Product advantages

Emission standard

  • Euro V.

    • Power performance

  • The four-valve structure effectively significantly improves output torque at low speed and maximum torque, as well as responsiveness during acceleration and start-up.

    • Economy

  • The rated speed is reduced to 2300rpm, the absolute fuel consumption in bench test is reduced by 3%, ensuring a wider economic speed range; 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.

    • Reliability

  • The new-type ECU has a good resistance against heat, vibration and electromagnetic in
