CNG engine for vehicle

Characteristic                                                            

 Excelent performance:

     Wide torque band achieved using a properly matched turbocharger combined with electronic wastegate control. The ECM controls boost at all operating conditions, and uses optimized turbine energy injection software speed up turbocharger resulting in excellent vehicle acceleration.

 Optimized fuel economy:

     The ECM stops fueling during deceleration periods and uses intelligent control of the electronic throttle and wastegate to reduce demands on the turbocharger for optimized fuel economy.

 Wide environmental condition:

    The ECM utilizes readings from the engine’s sensors, including the Envirotech Sensor, to keep performance and fuel economy optimized regardless of environmental conditions such at altitude, temperature, or humidity.

 Adaptive learn:

    An oxygen sensor in the exhaust provides feedback on fuel metering and engine breathing and allows the ECM to continuously adapt to changing conditions, keeping the engine calibration optimized at all times.

 CAN Communication:

   The ECM can communicate over CAN link to make interaction with other vehicle systems easy.

 Durability and Reliability:

    The intake manifold, cylinder head, and piston etc, and have all been optimized for CNG. The excellent strength, durability, and reliability of the diesel base engine are retained in other components. Lean-burn combustion is in turbocharged engines to reduce component temperatures for long life at high power.

 Low emission:

    Exceeding the emission standards of Euro3 and has the potential of meeting Euro4.Noise level much less than desiel's, especially suitable for city transportantion.
