Boost pressure control valve task | To regulate boost pressure | ||
Boost pressure control valve function | The boost pressure control valve is closed by the boost pressure control vacuum transducer (Y31/5) via the vacuum unit (110/10), thereby allowing exhaust gases to bypass the turbine wheel (g). The bypass flap (a) is actuated by means of the Control linkage(b). When the bypass flap is open, no precompression takes place and the engine operates as a naturally aspirated engine |
