April 2010 Automobile Engine Production and Sales Entering a Steady Fast Track
In April, engine production and sales were in line with the entire vehicle: a year-on-year increase
Corresponding to the entire vehicle market, according to the statistics of the latest issue of "China's auto industry production and sales news," 55 automobile engine companies that had been included in the statistics in the first four months of 2010 completed production of 5.8226 million units and 5.941 million units respectively. , Compared with the same period in 2009, it increased by 64.61% and 66.61% respectively. However, in terms of the production and sales volume of vehicle engines for the month of April, there was a negative growth of 9.87% and 6.78% respectively from the previous quarter; despite this, there were still 34.33% and 29.94% growth compared with the April 2009 production and sales volume. rate. As with the overall automotive market, if we look at the monthly growth curve for 2010 compared to 2009, the overall trend for the rest of the year in 2010 will be a year-on-year decline in the year-on-year growth rate.
In terms of production volume, among the 55 vehicle engine companies in the first four months of 2010, Chongqing Chang'an, Guangxi Yuchai, SAIC-GM-Wuling, FAW-Volkswagen, Liuzhou Wuling Liuji, Shanghai GM Powertrain, Chery, Dongfeng Nissan Passenger Vehicles, FAW Group, Harbin Dongan Automobile Engines, Beijing Hyundai, Anhui Quanchai, Harbin Dongan Automobile Power, Shenlong and Shanghai Volkswagen ranked in the top 15 in terms of cumulative production. Compared with the first quarter, in addition to other minor changes, the ranking of Dongfeng Nissan passenger cars has increased significantly, and Shenlong Motors has returned to the top 15 list. In the first quarter, it entered the top 15 with super-high growth rates. Single Weichai Holdings was squeezed down.
In terms of market size, despite the fact that there has been no monthly average output of more than 100,000 units in April, the average monthly production of more than 50,000 units reached 9 companies, and the average monthly production reached 20,000 units in 27 companies. The number of companies with an average monthly output of more than 10,000 units was one more than that in January and the first quarter, which was 43 companies. This data reflects that although the pace of market progress has slowed after reaching the zenith of March, the degree of market activity has not decreased, and the number of companies with an average monthly output of more than 10,000 units is seen as a vehicle engine company. The production and sales volume is tending to be stable.
In terms of production concentration, the production concentration of the top five production enterprises is 24.56%, which is a decrease of 0.34 percentage points from the value in the first quarter of 2010; the production concentration of the top 12 companies is 48.73%, compared with 2010. In the first quarter of the year, it decreased by 0.56 percentage points. The divergence of production concentration indicates that the current auto market is still in an overall rising period. Everyone has money to earn, and there is still a considerable gap between the industry and the stages when companies enter relatively lean production and compete for product technology.
Increase ratio to slow down the production and sales stability of diesel engine
For diesel engines, in the first four months of 2010, the 24 diesel engine companies included in the statistics completed 1,422,200 units and 1,460,800 units respectively, an increase of 39.37% and 46.18% respectively compared with the same period of the previous year. Specifically, the number of enterprises with diesel engine production exceeding 10,000 units in mid-month is the same as that in January and January 2010. The rank order of the 11 companies by production volume is: Guangxi Yuchai, FAW Group, Anhui Quanchai, Weichai Holdings, Kunming Yunnei, Dongfeng Chaochai, China National Heavy Duty Truck, Dongfeng, Jiangxi Jiangling, Yangchai and Shandong Lay move. In addition to minor changes in rankings, the main diesel engine manufacturers are relatively stable.
Compared with the increase in the growth rate of heavy-duty diesel engine companies in the first quarter, Weichai Holdings is a typical indicator of the cumulative increase in production volume over the same period of last year. This indicator has dropped more, falling from 213.34% in the first quarter to April. 111.77% of the time. Except for Weichai, the year-on-year cumulative increase (average monthly output of more than 5,000 units, cumulative year-on-year increase of over 50%) also includes Great Wall Motor (159.29%), Dongfeng (153.28%), and Qingling (91.76%). ), Jiangling (60.87%), Dongfeng Chaochai (55.97%) and China National Heavy Duty Truck (55.25%). Although other companies have seen up to 40% year-on-year growth, they are dwarfed by the above companies and are not listed here. In addition, Kunming Yunnei (-13.13%) is still the only negative growth in the cumulative year-on-year growth of higher-yield companies.
April negative growth in gasoline engine and passenger car market keep pace with the development
For the gasoline engine used in gasoline engines, the 42 gasoline engine companies included in the statistics for the first four months of 2010 completed 4,397,700 units and 4,487,500 unit sales respectively, an increase of 74.89% and 74.61% respectively compared with the same period of the previous year. As the process of urbanization in China is still in its infancy, passenger cars dominated by gasoline engines will continue to emerge. Specifically, the average monthly production of gasoline engine companies exceeds 10,000 units in January and the first quarter are still at the same level, still 30, the order of the top 15 companies by production size is: Chongqing Changan, SAIC-GM-Wuling , FAW-Volkswagen, Liuzhou Wuling Liuji, Shanghai GM Powertrain, Chery, Dongfeng Nissan Passenger Vehicle, Harbin Dongan Automobile Engine, Beijing Hyundai, Harbin Dongan Automobile Power, Shenlong, Shanghai Volkswagen, Guangzhou Auto Toyota Engine, Geely and Dongfeng Honda engine.
Among the companies with an average monthly output of more than 20,000 units, the cumulative year-on-year increase in production by more than 50% includes: Shenyang Aerospace Mitsubishi Engine (280.39%), Shenlong (121.72%), Shanghai General Motors Powertrain (120.84%), FAW Toyota (Tianjin) Engine (110.10%), Guangzhou Automobile Toyota Engine (87.99%), Dongfeng Nissan Passenger Vehicle (87.93%), Chongqing Chang'an (69.03%), Chongqing Pan'an Huaihai Power (59.25%), Geely (59.14%), Chery (58.53%) and Shanghai Volkswagen (56.36%). Although this cumulative output growth rate is still quite high, but the above companies are almost all negative growth in April, so the cumulative year-on-year growth rate has declined from the first quarter.
The common methods used in cutting metal are oxygas flame cutting, air carbon-arc cutting, and plasma-arc cutting. The method used depends on the type of metal to be cut and the availability of equipment. As a welder, oxygas or air carbon-arc equipment is the most common type of equipment available for your use.
The oxygas cutting torch has many uses in steelwork Often, the welder finds the cutting torch an excellent tool for cutting ferrous metals. This versatile tool is used for operations, such as beveling plate, cutting and beveling pipe, piercing holes in steel plate, and cutting wire rope.
When using the oxygas cutting process, you heat a spot on the metal to the kindling or ignition temperature (between 1400°F and 1600°F for steels). The term for this oxygas flame is the preheating flame. Next, you direct a jet of pure oxygen at the heated metal by pressing a lever on the cutting torch. The oxygen causes a chemical reaction known as oxidation to take place rapidly. When oxidation occurs rapidly, it is called combustion or burning. When it occurs slowly, it is known as rusting.
When you use the oxygas torch method to cut metal, the oxidation of the metal is extremely rapid and part of the metal actually burns. The heat, liberated by the burning of the iron or steel, melts the iron oxide formed by the chemical reaction and accelerates the preheating of the object you are cutting. The molten material runs off as slag, exposing more iron or steel to the oxygen jet.
In oxygas cutting, only that portion of the metal that is in the direct path of the oxygen jet is oxidized. The narrow slit, formed in the metal as the cutting progresses, is called the kerf. Most of the material removed from the kerf is in the form of oxides (products of the oxidation reaction). The remainder of the material is molten metal that is blown or washed out of the kerf by the force of the oxygen jet.
The walls of the kerf formed by oxygas cutting of ferrous metals should be fairly smooth and parallel to each other. After developing your skills in handling the torch, you can keep the cut within close tolerances; guide the cut along straight, curved, or irregular lines; and cut bevels or other shapes that require holding the torch at an angle. Partial oxidation of the metal is a vital part of the oxygas cutting process. Because of this, metals that do not oxidize readily are not suitable for oxygas cutting. Carbon steels are easily cut by the oxygas process, but special techniques (described later in this chapter) are required for the cutting of many other metals.
