Product advantages

Power performance

  • Improved output torque at low speed and maximum torque and good responsiveness during acceleration and start-up meet the power requirement of the vehicle.


  • The fuel economic zone shifts to the low speed range; squish effect is strengthened and combustion speed is increased.
  • The intelligent ignition coil increases ignition energy, reduces load cycle variation of low-speed part, and reduces fuel consumption.
  • If the rear axle of small speed ratio is used, fuel consumption of the vehicle will be reduced by 2-3m3/100km further.


  • Low vibration and low noise (2 dB lower than that of competing products).


  • Two alternators and the A/C can be arranged at the front end structure to meet the different user requirements.
