Reliable and durable
- High reliability design guarantees the service life of 1,800,000km/30,000h.
Powerful, efficient
- Its power range is 228kW-247kW; maximum torque is 1700N.m and torque per liter is 200N.m/L, which are much better than those of competing products.
- High output torque at low speed.
Energy-saving, low fuel consumption
- It has a wide economic zone, i.e., (1000-1,400)r/min and (800-1,600)N.m, and its fuel consumption is lower than 190g/kW•h.
Capable of adapting to complex environments
- No power loss will occur under common operating conditions when the engine runs at 4,700m above sea level, and the plateau power is guaranteed.
- The engine can start normally at -20°C without auxiliary measures and -35°C with the auxiliary intake heating system, indicating a good low temperature start ability.
Safe and reliable, high braking power
- The new-generation Weichai brake system, with the braking power up to 26kW/L, is applied with the braking power adjustment technology, and thus no butterfly valve is required.
