Abstract
A method is provided for operating an engine to limit soot emissions during fuel-enriched operation. The method includes operating the engine using a first fuel injection pattern and timing to inject fuel into a combustion chamber of the engine. The method further includes receiving a request for an increased engine power output and operating the engine using a second fuel injection pattern and timing to inject more fuel into the combustion in response to the request for the increased power output, where the second fuel injection pattern and timing is configured to minimize soot emissions during enriched fuel operations, such as during transient operations.
