Cover Story

The development of combustion engines for CV is subject to the pressures of ever more stringent limits. And different limits – depending on the use spectrum between trucks and construction machinery – also lead to development conflicts in the engine design. Achieving great versatility in the possible uses of engines, as well as low consumption and emissions, can only be done through highly sophisticated technology. The optimised gas cycle through variable valve drives plays an important role in this, as Porsche Engineering explains.

Sliding Cam Systems as Variable Valve Drive

In conventional four-stroke engines, the lift curves of the gas exchange valves are configured for a particular operating point – for example maximum engine performance. These valve lift curves represent a compromise with regard to the rest of the engine control map. With variable valve drive systems, this compromise can be resolved. This technology has been successfully used in various forms in combustion engines...
