Product advantages

Power performance

  • The new-type ECU is used and thus the maximum torque is increased by 7%.
  • The four-valve structure effectively significantly improves output torque at low speed and maximum torque, as well as responsiveness during acceleration and start-up.


  • The precise control of the new-type ECU increases economy by 4%.
  • 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 further.


  • The new-type ECU has a good resistance against heat, vibration and electromagnetic interference, and is directly installed on the engine.
