Automobile industry is a high degree of correlation with the industry, its deliberation on the development prospects and great potential for all to see. China's automobile industry has known 50 years of injustice storms Road, in 2000, with China's accession to the WTO, China's automobile demand in a "blowout" growth of the auto industry has also realized a sustained, rapid and steady development.

    Speed up the development of enterprises in the vehicle at the same time, promote the development of the parts and components industry, and spare parts for cars to enter the new era of corporate relations. Medecins Sans Frontieres automobile industry development model of globalization, mergers and acquisitions as well as restructuring of the parts and components industry increased integration. The key to a vehicle engine parts - spark plug industry has also accelerated development and formed its own characteristics. Spark Plug aggravated differentiation between enterprises, and gradually integrate into the global procurement systems, and modular Availability in the substantial increase in capacity. 

   Vehicle demand increased Spark Plug

   China's automobile production in 2006, sales reached 7279700 and 7216000, an increase of 27.32% and 25.13%. 2007 vehicle production is expected to reach 8.5 million. In fact, only 8.5 million more in 2006 than 1.2 million, and the growth rate is about 16%, than in 2006 is not the speed. Vehicle Population in 2006 is expected to amount 39 million on the basis of the 2010 reached 77 million.

   Motorcycle production in China in 2006 about 21 million Taiwan (domestic sales of 14.6 million units, exports 6.4 million units); 2007 production is expected to more than 21 million Taiwan, the domestic motorcycle 90.5 million for the tenure of Taiwan, motorcycles host the 2007 market will not be low Spark Plug in the demand for the year 2006.

   Total exports in 2006 Spark Plug Super 50 million, due to globalization auto parts procurement, the export of China's spark plug industry continued to grow into a major bright spot, export growth remained at around 50 percent.

   To sum up, the next few years, the annual demand for spark plugs will not lower than 3 ~ 400 million.

   Before the 1990s, domestic manufacturers Spark Plug only five. With the spark plug the release of huge potential market, after the mid-1990s, manufacturers jumped on the 100, production capacity has increased from several hundreds of millions of 10 million to upgrade only. In recent years, the rapid development of the domestic automobile industry also attracted a world-class production giant spark plug accession, Germany Bosch and Nanjing China and Germany set up a joint venture to set up factories in Shanghai NGK Japan, the United States champion door-to set up factories in Guangzhou, and wish to Qingdao set sparkplug parts production base, and so on. They have been completed in China's strategic layout, makes spark plugs, industry competition will be intensified.

    Spark Plug technical condition

    At present the most common is the sparkplug unipolar spark plug, spark plug this simple structure, process maturity, performance, stability, and have more than 100 years of history. With the rapid development of the automobile industry, as well as to the automobile emission increasingly stringent requirements, such as the implementation of China's National III standards, in 2008 Europe will be implemented more stringent EU IV standards, and the vehicle OBD system installed ( vehicle emissions since the GEMS) has become an inevitable trend, which made long-life spark plugs, fuel economy, environmental protection, and the development of more stringent requirements, this is a sparkplug enterprise development and direction. More than ordinary spark plugs, high-grade platinum (the Iridium) is the spark plug in this environment of the right moment.
     Platinum spark plug electrodes in the flashover is the use of laser welding parts on a small platinum tablets (Iridium gold). Platinum and iridium and the melting point of reaching the 1774 ¡æ and 2453 ¡æ, and because it only ¦µ1.1 mm diameter and ¦µ0.6 mm even ¦µ0.4 mm, in the space under the same pressure and flashover its breakdown voltage than needed ordinary spark plugs, will be reduced by 10% ~ 20%, platinum (Iridium) to facilitate the spark plug ignition, the acceleration performance, and more fuel economy, longer life (general sparkplug 1 ~ 20,000 km, platinum and iridium spark Sedar 8 ~ 100,000 km), and other advantages, the market has gradually become a luxury vehicles. Spark Plug domestic enterprises, Zhuzhou Xianghuoju Spark Plug Co. Ltd. in 1996 introduced the first platinum spark plugs, and in 2002 introduced a more durable the Iridium Spark Plug, favored by the market. The company platinum (the Iridium) famous domestic supply spark plugs have the engine manufacturers, such as Shanghai Automobile, Shenyang Mitsubishi, Anhui Chery, Mianyang Xinchen, an annual output of up to 2 million. Currently capable of producing platinum, iridium spark plugs, the only world-renowned foreign manufacturers in Japan NGK, Denso, Bosch of Germany, the United States, such as the champion and Outelai.

     Application of the domestic situation

     Faced with a growing number of high-power large displacement of the birth of luxury cars, the engine more compact structure, thermal load is also growing, on the one hand require spark plugs to the small form factor of development, such as Rhythm of Dongfeng Nissan the sparkplug on the vehicle used M12 ¡Á 26.5 small and long thread design, the world's most exquisite pocket most of the spark plug thread only 1 / 4 ", it was born in Zhuzhou Xianghuoju Spark Plug Company.

    On the other hand require excellent thermal conductivity of the spark plugs, if not timely dissemination of the heat out, ranging from the impact on engine power, and if the engine knock even as a fuel, thereby damage the engine. Based on the improvement of thermal conductivity properties, INCONEL 600 nickel electrode, double copper electrode spark plugs and long thread has become a trend.

    Spark Plug heat transfer about 63% through the center electrode ¡ú sealed gasket ¡ú shell and center electrode ¡ú thread sealing gaskets, and 20% through the centre electrode ¡ú way of sealing gaskets conduction out, we can see that the thermal conductivity electrode how important. INCONEL 600 nickel alloy is a nickel - Chrome - iron-based solid solution strengthening alloy, it is applied in the spark plug, a high temperature corrosion, and other excellent antioxidant properties, the thermal conductivity INCONEL 600 ordinary nickel alloy is 11 times about it than ordinary nickel alloy electrode spark plugs more erosion resistant to extend the life of a spark plug, is a novel, the spark plugs, environmental protection, energy conservation products.

     Another long thread spark plugs, the more and more applications, such as Elysee (16 V), Changan Ford's carnival, Shanghai Volkswagen's Passat 2.0 L, POLO cars, and Shenyang 4 G69 Mitsubishi engine, and so on are used in long thread spark plugs .
Development Trend

     Because of the surge in world oil prices, petrol was growing CNG (natural gas), and LPG (liquefied petroleum gas) to replace, especially in North China, natural gas is rich in resources, many of the original diesel engine manufacturers will be converted into a gas engine, will replace gasoline engine oil Dual-engine, now many domestic as Beijing, Chongqing, Chengdu and other big cities in the oil and gas taxi use two vehicles, buses, the use of natural gas. Natural gas combustion engine is characterized by slow, atmospheric pressure, high ignition voltage, thermal load, the fuel combustion mechanism and there is a change, which calls for the spark plugs, power lines, ignition coil structure has changed, in view of the characteristics of Gas Engine , Xianghuoju companies spark plugs, power lines, the overall design of the ignition coil, dual-use gas for spark plugs, oil and gas and power lines supporting the use of this power can reduce the conduction losses, the output waveform stability, improved engine performance started to purify the cylinder to reduce carbon deposition, extend engine life, the system stability.

    Spark Plug in the industrial area, the most famous non-United States companies STILL my mind. Spark plugs used in the main industrial units, petroleum pipelines, and other aspects of its work environment than in the more stringent gasoline engine, its fuel deal with the main garbage dump of emissions, pollution, corrosion strong pressure, the spark plug technology very strict, it is generally use platinum iridium, rhodium and other precious metal iridium spark plug, a bipolar electrode side, the four most common, high calorific value, different structures general, it is ordinary spark plugs Nanxing its service. As the processing industry sparkplug difficult, complex process control, the current domestic TORCH can do only one.

    Spark Plug domestic industry has nearly 50 years of history in the past 10 years, through the introduction of foreign advanced technology, the pace of development of spark plug soon, the country's Xianghuoju spark plug production in the world has the scale of the sixth, producing nearly 100 million only, and product quality is close to the world's leading NGK, Champion, Bosch and other brands level.

    In short, in the long-life spark plugs, small size, environmental protection, energy conservation, large-scale and the direction of development. Domestic spark plug manufacturing standards have been giants of the world - on. How foothold in the industry, the domestic production of spark plug plant in addition to maintaining labor costs, price, after-sales service, supplier relationship several aspects of the superiority, but also in the R & D capabilities, high quality, high value-added products, such as development formed the core aspects of their competition to become necessary, spark plug industry is the inevitable trend of development.
