摘要: A vehicle having an engine system which can detect an expected compressor surge event while the compressor is operating in a stable region of a compressor map, and upon detecting the expected compressor surge event controlling one or more engine operating parameters to maintain compressor operation in the stable region of the compressor map without transgressing (or mitigating the transgression of) a compressor surge line on the compressor map which, if transgressed, may cause compressor surge to occur.

摘要: 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.
