Shaanxi Auto's second-generation triple card continues to write a new fuel-saving legend (Figure)

Shaanxi Auto Unveils Its Second-Generation National Triple Card With the implementation of the Guosan Standard on July 1, experts believe it will significantly influence the evolution of heavy-duty vehicle technology. However, due to the uneven development of domestic heavy truck manufacturers in mastering core technologies, there are still significant differences in product performance. Many users find that the current national triple cards fall short of their expectations, particularly in fuel efficiency, which remains a top concern for many. On September 1st, Shaanxi Auto introduced its second-generation national triple card, dubbed the “new legend of fuel economy,” and it quickly made waves in the market. This new model is not just another upgrade—it's a major step forward in the company’s long-standing commitment to energy efficiency and innovation. In recent years, with rising global oil prices and increasing operating costs, the need for fuel-efficient trucks has never been greater. In 2006, Shaanxi Auto was among the first to introduce a fuel-efficient heavy truck, achieving a 10–15% improvement in fuel economy. This breakthrough created a buzz in the industry and helped drive the 2006–2007 heavy truck boom in Shaanxi and Jiangxi. Since the introduction of the national triple card in 2005, users have faced challenges such as rising operational costs and inconsistent performance. Experts have raised concerns about the effectiveness of some technologies. To address these issues and maximize user benefits, Shaanxi Auto collaborated with industry leaders to conduct extensive research, testing, and improvements. The result is the second-generation national triple card—a powerful, fuel-efficient heavy truck designed to meet diverse needs. The key feature of this new model is its three-level conversion function, which enhances overall vehicle efficiency under various conditions like empty, light, and full load. Through continuous software upgrades, including the seventh edition of the engine control program, the vehicle now operates in a wider low-fuel-consumption range, reducing fuel consumption by about 4 liters per 100 kilometers. The low-speed torque has also increased, improving acceleration and stability, especially in tough environments like coal transport. Additionally, the vehicle comes equipped with advanced electronic control systems, including sensitive fault diagnosis and GPS tracking, giving drivers real-time insights into vehicle performance. The integration of the latest Bosch high-pressure common rail system and ECU ensures precise fuel injection, leading to more complete combustion, lower emissions, and better fuel economy. According to Li Tianzhou, vice president of Shaanxi Auto’s Research Institute, the second-generation triple card represents a significant technological leap. With the adoption of electronically controlled high-pressure common rail technology, the vehicle can operate more efficiently, maximizing user value while maintaining reliability. Users are impressed with the cost savings and improved performance. For example, Ding Xingfu from Datong, Shanxi, reported a 4% improvement in fuel efficiency compared to older models. He noted that after three software updates, the fuel savings became even more noticeable. Additionally, the vehicle’s power and stability under full load make it well-suited for harsh conditions. From a maintenance perspective, the use of Weichai engine parts, 9- and 12-speed transmissions, and MAN and Steyr axle technologies reduces maintenance costs and increases reliability. According to Ding, his annual fuel savings alone could reach nearly 48,800 yuan, making a significant impact on operating costs. In summary, Shaanxi Auto’s second-generation triple card is not only a technological milestone but also a game-changer for users seeking efficiency, reliability, and cost savings. It continues to set new standards in the heavy-duty truck industry.
