The invention relates to a charge air cooler () for fuel engine comprising:

Charge air cooler for fuel engine

A powertrain includes a variable ratio transmission device having an input shaft coupled to an engine and an output shaft coupled to a driven unit, a three-way power split transmission device including three input/output couplings, a first of which is coupled to a flywheel and a second of which is coupled to an electrical machine. The third input/output coupling of the three way power split transmission device is mechanically coupled to the engine and to the input shaft of the variable ratio transmission device.

Powertrain comprising an optimized energy recovery system

A power unit for an automotive vehicle includes an internal combustion engine, an electric machine electrically connected to electrical power storage arrangement, and a turbocharger comprising a first turbine located in an exhaust line of the engine. This power unit further includes a second turbine, located in an exhaust line of the engine and drivingly connected to the electric machine, and a transmission set. A first input/output of the transmission set is connected to the second turbine and a second input/output of the transmission set is connected to a crankshaft of the internal combustion engine. The transmission set has an adjustable speed reduction ratio between its first and second inputs/outputs.
