Multi-fuel options

  • Gasoline generator set with multiple gas priority(LPG/NG/Gasoline the three fuels can be easily switched in one genset, we call it 3 IN 1 genset).

  • a. Only need to connect the LPG tank in your home kitchen as a gas source.
    b. Or connect the natural gas pipe line  as a gas source.
    c. Gasoline can also be used as a fuel source .

Gas safety

  • When you stop the machine and forget to turn off the gas regulator GRETECH’s own patented  mixing system can cut off the gas very precisely.
    Never need to worry about gas leakage.

Fuel selection

  • a.Fuel consumption:LPG 0.36 kg/kW.h, Nature Gas 0.35 m³/kW.h , Gasoline 0.9 L/kW.h
    b. Economically, running cost rank (from cheapest to the highest): 1,natural gas, 2, LPG, 3, gasoline.
    c. If connected to the pipeline gas: Generator set can run for a long time, no need to refuel gasoline.


  • Power: The output power running on LPG is the same strong as gasoline, and the output power under natural gas is 90% of gasoline.
    Startup: Normally only needs 1-3 times of pulling can start GRETECH engine under LPG or NG no matter it's new or old machine.
    Working-Life: Poor combustion of gasoline and dilution with engine oil, resulting in burning carbon deposits and deterioration of lubrication conditions; Gas fuel does not have this problem, maintenance costs are less and gas generator working life is increased by 25%.
    Emissions: When using gas fuels, low harmful emissions , smokeless and odorless, benefit to environmental protection.

Easy to switch fuel

  • a. Different gas sources use the same generator set.
    b. Only need to change the position of the fuel source switch.

A number of national invention patents and practical patents

  • a. With fully automaticlly adjustment design, it will automatically adjusts the air supply volume under different loads to minimize the consumption of gasoline or gas very precisely.
    b. Own precise structure design of the mixer has his inside space small while suitable for wide range of gas source pressure (2.0~6.0kPa).

  • c. Reverse-closed design of switch diaphragm : Only supply fuel gas during engine working. Gas leakage controlled effectively.
