Valve trains for commercial vehicles

Further optimization of the gas exchange in combustion engines is critical for complying with future emissions and fuel consumption targets while meeting the challenging requirements for efficiency in modern four-stroke combustion engines. The valve train plays a key role in this respect. Valve train systems control the gas exchange, which means that they represent a significant opportunity for optimizing the combustion process.

The system is continuously subjected to high mechanical loads during operation. Advances in friction reduction thus directly influence the efficiency of the entire engine. At the same time, the components still need to hold up for the required service life, which is particularly high for commercial vehicles.
