Some experts analyzed that the implementation of the Guosan Standard on July 1 will have profound implications for the upgrading of the entire heavy-duty automotive industry technology platform. However, due to the current unevenness in the ability of domestic heavy-duty truck companies to master the core technological capabilities, the product has caused major differences. The national triple card does not meet the user's expectations, and fuel saving is still one of the main concerns of the users.
On September 1st, a second-generation national triple card known as the “new legend of fuel economy†was successfully released at Shaanxi Auto, again causing a strong market response.
Shaanxi Auto continues to write a new fuel-saving legend
In recent years, international oil prices have risen steadily and domestic oil prices have skyrocketed, which has brought tremendous pressure on users to continuously increase operating costs. In early 2006, Shaanxi Automobile was the first to introduce the first fuel-efficient heavy truck in the automotive industry, saving up to 10-15%, causing a sensation in the automotive industry, setting off a heavy truck market in Shaanxi and Jiangxi 06, 07. Fuel-efficient spokesperson.
Since the country’s triple-cards entered the market in 2005, users have felt the confusion caused by problems such as rising operating costs, especially since the country’s implementation. Experts have raised many questions about the fuel-efficient nature of certain countries’ technologies. Many efforts and attempts have been made. In order to further increase user benefits, Shaanxi Auto has joined forces with members of the gold industry chain to conduct a large number of continuous trials, improvements, and enhancements to its national triple-card technology. On the one hand, it has fully inherited the advantages of the first-generation national triple card, and on the other hand, it has subdivided the product line. The advanced technology focused on the optimization of the fuel system and the optimization and matching of the entire vehicle. It has created a new generation of super fuel-efficient heavy trucks - Shaanxi Auto's second-generation triple card, and has continued to write a new legend for Shaanxi's fuel economy.
The fuel-saving advantage of Shaanxi Auto's second-generation triple card is that it has an original three-level conversion function, that is, to improve the economic efficiency of the entire vehicle and increase the revenue under various requirements such as no-load, light-load, full-load, etc. Using data and a large amount of experimental data, continuously upgrading the engine computer control program to the seventh edition, so that the vehicle's low fuel consumption area can work more widely, and the fuel consumption per 100 kilometers can be reduced by about 4 liters; the low-speed output torque of the whole vehicle increases, and the start is more sturdy and dynamic. More powerful, low-speed acceleration performance is further enhanced; vehicle electronic control function is greatly enhanced, with sensitive fault diagnosis, GPS satellite positioning and other functions, the user can fully understand all the "trend" of the vehicle in the cab; application of German BOSCH (Bosch ) The latest generation of high pressure common rail electronic control system and ECU electronic control unit enables the precise control of fuel injection to milligrams. The newly designed combustion system and intake and exhaust system make the combustion more complete, the emission is more environmentally friendly, and the fuel consumption is lower; The work area of ​​the Assemblage, Fast Transmission, Hande Axle, etc., is in line with the engine's economic zone, which makes the vehicle efficient and effective. Consumption.
According to Li Tianzhou, vice president of Shaanxi Auto Automobile Research Institute, “The domestic three countries' technologies are still in the initial stage, and each company’s products are different due to inconsistent technical standards, and the degree of difficulty in upgrading the technology is not uniform. The national triple card is established on the foundation of one generation and achieves a variety of technological breakthroughs, of which fuel saving is the brightest point. Electronically controlled high pressure common rail technology is a key factor for technological breakthrough. At present, only the software upgrade has reached the 7th edition. And the optimized matching of each assembly ensures that the vehicle works in a low fuel consumption area and maximizes the value of the user."
Users are amazed: The cost of vehicles is greatly reduced
According to statistical data, the stability of heavy-duty vehicles with electronically controlled high-pressure common rail technology is 60% higher than that of mechanical ones. In other words, the heavy-duty common rail technology can reduce the maintenance rate of heavy-duty trucks by 60%.
From the analysis of the three major assemblies of Shaanxi Auto's second-generation triple card, users can get unexpected surprises. First, Weichai engine parts have reached 85% of the total, have a good inheritance, the same shape and structure, maintenance rate decreased by 65%, the cost will be greatly reduced; in addition, the vehicle engine once replaced the oil, fuel Filter and oil filter is not higher than 1,000 yuan, but the maintenance cycle is extended 1-2 times, and the maintenance cost is even lower. Secondly, the transmission is equipped with 9-speed, 12-speed box and double countershaft structure. Large torque transmission, minimal torque loss, high stability, low maintenance cost and convenience; Third, Hande Axle adopts MAN technology single-stage bridge or double bridge, or Steyr Bridge, Hande for country three Market demand, further optimize the main gears in the bridge, increase the strength by 15%, and increase the transmission efficiency and stability by 10%. The optimized matching between the assemblies can enable the components to perform their best performance and reduce energy consumption.
In the three months that Ding Xingfu of Shanxi Datong user tried it, these performances felt very deep. He introduced: “In the course of several months of use, I feel the most obvious is the fuel saving, about 4% of the country’s two provinces, compared with peers. The country’s three-car hundred kilometers can save nearly 30 yuan, the more software upgrades, the more obvious the feeling, now has been upgraded 3 times, to the 7th edition. In addition, under full load, no-load, etc., the whole vehicle startup performance is very good The power is obviously increased to adapt to the harsh operating environment of coal; the overall performance of this vehicle is more stable, and there is no problem in the course of use. In addition to the routine maintenance, it has never been to the service station. The operating cost can save about 3,800 yuan, which is equivalent to the salary of a driver."
According to the actual use of the user Ding Xingfu, we make a user revenue model: According to the tractor four hundred liters of fuel, the average mileage per year is 200,000 kilometers, the average price of oil is calculated at 6.1 yuan per liter, and the fuel consumption is only one. The maximum one-year savings for the user is approximately: 4 liters/100 km X 200,000 km X6.1 yuan/litre=48,800 yuan. This number is undoubtedly impressive for the user.
