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.


  • 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.


  • The new second-generation engine block structure improves the reliability.
  • The new fuel pipeline and coolant circuit ensure better tightness of the fuel pipeline and higher safety level of the engine.


  • Good NVH performance.
