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.
