CA 2155268

A structural baffle for reducing both crankshaft torsional vibration and oil aeration in an internal combustion engine. The baffle includes a baffle plate and a number of upright members. The baffle plate isolates the oil reservoir from the turbulence generated by the crankshaft, and includes openings allowing oil flowing from the engine to return to the oil reservoir. Preferably, the baffle plate includes a number of oil return towers which align with the oil return ports of the engine to channel oil to the reservoir. The upright members are mounted to the bearing caps both to bolster the bearing caps and to support the baffle plate beyond the throw of the crankshaft.

Chicane structurale pour réduire la vibration torsionnelle du vilebrequin et l'aération de l'huile dans un moteur à combustion interne. La chicane comprend une plaque de chicane et un certain nombre d'éléments verticaux. La plaque de chicane isole le réservoir d'huile de la turbulence générée par le vilebrequin, et elle comporte des ouvertures permettant à l'huile s'écoulant du moteur de retourner au réservoir d'huile. De préférence, la plaque de chicane comprend des tours de retour d'huile qui s'alignent avec les orifices de retour d'huile du moteur pour canaliser l'huile vers le réservoir. Les éléments verticaux sont montés sur les chapeaux de palier pour les rehausser et pour supporter la plaque de chicane au-delà des manetons du vilebrequin.
