Cylinder head cover with pressure regulation

Even separates oil particles smaller than 1 micrometer

Hengst has already brought path-breaking solutions to market that integrate high-performance systems into other components to save space and reduce costs. It has also developed a more effective separator technology for the extremely small spaces under the valve cover. The company was quickly able to adapt the basic developments of the separator concepts to the technology under the cylinder head cover. For a... More »

Cylinder head cover with high-performance cyclone

The integrated high-performance cyclone separator removes oil mist from the blow-by gas, thereby making clean intake air available for combustion. Burnt oil produces ash which ultimately clogs the particle filter and would reduce its service life. More »
