A new pattern of supporting diesel engine system
Under the principle of "a large number of high-end models with a main vehicle system, a large number of ordinary models supporting the system", China's diesel engine market is brewing to form a new supporting structure. With the increasingly fierce competition in the commercial vehicle market in China, the commercial vehicle industry has entered a new stage in its understanding of supporting power. Vehicle companies increasingly see that without their own motivation, they will not have the core competitiveness of the entire vehicle, but through the management of the engine plant within the system and the external supporting control (take an 8~9L diesel engine as an example. The price is higher than the 0.85 to 12,000 yuan in the system, which will weaken the competitiveness of the other party in terms of price. It is an effective means to influence the competitors and even the entire industry. Based on this view, vehicle manufacturers generally have very strict development planning and control methods for heavy-duty and high-end light-duty diesel engines (vehicles) with high technological content. On the contrary, the power supply package for their low-end light vehicles is more open. On the whole, the most active supporting companies in the cross-system diesel engine industry in China are mainly classified into the following three categories: First, companies with significant overcapacity in the entire vehicle system; Second, some companies in the system are in a delicate position, forcing the engine plant to develop supporting external equipment. Survival; Third, low-end light diesel engines. With the large-scale deployment of light trucks to the depth market and the arrival of a new round of heavy-duty engine joint ventures, the original diesel engine supporting system in China is brewing to build a new pattern. Diesel engine cross-system matching market characteristics From figures 1, 2, and 3, it can be seen that although there is a generally stable proportional relationship between the number of diesel engines supporting the system and the total sales volume, after April and May of this year, the amount of supporting equipment outside the system has increased substantially, and the total sales volume of the industry has increased. Obviously approaching. According to calculations, the average power per unit of the cross-system diesel engine is 7 to 10 kW lower than the average power of each diesel engine in the total sales. This proves from another aspect that the cross-system diesel engines are mainly concentrated in mid- and low-end power stage medium-sized and light diesel engines. From the quarter-on-quarter growth percentage, in January, February and March of 2009, the external supply of the system was higher than the chain-to-quarter growth of the total sales, which confirmed that a large number of diesel engine manufacturers installed at the beginning of this year was for supporting the system. It is not required by the OEMs in their own system, and the installed type is mainly supporting light trucks, micro-cards, agricultural vehicles, and low-speed trucks. After February, the overall diesel engine market declined, and the chain growth rate outside the system was dragged down by this and dropped sharply. The year-on-year growth rate has basically risen since May, and the growth rate has exceeded the average of the industry. This shows that the diesel engine market this year depends to a certain extent on the number of supporting systems outside the system. Since the summer, light vehicles have been affected by the policies of the countryside, etc. Sales have increased, but most of the light trucks in the countryside are low-end models. The main supporting diesel engine is basically an independent diesel engine plant, with the exception of Liberated Xichai (CA4DW, CA4DX series) and North Korea. Diesel (CY4100, CY4102 series), Yuchai (YC4108, YC4110 series) have good performance, but outside Dongfeng Cummins , Jiangling, Qingling and other systems are not much. As can be seen from Figure 4 and 5, the past few years, the overall trend is characterized by cross-system sales of diesel and diesel market in the match, but the industry concentration (percentage of total sales in the previous five companies accounted for sales of diesel engine industry is calculated), but in Gradually decreased, as can be seen from the subdivided data, the main reason is: In the past few years, heavy-duty diesel engines as a centralized representative of the core technology, the manufacturers are in fierce competition. However, in terms of light vehicles, the output is huge, the price is low, and the requirements for the advanced nature of the supporting power are lower. This makes light trucks a very diverse source of supporting power. Plus, a large number of light truck manufacturers do not have diesel plants in their own systems. (In the light truck industry, in addition to the major giants, many companies do not have large sales, and it is not worthwhile to establish their own diesel engine plant. This way, Yunnei, Quanchai, Laidong, Yangchai, Sida, Changchai, and Xinchai’s four cylinders The amount of machine support has soared.) It is precisely because many light vehicles are equipped with a large number of low-end diesel engines, which decentralizes the concentration of the entire industry. Specifically, with the exception of Yuchai , Xichai , and Weichai , the share of many major diesel engine plants ( Shangchai and Deutz FAW-Dachai) in the total sales volume of the industry is declining (see Figures 6 and 7). Cross-system support to achieve new breakthroughs Liberation and Dongfeng are more conservative for cross-system support than other companies, but their engine support has begun to increase. The liberation medium- and heavy-duty vehicles are respectively equipped with Xichai CA6DL, CA6DF, CA6DN, CA6DM, Dic Diesel CA6DE, BF6M1013, and Weichai WD615, WD12, and WP10N series diesel engines. Liberated light vehicles are produced in several factories, and their supporting diesel engine manufacturers are also numerous. In addition to the Xichai, Dachai, and engine subsidiaries within the Liberation System (the output is not large, mainly gasoline and natural gas engines), Yuchai and Yang Chai, Sida, Xinchai, Wanfeng, Xinguang Brilliance, Yangjue, etc. are all supporting it. After the FAW Hongta Yunnan product plan was reclaimed by FAW, the plant's CA1050K and other light trucks were fitted with Dongfeng Chaochai 's various models. Dongfeng heavy-duty vehicle owners with Dongfeng Cummins, Yuchai and Dongfeng Renault engine, and Dongfeng Liuzhou Motor Yuchai supporting more YC6M, YC6A, YC6L, Weichai WP10, WD12. Now, the matching quantities of FAW Xichai CA6DF2, FAW Dachai CA6DE and other models are also increasing. Beiqi Futian Heavy Vehicle Co., Ltd. has the largest installed capacity of Weichai WP10, SC9DK, SC8DK, Dongfeng Cummins B, L, C, ISDe, ISLe series, Xi'an Cummins ISM series, Yuchai 6J, 6M, 6A, Xichai 6DL. , 6DF and other diesel engines; light car is the main distribution system outside the Xichai , Yuchai , Yangchai, Yunnei, Dachai, Quanchai, Yang moving, Lai Dong, Chao Chai and other plant diesel production. Futian's diesel engine plant Tianjin Lovol and Beijing Environmental Protection Power, due to the relationship between production capacity and adaptable models, the amount of support is not much. In particular, Foton's accelerating development towards the high and low ends has reduced its supporting space for Beijing's environmental protection power in the system. The plant is approaching a number of light truck manufacturers to try to support more auto factories outside the Futian system. Shaanxi Automobile is currently equipped with Weichai WP10, WD615 series and Xi'an Cummins ISM series, but also with the system outside the diesel, Shanghai Hino models. China National Heavy Duty Truck Co., Ltd. is mainly equipped with engines of Hangfa and Zhongqi Plants of Qiqiu. At the same time, it also supports the Shangchai and Shanghai Hino models outside the system. Baotou Beiben Heavy Duty Truck dominates Weichai, followed by Huachai, Yuchai, and Mercedes-Benz. SAIC Iveco Hongyan mainly uses Weichai and Yuchai outside the system. The amount of Shangchai's equipment in the system is not large, and the Phillips Red Cursor has only just started supporting its lion models. However, the company has recently made major adjustments to the future direction of development, expanding the scope of product cooperation from light passenger vehicles and heavy trucks to large and medium-sized passenger vehicles, special vehicles and core components and other fields. The demand for diesel engines will certainly be more diversified, and the proportion of procurement outside the system will increase significantly. JAC heavy trucks are mainly based on Weichai, and lighter types are self-produced 4JB1, Dongfeng Chaochai and Yuchai, followed by Xichai, Yangchai and Quanchai engines. Diesel engine supporting system will establish a new pattern For diesel engines, especially heavy-duty engines, all vehicle manufacturers want to have their own products. For this reason, since 2008, a new wave of diesel engine introductions has started. It is worth noting that the important feature of this wave of joint ventures is that it cooperates with most of the major foreign automakers in China, and both import and produce foreign mainstream diesel products, such as Mercedes-Benz and Foton, Mann and Sinotruk, and Caterpillar. Le and Jianghuai, Fiat and SAIC Iveco and Chongqing Heavy Duty Truck Group, as well as rumored Volvo cooperation with the liberation, Dongfeng. In addition to the previous Xi'an Cummins, Dongfeng Renault, Shanghai Hino and so on. The commissioning of these diesel engines will shake the original supporting market pattern. Statistics show that in the 11L and above displacement models, Weichai will not have absolute market dominance. In 2009, the average monthly sales of the Weichai 12L III standard diesel engine WP12 was less than 300 units, and the average monthly sales of the Xichai 11L and 12L engine CA6DM/N reached 280 units, and the 11L diesel engine ISM of Xi'an Cummins was also close to this output. Renault 11L's DCI11 diesel engine has an average monthly sales of 540 units. In addition, Dongfeng Cummins 13L's ISZ series will be mass-produced, Yuchai 13L's YC6K will be on the market, and Shanghai Diesel's 12L diesel engine is being developed. In the field of 10L machines, Weifang Diesel's market share in the car is expected to decline by about 10% after three years. On the other hand, various OEMs such as China National Heavy Duty Truck, Jiangling, Great Wall, Qingling, etc. are encouraging the external diesel engine plant to support the system. In comparison, in the light-duty diesel engine market, the market is slightly concentrated mainly in high-end models. For example, the Fukuda Cummins ISF series is mainly equipped with Foton high-end light vehicles and export light trucks. Dongfeng Light Engine Co., Ltd. has also produced the ZD30 series 3L light diesel engine imported from Nissan, which is mainly equipped with light trucks and SUVs of Dongfeng and Dongfeng Ri brand products. In addition, such as Nanjing Iveco's Sophie, the Great Wall's INTEC, Chaochai's NGD3.0, Jiangling's VM, Ford models are also basically supporting the system. The supporting of these high-end light diesel engines is concentrated in the OEMs in the system because their output is relatively small. Cross-system support is still an important goal for them. Cummins has specialized agencies to conduct research on the high-end light truck market in the country to determine how much Cummins ISF product production should be. Once the market demand for high-end light trucks, this situation will certainly change. The production capacity of China's diesel engine factory is generally excessive, and external support is an inevitable choice. At the same time, the trend toward specialization of automobiles is becoming increasingly apparent, and the selection of engines will inevitably be more and more detailed. This trend is leading to a reduction in the purchase of single-type diesel engines. The types of diesel engines in the vehicle plant system are limited and cannot be fully met. Therefore, cross-system procurement (matching) is an intrinsic requirement regardless of the vehicle manufacturer or the diesel engine manufacturer. In addition, under a series of huge adjustment actions such as joint ventures and restructuring, the status of the main engine plant in the vehicle system has undergone subtle changes, and the parent company’s purchase volume has become increasingly unreliable, forcing them to strongly support external development in order to achieve their own development. . For example, Dongfeng Tianlong high-powered models increasingly rely on Dongfeng Renault's diesel engines. Dongfeng Cummins turned the market into a model for Dongfeng and other models of construction machinery, and established a special overseas business unit. Yutong, Jinlong, Zhongtong, etc. The restrictions on the liberation of Xichai are also decreasing. Apart from the research and development of the model for liberation and FAW cooperation, the models matching the system can be developed independently by Xichai. In terms of expanding the external market of the Group, Dongchao's Chaochai even jointly funded the establishment of an engine company with Anhui Jianghuai Automobile Co., Ltd., mainly in Jianghuai and South China, with a production capacity of 50,000 units. Dachai has also faced new challenges after becoming a joint venture company from a subsidiary of FAW. Dachai has positioned new development targets for construction machinery. The tremendous progress of Dongfeng Cummins, Dachai, and Tianjin Revo in the field of construction machinery has deeply touched Caterpillar's Chinese market, and the company is studying corresponding countermeasures. Cross-system supply will have a huge impact on the original supporting structure. In short, under the principle of "a large number of high-end models with the main distribution system vehicle, a large number of ordinary models supporting the system", China's diesel engine market is brewing to form a new supporting structure.
