This business retrofits diesel vehicles, the main source of urban pollution, to LPG by use of the FBM and LPI methods uniquely researched and developed by EROOM G&G.

Unique new technologies certified by domestic and overseas authorities

Low-emission LPG retrofitting is EROOM G&G’s fundamental and unique technology, verified in terms of its technology both in
Korea and abroad with safety certificates acquired from the Korea Gas Safety Corporation (KGS), the Korea Transportation
Safety Authority (KOTSA), and DEKRA, Germany.

Diversified technical know-how and capabilities verified through years of retrofit accomplishments

EROOM G&G has been consolidating its technical capabilities and know-how, now having completed demo and regular projects
across the six metropolitan areas of Korea, beginning with the Low-Emission LPG Retrofit Program led by the Daegu
Metropolitan City in 2001.

This device supplies fuel with vaporizer and mixer, controlling the air-fuel ratio with mechanical devices. This technology enables the retro-fitting of dissel vehicles to LPG, a clean fuel, using independent electronic control units operated by signals from various sensors.

- Installs a spark ignition system and substitutes spark plugs for the fuel injection nozzles of a dessel engine
- Replaces a diessel fuel tank with an LPG bombe, and mounts a system that supplies LPG to the engine through vaporizer and mixer
- Applies electronic control units and three-way catalysts to reduce hazardous exhaust gas

This device injects LPG fuel in a liquid state, using injectors at the intake port of an engine. This technology enhances power and reduces exhaust gas by increasing the optimal efficiency and precisely controlling the air-fuel ratio.

- Acquired a certificate for an environment-friendly LPI retrofit business from the Ministry of the Environment, Korea
- Prepared core technologies for the control and ECU through years of research in LPI retrofitting of diesel engines
- Secured system quality with distinguished ECU mapping technology
