ABSTRACT:
A system for controlling the supercharge pressure in an internal combustion engine having a mechanical supercharger which is connected to the crankshaft of an engine and includes a variable compressing construction capable of varying the internal compression ratio. The system comprises a supercharge pressure varying assembly for varying the supercharge pressure, a detector for detecting the operational condition of the supercharge pressure varying assembly, and a control device for operating the supercharge pressure varying assembly into a supercharge pressure reducing position in response to the detection, by the detector, of the fact that the supercharge pressure varying assembly is in a low level compressing state in an operational condition of the engine in which the mechanical supercharger should be brought into a high level compressing state. Thus, even if an abnormality occurs in the variable compressing assembly, an increase in the temperature of the intake gas in the engine is prevented.
