The significant growth forecasted in gasoline boosted engines and the more challenging regulatory requirements for emissions and fuel economy are leading to an aggressive engine downsizing trend. Two technology leaders have partnered in order to offer an optimized design in dual boosting systems which combine superchargers and turbochargers. The result is an air delivery boosting system that can accommodate high BMEP at all engine speeds without compromising transient response. Combining the skills of both companies, the advanced engineering groups joined efforts to perform an extensive simulation study over the course of a year aimed at defining a superior system design methodology. This study explored and analyzed the benefits of each boosting device. Two main configurations were considered based on the relative sequence of each device in the air path, namely: supercharger (SC) + turbocharger (TC) and TC + SC.
