Valve trains for passenger cars

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. This applies to both gasoline and diesel 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 components of the valve train system are subjected to high loads. In addition to wear due to mechanical forces, increasing combustion pressures and temperatures, in particular, place greater demands on the materials and heat dissipation of components on the combustion side.
