  • Engine cranking system with cylinder deactivation for a direct injection engine
    Patent number: 7478625
    Abstract: An engine cranking system includes fuel injectors that are associated with multiple combustion chambers of an engine. The fuel injectors include a first fuel injector that is associated with a first combustion chamber. A second fuel injector is associated with a second combustion chamber. A control module is coupled to the fuel injectors and operates the first fuel injector in a deactivated state for a first chamber cycle during cranking of said engine. The first chamber cycle includes intake and exhaust strokes and is associated with a first combustion chamber.

  • MULTIPLE INJECTION BLEND FOR DIRECT INJECTED ENGINES
    Publication number: 20080196694
    Abstract: A fuel injection system for a direct fuel injection engine includes an injection mode module. The injection mode module selects a fuel injection mode to be one of a single injection mode and a dual injection mode. A fuel injection command module transitions between the single and dual injection modes by varying the timing of fuel injection events relative to a crankshaft position.

  • MULTIPLE INJECTION BLEND FOR DIRECT INJECTED ENGINES
    Publication number: 20080196693
    Abstract: A fuel injection system for a direct fuel injection engine is provided. The system includes an injection mode module that selects a fuel injection mode to be one of a single injection mode and a dual injection mode during engine operation and a fuel injection command module that commands fuel injection events based on a crankshaft position, the fuel injection mode and a fuel percentage blending schedule.
