Product Description

The MN170 engine adopts an underslung main bearing structure, compared with the vertical main bearing structure it features a more compact structure, higher power to weight ratio, and small vibration. The generator powered by the MN170 engine combined with all auxiliaries can be accommodated in a 20’ sound-proof container that is an efficient answer for isolated developing regions which do not have alternative energy sources and for those applications where mobility and fast installation of energy plants are required. All the following parameters are also valid for burning on HFO.
