The invention refers to a supercharging system (6) for an internal combustion engine (1) incorporating in combination, a turbine (7), a compressor (8) and an electrical driven system (20) that is connected by any power transmission system (16, 19) to the crankshaft (4) or any other vehicle drive sha
The invention refers to a supercharging system (6) for an internal combustion engine (1) incorporating in combination, a turbine (7), a compressor (8) and an electrical driven system (20) that is connected by any power transmission system (16, 19) to the crankshaft (4) or any other vehicle drive shaft of an internal combustion engine, where the turbine inlet is subjected to exhaust gases, causing the turbine wheel to rotate and thereby via the drive shaft causing mechanical rotating power.
