What will trucks look like in the future? Sinotruk has a new answer for the Hanover Auto Show
The Yellow River X7 has established a high-efficiency and low-consumption product base and market reputation for its economic and energy-saving characteristics since its birth. In April last year, the Yellow River X7 recorded a record of “4,871.18 km per tank (945.29 l)” in terms of fuel economy, creating a Guinness World Records of “The longest distance a semi-trailer can travel on a single refueling trip”, the wheel proves its intelligent fuel-saving performance and the advantages of efficient transportation. Recently, China Heavy Industry Corporation (Sinotruk) has unveiled its integrated Yellow River hydrogen internal combustion engine traction train at the Hanover Commercial Vehicle Show. What's the new car look like? Here's a sneak peek to see how awesome this Yellow River hydrogen internal combustion engine traction train really is.
The integrated design of main train and trailer is a remarkable feature of the Yellow River hydrogen internal combustion engine traction train. From the side to see, “Seamless convergence” of the main hanging integral natural, with the majestic landscape green painting, visual shock, spectacular! From the beginning to the end of the whole streamline modeling gives a kind of natural harmony of the United States.
In the integrated design of Main and trailer, the Yellow River hydrogen engine traction train combined with more than 20 kinds of pneumatic accessories, through parameter control and multi-objective collaborative optimization to obtain the best combination scheme, to achieve excellent overall shape of the aerodynamics and accurate local flow control effect. Using y“Bionics” design, using bionics“Fish back” and“Airfoil” drag reduction concept, with the extreme main suspension clearance, to maintain the curvature of the streamlined shape with the cab, to achieve the main suspension collaborative technology research breakthrough. Meanwhile, integrated deflector, lengthened side deflector, curved front end, rounded corners on both sides and top of the container, fish-back curve, tail deflector (to restrain trailing vortices and reduce the pressure difference between the front and rear of the train) and low rolling resistance tyre matching are all applied in the details of drag reduction technology, the ultra-low wind resistance and super-energy-saving of the hydrogen engine traction train can be achieved by minimizing the train resistance.
In addition to energy-saving advantages, the main-trailer integrated design of the Yellow River hydrogen engine traction train in the safety performance can not be underestimated. Because the integrated design of the main suspension achieves the main suspension cooperative braking, the continuous optimization matching strategy can effectively avoid the minor differences existing in the imperfect matching of the main suspension ABS and EBS, to avoid the increase of braking distance, vehicle head push, tail flick phenomenon, in the emergency braking process, the vehicle attitude more stable, effectively reduce the risk of skidding rollover. In addition, through the good data matching and data support of the tractor and trailer, the main vehicle and trailer can form a good communication and cooperative work, which will improve the performance of active and passive safety to the highest, put more weight on driving safety.
In reducing the details of wind resistance, the Yellow River hydrogen engine traction train is really a great effort. The first is the design of the active intake grille, which can open and close automatically according to the engine temperature demand under high-speed driving conditions, effectively reduce the cabin flow resistance. The second is the application of electronic rearview mirror, this new type of electronic rearview mirror can reduce the traditional rearview mirror due to the high-speed air around the fall off the periodic eddy caused by wind resistance and wind noise, and improve the visibility of rain driving.
The hidden door handle of the same model as the passenger car is exquisitely designed, smooth and silky. The outside surface of the door handle is skillfully combined with the door surface to avoid turbulence caused by local bulges, make the overall shape more unified while reducing the driving wind resistance. The main train of the Yellow River hydrogen internal combustion engine traction train optimizes the waist line shape and the blade angle of the air guide hood in detail, to ensure low wind resistance at the same time by suppressing the vortex around the wheel cavity, effectively avoid driving rainwater road body pollution, ensure that the body to maintain clean. At the same time, for the wiper wiper wiper wiper effect to improve to ensure the safety of driving in rainy days.
As we continue to talk about the“Wind resistance” of trucks, one might ask: is wind resistance really that important to trucks? The answer is yes: very important! Because the most obvious benefit of low wind resistance is energy saving, because the speed and wind resistance is proportional to the speed, the faster the greater the wind resistance, the more energy consumption. The test data showed that on the plain, at speeds above 80 km per hour, the vehicle's energy consumption increased by 4 litres for every 10 km increase in speed, while nearly 70% of the vehicle's energy consumption was used to deal with wind resistance, this shows the importance of wind resistance.
The Yellow River X7 has been known for its unique low wind resistance“Bullet” design since its initial public offering, when its wind resistance coefficient of 0.349 was the best. At the 2024 Hanover Motor Show, the Yellow River hydrogen engine traction train was optimized for extreme wind resistance, using “Raindrop” design inspiration and second-order continuity curve modeling theory, the bumper, the front face, the front window, the top cover, the top of the integrated design, so that the cab with water into a“Curve” into the aesthetic, while minimizing the wind resistance. Through science and technology to break through the body barrier, the application of active intake grille, electronic rearview mirror, hidden door handle and other active and passive pneumatic turbulence resistance reduction products, to achieve better resistance reduction... ... This series of innovative technology support, the Yellow River hydrogen engine traction train wind resistance coefficient as low as 0.286, once again shocking the world.
In addition to the efficient energy-saving brought about by the ultra-low wind resistance of the entire vehicle, there is also the green power configuration with zero carbon emissions, a Weichai WP15-H2-ICE hydrogen engine with thermal efficiency up to 45.03% is carried on the Yellow River hydrogen engine traction train. The engine produces 530 horsepower and 2,700 n. M's maximum torque, Matching & GT. 70mpa high-pressure carbon fiber hydrogen cylinder, can achieve 800 km long voyage, suitable for a variety of application scenarios, fully meet the needs of high-speed trunk logistics transportation of various complex working conditions.
Into the car, the oncoming is full of technical equipment console. All-liquid crystal instrument panel with large-scale multimedia display, the cab of the digital working environment armed very well. The multi-media display supports touch operation of radio, USB, navigation, Bluetooth, sinotruk intelligent communication, mobile phone interconnection, air conditioning and other functions, and close to the driver's operating table layout is very convenient and safe to use.
With the leading technical strength and unremitting innovation, for the industry to create a greener, more efficient, more comfortable, more energy-efficient logistics and transport equipment. Through the Yellow River hydrogen internal combustion engine traction train, we can fully feel China Sinotruk Extreme Science and technology innovation concept and ingenuity car-making spirit. As a highly efficient logistics transport vehicle combining cutting-edge technology and green ecological concepts, the Yellow River hydrogen internal combustion engine traction train will undoubtedly become the focus of the exhibition, to open a new attitude logistics transport green, efficient travel of the new chapter.
