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.
