Tiny component. Massive effect.

​​​​​​​The differential pressure regulated oil separator, or DDG separator for short, combines two essential basic functions in one combined module with "cleaning" and "venting" of the crankcase. Microscopically small oil particles are filtered out of the crankcase ventilation gases during cleaning, which would otherwise enter the combustion chamber and worsen the exhaust gas values.

At the same time, the DDG oil separator keeps the pressure in the crankcase at a constant negative pressure level - even under extremely fluctuating engine operating conditions. This venting of the crankcase ensures that no gases or oil particles can escape from the crankcase into the environment, even in the event of minor leaks.

In combination with our multi-level suction jet pumps, the DDG separator can be expanded into an active oil separation system with significantly higher filter efficiency. Already today, this system can meet the expected future regulatory requirements such as EU7 or CARB.
