Volkswagen has unveiled its vision of the internal combustion engine of the future. By combining aspects of diesel and gasoline engines into an engine called the Combined Combustion System (CCS), VW has developed an engine with low emissions and high efficiency. VW showed its new engine in a protoype Touran.

The CCS engine uses piezo injectors, like those in diesel engines, and begins the combustion much earlier than in existing diesels. Injected fuel is fully vaporized, which combined with early firing reduces the production of oxides of nitrogen and particulates. The CCS engine’s long burn helps to keep cylinder temperatures down, which also helps to reduces oxides of nitrogen.

Volkswagen also co-developed a new synthetic fuel with German-based firm Choren Industries. The synthetic fuel is based on a combination of planted crops, animal waste, bio-degradeable trash and forest or industrial waste.

If the new fuel is available on a large scale, Volkswagen believes the CCS engine could be ready for use in production cars as early as the next decade. VW also plans to use the CCS engine as part of a hybrid drivetrain.
