Crankcase ventilation systems for passenger cars

The blowby contains oil droplets. The deposits of them can reduce the service life and function of the components of the intake system. Compact oil separators from MANN+HUMMEL reliably separate the oil via inertial separators or fiber demisters, thus protecting the system. Various other functions like for example a pressure regulation valve can be integrated. A good oil separation is decisive for the compliance with the exhaust gas regulations for modern engines.
