Dual Fuel Generator Sets (Bi-Fuel Generator Sets): Refers to a power generation device that uses both fuel and gas as fuel, and an internal combustion engine as the prime mover to drive a generator, converting mechanical energy into electrical and thermal energy. It is an innovative technology that can use a mixture of fuel (diesel or heavy oil) and gas as fuel, or operate solely on fuel in the absence of gas. When the load of the unit does not reach 20%, the unit is completely driven by fuel. As the load continues to increase, gas begins to be injected and mixed with fuel for combustion. As the load increases, the amount of gas input (up to 80% or more) will correspondingly increase. The unit can quickly and flexibly switch between gas and fuel, and the optimized design of the combustion chamber ensures that both fuels have very low fuel consumption rates during combustion. It has the excellent and reliable performance of a fuel powered generator set, while also possessing the economic and environmental advantages of a gas powered generator set.


By mixing gas and fuel, fuel costs have been greatly reduced. The unit can not only use conventional fuel as raw material, but also partially replace fuel with gas, greatly reducing operating costs and emissions pollution. Suitable gas fuels include: pipeline natural gas PNG, liquefied natural gas LNG, compressed natural gas CNG, oilfield associated gas, etc; Suitable liquid fuels include diesel, heavy oil, crude oil, biofuels, etc.


SMCC Group produces and supplies gas generator sets, with the engine brands including MAN, CSSC, Caterpillar, Hyundai(HHI), Weichai, Yuchai, etc. The power range of dual fuel generator sets is from 0.6MW to 22MW.
