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).
