The WTZ Roßlau develops and designs single-cylinder research engines. These modular research engines allow the use of different piston diameters and strokes. They span a displacement range from around 2 to 50 liters. This means that applications ranging from commercial vehicles to marine engines can be covered. The research and development of the research engines were supported by the state of Saxony-Anhalt within the framework of funding measures.

Single-cylinder research engines are used to optimize combustion processes and validate engine components as a preliminary stage for full engine development.

The aim is to achieve the best efficiencies with the lowest possible emissions and the longest possible operating life.

In the coming years, WTZ Roßlau will increasingly investigate the mode of action of hydrogen as a promising fuel for future gas engines.
