Kingway three phase 30kva water cooled Natural Gas Engine for Gas generator
Kingway Gas Engine is designed and developed by Kingway Gas Power
Department , developed the controller ECU suitable for different
gas fuels, has completely independent intellectual property rights.
We can not only provide the whole gas engine, but also provide diesel engine modification service and design, manufacture and installation of the gas supply system (gas skid station).
With the strong technology, any type of diesel engine can be successfully convert into single fuel or dual fuelgas engine, there is no fundamental performance difference compared to the original machine, and can be customized according to the working and environmental conditions, so the actual use effect exceeds the original machine.
