Abstract

L'invention vise à améliorer la carburation dans la plage du régime nominal de ralenti. A cet effet, le régime du moteur à combustion interne est augmenté (> 800 tr/min) au moyen d'un démarreur-alternateur (KSG) accouplé au vilebrequin. Le papillon est réglé sur une valeur définie, et de préférence maintenu fermé. En raison du débit massique d'air élevé du moteur à combustion interne, la pression (MAP) dans la tubulure d'admission chute rapidement. L'injection de carburant est déclenchée uniquement lorsque la pression (MAP) dans la tubulure d'admission est devenue inférieure à une valeur seuil préallouée (MAP_SW).
