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 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...
