Abstract

L'invention concerne un procédé de contrôle d'un moteur suralimenté à allumage par compression, dont le turbocompresseur comprend un compresseur associé à une vanne de décharge à l'admission. Selon l'invention, lorsque le moteur fonctionne à l'état non allumé, en l'absence d'injection de carburant, on ferme la vanne d'admission des gaz du moteur. On peut en outre ouvrir la vanne de décharge à l'admission. On réduit ainsi l'apport d'air chargé en oxygène à un dispositif de dépollution du moteur, ce qui évite de le refroidir. On évite aussi le pompage du compresseur en ouvrant la vanne de décharge à l'admission.The invention relates to a method for controlling a supercharged compression-ignition engine, the turbocharger of which comprises a compressor associated with an inlet discharge valve. According to the invention, when the engine is operating in the unlit state, in the absence of fuel injection, the engine gas inlet valve is closed. The discharge valve can also be opened at the inlet. This reduces the supply of oxygen-laden air to an engine depollution device, which avoids cooling it. The pumping of the compressor is also avoided by opening the discharge valve at the inlet.
