the check valve; and injecting fuel via the direct fuel injectors at an increased pressure generated by the pressure wave and held in the fuel rail via the check valve.
