B - intake and turbocharging circuit

B - INTAKE AND TURBOCHARGING CIRCUIT

This consists of the following main components

1. Hot wire air meter (debimeter);
2. Throttle case;
3. Engine idle speed actuator;
4. Three-way turbocharging control solenoid;
5. Turbo by-pass valve;
6. Intercooler (intercooler);
7. Turbo regulation actuator (Waste-gate);
8. Turbocharger;
9. Air cleaner;
10. Intake air temperature sensor;
11. Absolute pressure sensor or barometric capsule.

Two sensors are also present; inlet air temperature sensor (10), absolute pressure sensor or baro-metric capsule (11). Despite being included in the electric/electronic circuit, these are responsible for controlling turbocharging.
