WE! TRAINS_UV14 – Efficient gas engine drive systems for multiple units - TRAINS_UV14-WTZ
The aim of this joint project is to develop a new type of combustion engine for the combustion of hydrogen with water injection, which can replace diesel engines in existing multiple units. This will initially be done on a prototype so that the findings can also be applied to other engines in the long term.

The project is characterized by three key innovations:
- Existing engines can be converted and run on hydrogen. The purity requirements for H2 are significantly lower than for fuel cells
- Development and retrofitting of water injection to increase performance and reduce emissions
- Direct injection is to be implemented to increase output and efficiency
Directly linked to the objectives on the engine side is the development of a refueling system that can be integrated into existing trains. On the other hand, an infrastructure for supplying the trains with hydrogen is to be designed. Other components of the project include safety and licensing as well as involving the regional population through public participation.
