Abstract

Un dispositif de régulation de régime pour moteur diesel comprend un élément de régulation d'huile (1) d'une pompe à injection, une goupille creuse (2), un module de commande, un moteur (3) et son arbre (4), une tige (5), et un levier de régulation de régime (7) etc. Le régulateur ne comporte pas un régulateur de régime centrifuge mécanique et commande le moteur (3) par le biais d'un signal de charge à l'aide du module de commande et, il transfère le déplacement angulaire du moteur (3) par rapport au déplacement angulaire de l'élément de régulation d'huile (1) de la pompe à injection par l'utilisation d'une série de dispositifs d'entraînement. En comparaison au régulateur de régime centrifuge mécanique traditionnel, la pièce mobile du régulateur de régime est plus légère, a une inertie inférieure et est plus sensible. Le levier de régulation de régime (7) adopte un certain rapport de levier et rend plus précis le déplacement de pas du moteur pas-à-pas (3) et le transmet à l'élément de régulation d'huile (1) de la pompe à injection, ce qui permet de réguler l'alimentation en huile rapidement et avec précision et de diminuer le rapport de fluctuation de régime rotatif propre au diesel.
