| 摘要 |
The invention relates to a method of controlling an engine comprising a combustion chamber (31), fuel injection means (51), intake means (34, 35), exhaust means (43, 44) which are used selectively to authorise the release of exhaust gases (50) from the chamber (31), recycling means (58) including a first flowrate control means (59, 60) for recycling the exhaust gases (42), and a cartographic database. The method is characterised in that it comprises a step consisting in determining the operating state of the engine, a step consisting in measuring the noise from the engine Brml(n), and a step consisting in reading the database indicating a maximum acceptable noise level Brc(n) for each operating state. The method also comprises a stratification control step consisting in creating gas strata with different recycled gas concentration levels. Said method can be used to reduce the noise from the engine. |
