Take out diesel-fueled engine and modify (making) and add some parts to convert it to LPG fuel engine

Control the emissions by the cleaning characteristics of fuel, engine control unit (ECU) and 3-way catalyst.


  • Output, fuel efficiency and emissions in LPG-installed vehicle are same as ones originally made as LPG vehicle.
  • Type of LPG-Calibrated Engine: Currently existing mixer and LPLi fuel spray
