Inventory development of key components of internal combustion engines: pump, post-processing, cylinder liner piston rings

As a high-tech industry with both capital-intensive and technology-intensive features, internal combustion engines and key components are inextricably linked to technological progress and market expansion. Not long ago, at the Secretary-General meeting of the national internal combustion engine industry, the Secretary-General of each sub-sector introduced the development of their respective fields.


In 2010, along with the development of China's automobile industry and construction machinery industry, the cooling water pump and oil pump industry also ushered in a period of rapid development.

During the year, the total industrial output value of the pump industry (compared with statistics) reached the highest level in history, reaching 2.832 billion yuan, up 40.3% over 2009, and the growth rate reached the highest level in history. The growth rate of some enterprises reached nearly 70%; The overall industry efficiency achieved the highest level in history, achieving a total profit of 225 million yuan. The industry is booming both in production and sales, and the sales accounted for about 98% of the output value. The scale of industrial investment in technological transformation is large, and the company considers strategically sustainable long-term development; There are many varieties of new products developed, and each company is willing to invest in development, indicating that the industry has a certain capacity for sustainable development; the speed of foreign exchange earnings through exports means that some companies have the ability to enter the world market.

For the pump industry, the favorable conditions for the development of the industry in 2011 are: the development environment of the automotive industry, construction machinery, agricultural machinery, etc. has created a better space for the development of parts and components companies. At the same time, it has begun to be formed in the industry. Obvious advantages of small-scale enterprises. Some of the company's products have been matched with international OEMs, and the market expansion space has expanded, while the cheap resources and labor advantages still exist in the short term.

The problem of survival in the development of the pump industry is also obvious. For example, the overall profit of the industry is low, accounting for only 6%-7% of the output value, and some dominant companies only account for about 10%. They cannot rely on profit for continuous investment; Inadequate senior technical talents, few companies with the ability to develop new products synchronously with OEMs, few senior technicians, low overall skill levels of employees, lack of masters who play the leading role, extensive management, lack of high-level modern management talents, low level of technological equipment, and quality Poor assurance ability; Because it is a small parts industry, government support is small; information is not working, unreasonable, slow to reflect, energy saving, environmental protection, and high-quality product types are few, unable to compete with the world's advanced enterprises.

From the perspective of market, foreign Spare Parts companies have established several joint ventures or wholly-owned enterprises in the country. With their advantages in technology, capital, and management, they are eyeing the Chinese market. In the near future, they will rob the market with large companies. It is the market for high-end products. The competition among domestic companies has resulted in lower product prices and worse corporate profitability, affecting the company's investment in development and sustainable development.

Therefore, although the pump industry is currently developing well on the surface by taking advantage of the large environment, in the long run, it is also on the thin ice. There are many barriers. As long as the general environment changes slightly, there are many companies that can hardly support and survive in the slits. .

Opportunities are still highly related to the development of the internal combustion engine and even the main engine production in the pump industry. On the one hand, due to the state's support for the reconstruction of water conservancy projects, construction machinery has a very good prospect of development. At the same time, due to the improvement of the national income and the improvement of the consumption structure, the number of individuals purchasing cars has rapidly increased in recent years. Therefore, the car industry has a tendency of continuous development. With the rapid increase of vehicles, the required cooling water pumps and oil pump accessories will also increase substantially. On the other hand, urban congestion control and cancellation of low-emission automobile purchase tax have affected the sales of some vehicles in the first half of the year. Raw material price increases will affect manufacturing costs. The earthquake in Japan will affect the car production of Japanese companies and create conditions for other companies to increase production.

The branch of the pump industry predicts that the increase in domestic cars will be around 15% in 2011, the increase in construction machinery will be more than 25%, and the total volume of pumps and oil pumps will be 50 million to 55 million sets, 15% more than in 2010. ~20% will temporarily benefit the development of the industry.

Development direction The person in charge of the branch of the pump industry pointed out that the future development direction of the industry lies in the following points. First, adjust the product structure, improve the technical level of products, develop new energy-saving and environmentally friendly products, and form their own core products and core technologies. Second, the formation of oil pump, pump spare parts production industry cluster, to the cluster, the direction of development. Third, with the development of the industry and the emergence of new technologies, we will enter new components and expand new markets. Fourth, increase investment in process equipment, improve the level of process manufacturing, and form its own core process technology. V. Opening up the international market, gradually forming its own product advantages in the international market. 6. The integration of informatization and industrialization shall be well done in the industry to improve the management level of the enterprise. VII. Actively seek financing for listing and solve the problem of investing funds.


Foreign capital still dominates In 2010, of the 4.3 million commercial vehicles sold in the market, 2.83 million were trucks. Most of the heavy-duty vehicles adopt the common rail or SARS route to meet the National III emission standards, and basically do not use post-processing.

Among the 2.83 million trucks, about 1.8 million light vehicles use the mechanical pump + electronic control + EGR and other methods to achieve the country's three emission standards. About 400,000 light vehicles using EGR (Exhaust Gas Recirculation) are used, of which Wuxi Longsheng 140,000 accounts for 35%, Yibin Tianruida 30%, and the other approximately 35%. Among the light vehicles, about 240,000 cars with the National Three Emission Standards were reached with mechanical pumps + DOC (oxidative catalytic converters) (+EGR), of which Weifu Lida accounted for 150,000 for 50%.

The catalyst industry is still dominated by foreign-funded enterprises in the Chinese market, with a market share of 73.4%, and the own-brand catalyst market share of only 26.6%. The domestic post-processing enterprises accounted for about 62% of the market for self-owned brand models (including crossover models).
Why foreign catalysts dominate China's catalyst market? First of all, all of the catalysts for the joint venture brand passenger cars were occupied by foreign catalyst companies, and we have not yet entered. Second, foreign catalyst companies have obvious technological advantages. They have started R&D since the 1970s. We are in the mid to late 1990s. Thirdly, all major foreign catalyst companies have set up factories in China to make full use of the Chinese labor force. The cost has been greatly reduced and our price advantage no longer exists.

The development of the internal combustion engine's emission post-processing industry closely follows the development of the automotive and internal combustion engine industries. In particular, the enforcement of emission regulations has a decisive influence on the development of the post-discharge treatment industry.

With the emission regulations being upgraded from State One to State Three, post-disposal equipment manufacturers have experienced rapid development. Taking Lida’s sales revenue as an example, it was only 10 million to 20 million in 2000 and 1.1 billion in 2010. yuan.

All the well-known catalyst companies abroad have made great inroads into China. For instance, Johnson Catalyst, BASF, Umicore and other foreign catalyst companies all set up factories in China to seize the Chinese market.

During the 12th Five-Year Plan period, China's auto industry will continue to develop at a rapid rate, with an average annual growth rate of approximately 10% to 15%, and will reach 30 million by 2015. It is expected that the post-discharge treatment industry will also develop at the same speed. In particular, the three-way catalyst company for gasoline vehicles will develop simultaneously. Due to a variety of reasons, the National IV emission standard for diesel vehicles has been postponed. Therefore, the SCR (Selective Catalytic Reduction) system for heavy-duty diesel vehicles that meet the four emission standards for diesel vehicles will be postponed. There is still much room for light vehicles to use EGR to meet the national emission standards.

POC (Particle Oxidation Catalytic Converter) + DOC technology also has good prospects for applications in light vehicles. It is expected that there will be more room for development in the national emission standards for China in the past one to two years and in the future.

Cylinder liner ring

Significant achievements in the Eleventh Five-Year Plan In 2010, the number of cylinder liners in the country was about 500, of which more than 30 companies were engaged in OEM support, and other companies basically served the aftermarket. The total assets of the industry are about 26 billion yuan.

During the Eleventh Five-Year Period, especially in 2010, the degree of concentration of the industry further increased. Basically formed piston rings are represented by Anqing Dibergs, Yizheng Shuanghuan, and Nanjing Feiyan; cylinder liners are represented by Zhongyuan Internal Distribution, Yangzhou Wuting Bridge and Zhaoqing Power Fittings; cylinder liners, pistons, piston rings, and friction subassemblies Shijiazhuang Jingang Group, Nanping Huayu Group, as well as leading companies in the industry listed companies such as Chengdu Yinhe Power and Zhongyuan Internal Distribution. These backbone enterprises have their own advantages and their product technology level is relatively high. Holding a high-end, high value-added product market, it takes up the priority of matching supply and continues to forge ahead in the aftermarket.

The economic aggregate has grown rapidly. Cylinder liner piston ring output value reached 11.9 billion yuan and 4.2 billion yuan, respectively, an increase of 30% and 35.5%; production reached 90 million and 1.02 billion, respectively, year-on-year growth of 30.4% and 20.83%.

Economic development has further increased. The sales revenue of cylinder liners and piston rings reached 12 billion yuan and 4.76 billion yuan, respectively, an increase of 34% and 40.61% year-on-year, respectively; the value-added ratio of the two products reached 26% and 38.27% respectively.

The income of employees increases with the increase in the economic efficiency of enterprises. Per capita income in 2010 was more than 7,000 yuan.

Technological transformation and technical measures have been intensified. The technical transformation project has achieved a virtuous circle of “planning a batch, storing a batch, and implementing a batch”. In 2010, the entire industry had an annual output value of over 50 million yuan, and the investment in technological transformation and technical measures reached 110 million yuan.

Strengthen product development efforts. More than 100 million yuan industrial enterprises have established their own R & D center, in the cylinder liner, piston ring surface treatment, material optimization, geometry and structure, the three major aspects of research and development and innovation.

Develop modular and modular production. The cylinder sleeve, piston ring and piston friction by-products are all optimized in terms of power and economy, so that the entire machine is assembled and the engine maintenance is quick and easy to use. Its overall use performance is increased by 25% to 30%.

The energy-saving and emission-reducing effects achieved remarkable results, and energy consumption per 10,000 yuan decreased by 1.7% year-on-year.

Leaders of the company led the development of Shijiazhuang Jingang Group Co., Ltd. with the goal of “crossing the scale, standardizing management, and improving the team”. In 2010, we optimized the product mix, increased the investment in technological innovation, and used advanced technology to increase the production capacity of high-value-added products. The company’s scale was up 70 percent year-on-year. %, the fastest growing industry. Central Plains is equipped with a July 26, 2010 listing at the Shenzhen Stock Exchange. It issued 23.5 million shares and raised more than 500 million yuan. It has created huge room for the company to leapfrog. The output of cylinder liners has increased by 32.5% year-on-year to more than 29 million. . Anqing Huanxin Group adopts advanced technology to improve the quality of products, so that the value-added rate of products can be increased to 56.94%. Yizheng Shuanghuan Piston Ring Co., Ltd. focuses on product development. In 2010, the total industrial output value increased by 40.62%. Nanjing Feiyan Piston Ring Co., Ltd. is market-oriented and its output value in 2010 increased by 33.8% and 22.5% respectively.

In 2011, it is expected to increase by 15% to 20%. In 2011, the internal and external environment of the entire industry was uncertain and varied. With the evolution of the financial crisis in various countries in the world, the international form is more complicated. The Middle East and North Africa have a chaotic situation. Japan's earthquake, tsunami and nuclear radiation all affected the changes in the global economic structure. The domestic host market peaked late and peaked at a low level. The first quarter was worse than in previous years. The low output of mainframes and excess production capacity of parts and components have resulted in increased competition in the aftermarket market. The appreciation of the renminbi is affecting the export business.

It is expected that the growth rate of cylinder liners and piston rings will be lower in 2011, and the increase will be between 15% and 20% in 2010. The cylinder liner output was between 103.5 million and 110 million, and the piston ring was 1.17 billion-1.12 million.

Product design and development will focus on product design and experimental capabilities. Companies need to improve product design capabilities, enter the product design and development stage of the market, and enter the synchronization phase with the host plant.

Modular design and manufacturing of products will be the common goal of the host and component industries. This will also promote multi-product production, and may also lead to cross-cutting, infiltration and integration among companies in the industry.

The concentration of enterprises has been continuously improved, and the situation of weak, small and scattered has been gradually improved. In response to this situation, relevant responsible persons pointed out that we should do a good job in two aspects. First, we must do a good job of energy-saving and emission reduction, promote the transformation of development methods, and vigorously develop high-value-added products to expand its proportion in the total volume. We will vigorously promote the application of new technologies, new products, and new materials such as energy-saving, water-saving, and material-saving materials. At the same time, vigorously promote circular economy, tap potential and improve efficiency. The second is to take the leading role of the leading companies, actively carry out benchmarking activities with leading enterprises, manage them, and provide technical benefits, and do a good job in scale management.
