Friction Reduction

Reducing engine friction has gained increased importance within the automotive industry in recent years, as manufacturers are looking to improve engine efficiency and hence CO2 emissions. Friction reduction benefits can be applied across all engines, whether gasoline or diesel, from small twin cylinders to large V12s the same principles apply. Any efficiency improvements achieved will have a significant benefit on the total emissions of a vehicle fleet.

MAHLE Powertrain has proven capabilities in both designing engine for low friction and applying friction reduction technologies to existing engines. In addition to this experience, MAHLE Powertrain has direct access to the MAHLE Group's engine component and system resources. Combining the detailed base engine and component knowledge with extensive testing capabilities, MAHLE Powertrain can deliver class leading, low friction engine solutions.
