V12 gas engine for CHP.

Engineering the Future – since 1758.


MAN Nutzfahrzeuge
Efficient and Clean.
Producers and operators of cogeneration plants have stringent demands.
Robust and compact engines have to work reliably round-the-clock.
Economic operation is important for the lifetime of the complete plant.
Economic means highly efficient use of resources and low running costs
of the plant. Due to continuous development MAN engines always work
highly efficiently, reliably and environmentally-friendly.
