high reliability

The engine has a high degree of reinforcement, a large design margin, a maximum power of up to 700hp, and a maximum torque of 2300N. m
Accumulated over 45000 hours of bench testing and over 50 million kilometers of vehicle road testing
Lifespan exceeding 1.8 million kilometers/30000 hours

modular design

Components reduced by more than 30% compared to similar products - integrated fuel filter module, integrated design of coarse and fine filters
Integrated design of machine filter module, oil filtration, cooling, rotor filtration, and water filtration
Integral cylinder head, integrated intake pipe, compact design

lightweight design

The total weight of the machine is only 815kg (National V) - with powerful CAE analysis capabilities, optimized design is carried out while ensuring strength and reliability
Plastic and aluminum alloy materials are extensively used in positions such as flywheel housing, water pump, oil pan, rocker arm cover, and intake pipe

Excellent NVH performance

The rated power point has a noise level of less than 96dB (A) per meter, which is 2-3dB (A) lower than competitors. The body adopts a drum shaped skirt design, which has high strength, low vibration, and significantly reduces noise
Rear gear chamber, using high-precision gears on the shear gear for stable operation and further reducing mechanical noise
Multiple injection technology significantly reduces combustion noise

Ultra low fuel consumption

The minimum fuel consumption rate is 185g/kW • h, and the fuel consumption under common operating conditions is 3% -5% lower than that of competitors
The low-speed fuel consumption zone covers the common operating conditions of buses at 950-1450r/min, which is more fuel-efficient

Powerful

On the premise of ensuring power, a smaller rear axle speed ratio can be chosen to further reduce fuel consumption

Adaptable

At an altitude of 2800 meters, there is no power reduction, and at 4500 meters, there is ultra-low power loss under common operating conditions
Zero startup failure at -20 ℃ in low-temperature environment

Good adaptability

Small in size and light in weight, it is the ideal power source for 13.7-18-meter buses
The engine can be equipped with three generators in parallel to meet the electricity needs of various types of buses; The main air conditioning system is equipped with a structure that does not directly contact the vehicle frame, further enhancing the vehicle's NVH performance and improving overall quality
