Title: SUPERCHARGING SYSTEM FOR AN INTERNAL COMBUSTION PISTON ENGINE AND METHOD FOR OPERATING A WASTE GATE ARRANGEMENT
Abstract:
Described is a supercharging system and a method of operating a waste gate arrangement (7). The supercharging system comprises a turbocharger unit (2) having a compressor part (3) and a turbine part (4), an exhaust gas system (5) connecting the turbine part (4) with the engine (1), an inlet air system (6) connecting the compressor part (3) with the engine (1), a waste gate arrangement (7) having an upstream end (8) in flow connection with the inlet air system (6) downstream of the compressor part (3) of the turbocharger unit (2), and a valve (9) configured to regulate the flow of gas in the waste gate arrangement (7). A flow control unit (11) of the valve (9) of the waste gate arrangement (7) is mechanically connected to a thermally-responsive actuator (12).
