high reliability

B10 lifespan reaches 800000 kilometers
The design and development are based on the concept of large displacement engines, and important components such as turbochargers, starters, and fuel systems are sourced from globally renowned suppliers
Endure the most rigorous and rigorous tests such as bench testing, three highs testing, and vehicle drum testing to ensure the reliability of key components

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

Excellent NVH performance

Low speed, low noise: rated speed of 3000r/min is lower than similar displacement competitors at 3600r/min
Common engine speed (1300-2000) r/min is lower than similar displacement competitors (1600-2400) r/min. Reduce engine speed, avoid high-frequency torsional vibration zone of the engine, and reduce engine noise by 2dB (A)
NVH is superior to competitors, and the acceleration external noise is 4dB lower than competitors (A)
Using a secondary balancing mechanism - reducing vibration intensity by 41%

Ultra low fuel consumption

The minimum fuel consumption rate is 199g/kW • h, which is 3-4 g/kW • h lower than competitors, and the fuel consumption per 100 kilometers is 1L lower than competitors
The optimal economic fuel consumption zone of the engine is close to the low-speed zone (1200-2100) r/min, with high mechanical efficiency
Low accessory power consumption, standard with ordinary silicone oil fan, 3% more fuel-efficient than traditional rigid fans
System optimization: Low speed, high torque, and low speed ratio rear axle effectively avoid high fuel consumption areas, while high torque reduces the driver's gear shifting frequency, effectively reducing fuel consumption

Powerful

Strong starting and acceleration capabilities: low-speed torque is 13% higher than competitors of the same horsepower
Strong climbing and overtaking ability: maximum torque 14% higher than competitors of the same horsepower

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

Comprehensive configuration, suitable for 6.6-9m school buses, 7-7.5m light passengers, and buses, meeting the structural and performance needs of different customers
The entire vehicle can be equipped with various accessories such as a generator, power steering pump, air conditioning compressor, air compressor, etc., enriching users' choices
