Sinotruk Howo |Deciphering the China National Heavy Duty Truck Yellow River Hydrogen combustion engine traction train
With a single refueling distance of 4,871.18 kilometers, the Yellow River X7 of SINOTRUK set the Guinness World Record for “the longest single refueling distance of a semi-trailer truck”.
At the 2024 Commercial Vehicle Exhibition in Hanover, Germany, China National Heavy Duty Truck (CNHTC) exhibited the newly upgraded Yellow River hydrogen combustion engine tractor train. The innovative streamlined design with the hydrogen combustion engine realizes the perfect combination of ultra-low wind resistance and zero-carbon emission, and the wind resistance coefficient is reduced to 0.286, which breaks through the limit of commercial heavy-duty trucks in terms of low wind resistance and enhances the energy-saving effect of the vehicle by 15 percent, which fully demonstrates the cutting-edge scientific and technological strength of CNHTC and promotes the global commercial vehicle industry to move towards a greener and smarter environment. This fully demonstrates the cutting-edge technological strength of China National Heavy Duty Truck and promotes the global commercial vehicle industry to move forward to a greener, smarter and more efficient future.
Today, let's take a close look at the peak work of China National Heavy Duty Truck - Yellow River Hydrogen Combustion Engine Tractor Train!
Yellow River Hydrogen combustion engine ultra-low wind resistance tractor train adopts bionic design, the whole vehicle shape draws inspiration from water droplets, fish and other shapes in nature, and the cab and trailer of Yellow River Heavy Duty Truck are integrated, combining the “raindrop” body + “bionic fish back” shape of the trailer, the whole train is very powerful. With the combination of “raindrop” body and “bionic fish back”, the whole train is very streamlined, presenting the best aerodynamic shape and characteristics.
In terms of drag reduction details, hidden door handles and electronic mirrors are designed to minimize the projected area of the whole vehicle. When driving at high speed, the airflow around the car body passes smoothly, compressing the low-pressure area at the rear, and minimizing both viscous drag and positive pressure, ultimately achieving an ultra-low wind resistance coefficient of 0.286 for the entire train.

Ultra-low wind resistance coefficient
The wind resistance coefficient of the Yellow River Hydrogen internal combustion engine traction train is 0.286, while the wind resistance coefficient of medium and large SUVs is around 0.3. The wind resistance coefficient of a heavy truck is better than that of an SUV, which is far ahead of the whole heavy truck industry.
China National Heavy Duty Truck Corporation (CNHTC) started to invest in the R&D and design of low wind resistance heavy duty trucks as early as 2012, and created an aerodynamic simulation + R&D and design team consisting of more than 120 people. After more than 1,000 days and nights, the team has completed the R&D of ultra-low wind resistance trains and obtained more than 30 invention patents. In the process, the team conducted more than 500 rounds of high-precision CFD simulation optimization, went through 3 prototype iterations and 10 wind tunnel tests, and for the first time in the industry, the heavy truck was equipped with an active air intake grille, electronic mirrors, hidden door handles, and more than 20 types of airflow control accessories, which realized the extreme metamorphosis of the product of China National Heavy Duty Truck, and obtained the certifications of CTRC, Rheinland Technology, Editha and other domestic and international authorities.
Furthest Traveling Distance
Relying on the resource advantages of Shandong Heavy Industry Group, under the integration of high thermal efficiency power chain + low wind resistance train and many other fuel-saving technologies, the 2022 Yellow River series of vehicles created a Guinness World Record of 4871.18 kilometers of full single refueling.
In the application of more environmentally friendly hydrogen fuel technology, China National Heavy Duty Truck (CNHTC) has also invested a lot of R&D and design, and has achieved excellent results. It is the first time in the industry to successfully develop and commercially utilize the 15L large-displacement, high-powered hydrogen-fueled internal combustion engine, with a thermal efficiency as high as 45.03%, which is the first in the industry; in addition to the 2800L/70MPa high-pressure, high-capacity hydrogen storage system, which, together with the ultra-low gas consumption of the entire train, has a range of In addition, it is equipped with 2800L/70MPa high-pressure high-capacity hydrogen storage system, which, together with the ultra-low gas consumption of the whole train, has a range of up to 1100km, which fully meets the needs of long-distance trunk logistics transportation, and there is no more mileage anxiety.
In addition, China National Heavy Duty Truck Corporation (CNHTC) has developed a fully independent PCU intelligent control system for the whole vehicle, which can realize the whole scenario of energy management functions such as intelligent torque control, intelligent braking management, intelligent thermal management, etc., so as to let the vehicle run in the most fuel-saving and efficient state, and to realize the win-win situation of fuel saving and performance.
The launch of Yellow River Ultra Low Wind Resistance Heavy Truck will provide new ideas for energy saving and carbon reduction of commercial vehicles, bring new vitality to the transportation industry, and bring higher economic benefits to users.
Cab Design
In addition to the highly futuristic appearance and power, the cab of the Yellow River Hydrogen internal combustion engine traction train is equipped with a dual high-definition large screen for the intelligent cockpit. In addition, there are integrated precise voice capture interaction system, cell phone APP convenient control function, and also 360 around view, blind zone warning and other intelligent driving assistance functions, which further enhance the safety.
The cockpit adopts a front door opening design, giving full consideration to the driver's driving experience and optimizing the convenience of getting in and out of the car. There is also a star roof, NVH optimization, and simple top design, which can bring drivers a quieter and more spacious driving environment. In addition, the vehicle is also equipped with on-board refrigerator, inverter power supply, multifunctional table and other living facilities, folding under the sleeper, daily rest is easy and comfortable, providing a more intimate and convenient life services for long-distance drivers.
As the backbone of China's commercial vehicle industry, China National Heavy Duty Truck Corporation (CNHTC), with its profound technical accumulation and rich production experience, has set up more than 1,000 distribution outlets and 80 overseas offices worldwide, forming a marketing and service network covering the whole world, and perfectly integrating Chinese aesthetic essence with green technology, showing the world the charm of Made-in-China, and symbolizing that China's heavy trucks will play the role of a leader in the development of new energy sources for global commercial vehicles. It is a sign that China's heavy trucks will play a leading role in the development of new energy sources for commercial vehicles in the world.
