Nozzle Ring In Turbocharger

Recent years, he automobile industry has been booming in China and it also has been new pillar to national economy. China has become largest auto market in the world in the year of 2010. With the greatly improved of car ownership, the difficult problem of environmental pollution brought by cars has become placed in front of people.

The invention and application of turbocharger technology are not only decrease fuel consumption and improve the power of the engine, but also reduce the harmful gas in automobile exhaust components. So Countries of the world, especially the developed countries put a lot of manpower in turbocharger technology and manufacturing. Variable nozzle turbocharger technology is a new technology and has been widely used. It has broad future development.

Nozzle ring vane is the key component for variable nozzle turbocharger. At precent, there is nothing special processing equipment since this technique has just appeared. Now the main process of nozzle blade machining is casting or forging blank. Then machining and optical finishing. Generally speaking, people adopt the method of grinding wheel by hand in China. This is not efficient. However there are many technical personnels studying on the new method in order to improving efficiency.
