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.
  • 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. If the rear axle of small speed ratio is used, fuel consumption of the vehicle will be reduced by 2-3m³/100km further.
  • Comfort

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

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