Product advantages
Power performance
- The engine is able to achieve high output torque at low speed, and has better power performance, gradeability and acceleration performance when compared with similar products.
Economy
- The fuel economic zone shifts to the low speed range, and the reasonable matching of transmission and axle allows the engine operating speed to be distributed in the low speed range, so as to reduce fuel consumption.
Comfort
- Low vibration and low noise (2 dB lower than that of competing products).
Adaptability
- One alternator, two alternators, three alternators and the A/C can be arranged at the front end structure to meet the vehicle requirements.
