The internal combustion engine (10) comprises a bleed air channel (18) which is located to divert compressed air at a location in or down¬ stream from the first compressor (12) and upstream of the internal combustion engine (10). A second turbine (15) is arranged for receiving bleed air from the bleed air channel (18) to recover energy from the bleed air channel (18). It also relates to a vehicle comprising such an internal combustion engine system (2).
