HCCI: Berlin TU researchers develop clean and efficient engine

Researchers at the Technical University of Berlin have developed a first prototype of an HCCI (Homogeneous Charge Compression Ignition) engine. This clean and efficient engine could soon equip cars
Personal.

In the HCCI engine, fuel is mixed homogeneously with air, as in most gasoline engines today; ignition however takes place by compression, as in a diesel engine, but at a much lower temperature. This lower combustion temperature and the higher proportion of air virtually eliminate NOx emissions and lower pumping losses. All in all, the gain in consumption is significant.

An additional 2,2 million euros have been granted for the continuation of the project, which should continue over a period of 18 months. The project brings together several companies (including the automotive development company IAV GmbH) as well as two research groups from the Technical University of
Berlin.
