Method and apparatus for operating a spark-ignited direct fuel injection engine |
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.
