How To Test VNT Turbo?
Apr , 29 2019
Modern turbochargers always use a VNT type design, also known as a variable geometry, which can prevent your turbos over-speeding and causing serious damage. The turbo shaft speed is controlled by a nozzle ring and vanes which direct air to the turbo turbine wheel. As turbo shaft speed reaches optimum speed, the turbo vanes open and allow exhaust gases to pass around the turbine wheel and not thro...

The flow bench testing for vnt turbochargers
May , 18 2019
The flow bench is the final and essential stage for VNT turbocharger testing. Based on the turbocharger flow, we can calibrate the variable geometry section to enable the aftermarket turbocharger to achieve the same flow and performance as the original turbocharger. In addition, the flow bench can test the turbocharger's rotating speed and the performance of the compressor section and it also has ...

The difference between turbocharger and supercharger
Apr , 12 2022
A supercharger is an air compressor that increases the pressure or density of air supplied to an internal combustion engine. Turbocharger is a turbine-driven, forced induction device that increases an internal combustion engines power output by forcing extra compressed air into the combustion chamber. The key difference,A supercharger requires engine power to run,but the turbocharger runs off wast...

About Turbocharger Cooling System
May , 06 2022
About the cooling method of the turbocharger,every turbocharger is based on oil-cooled.Turbine blades are immersed in oil during operation, and the oil has a cooling effect while lubricating. Air cooling means that the cooling method of the intermediate is air convection cooling. Water cooling means that the intermediate has water channels, and when the engine is started, the water will flow throu...

The main reason of VNT Turbo failure - Carbon Deposits
May , 19 2022
At recent years,many diesel cars are fitted with a Turbocharger using a Variable Geometry or Variable Nozzle Ring. These VNT turbochargers are very effective in minimising the effects of turbo lag, resulting in a more responsive throttle especially at low engine speed and much improved torque. These systems work by changing the speed and direction of the exhaust gases onto the turbine wheel. At lo...

The dual mission of turbocharging technology
Jul , 14 2022
Turbocharger that in the eyes of many people think is to bring strong power to the vehicle components, from the birth to the general public, to today, it is not only a symbol of strong power, but also bear the responsibility of the car energy saving and environmental protection. Turbo: The end of large displacement? In the days before turbochargers were widely used in the automotive sector, large ...
