| 发明名称 | Method and system for improved dilution tolerance | ||
| 摘要 | Methods and systems are provided for improving combustion stability, in particular during transient operations such as tip-out to lower load conditions, when EGR is being purged. Until a desired LP-EGR rate is achieved, fuel may be delivered as a split injection with at least an intake stroke injection and a compression stroke injection. Subsequently, single fuel injection may be resumed. | ||

| 主权项 | 1. A method for an engine, comprising: transiently shifting from single fuel injection to split fuel injection in response to each of a tip-in to high load from engine operation with lower EGR and a tip-out to low load from engine operation with higher EGR. | ||
