Product advantages

Emission standards

  • China V and China VI, with advanced Bosch/Woodward electronic control system adopted.

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.


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