Method for operating an internal combustion engine control system for an internal combustion engine and the internal combustion engine

The invention relates to a method of operating an internal combustion engine, in particular for load control and / or load control in the internal combustion engine, comprising: - an intake path 30 and a motor 10 having a number of cylinders Ai, Bi and one arranged upstream in front of the cylinders i, B receiver 80, wherein the intake path 30 comprises: - a charge with a compressor (51) and a bypass for bypassing the charging, and wherein - the receiver 80, an engine throttle and the bypass DK a compressor bypass throttle VBP is assigned; and is set depending on operating process in the method, a position of the engine throttle DK and / or the compressor bypass throttle (VDPK) for influencing a charge fluid. According to the invention it is provided that in particular, the intake path 30 is a Ansaugstreckenmodell associated, by means of which at least one mass flow and / or state of the charging fluid is determined before the engine 10, and more particularly based on a determination result, - the compressor bypass throttle VDBK is adjusted in dependence on the engine throttle DK.
