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.

Further information

The pressure control valves commonly used today have elastomer membranes and are unable to resist the attacks of aggressive chemicals. Now with RobustPlus MANN+HUMMEL has developed a new material for pressure control valves which offers the highest chemical resistance.

Higher pressures, smaller droplets: the requirements regarding oil separation in connection with crankcase ventilation are increasing. The new Lon­gLi­fe fiber demister from MANN+HUMMEL meets these requirements. It separates even the smallest droplets highly efficiently and in addition offers greater design flexibility.
