Product advantages


  • Emission: Euro Ⅴ Euro Ⅵ.
  • Power performance: High power, high torque (and high output torque at low speed) .
  • Economy: The optimized powertrain system ensures low fuel consumption; the engine is able to achieve high mechanical efficiency at low speed, ensuring low fuel consumption.
  • Comfort: The customized development of NVH ensures low noise and vibration.
  • Reliable

  • The movement speed of moving parts is reduced, and the movement time is prolonged.
  • The wear of friction pairs per unit time is reduced.
  • The service life of the crankshaft flywheel system and gear system is prolonged.
  • Economical

  • The maximum torque on external characteristic curve at low speed is improved.
  • The speed ratio of drivetrain is reduced, improving transmission efficiency.
  • The driver‘s shift schedule is improved, reducing fuel consumption.
  • The engine body saves energy by 5 %, and the vehicle saves energy by 10 %.
  • Comfortable

  • The high frequency torsional vibration zone of the engine is avoided.
  • The engine noise is reduced to 74 dB(A).
