Leading the way to innovation to fill multiple technological gaps
“ Xichai CA6DM3 State V diesel engine has solved key technical problems such as low fuel consumption, long life, and long oil change period while the product has reached the national five emission standards, and has obtained six inventions and 36 utility model patents, which have filled domestic heavy A number of technical blanks for diesel engines... "This is the identification of the China Five Engine New Product Appraisal and Scientific and Technological Achievement Appraisal Meeting held in Xichai by the Economic and Information Commission of Jiangsu Province and the China Machinery Industry Federation. Experts have given Xichai State five new products CA6DM3. Reviews. This time, Xichai's leading technology in the five series of products of the country has attracted the attention of industry professionals through the identification of scientific and technological achievements.

One step ahead of technology
If we say that in the past few years, people have focused on Xichai's focus on the stunting of the industry-leading fuel-saving technology, and today it is more about exploring why Xichai Aowei's five products are leading the market in selling technology. It is reported that at present, Xichai has formed Aowei, Hengwei, and Conway's full range of China's five products, with a displacement of 2 to 13 liters and a power of 60 to 500 hp; Xichai’s five-phase products have fully inherited the technological advantages of the original products and conducted The extension of innovation, especially the application of long-lived technology and long-term maintenance technology, has greatly improved the comprehensive fuel-saving capability, power performance and engine reliability of China Five's products, and has enabled Xichai to pull high-tech engine applications. Get it first.
In 2016, Xichai CA6DM2 V5 engine has achieved a market share of 11% in the 11L engine with its leading technology advantage, and its sales volume has ranked first in the industry for four consecutive years. It helped Jiefang heavy truck sales increase by 84.5% year-on-year and its market share exceeded. 30%, for the first time in a row, the country’s sales volume has been the highest in 12 months This year, the model is becoming the most popular heavy-duty engine for users. As long as it is equipped with the heavy truck of Aowei 11L Xikai, it will be "a hard to find a car!" It not only explains the quality of the heavy truck from a new perspective, but also harvests a large number of users. Highly recognized and praised.
The group of China Five diesel engines, such as CA6DM3, 6DM2, and 6DL3, which passed the identification of new products and scientific and technological achievements, independently developed a high-burden pressure engine structure and lightweight design, a low-particle distributed combustion system with an effective thermal efficiency of 45.5%, and a dedicated Four innovative technologies such as cam compression engine braking system, 100,000 km oil change technology, B10 life reliability technology, common rail fuel injection system electronic control unit (ECU) and gas flooding urea injection system, and the product meets the national five emission standards At the same time, it solved key technical problems such as low fuel consumption, long life, long oil change intervals, and obtained 6 inventions and 36 utility model patents, filling a number of technical gaps in domestic heavy-duty diesel engines. Among them, the life span of CA6DM3 and CA6DM2 five diesel engine B10 can reach 1.5 million kilometers, which further establishes the leading position of Xichai Aowei heavy-duty engine in the industry.

A step forward environmental upgrade
In the current situation where energy and environmental issues are increasingly prominent, how to adopt the new energy strategy to catch the green economy express train has brought unprecedented challenges and opportunities to the automobile and internal combustion engine industries. In recent years, Xichai has adopted scientific and rigorous design and verification, and has innovatively adopted a number of special technologies in the development of China's five gas engines. This has solved the industry's problems and significantly increased the reliability and economy of new energy products, and has gradually become an industry. A strong green sound.
The two natural gas engines, the 6SL2 and 4SL2, which were identified through new product appraisal and scientific and technological achievements, independently developed natural gas multi-point sequential electronic control injection systems, large-flow gas nozzles, high-efficiency lean combustion technology, high-energy ignition systems, and wear-resistance. The valve seat ring and other innovative technologies solve the technical problems of gas cylinder uniformity, high accuracy and high-responsive gas control, exhaust valve reliability, and long life of the natural gas engine; 4 invention patents and 10 practical applications have been obtained. New patents and 8 computer software copyrights.
After scientific and technological investigations, the use of autonomous electronically-controlled multi-point jet systems on domestic commercial vehicles to achieve the country's five emissions is an innovation. The successful development of the two natural gas engines has added two new members to the Xichai natural gas engine family. The engine horsepower segment has been extended from 170-420Ps down to 140Ps, enabling the Xichai natural gas engine to operate in the 140-420 power segment. The full range of coverage marks the first in a series of domestic and new energy truck engine engines matching the Xiceq natural gas engine. It also leads the development and manufacturing of new energy commercial vehicle engines in China with its high-end quality and leading technologies. development stage.
With green friendship, embracing the blue sky, and Xichai leading the road of innovation, the heart of environmental protection, the deep intentions, the hard work ... not only indicates that Xichai has entered the fast lane of a new round of technological development, but also indicates that Xican will breed the nation. Brand, the determination and strength to create high-end power.
Sequestering agent is an effective and versatile organic chelate, it can soften the water quality, such as Ca2 +, Mg2 +, Fe3 + metal ions have a strong chelat and scum dispersion force, prevent sediment generated in the process of dyeing and finishing and other dirt scum, equipment and will slowly dissolve and remove sediment silicon scale, calcium soap and oligomer, It can prevent metal salts from re-contaminating various fibers, improve the whiteness, brightness and color fastness of bleached, dyed and printed products, and prevent re-contaminating the white base of printed products and yarn-dyed products. Physical and chemical properties of chelating dispersant. Chelating dispersant plays a very important role in textile printing and dyeing industry.
