As a research and development service provider for combustion engines, FVTR GmbH has specialized in the field of large bore engines. The direct relationship to shipping and a long tradition in marine research at the Rostock site are the basis for our passion for large engines. Altogether, three test benches in the large engine scale are currently available for your project ideas. The powertrains of the single-cylinder research engines are partly modular allowing for different power units to be installed and operated.

Challenges in Marine Engine Development
Marine engines are the backbone of global trade and one of the most energy efficient technologies available. Nonetheless, increased public awareness of shipping as a source of pollution and the further tightening of exhaust legislation leads to considerable challenges. On top of that shipping is a major emitter of CO2 and thus responsible for a contribution to CO2 emission reduction. Both challenges are attributed by organisational measures such as slow steaming and by technical ones such as new fuels and new technologies. Against this background, we are looking forward to assisting you within your development projects.Our Development Services
- Combustion process development e.g. for new fuels
- Development of operating strategies for hybrid and transient applications
- Component testing: sensors, injection components, turbochargers and more
- Development of HFO-capable common-rail injection systems
- Test of exhaust gas treatment components under HFO operation
- Fuel and lubricant tests
- Investigation of scrubber technologies with down-scaled as well as original systems
- Study of the effect of fuels with high sulphur contents on exhaust gas treatment components
- Investigation of fouling and condensation in EGR-coolers
- Minimizing of parasitic loses at medium speed engines
