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. 
  • Comfort

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