| 摘要 |
The present invention relates to an indirect-injection internal-combustion engine, notably a supercharged engine, in particular of spark-ignition type, that can run according to a burnt gas scavenging mode or to a conventional mode, comprising at least one cylinder ( 10 ) with a combustion chamber ( 12 ), at least two air intake means ( 14, 16 ), one ( 14 ) of the means being a burnt gas scavenging intake means and the other ( 16 ) being a fuel injection intake means, said means comprising each a pipe ( 18, 20 ) controlled by an intake valve ( 22, 24 ), at least one burnt gas exhaust means with an exhaust valve ( 34 ) associated with an exhaust pipe ( 36 ) and at least one fuel injection means ( 26 ). According to the invention, the fuel injection means comprises an injector ( 26 ) with two nozzles ( 28, 30 ) allowing, when the engine runs in scavenging mode, injection intake means ( 16 ) to be supplied with fuel through one ( 30 ) of the nozzles only and, when the engine runs under conventional conditions, scavenging intake means ( 14 ) and injection intake means ( 16 ) to be supplied with fuel through nozzles ( 28, 30 ) respectively.
