From November 11 to 13, the 2022 China International Internal Combustion Engine and Power Equipment Expo was held in Changsha. Quanchai has unveiled its non-road National IV engine, National VI engine, hydrogen fuel cell , electric forklift gearbox and parts products, showing the industry the extraordinary charm of Quanchai's diversified development and innovation-driven development to the industry in an all-round way. During this period, Mr. Ding Weili, vice chairman of Quanchai Power, was busy with interviews with the media, and conducted in-depth interpretation of the market status, development trends, and Quanchai's innovative genes of non-road National IV and new energy.
Non-road National IV new products have attracted attention and have accumulated achievements in the leading position for many years
On December 1, 2022, my country will officially implement the non-road National IV emission standard . The holding of the Sports Expo coincides with the eve of the implementation of the standards, and the venue is generally very concerned about non-road National IV products. In terms of non-road National IV new products, Quanchai has exhibited two powerful cooperation and benchmarked against international brands - V36 and V12 engines. The two engines are crowded with people and have become a popular "check-in spot" in the exhibition hall!
V36 engine is a new platform developed by Quanchai and Austrian AVL company for Harvest Machinery. It has the characteristics of strong power, low fuel consumption, long life, strong climate and terrain adaptability, low vibration and low noise. In response to the power economy issues that users are concerned about, the V36 engine adopts the high-pressure common rail fuel system, high-efficiency supercharger and DLC coating technology, which greatly improves the maximum torque of the engine and provides sufficient power in various environments. In terms of fuel consumption, Quandai, based on the large amount of user data collected, reduces the fuel consumption of commonly used working conditions and saves 12% of competitors compared with competitors, and pioneers the forward and reverse function of harvester fan to improve user operation experience.
V12 engine is a product jointly developed by Quanchai and Tiannei. The products are benchmarked against brands such as Yangma, Kubota , and are mainly aimed at the small excavator and rice transplanter market. The cylinder block, cylinder head , crankshaft , piston , and connecting rods are analyzed by CAE, and the cooling system is calculated by CFD, effectively ensuring the reliability of the engine body and having good NVH performance. In terms of engine performance, the common rail system and direct injection combustion chamber are used to reduce fuel consumption and improve product life.
Quanchai's V36 and V12 engines and two-valve structure provide important R&D ideas for engine companies in the industry. Therefore, not only cooperative companies and users pay great attention, but peer companies are also continuing to track the dynamics of Quanchai's new engines. Behind the technological breakthrough and product leading the market is Quanchai’s unremitting pursuit and investment in innovation and research and development for decades.
Take the upcoming non-road National IV emission standards for non-road National IV emission standards as an example. For engine companies, the implementation of National IV is both an opportunity and a challenge. Ding Weili, vice chairman of Quanchai Power, said that with decades of technical accumulation in the engine field and strong support from listed companies, the National IV regulations are an opportunity for Quanchai to expand and lead the market. Quanchai is one of the earliest enterprises in China to develop non-road National IV projects. On the one hand, Quanchai's rich experience and mature technology in light truck National VI engines can be learned from non-road engine development; on the other hand, Quanchai has been deeply engaged in the field of non-road power for many years. At the same time, through cooperation with domestic and foreign technology companies such as AVL, Ricardo, Bosch , Tiannei Suo, etc., it has introduced today's advanced technology, and has made a qualitative leap in fuel saving, power and reliability compared to the previous generation of products. Moreover, the support of listed companies can allow Quanchai to carry out research and development and post-stage experiments without worries.
At present, Quanchai Fei Road National IV engine supporting business can account for 30% of the company's business segment. The main cooperative OEMs in the agricultural installation sector include Levo , Wode, Doitz , Doyc , Yingxuan and other companies. The cooperative OEMs in the construction machinery sector include Heli, Shanghai Longgong, Zoomlion Heavy Industry, Shandong Mingyu and other companies, and will reach cooperation with more companies in the future.
hydrogen fuel cell has attracted attention and cooperated with partners to fully deploy new energy
With the promotion of national policies and the bursting of market demand, new energy is becoming an important development trend of power enterprises. At the exhibition site, Quanchai exhibited a hydrogen fuel cell that represents Quanchai's technical level and has a leading position in the industry.
According to reports, Quanchai has successfully developed an enhanced proton exchange membrane in the field of hydrogen fuel cells to achieve import substitution. Enhanced proton exchange membrane structure: both sides are perfluorosulfonic acid ionomer layers, and the ePTFE layer in the middle of the membrane provides additional mechanical strength. The pores of the ePTFE layer are filled with perfluorosulfonic acid ionomer to establish a continuous proton transmission channel, and inhibit swelling in the direction of the membrane plane. This is crucial to reduce the mechanical stress caused by the dry/wet cycle during the operation of proton exchange membrane fuel cell , and its service life is greatly improved compared with the same thickness of non-reinforced membrane.
At present, due to the incomplete construction of hydrogen energy infrastructure, the costs of hydrogen production, transportation, and hydrogen refueling are too high, hydrogen power has not developed to a large scale in China. On the one hand, Quanchai continues to increase research and development in hydrogen power directions such as hydrogen engines and hydrogen fuel cells, and on the other hand, it works with cooperative enterprises to make arrangements in multiple new energy branch directions such as commercial vehicle range extension directions, gas engine directions, gasoline and diesel 48V hybrid directions, and methanol engines.
Ding said that Quanchai's layout positioning in new energy products is "a limited attempt to track new energy." It is unknown where the country will ultimately position in the direction of new energy . Quanchai must make a comprehensive layout to match the progress of power research and development with the progress requirements of the OEM, and do not miss or fall behind in any direction. The extended-range project will be used as a transitional product between traditional energy and new energy in the near future, occupying the application scenarios of small and medium-sized horsepower segment power. In the long run, hydrogen engines or hydrogen fuel cells will become the real clean energy source of the future.
Lean management Create benefits, and make progress together to strengthen the momentum of upstream and downstream Industrial chain
Yuyou succeed, and you will not give up your achievements. In recent years, whether in the field of roads or non-road power, Quanchai's engine production and sales have always ranked among the forefront of the industry. It also won the 5th Anhui Provincial Government Quality Award in 2021. Behind a series of fruitful results, Quanchai's lean management model is inseparable.
In 2016, Quanchai officially introduced lean management into enterprises, including the management of the entire process of technology, production, sales, procurement, etc. Lean management mainly revolves around one thing - eliminating waste and improving efficiency. Through lean management, the concepts of all employees such as workers, teams, middle-level, and senior executives have changed. Everyone performed their duties and cooperated efficiently, achieving a huge breakthrough in reducing the number of production personnel by 30%, but increasing output by 50%. Lean management allows all data to be cloud-based, and all systems can be checked by parts inventory, company internal inventory, and market inventory. ERP controls costs (inventory), how much is missing, how much money is used to purchase, and not much capital is occupied on inventory.
At present, Quanchai has realized the automatic production line of , , with stable processes and mature technical workers. It only needs to ensure the stability of the quality of parts to ensure the stability of the factory equipment. In terms of quality assurance, Quanchai provides assistance and certification for its supporting enterprises. Regardless of the progress, cleanliness, material and appearance of parts, they have put forward strict requirements. If they cannot meet, they can apply. Quanchai has a dedicated assistance team to help find problems in the accessories companies, and provide assistance to the entire process from production process to packaging and transportation. Quanchai and suppliers make progress together to make the industrial chain stronger and stronger.
Ding said that the industry competition is fierce and cruel, but we must face it positively and continuously develop products in combination with the market. Whether in the field of traditional power non-road National IV, Road National VI, or new energy power, Quanchai has always adhered to the cornerstone of development of technological innovation, and continued to explore more advanced, green and inclusive development routes, bringing more and better solutions to China Power .
