An apparatus and method for retarding an engine having a cylinder with an exhaust valve, an intake valve, an intake stroke, an exhaust stroke, a compression stroke and an expansion stroke. The apparatus includes an exhaust brake and a compression release brake. The exhaust brake includes a variable exhaust restrictor, a pressure sensor for sensing pressure of exhaust gases and a controller operatively connected to the pressure sensor and to the exhaust restrictor. Opening of the exhaust restrictor is adjusted during operation of the apparatus so exhaust pressure is sufficient to cause exhaust valve float prior to bottom dead center of intake strokes of the cylinder, thereby enhancing operation of the compression release brake.

L'invention concerne un appareil et un procédé de ralentissement de moteur comprenant un cylindre avec soupape d'échappement, une soupape d'admission, un temps d'admission, un temps d'échappement, un temps de compression et un temps de détente. L'appareil comprend un frein d'échappement et un frein à commande de décompression. Le frein d'échappement comprend un diaphragme d'échappement variable, un capteur de pression pour détecter la pression des gaz d'échappement et une unité de commande opérant avec le capteur de pression et avec le diaphragme d'échappement. L'ouverture du diaphragme d'échappement est réglée lors du fonctionnement de l'appareil de façon que la pression d'échappement soit suffisante pour provoquer l'ouverture de la soupape d'échappement avant les points morts bas d'admission du cylindre, ce qui améliore le fonctionnement du frein à commande de décompression.
