Abstract

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.

Claims (37)

1. A supercharging system for an internal combustion engine, comprising:

a turbocharging device comprised of a turbine and a compressor;

said compressor and said turbine arranged on a compressor shaft;

a first planetary gear carried on said compressor shaft, said first planetary gear comprised of a first sun gear carried by said compressor shaft and a first ring gear;

a clutch unit;

a power transmission for connecting a crankshaft of the combustion engine to said first ring gear via the clutch unit, said power transmission comprised of a second planetary gear; said second planetary gear comprised of a second sun gear and a second ring gear; and

an electric motor/generator connected to said power transmission and said second planetary gear,

wherein the supercharging system delivers compressed air to the internal combustion engine during engine operation, and

wherein said second planetary gear, comprised of said second sun gear and said second ring gear, is aligned with said crankshaft.

2. The supercharging system of claim 1 , wherein said second planetary gear is configured to provide a power split between said compressor shaft, said electric motor/generator, and said crankshaft.

3. A supercharging system for an internal combustion engine, comprising:

a turbocharging device comprised of a turbine and a compressor;

a first planetary gear

a clutch unit;

a power transmission for connecting a crankshaft of the combustion engine to power said compressor via the clutch unit; and

an electric motor/generator, wherein the supercharging system delivers compressed air to the internal combustion engine during engine operation,

wherein,

said compressor and said turbine are arranged on a compressor shaft,

said first planetary gear is carried on said compressor shaft, said first planetary gear comprised of a first sun gear carried by said compressor shaft and a first ring gear,

said power transmission connecting the crankshaft of the combustion engine to said first ring gear via the clutch unit, said power transmission comprising a second planetary gear,

said second planetary gear comprised of a second sun gear and a second ring gear,

said electric motor/generator connected to said power transmission and said second planetary gear, and

said second planetary gear, comprised of said second sun gear and said second ring gear, is aligned with said crankshaft.

4. A supercharging system for an internal combustion engine, comprising:

a turbocharging device comprised of a turbine and a compressor;

a first planetary gear;

a clutch unit;

a power transmission for connecting a crankshaft of the combustion engine to power said compressor via the clutch unit; and

an electric motor/generator, wherein,

the supercharging system delivers compressed air to the internal combustion engine during engine operation,

said compressor and said turbine are arranged on a compressor shaft,

said first planetary gear is carried on said compressor shaft, said first planetary gear comprised of a first sun gear carried by said compressor shaft and a first ring gear,

said power transmission connecting the crankshaft of the combustion engine to said first ring gear via the clutch unit, said power transmission comprising a second planetary gear,

said second planetary gear comprised of a second sun gear and a second ring gear; and

said electric motor/generator connected to said power transmission and said second planetary gear, and

wherein said second planetary gear is configured to provide a power split between said compressor shaft, said electric motor/generator, and said crankshaft.

5. The supercharging system of claim 4 , wherein said second planetary gear, comprised of said second sun gear and said second ring gear, is aligned with said crankshaft.
