Porsche and BorgWarner variable turbine-sectional technology cooperation

When Porsche driver heard the "turbo" is the word, immediately think of the slave drive Porsche super strong power experience. The new Porsche 911Turbo will live up to the expectations and redefine the extraordinary experience of super-powered. This latest incarnation is the first to use dynamic variable turbine cross-section (VTG) gasoline engine models.

Resistant to high temperatures up to 1,000 ℃ (1,830 ° F)

So far, the cross section of variable turbine technology has been used in diesel engines. audi a6 1.8 turbocharger It is for technical challenges is the need to develop a gasoline engine can withstand the high exhaust gas temperature of up to 1,000 ℃ turbine materials, this temperature is much higher than the temperature of the exhaust gas of diesel engines. BorgWarner Turbo & Emissions Systems has successfully developed jointly with Porsche for the Porsche 911Turbo models using a variable geometry turbocharger gasoline engines. Heart turbo system is adjustable guide vane vortex section. These guide vanes in the low-speed, low-displacement condition is closed, thereby increasing the intake pressure of the engine. Compared with the conventional turbocharger, which greatly improves the response time and the acceleration at low speeds. Use of variable turbine cross section technology gasoline engine efficiency in all speed ranges were significantly higher than the standard discharge valves currently used type turbocharger. Accordingly, the fuel economy performance in each speed range is also a higher level.

Although it is applied with a variable geometry turbocharger diesel engine is very similar, audi k04 turbocharger but BorgWarner's engineers have developed a comprehensive re-release thermal module --VTG the most important element - to withstand the high temperature of the exhaust gas test . Troubled developed this particular challenge is to find the temperature of the material, this material needs to have an appropriate Friction and thermal expansion properties to ensure that the surface quality of machined components to meet the requirements and tolerances. In R & D, the new space materials to be applied, some of which have never been used in automobiles or turbocharger.
