Tubocharged-internal combustion engine e.g. drive motor, for use in e.g. passenger car, has additional device with external compressor driven by engine, and pressure reservoir is connected with external compressor over pressure pipe

摘要

The engine (1) has a turbocharger (6) for permanent increasing of the load pressure, and an additional device (10) with an external compressor (11) that is driven by the engine. A pressure reservoir (14) is connected with the external compressor over a pressure pipe (12), and an inflow unit (17) is connected with another pressure reservoir (14`) over an auxiliary air pipe (16) that is provided with a control valve (15). The inflow unit is arranged at an exhaust gas tract of the engine in flow direction axially in-front of a turbine (7) of the turbocharger. An independent claim is also included for a method for load pressure regulation of an internal combustion engine.
