    摘要： A method for controlling an engine having at least two cylinders, at least one of which having at least an adjustable valve, the method comprising before engine rotation closing electrically actuated valves in at least a first and a second cylinder; fueling at least said first cylinder with a first fuel amount and said second cylinder with a second fuel amount; and performing a first spark in at least one of said first cylinder and said second cylinder; and after engine rotation, firing each cylinder of the engine in a sequential firing order without changing a number of strokes in any cylinder of the engine.

    摘要： A fuel delivery approach for an engine includes delivering a first fuel blend from a first, lower alcohol fuel tank to a port injector; delivering a second, higher alcohol, fuel to a direct injector, and transferring the first fuel from the first tank to the second tank so that the first tank is emptied before the second. In this way, at least some fuel is available for direct injection even when the higher alcohol fuel is exhausted prior to the lower alcohol fuel. Thus, it is possible to at least obtain charge cooling benefits of direct injection, and therefore the engine may be operated with a greater amount of boost.
