| Charge pressure control vacuum transducer position | Mounted at rear on cylinder head of left cylinder bank | ||
| Charge pressure control vacuum transducer task | To generate modulated charge pressure for the pressure diaphragm units to obtain charge air pressure regulation independently of the PWM signal from the engine control unit. | ||
| Boost pressure control pressure transducer design | Plastic housing with coil for the battery voltage, resistance approx. 23 Ω, actuation by means of the PWM signal, frequency approx. 30 Hz | ||
| Charge pressure control vacuum transducer function | One of the valve plates actuated by the coil anchor increases the opening time to the atmosphere for an increasing duty cycle. This means that only part of the charge pressure acts from connection 1 on the pressure diaphragm units. |
