Nowadays, the engine charging practice is widely adopted in the automotive field in relation to the “downsizing” technology: the reduction of the displacement and the adoption of a higher boost pressure, through a charging system, allow shifting the engine operating point in a zone of higher efficiency for a given engine torque. On the other hand, given a certain displacement, a supercharger can be adopted to increase the performance of the engine. The objective of this work is to provide a detailed analysis about the feasibility of the implementation of a charged engine to a motorbike, with main focus on the possibility to achieve a challenging performance target: in a first stage, several engine architectures (In-line, V-configuration, Boxer) together with different charging concepts (centrifugal or volumetric compressor, with mechanical or fluid-dynamic connection to the engine) have been analyzed from the point of view of packaging.
