Recently, Torch's "composite alumina insulator spark plug and its manufacturing method" project won the first prize of Hunan Province Patent.
In recent years, in order to meet the requirements of energy saving, environmental protection and safety, the global automotive industry engine design tends to be compact and lightweight. The comprehensive application of turbocharging and in-cylinder direct injection technologies has made the working conditions of spark plugs more demanding. , Put forward higher requirements on the performance of the spark plug and its insulator. Therefore, the use of alumina with small original crystal size, high reactivity and low Na2O content to prepare high-performance spark plug insulators has gradually become an inevitable choice for spark plug manufacturers at home and abroad.
Torch’s “composite alumina insulator spark plug and its manufacturing method” project is the first domestic and international use of insulators with two different material structures, which has reduced the production cost of ceramic insulators by more than 50%; it has achieved insulator distribution on mass production lines Layer production method, the production technology level has reached the international advanced level; the application of this patented technology will also improve the mechanical strength, electrical resistance and impact resistance of the ceramic, which will help improve the performance of the engine and reduce the environmental pollution caused by insufficient engine combustion . At present, the patented technology products have entered major domestic OEMs, with a market share of 50% of OEMs, and the series of products are sold to more than 50 countries and regions including the United States.
