After five years of efforts, China National Heavy Duty Truck Group has possessed two types of state-III emission engines: “Electric Control Common Rail†and “Electrically Controlled EGR Systemâ€. This indicates that CNHTC has fully prepared for the National III standard.
“If the country is now to implement the National III emission standards for the heavy truck industry, I'm sure that China's heavy truck is the most prepared company in this industry.†In October last year, China's heavy truck Group Secretary and Chairman Ma Chunji had confidence To the "car man" said such a sentence.
Nine months later, with the advent of the National III emission limit on July 1, all commercial vehicle companies are faced with the triple challenge of the clearance of a large number of China II vehicles, the breakthrough of the national III technical bottleneck, and the substantial increase in the cost of digestion. At this time, Ma Chunji can finally prove what he had originally said, and his confidence comes from China National Heavy Duty Truck's newly developed EGR WD615 State III diesel engine.
Of course, for China National Heavy Duty Truck, this is not just to respond to the implementation of national emission standards, as Ma Chunji said: "In the eyes of China National Heavy Duty Truck, this is to improve the ability of independent innovation, enhance the quality of enterprises, strengthen scientific management, and enhance The driving force for competitive strength is to realize the important measures that are in line with international standards as soon as possible, and it is also a rare opportunity for development. It is also an inevitable requirement for building a resource-saving and environment-friendly society.†In order to achieve a breakthrough in emission technologies, China National Heavy Duty Truck is It has taken a full five years to overcome such a long-term plan, it is not difficult to understand why Ma Chunji was so full-hearted.
As early as 2002, when China was still implementing the national I emission standard, Sinotruk cooperated with RICARDO and TNO in the Netherlands and successfully developed the method to fully meet the national III emission regulations and approached without additional treatment. National IV emission limit high-pressure common-rail country III engine; In 2005, China National Heavy Duty Truck completed all vehicle calibration and various assessment tests and preparation of production capacity, and its fuel consumption, emissions, noise and reliability and other technical indicators It is basically in line with the international advanced level. The engine adopts the most advanced second-generation electronically-controlled high-pressure common rail fuel injection system of Japan Denso. In 2005, it completed the calibration of all vehicles and various types of assessment tests and mass production capacity preparations. It has accepted customer orders since 2006. About 5,000 vehicles of State III were put into the market.
In order to further improve the company's core competitiveness and independent innovation capabilities and reduce industrial risks in the automotive industry, at the end of 2005, China National Heavy Duty Truck Technology Development Center organized China National Heavy Duty Trucks Chongqing Fuel Injection System Co., Ltd., which took the first time in one and a half years to successfully complete the ownership in China. The use of electronically controlled inline pump fuel injection system and cooling of electronically controlled EGR (exhaust gas recirculation) technology to meet the emission requirements of the National III diesel engine, which is currently the only domestic use of EGR technology of the National III diesel engine. After more than two years of hard work, the EGR engine has completed the transition from technology research and development, bench testing, road testing to mass production, and has now reached the monthly production capacity of 10,000 units.
At this point, China National Heavy Duty Truck has already possessed two types of technology, the "Electric Control Common Rail" and "Electrically Controlled EGR System", which are the National III emission series engines. "On July 1st, the state fully implemented the diesel engine III standard, and we have already occupied market opportunities. I believe that after EGR production, this trend can be more clearly reflected," said an insider of China National Heavy Duty Truck.
Competitive differentiation
When CNHTC's electronically controlled EGR system was officially launched and mass production was reported, it undoubtedly cast a “blockbuster†in the Chinese heavy truck industry. The major commercial vehicle forums and related websites revolved around China’s heavy weight. The discussions and evaluations of steam and EGR are also beginning to “popularizeâ€.
After all, EGR has not been adopted by any domestic company before China National Heavy Duty Truck used it to switch from State II to State III. In developed countries, except for the use of EGR by a few manufacturers such as MAN and SCANIA, high pressure common rails are the mainstream of emission upgrades, and they are also recognized by the industry as the most promising technologies for diesel engines. Although EGR and high-pressure common rails were all adopted in the implementation of Euro III, when the Euro III to Euro IV was upgraded, the high-pressure common rail technology had more room for technological upgrading than the EGR alone.
At present, the most critical fuel injection system technology for high pressure common rail is basically monopolized by multinational corporations. In addition to imports, only those like Bosch, Delphi and Denso can be developed in China. The giants, in order to achieve the national III emission standards, almost all domestic commercial vehicle companies have adopted the introduction of foreign technologies and selected the common rail technology platform. This has enabled multinational corporations to form an electronically controlled common rail system seller market in China. Because of technological weaknesses, the power to speak in cooperation with multinational parts and components companies is relatively weak, and there is basically no room for bargaining during negotiations. "The forced implementation of State III emissions, due to the monopoly of technology, does not rule out that multinational companies use electronic control of the oil supply system in short supply, and increase the price to domestic companies. In this case, the price attached to each vehicle will be no less than 20,000 to 30,000 yuan." China National Heavy Duty Truck dealers said so.
With the only national III diesel engine that adopts EGR technology in China, China National Heavy Duty Trucks has embarked on a differentiated competitive path and has voiced its voice in the technology areas that have been “controlled†by multinational corporations. But the emergence of any new kind of thing is a challenge to the traditional concept. Naturally, the industry's doubts about whether Chongqing Heavy-Gas EGR can truly achieve the National III emission standard began to appear, and even some of its competitors have also made negative comments on it.
Real data is believed to have the best persuasive power. Shenzhen Hager Jieshun Transportation Co., Ltd. purchased 15 heavy-duty truck EGR III vehicles and used them for a period of time to compare fuel consumption with other models. They found that the HOWO with an EGR engine has a fuel consumption of only 29 to 31 liters per 100 kilometers, which is 10 liters lower than that of other countries III vehicles and 3 liters lower than the previous National II vehicles. This also means that drivers who drive the HOWO III will save at least 15,000 yuan per year in fuel costs compared to other drivers. "Now, our drivers are eager to open HOWO vehicles. In order to create better economic benefits for the company, but also In order to deliver on the promise to the driver, the company signed a contract for the purchase of 20 HOWO vehicles equipped with EGR engines in early June, said General Manager of Hager Jieshun.
Although it is now entering the off-season sales season, according to the sales staff of Sinotruk Sales Department, from June 19 to June 20, a total of 553 orders for EGR were accepted for two days, indicating that as the National III emission regulations approached, users no longer With the wait-and-see attitude of the third car, the market began to rebound. Industry experts also analyzed: “At present, international crude oil prices continue to rise, and domestic diesel supply continues to be tight. Under the dual factor, costs will make users more sensitive because heavy trucks are originally a production tool rather than a consumer product. Heavy truck EGR is actually In the market where the common rail technology is monopolized, let them have another possible choice."
It is understood that through cooperation with MAN, Scania, and Bosch, China National Heavy Duty Truck Co., Ltd., after introducing and absorbing core technologies, finally developed the III EGR engine. Its technical basis is undoubtedly, due to its full autonomy. Property rights, so the technology can also effectively reduce the industrial risk of domestic heavy trucks; Second, because most of the parts are developed by heavy truck, each EGR engine is about ten thousand yuan less than common-rail engines, which has obvious Third, the national III EGR engine's fuel economy, oil adaptability, and ease of maintenance, has been recognized by the previous customers, and quickly spread through word of mouth to attract more and more users; Fourth, and transnational The development of enterprises in China, China's heavy truck production capacity is not limited, has invested nearly 100 million yuan to purchase a dedicated production equipment, forming a mass production capacity. Flexible production based on order requirements...
In the implementation of the National III emission standards, import alone is far from meeting the large domestic matching requirements. The increase in the cost of technology upgrades is not something that users are willing to accept.
China National Heavy Duty Truck EGR Engine has taken the lead in the market, and the current response and admiration caused by the user group is believed to be unacceptable to other competitors because of the disputes between the state-of-the-art technology of EGR and high pressure common rail. At least in the short term, they will squeeze their market share. The sales of heavy-duty trucks equipped with expensive high-pressure common-rail engines are not optimistic.
As a heavy-duty dealer said: "Users will not control how advanced you are in implementing State III technology. They value cost, power, and reliability. Because of foreign technology monopolies, they need to import parts and common-rail engines. The cost is too high. More importantly, the common-rail engine must require high-quality diesel, but now China's diesel quality is almost not up to the national III standard, and it is easy to cause damage to the engine, but heavy-duty EGR engine oil The product only needs to meet the national II standard, so I am optimistic about its future development."
“Our EGR took the lead in meeting the requirements of the National Development and Reform Commission for the State III engine. We have passed quality verification and national announcements to achieve the same emission reduction effect. The price is still more than 10,000 yuan less than a common-rail engine. Why do users not use it?†China National Heavy Duty Truck Party Committee Deputy Secretary Wang Donghui said, "It is undeniable that there are still some users who are skeptical of domestic technology, and even more common with the electric engine technology common rail engine, so we must also ensure that they provide suitable products. However, we are currently It will also mainly use EGR technology to compete for the market share of State III heavy trucks, not to say that common rail technology is not good, but EGR is more suitable for China's national conditions."
Fully prepared to switch
Although the market outlook is optimistic, now China’s heavy-duty trucks are still at the critical moment of completing the full-year mission.
From January to May, China's heavy truck was in good condition in the first half of the year. 63,000 heavy-duty trucks were sold and sold, an increase of 45% year-on-year, and sales revenue was 22.6 billion yuan, a year-on-year increase of 59.3%. Each of the indicators hit a new record in history, achieving double production and sales ahead of schedule one month ahead of schedule, creating sales and sales exceeding 15,000 for consecutive months. The new history of the vehicle. However, it must be realized that due to the imminent implementation of the National III standard, the early release of the national II heavy truck sales volume in the first half of the year and the advance “overdraft†is one of the important contributing factors. In particular, after entering the month of June, the task of digesting inventory country II products will become even more important. Urgent, otherwise it will not be able to successfully achieve the overall volume of the National III product arrangements.
At the mid-year sales meeting in 2008, Ma Chunji made instructions for the second half of the year: “June is the key to the Group’s accomplishment of the annual task. It is an important month for all units to level up, catch up, find gaps, and implement measures. Seriously summing up the work from January to May and seeing opportunities for corporate development, unifying thinking, grasping opportunities, and focusing on completing the tasks of production and operations in June and the second half of the year."
According to the plan, China Heavy Vehicles will ensure the production and sales of 12,000 heavy-duty vehicles in June, so that production and sales will reach 75,000 units in the first half of the year, and the target of completing 60% of the annual tasks will remain unchanged. Of course, in this part of the planned sales, we believe that The II model will account for a large part.
This is only the first step in achieving the smooth transition of State II to State III, and it will actively prepare for the sale of State III models in the second half of the year. For China National Heavy Duty Truck, there are many tasks to be done, just as Wang Donghui told Autobot: "Our EGR engines do have many advantages, but after all, they are new products just entering the market, just like there are some users. We only recognize Denso and Bosch's products, so at this stage, our main task is to quickly launch a series of marketing activities around the country III, including product tour, business training, etc. We can't get up early, catch up on late sets, and let more More users know what our EGR engine can do for them.â€
Today, China National Heavy Duty Truck EGR products have first entered the markets of Beijing, Shanghai, and Guangzhou, which are ahead of the implementation of the National III standard, to achieve bulk sales. Active marketing in mainstream cities should quickly accumulate reputation for CNHTC's EGR.
The subsidiaries of China National Heavy Duty Truck Group are also focusing on related work, including joint distributor units, service stations through telephone, fax, home visits, etc., and communicate with end users, especially key users, to promote China to them in a timely manner. Heavy truck EGR country III engine advantages, and together with the sales network unit to do a good job of market research, timely understanding of market information, do a good job in the development of system users, large users, with the key conversion plant do a good job in the country III, especially EGR product development, Selection, announcements, etc., work together with various network entities to complete custom vehicle ordering, vehicle delivery, and payment collection.
As for the sales theme in the second half of the year, China National Heavy Duty Truck also revolved around the National III emission standard switching work to study the issue of fulfillment of sales policies, ensure that timely marketing policies are in place, perform service training in advance, and mobilize the enthusiasm of marketing and refitting units to the maximum.
At the same time, China National Heavy Duty Truck Corporation also established a separate file for the user branch company that selected the country III product, focusing on timely and effective after-sales service and parts supply. “We hope to solve the worries of the State III users and the domestic technology is also trustworthy. That's right," said Wang Donghui.
According to conservative estimates by industry experts, Heavy Gas's EGR III engine technology can be at least half a year ahead of competitors in the market. With the increasingly fierce competition in the domestic heavy truck market, for a new product, it has six months to one year. The time difference between the "uncontrolling the world", whether it is the cultivation of its market recognition or the establishment of a competitive advantage, is a rare opportunity. State III standards are enforceable, and China National Heavy Duty Truck is likely to occupy the industry opportunities with EGR engines. Even if other manufacturers want to launch EGR, they have fallen behind in time.
This is indeed the case. As early as three years ago, SINOCHEM began to tackle the technical problems of the EGR III engine. In the meantime, after a long process, only tens of thousands of experiments have been conducted, and the purchase of testing equipment has cost hundreds of millions. For other companies, in order to reach the current stage of heavy-duty trucks, the steps of research, experimentation, stereotypes, inspections, announcements, equipment entry, and commissioning of production lines must go one step at a time. To complete this series of procedures, it will take at least one year. This time will be the best opportunity for Sinotruk to increase its competitiveness and capture market share.
Smooth transition of the overall situation
Previously, some analysts estimated that due to the implementation of the National III standard, the price of heavy trucks will rise sharply, and Sinotruk's sales volume will decline sharply in the second half of the year, accounting for less than one-third of the annual sales.
However, such a situation may have less impact on China's heavy truck. Because according to the current order situation, it is estimated that sales in the first half of this year accounted for 60% of annual sales. In usual years, this proportion is usually 55%. This means that, compared with normal years, the implementation of State III standards, although the company's sales have been affected, but the decline is not very clear, China's heavy truck is expected to achieve a smooth transition. Ma Chunji also believes that this year's heavy-duty truck market as a whole shows a "saddle-type", and the demand in the first half of the year is hot, and it began to decline in June. After the implementation of the National III standard, there may be a short-term correction in the heavy truck market, but there will be no fundamental reversal in the total market demand.
Although the advance purchases brought about by the implementation of State III emissions have indeed stimulated sales in the first half of the year, fundamentally, the basic market demand remains strong. In particular, starting from May, coal, electricity, and oil transportation were generally strained throughout the country, and the logistics and transportation tasks were extremely arduous. This will have a major impact on the heavy truck market, bringing major business opportunities, while heavy truck EGR III products will have better market performance in the second half than competitors.
Great Wall Securities Lu Lei said that China National Heavy Duty Truck Group, China's heavy-duty truck industry leader, its performance and the overall market demand is closely related. Now the driving force of the heavy truck market comes from the expansion of the toll-by-weight range. Heavy trucks have a cost advantage in medium-to-long-haul freight transportation, which makes consumers who want to buy medium-sized cards turn to buy heavy trucks. With the recent simulation operation of some provincial trunk road tolls, the toll collection will be promoted to the trunk line, which is conducive to ensuring the new demand for heavy trucks.
In addition, the mileage of highways has increased year by year, and the life cycle of heavy trucks for 3 to 5 years will also boost the consumption growth of heavy trucks. He estimated that the heavy-duty truck industry will maintain an average annual growth rate of 8% to 15% in the next few years. It is not difficult for China National Heavy-duty Truck Corporation to maintain a 15% growth rate in the next few years.
As for the plans for engine emissions technology, China National Heavy Duty Truck Natural Co., Ltd. will strengthen the existing technologies and move forward to implement the national IV emission standards.
"Beijing has entered the State IV, China National Heavy Duty Truck IV is common rail plus EGR, and now we use EGR to lay the foundation for the next step." Said Cai Dong, General Manager of China National Heavy Duty Truck, which focuses on production technology.
