Abstract
Low Carbon Vehicles and challenging missions standards are pushing the engine boosting system beyond the limits of current technology with the aim to aggressively downsize the internal combustion engine. This approach is one of the most promising engineering solutions to achieve a rapid, large scale decarbonisation of road transport. However, a detailed analysis of boosting options and matching techniques for the future gasoline and diesel engines is essential if we expect to meet the needs of heavily downsized engines and future hybrid power trains (including range extenders). The actual state of the art for down sizing has moved towards the introduction of more complex systems; such as double stage turbo compressor system, a combination of turbocharger and volumetric compressor or electric assisted supercharger/turbocharger combination. These go well beyond the traditional optimization of single stage turbocharger. Energy utilisation can be improved in all these cases if the turbocharger design/selection is taken in the context of its true operating environment (carefully considering the unsteady flow energy contained in the exhaust engine stream).
