CNG Engine-based Generation System

In general, the engine generation system mainly uses a gasoline or diesel engine, however, our R&D center and consortium have developed a CNG-based engine generation system. CNG is a very clean fossil fuel and generates fewer pollutants. It can be supplied using the same infrastructure as city gas and provides easy scalability as shale gas.

If the CNG-based engine generation system is applied to buses, mileage can be improved and the limits of per-charge mileage can be overcome. The system can be utilized for tour buses as well as city buses.
If the static inverter that generates AC power is installed as an add-on, commercial power can be generated and play a role as a generation vehicle.
If the battery is installed at the output section of the generator control unit (GCU), it can play a role as a UPS (uninterruptible power supply).
If it is installed in a container, instead of being mounted on a vehicle, it can be used as an emergency generator, or if it is installed in a place where no power is supplied, such as in a mountainous region or on a deserted island, it can form a large generation tower.
