Performance characteristics

 XPI ultra-high pressure fuel injection system, precise combustion control, wide range of low fuel consumption, more fuel-efficient

Excellent overall configuration, lighter weight and more compact structure

ECM (Electronic Control Module) to monitor and control fuel injection precisely

No need for any cold start assist device, easy to start at -15 °C ambient temperature; Auxiliary device can start at -30°C

Optimized combustion amber and high piston ring, four-valve structure, low cylinder head airway vortex ratio, smoke almost zero, reaching the perfect combination of emission and economy
