| TURBOCHARGER SYSTEM ILLUSTRATION |
- The turbocharger system is comprised of the Variable Nozzle (VN) type turbocharger and ECM.
- The turbocharger has a nozzle vane which opens and closes to control the volume of the exhaust gas flowing into the turbine. This, in turn, controls the boost pressure. When the nozzle vane moves towards the closing direction, the pressure increases. When the vane moves towards the opening direction, the pressure decreases.
- The turbocharger actuator built onto the compressor housing side actuates the nozzle vane. The nozzle vane position sensor built onto the actuator detects the opening angle of the nozzle vane. The ECM receives a nozzle vane position sensor signal. Based on this signal, the ECM operates the DC motor and controls the nozzle vane opening angle.
- The ECM controls the nozzle vane position according to the driving conditions in order to create the optimal pressure.
