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 just 815kg - powerful CAE analysis capability, optimized design while maintaining strength and reliability
Plastic and aluminum alloy materials are used extensively in flywheel housing, water pump, oil pan, rocker arm cover, air intake pipe, etc

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 96ddB(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 181g/(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
