Abstract
A crankcase ventilation system may include a first exhaust flow path configured to permit flow of main exhaust gases from a combustion chamber of an internal combustion engine and a particulate trap disposed in the first exhaust flow path. The system may also include a second exhaust flow path configured to enable flow of crankcase gases from a crankcase of the internal combustion engine and to merge the crankcase gases with the main exhaust gases at a point in the first exhaust flow path located downstream of the particulate trap.
