摘要： A technique is provided for regulating gas entrainment into a fuel spray in a fuel-injected engine. The fuel spray issues from a nozzle positioned in a gas entrainment shrouding recess, such as in the cylinder head. The depth and elevational profile of the recess are selected to provide a desired degree of gas entrainment. By reducing gas entrainment, a desired spray shape may be established or maintained, such as a hollow cone. More gas entrainment may be provided by altering the recess geometry, and that of the combustion chamber surrounding the recess, to modify the spray or the spray distribution, such as to partially or fully fill a spray cone.

摘要： A spray penetration control method that controls penetration of fluid injected as a spray from an injector. The control method uses multiple successive injection events instead of single injection events to reduce overall spray penetration. Dwell times may be fixed or varied between successive injection events to reduce overall spray penetration. Also, the mass of fluid spray injected by the injector may be fixed or varied during each multiple successive injection event to reduce overall spray penetration and the number of successive injection events may be adjusted so that a desired total amount of mass is delivered in accordance with a desired penetration.

摘要： A method and article of manufacture are provided to operate a spray-guided, spark-ignition, direct fuel injection engine, including injecting a first fuel pulse during a combustion cycle, and initiating spark ignition by energizing a spark igniter. A second fuel pulse is injected during the combustion cycle effective to form an ignitable fuel-air mixture proximal to the spark igniter during a period in time whereat the spark igniter is energized. A preferred elapsed time between an end of the first fuel pulse and start of the spark ignition is determined based upon engine load.
