The apparatus and method may be adapted to control a fuel injection system, and to operate in at least a split injection mode and a boot injection mode, including steps or means for determining whether an acceleration condition exists, and on the basis of such determination, rapidly changing from a split injection mode to a boot injection mode.

摘要： An apparatus and method for controlling fuel injection signals to an engine during a sudden acceleration event. The present apparatus and method includes an electronic controller coupled to the electronically controlled fuel injectors of the engine and operable to recognize a sudden acceleration condition based upon certain sensed conditions associated with the acceleration of the engine.

摘要： A method for operating an engine at idle that reduces NOx and controls smoke and hydrocarbon emissions. An idle delivery quantity of fuel is determined and divided into a first quantity of fuel and a second quantity of fuel in approximately equal quantities. During a compression stroke of an engine piston, the first quantity of fuel is injected into an engine cylinder. Adjusting at least one of timing and quantity of the injection of the first quantity of fuel reduces, at least in part, NOx emissions. At a timing angle of at least thirty degrees after the first quantity of fuel is injected and after the first quantity of fuel has been burned, there is an injection of the second quantity of fuel. Adjusting at least one of timing and quantity of the injection of the second quantity of fuel reduces, at least in part, smoke emissions.
