2. Wastegate - Wikipedia

   en.wikipedia.org/wiki/Wastegate

   The primary function of the wastegate is to regulate the maximum boost pressure in turbocharger systems, to protect the engine and the turbocharger. One advantage of installing a remote mount wastegate to a free-float (or non-wastegate) turbo includes an allowance for a smaller area over radius (A/R) turbine housing, resulting in less lag time ...

3. Boost controller - Wikipedia

   en.wikipedia.org/wiki/Boost_controller

   A 3-port solenoid-type boost controller A 4-port solenoid-type boost controller (used for a dual-port wastegate). The purpose of a boost controller is to reduce the boost pressure seen by the wastegate's reference port, in order to trick the wastegate into allowing higher boost pressures than it was designed for.

4. Variable-geometry turbocharger - Wikipedia

   en.wikipedia.org/wiki/Variable-geometry_turbocharger

   This design has a lower flow rate compared to VNT types so a wastegate may be incorporated with this design. [5] VGTs may be controlled by a membrane vacuum actuator, electric servo, 3-phase electric actuation, hydraulic actuator, or pneumatic actuator using air brake pressure. Unlike fixed-geometry turbines, VGTs do not require a wastegate. [6]

5. Turbocharger - Wikipedia

   Using a turbocharger spool valve to increase exhaust gas flow speed to the (twin-scroll) turbine; Using a butterfly valve to force exhaust gas through a smaller passage in the turbo inlet; Electric turbochargers [51] and hybrid turbochargers. A similar phenomenon that is often mistaken for turbo lag is the boost threshold. This is where the ...
