RETARDING SYSTEM

A vehicle (10) includes an engine (12), a transmission (16) associated with the engine (12), and an engine retarder (30) having a deactivated state and an activated state. The engine retarder (30) is configured to provide a retarding torque to the engine (12) in the activated state. The vehicle (10)...

Beschreibung
Zusammenfassung:	A vehicle (10) includes an engine (12), a transmission (16) associated with the engine (12), and an engine retarder (30) having a deactivated state and an activated state. The engine retarder (30) is configured to provide a retarding torque to the engine (12) in the activated state. The vehicle (10) also includes a fan (48) associated with the engine (12). The fan (48) is configured to be activated in response to a selection of a transmission gear ratio greater than or equal to a threshold gear ratio while the engine retarder (30) is in the activated state. The fan (48) assists in providing additional retarding torque to the engine (12) while activated. L'invention concerne un véhicule (10) comprenant un moteur (12), une transmission (16) associée au moteur (12), et un ralentisseur (30) de moteur possédant un état désactivé et un état activé. Le ralentisseur (30) de moteur est configuré pour exercer un couple de ralentissement sur le moteur (12) dans l'état activé. Le véhicule (10) comprend également un ventilateur (48) associé au moteur (12). Le ventilateur (48) est configuré pour être activé en réaction à la sélection d'un rapport de vitesses de transmission supérieur ou égal à un rapport de vitesses seuil tandis que le ralentisseur (30) de moteur se trouve dans l'état activé. Le ventilateur (48) contribue à exercer un couple de ralentissement supplémentaire sur le moteur (12) lorsqu'il est activé.
