How does REFONE to set the VNT turbocharger?

2019-02-26


Modern turbochargers use a VNT type design, also known as a variable geometry. 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 through the turbo Blades.


Refone has introduced the uniquely designed VNT flow bench to do the work of VNT turbochargers' calibration and testing. Our VNT calibration bench will test and calibrate not only the Minimum Flow, but will also test and calibrate turbo Maximum Flow. This will make sure that not only is your new turbo or chra operating at the correct engine RPM, it is also never over boosting.
