At the workshop hall of China National Heavy Duty Truck Group Jinan Power Co., Ltd., the company officially unveiled its latest fuel-saving innovation—the No.2 Fuel Economy Engine. This launch has sparked a growing trend in the industry, as more companies strive to meet the rising demand for energy-efficient solutions. The new engine is now being integrated into the Hao Li series and will soon be available across the entire product line.
Developed in collaboration with internationally recognized design institutes, the No.2 engine follows the European mechanical development program while being tailored for the unique conditions of Chinese road transport. After rigorous testing, including 6,000 hours of continuous operation, the engine achieved a minimum fuel consumption of 189g/kWh, meeting European standards. Field tests showed that vehicles equipped with this engine can reduce fuel consumption by over 10% per 100 kilometers compared to similar domestic models, while also increasing torque reserve by more than 30%.
Wang Donghui, Deputy Party Secretary of CNHTC, noted that with rising oil prices, many domestic automakers have introduced their own fuel-saving products. However, not all of them deliver real value, making it difficult for users to choose the right option. He emphasized that CNHTC's No.2 engine not only offers genuine fuel efficiency but also stands out in terms of performance nationwide.
Liu Wei, Director of the Technology Center at CNHTC, explained that the engine’s improved efficiency stems from key upgrades, such as the use of an 8500 fuel injection pump and a supercharger with a deflation valve, replacing the traditional common rail system. This optimization ensures a better match between the intake and fuel supply systems, significantly enhancing both power and fuel economy.
He added that the core component of the engine is the fuel pump. While other manufacturers use the 7100 model, which still results in high fuel consumption, CNHTC developed the 8500 pump specifically for Chinese heavy trucks. Testing has shown that the 8500 pump improves fuel economy by about 3g/kWh and increases torque reserve by 30%, providing stronger acceleration, climbing ability, and overload capacity.
Liu also shared a practical example: the No.2 engine costs about 500 yuan more than a standard engine, but it saves around 5 liters of fuel per 100 kilometers. For a vehicle traveling 150 km daily, this translates to a daily saving of 8 liters. At current fuel prices, this amounts to approximately 35 yuan saved per day, meaning the extra cost is recovered within a month.
In addition to the engine launch, CNHTC has seen impressive sales growth. From January to July this year, the company produced and sold 35,385 heavy trucks, a 39.12% increase compared to the same period last year. Its market share reached 20.37%, and revenue hit 12.767 billion yuan—a 77.4% rise. Profits and taxes amounted to 930 million yuan, up over 200 times, while exports increased to 4,764 units, generating 132 million USD, a ninefold increase.
