Extreme reliability
- The engine has a high degree of reinforcement and a large design surplus, and the total length of the bench test has exceeded 15,000 hours, while the total length of the road test has exceeded 50 million kilometers
- Life exceeds 1.8 million km/30000 hours
Modular design
- Parts are more than 30% less than similar products - integrated fuel filter module, primary filter and fine filter integrated design
- Filter module, oil filter, cooling, rotor filter, water filter integrated design
- Integral cylinder head with integrated air intake pipe for compact design
Lightweight design
- The total machine weighs only 805kg - powerful CAE analysis capability, optimized design while maintaining strength and reliability
Intelligent control
- Self-contained ECU, fully self-developed, responsive, high-precision air control system
- Total performance, multi-level control strategy
Excellent NVH performance
- Less than 96dB(A) per meter of rated power point - the body is drum-shaped skirt design, with high body strength and low vibration, which greatly reduces noise
- Rear gear chamber, high precision gear is used to shear gear, which provides stable operation and further reduces mechanical noise
- Multiple injection technology to reduce combustion noise significantly
Ultra-low fuel consumption
- Minimum fuel consumption 181 g/(kW•h)
- The low-speed fuel consumption area covers the typical conditions of trucks 950-1450r/min, making it more fuel-efficient
Powerful
- A smaller rear axle ratio can be selected while maintaining power, further reducing fuel consumption
Adaptable
- Power loss at 2800 meters above sea level, ultra-low power loss at 4500 meters of typical operating conditions
- Starting zero at -20°C in low temperature environment failed
