Product advantages

  • Emission standards: Euro V and Euro VI, with advanced 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.
  • Economy: 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.
  • Comfort: Low vibration and low noise，Noise is reduced to 79dB(A) @ idling, 93dB(A) @ rated power.
