FOTON AUV has precisely identified industry trends and launched the 12-meter intercity coach BJ6122 equipped with the new generation A-series engine from Cummins, an internationally renowned brand. This not only meets the demand for high-quality coach products in the tourism market but also marks FOTON AUV's injection of strong momentum into the industry through technological innovation, driving the high-quality development of the tourist transportation sector.
Power Increased by 8%:
Powerful Performance Enables Efficient Operations
The star product, FOTON AUV BJ6122, is equipped with the new generation A-series engine from Cummins. Leveraging mature power products from trucks, it creates an independent gold power chain for coaches. With its excellent power performance, it brings users an unprecedented power experience.
Compared with engines of the same displacement, its acceleration capability is improved by over 8%, and its climbing ability is enhanced by over 10%. Even on complex road conditions, the vehicle can maintain stable power output, avoiding the jerkiness caused by insufficient power and providing passengers with a smoother and more fluid riding experience.
Furthermore, the Cummins engine boasts a maximum horsepower of 490PS, with leading power per liter and strong plateau adaptability, maintaining torque at altitudes up to 3,500 meters. This feature allows the BJ6122 to maintain powerful power output in plateau regions, ensuring the stability and reliability of the vehicle under plateau road conditions. For passenger transport companies, powerful performance not only brings higher operational efficiency but also reduces delays and additional costs caused by insufficient power, effectively supporting efficient operations for customers.
Fuel Consumption Saved by 2 Liters per 100 Kilometers:
Better Economy Reduces Operational Costs
In terms of fuel consumption, the Cummins engine also performs exceptionally well. Equipped with the new generation A-series engine from Cummins, based on the FFA design concept and coach operating conditions, it adopts the new HOLSET N7 turbocharging system, dual-flow dual-bypass technology to improve transient response and reduce fuel consumption; Alder Shot shaft seals to enhance oil sealing capability; and adopts new nano-filtration technology to reduce fuel pump power loss and improve fuel consumption.
Under the same operating conditions, the Cummins engine consumes over 1.1 liters less fuel per 100 kilometers compared to competing engines in the same horsepower range. Assuming a fuel savings of 2 liters per 100 kilometers, if a coach travels 100,000 kilometers annually and diesel costs 7 yuan per liter, the annual fuel cost savings alone would be 14,000 yuan, contributing to cost reduction and efficiency improvement.
Meanwhile, the non-EGR design and advanced thermal management technology enable the engine to better adapt to fuels of different qualities, further enhancing fuel economy. Additionally, the lightweight design of the Cummins engine also improves fuel economy. With a dry weight of only 796kg, the engine is 3% lighter than competitors, which not only reduces the overall vehicle weight but also decreases fuel consumption. For passenger transport companies, lower fuel consumption not only reduces operational costs but also increases vehicle operating mileage, supporting efficient operations for users.
In practical applications, the FOTON AUV BJ6122 intercity coach, equipped with the Cummins engine, has demonstrated significant cost-saving effects. For example, the BJ6122U8BJB model, equipped with the Cummins A10 engine, achieves cost savings of 22,000 yuan, a power increase of 3%, and a fuel consumption reduction of 6%. The BJ6122U7BJB model, equipped with the Cummins A8 engine, achieves even higher cost savings of 29,500 yuan, a power increase of 7%, and a fuel consumption reduction of 9%, showcasing its operational strength in cost reduction and efficiency improvement and setting a new value benchmark in the intercity passenger transportation market.
B10 Life of 1.2 Million Kilometers:
Reliability and Durability Enhance Customer Operational Efficiency
The Cummins engine also excels in maintenance and lifespan. The Cummins engine equipped in the BJ6122 has a maximum oil change interval of 100,000 kilometers and a B10 lifespan of 1.2 million kilometers, equivalent to circling the Earth 30 times. At the same time, the Cummins engine adopts a non-EGR design, advanced intelligent thermal management technology, and mature DPF service technology, ensuring stable operation of the engine under various operating conditions.
