Car "Heart" Remanufacturing Engine Environmental Protection Utilization

Energy conservation and emission reduction are the driving forces

The energy crisis and environmental pollution have become more and more important for people in this era. The recovery, reuse, and remanufacturing of resources has become a subject that we have discussed and studied. On February 25, 2010, the National Development and Reform Commission and the State Administration of Industry and Commerce issued the "Circular on Enabling and Strengthening the Management of Marking Signs for Remanufactured Products of Auto Parts", and the "Notice" clarified the sign of remanufactured products for auto parts. , And confirmed and announced the list of pilot companies for the remanufacturing of auto parts. The publicity shows that the country's determination to standardize and guide the remanufacturing industry is also given to those qualified and capable manufacturers.

As we all know, in the entire automobile parts remanufacturing industry, the fields involved are very extensive. Engines, transmissions, motors, tires, etc., and China's auto parts remanufacturing has just started and is still in the stage of exploration. It is listed as There are only five kinds of engine parts and gearboxes for auto parts manufacturing, and only 14 pilot companies. This situation determines that there is a small gap between China and developed countries. Of course, we are full of confidence in the prospect of China's auto parts remanufacturing industry. From the view of only 14 pilot companies, the state has a high threshold for remanufacturing enterprises. "The process of selecting pilot enterprises is very strict," said Dr. Wenqen Liu, Division of Central Resources Development, National Development and Reform Commission. However, the temptation to do this market is too great, coupled with the domestic consumer's own consumption habits (low prices are preferred), resulting in a number of small workshops under the banner of remanufacturing to produce some cheap defective products. Black workshop. The word “refurbishment” has existed abroad for many years. The understanding of “refurbishing” by foreign consumers is also rational or neutral. First, because “refurbished” equipment or components are worth mentioning, they are very foreign. In a sound marketing environment, there are strict evaluation standards and a series of quality assurance measures for “refurbished” products. Second, companies engaged in this type of business are highly representative in the industry. Can be "refurbished" to come to China, it seems to lose the taste of neutral, and even bring a hint of "derogatory" color, plus some exaggerated reports of irresponsible media, "renovation" has become a word for a time The object of the expedition, which allows companies that are engaged in the remanufacturing of parts and components, has suffered a total loss. Talking about "refurbishing," everyone seems to have more choices than to talk about. With this list of government announcements, everyone has had some positive responses to this issue.

Personally think that because "refurbishment" was too "demonized" in the country, it made the government unify the industry's mark this time, and once again stressed the word "remanufacturing," perhaps because it is related to "refurbishing." Clear the boundaries. In the topic of retreaded tires that we had done not long ago, we have given everyone a detailed analysis of the status quo and difficulties of the tire retreading industry. It can be said that this represents the prevailing situation in the field of remanufacturing. A sentence sums up that "a rat has destroyed a whole pot of soup." Although it is a bit rough, it can explain the problem. We also hope that through such a topic, we can say fair words to those innocent businesses and those victims. Renamed for the remanufacturing industry, it can also play a role as a needle thread for the majority of consumers.

What can be remanufactured?

Some people have such doubts: After remanufacturing the engine and overhauling the old engine, is it not a concept? The reporter also specifically consulted the manager of the remanufacturing department of Dongfeng Cummins Engine Co., Ltd. Hu, he laughed that the engine remanufacturing is far different from the overhaul. This has always been the hope that the media will help clarify and distinguish. Engine remanufacturing has relatively strict standards in terms of equipment selection, factory inspection, etc. The most important is that the ultimate goal of engine remanufacturing is to perform a full factory performance restoration of the equipment—only the basic components of the equipment are retained, and the moving parts are all updated. And finally a process method that restores its manufacturing standards. Including the processing, detection and correction of defective holes, all the parts of the machine are restored to original size, and then the new moving parts are used for reassembly testing to achieve or basically meet the original machine standards. As a used equipment, it has higher quality and better performance. The overhaul is based on repairs. The technical measures taken to maintain its good technical condition and normal operation during the product use phase are often random, in-situ, and emergency. Remanufacturing is based on the replacement of moving parts and the new processing of basic parts. It is a different concept of "repair" and "change." Maintenance and remanufacturing also follow different principles for the replacement of parts. Overhaul pays more attention to correcting damaged parts. For example, the pin inside a part of the equipment should originally be a transitional fit, but may have become The scope of the clearance fit has been reached. At this time, remanufacturing is to solve the problem with replacement parts, while the overhaul is to restore the original transition coordination by installing gaskets and sleeves.

Specific to the engine remanufacturing field, compared to more than 20 years of operating experience abroad, it is not too long for China's engine remanufacturing to start. Therefore, the formulation and promulgation of various standards are still in progress. From the list of pilot companies announced in the “Notice”, it is not difficult to find that the companies selected are absolute core and leading enterprises in the related fields, such as the gearbox representative enterprises. Fast and engines include Cummins, Weichai, Yuchai, and other leading companies in the industry. Throughout the list, everyone will find that the NDRC's accreditation of pilot companies' qualifications is based on the following three points: 1. To be representative of the industry, the brand In itself, it is a guarantee of quality. Selected companies rank among the top in terms of sales volume, reputation, etc.; 2. Must have strong technical strength, in other words, use certain intellectual property rights, which is also a hard indicator. Dongfeng Cummins, Weichai, Jinan Fuqiang Power and Yuchai have all witnessed rapid development in recent years. In addition to consolidating their own markets and customers, they have also introduced new technologies and products from time to time to meet the changing needs of customers; The third point mentioned below leads to a good sense of customer service and the ability to establish service specifications that are customer-oriented. These three points generally constitute a threshold for entry into the remanufacturing industry. This filters policy. The loss of a large number of workshop-style factories, to a large extent, avoids the confusion of fish. The pilot enterprises for formal remanufacturing are also an affirmation and encouragement.

Industry people have something to say

According to Hu, the head of the Dongfeng Cummins Engine Remanufacturing department, the engine was remanufactured using the old engine as a "blank." In strict accordance with the technical requirements, special technologies and equipment were used to dismantle and clean the old engine, and the six engines were available. The main parts are reworked and all the rest are replaced. The general process flow is: dismantling → cleaning → repair processing → assembly → factory test → spray packaging process. For example, the diameter of the cylinder bore will become larger after the engine block wears, and the corresponding piston increases in the remanufacturing process. The main performance of the engine can be completely consistent with the new engine. After the repaired parts are assembled and tested, the main performance must meet the new engine standards before they are allowed to leave the factory. From the appearance, the rebuilt engine and the new engine are no different, and even the after-sales service and claim conditions are exactly the same as the new machine, such as enjoying 1 year free warranty treatment, but the price only accounts for 50% to 20% off the new engine. In the selection of “blanks”, there are also very strict standards. The old machines that must be recycled must be original products and the peripherals are complete. For example, the cylinder can not be cracked, and the large part is worn instead of damaged. In the brand selection of remanufactured machines, the current manufacturers still rely on their own products. In order to get the old machines from other homes, they must have their own manufacturers. Authorization can be done, and not just what the average person understands as long as they have industry qualifications. Because each manufacturer's own technical standards and product specifications are different, it is difficult to guarantee the quality of remanufactured products. Manager Hu also stated that in addition to providing a better development environment for these pilot enterprises in the policy, related industry standards and regulations and regulations are also being further formulated and improved, and it is estimated that they will soon be introduced. The development of the manufacturing industry is a good opportunity. The market size of the remanufacturing industry is actually far greater than what we have seen. As long as the chaos and chaos in the current market have been contained to a certain extent, it will certainly have very good prospects. This point has already been verified abroad.

According to Xie Jianjun, head of Jinan Fu Qiang Power Co., Ltd., Fu Qiang Power has five complete production lines, and now has an annual capacity of 15,000 remanufactured engines and 50,000 sets of engine parts. Developed a wide range of surface engineering technologies such as nano-spraying, nano-brush plating, high-speed arc spraying, micro-pulse cold welding, and stick-coating with independent intellectual property rights, and the remanufactured rate of used parts was increased from 73% in the world to 90%. , reached the international advanced level. At present, Fuqiang has formed more than 20 varieties of remanufactured products including Steyr, Cummins, Daichai 6110, Chaochao 61O2, Santana, Audi, Jetta, Mitsubishi and Cherokee.

Yu Ping, Chairman of the Board of Yuchai Machinery Group Co., Ltd., gave a clear introduction to the issue of body mining, which is generally concerned by the collective interview of “Remanufacturing and Sustainable Development of the Automotive Industry”: “Recycling is indeed an important link. From the recycling of engine parts, we recently signed a cooperation agreement with Caterpillar in the United States. Actually, we and Caterpillar are also very difficult during the negotiations, but it is optimistic about our most important network. I have more than 2,000 in the country. Home service system, hundreds of companies specializing in spare parts, all in my place, when the car has a problem and belongs to my engine, it is checked and replaced by my service station, and parts are replaced. Hou, all this information and these resources are actually controlled in the network of our manufacturing companies.We can successfully negotiate with such a powerful company as Caterpillar globally. Apart from the fact that the country must now vigorously develop the remanufacturing industry, it is optimistic about the outside of the Chinese market. , I think it is very important to us. It must rely on one China and it is very powerful. A company with a very strong network, or else, relying on one family to recycle this part is very inefficient."

Through interviews with relevant stakeholders in some pilot companies, in addition to a new understanding of what is happening in engine remanufacturing, the company’s full confidence in the dry remanufacturing industry is also felt in everyone’s speech. We also look forward to the introduction of relevant standards and regulations as soon as possible so that the remanufacturing industry including the engine can enter a period of rapid development as soon as possible.

Domestic engine remanufacturing events

China National Heavy Duty Truck Group Jinan Fuqiang Power Co., Ltd. was established in 1995 by China National Heavy-duty Truck Group Co., Ltd. and British Lister Petter Company. It is the first domestic automobile engine remanufacturing company and is currently the only member of PERA, the only North American engine revamping association in China. . This background also made Jinan Fuqiang a natural candidate for the first batch of pilot companies.

On December 14, 2009, Caterpillar (China) Investment Co., Ltd. and Guangxi Yuchai Machinery Co., Ltd. (Yuchai) signed an agreement to establish a joint venture company for Yuchai diesel engines and components and parts of Caterpillar diesel engines. And parts provide remanufacturing services. “We look forward to sharing Caterpillar's expertise in remanufacturing with Yuchai to provide customers with sustainable, lower-cost solutions that will ultimately serve the purpose of developing this new market.” Caterpillar, who is responsible for the remanufacturing business President Steve Fisher said that “while benefiting the environment, the platform created by the new company will provide more green jobs and technologies.” Yu Jie, deputy general manager of Yuchai Machinery Co., Ltd. responsible for remanufacturing, said: “We hope to adopt Caterpillar's cooperation in remanufacturing achieves the company's new development goals, and we are confident that we can provide more value-added services to our customers and meet the pressing development needs of society and the environment."

Future prospects

In 2009, China’s auto sales reached 14 million, making it the world’s largest auto market with more than 60 million vehicles. This provides a huge market for the remanufacturing of auto parts. The amount of scrapped cars should be calculated by multiplying the car ownership by 7%. China's calculation standard is slightly lower than that of developed countries. The car ownership should be scrapped by the amount of car ownership multiplied by 6%. Then, the number of cars scrapped in 2010 in China should be more than 3.6 million. This figure will also steadily increase. The number of cars scrapped each year may be around 4 million. According to this trend, if China can use 30% of scrapped vehicles for remanufacturing each year, the average annual sales volume can reach 36 billion yuan, the added value can be recovered by 49 billion yuan, and 180,000 workers can be employed to reduce the amount of carbon dioxide emissions. 2.3 million tons. The important feature of remanufactured products is that the quality and performance meet or exceed the new ones, but the cost is only 50% of new products, energy saving is 60%, and material saving is 70%. The aluminum material of the engine cylinder block material is used as an example to produce the same aluminum material and recycled aluminum. The energy consumed is less than 3% of primary aluminum, and pollutant emissions are reduced by 97% compared to the production of primary aluminum. According to conservative calculations, the replacement of remanufactured engines for 10,000 vehicles will save 647 tons of steel and save 1.9 million kWh compared with the replacement of engines. Industry insiders expect that only one remanufacturing of auto parts will have a market size of more than 20 billion yuan in 2015. With the support of the government, the remanufacturing market for other products will be even more substantial.

Foreign remanufacturing development

The remanufacturing of spare parts has been developed in foreign countries for more than 50 years. A relatively complete manufacturing and service system has been formed. In Munich, Germany, BMW has built a specialized recycling and lending center to study the dismantling and remanufacturing of used cars. During the remanufacturing process, 94% of scrapped auto parts were repaired by high-tech, 5.5% recycled, and only 0.5% were landfilled. At present, developed countries such as the United States, France, etc., auto parts remanufacturing almost cover all kinds of products on automobiles, and the remanufacturing rate can reach over 95%.

news

On May 31, 2010, 11 departments including the National Development and Reform Commission issued relevant documents on the scope of the pilot project to expand the remanufacturing of auto parts. The document indicates that China will focus on the remanufacturing of parts such as automobile engines, transmissions, and generators, and will expand the pilot range of auto parts remanufacturing to drive shafts, oil pumps, and water pumps. At the same time, it promoted the remanufacturing of construction machinery and machine tools, and the renovation of large-scale waste tires.
