  • Control strategy for engine employng multiple injection types
    Patent number: 7581528
    Abstract: A system for an engine, comprising a cylinder, a first injection subsystem for injecting a first substance into the cylinder, a second injection subsystem for injecting a second substance into the cylinder, and an electronic engine controller configured to control a plurality of operating parameters of the engine, where the electronic engine controller is configured to cause variation of at least one of the operating parameters in response to a shortfall condition of the second injection subsystem.
    Type: Grant

  • Controlling spark of an engine with adjustable intake valve timing
    Publication number: 20060123770
    Abstract: A system and method to control spark timing of an engine wherein the injection timing of the engine is varied relative to a crankshaft position depending on engine operating conditions. According to the method, spark timing is varied as fuel injection timing varies for at least a portion of the engine operating range. The method can reduce fuel consumption, reduce transient fuel requirements, improve engine performance, and reduce CO emissions, at least under some conditions.

  • Controlling an engine with adjustable intake valve timing
    Publication number: 20060037306
    Abstract: A system and method to control an engine wherein at least intake valve timing is retarded relative to a crankshaft position depending on engine operating conditions. According to the method, at least a portion of the fuel is injected during the intake valve open period with retarded valve timing. The method can reduce fuel consumption, reduce transient fuel requirements, improve engine performance, and reduce CO emissions, at least under some conditions.
