Blow-by gas treating architecture for diesel engine of motor vehicle, has circuit treating blow-by gases generated during combustion, where circuit is independent from oil return circuit, and is partially formed inside engine

摘要

The architecture has an oil return circuit returning oil passing through orifices (5a, 5b) arranged on both sides of a crankcase (2) and a cylinder head (7). A blow-by gas treating circuit treats blow-by gases generated during combustion. The blow-by gas treating circuit conveys the blow-by gases from the crankcase to the cylinder head for treating the blow-by gases. The blow-by gas treating circuit is independent from the oil return circuit, and is partially formed inside an internal combustion engine (1).
