Single-cylinder prototype engines for research and development
The WTZ Roßlau develops and designs high-performance single-cylinder test engines for the research and development of modern internal combustion engines. Thanks to their modular design, these engines allow for flexible investigation of various combustion processes, engine components, and fuels. The focus is on increasing efficiency, reducing emissions, and developing sustainable engine technologies.

Development and Use of Single-Cylinder Test Engines
The WTZ Roßlau develops and designs single-cylinder test engines for various research and development tasks. The modular design of the engines allows for the use of different piston diameters and strokes.
With displacement ranging from about 2 to 50 liters, our test engines cover a wide range of applications—from commercial vehicle engines to large marine engines.
The research and development of our test engines was supported by funding from the state of Saxony-Anhalt.
Research and Optimization of Combustion Processes
Single-cylinder test engines are used to investigate and optimize new combustion processes, as well as to test and validate engine components
before they are used in full-scale engines.
Our development goals are:
- Increasing Motor Efficiency
- Reduction of Emissions and Pollutants
- Improving the Service Life and Reliability of Engine Components
- Investigation and Optimization of Innovative Combustion Processes
- Validation of new technologies for future full-scale engine development
A particular focus of our research activities is the study of hydrogen as an alternative fuel for future gas engines.
