Title (EN) CRANKCASE VENTILATION SYSTEM WITH DEAD SPACE ALIGNMENT SLEEVES
(FR) SYSTÈME DE VENTILATION DE CARTER AVEC MANCHONS D'ALIGNEMENT D'ESPACE MORT
Abstract:
(EN) A cylinder aligning sleeve and adapter plate for use within an internal combustion engine. The sleeve includes apertures placed contiguously with holes within the adapter plate to form a flow passage through the dead space between compression and crosshead pistons. The flow passage exits to a vent line where gas detection may occur along with safe venting of any gas detected. The sleeve serves to ensure concentric alignment of the compression cylinder with the engine block bore.
(FR) L'invention concerne un manchon d'alignement de cylindre et une plaque d'adaptateur destinés à être utilisés dans un moteur à combustion interne. Le manchon comprend des ouvertures placées de manière contiguë avec des trous à l'intérieur de la plaque d'adaptation pour former un passage d'écoulement à travers l'espace mort entre les pistons de compression et de crosse. Le passage d'écoulement sort vers une conduite d'évent où une détection de gaz peut se produire ainsi que la ventilation sûre de tout gaz détecté. Le manchon sert à assurer un alignement concentrique du cylindre de compression avec l'alésage de bloc moteur.
