Comparison of passive and active methods for improving transient performance of turbocharged\ud engine systems

By Oliver S. Gilkes and Rakesh Mishra

Abstract

The drive to reduce engine emissions has placed an emphasis upon turbocharging especially with the\ud trend of engine downsizing (C. Macrae, (2006), A. Lefebvre et al. (2005)). Turbocharged vehicles\ud exhibit a weak point of poor drivability under transient running conditions. Previous work by Y. Matsura\ud et al (1992), has reviewed various methods of improving the transient engine performance. This paper\ud compares the passive method of reducing the inertia of the compressor wheel and the active method\ud of injecting air into the inlet manifold. The work has shown that both these methods improve the\ud transient response of the turbocharger. The effect of the active system is shown to be greater than\ud that of the passive method
