Good Performance
EuroⅢ and EuroⅡNatural Gas Engines for Trucks have good   performance and good fuel economy within whole power range. The engine   control system can make adjustment automatically according to change of   atmosphere, thus making the engine run without performance deterioration   at attitude of 3000m and below.
LARGE LOW-END TORQUE (SC8DT Natural Gas Engine)
Good taking off, accelerating and climbing performances.
Good Fuel Economy
Minimum fuel consumption per 100km running is less than 38m3.   The engine has lower fuel consumption within its whole operation range   compared with other engines of the same kind, which significantly   reduces truck operation cost. 
ENVIRONMENT FRIENDLY
The Engine passed national certification of EuroⅢ in 2005 and can be updated to EuroIV. 
GOOD APPLICATION ADAPTTION
Basic connecting dimensions are identical to those of the diesel version.
GOOD RELIABILITY
Small specific power(power/liter), low compression ratio. The   electronic control system is stable and reliable with minimum failure   rate.
LOW MAINTENANCE COST
Basic components are inter-changeable with the components of   the diesel version. Wear parts such as spark plug and high voltage   cables are domestic products that are inexpensive and having good   service with sufficient local spare parts.
