    Abstract

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