Low fuel consumption

       the ecu of efi cng engine gets the datas, then calculates and revises all the parameters, including gasfired temperature and pressure, suction pressure, coolant temperature, momentary response and closed loop control amendment. Precise multi-point sequential injection ensures all engines get low fuel consumpation and low emission in all conditions.

Good reliability

      the ecu of efi cng engine has self learning function. Along with the engine running, the system will be worn. No much adjustment or special maintenance is required, except simple pressure release device. The control system has

Self adapting ability to ensure the performance.
