Product advantages

  • Emission standard: Euro V.
  • 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.
  • Adaptability: Two alternators and the A/C can be arranged at the front end structure to meet the different user requirements.
