Downsizing charged SI engine

10/21/2013

The requirements for charged SI engines lead to conflicting goals when laying out exhaust turbochargers. On the one hand, a larger exhaust turbocharger is meant to achieve a high output, while on the other hand the maximum torque should be reached even at low engine speeds without creating the impression of a turbo lag.

However, increasing the mean effective pressure is limited by the occurrence of unwanted pre-ignition phenomena.

    • FGT
    • Knocking
    <
    >
    With conventional wastegated turbochargers or fixed geometry turbochargers (FGT), a turbine flow area cannot be adjusted during operation.
    Knocking is abnormal combustion in which the air-fuel mixture ignites prematurely due to exposure to high temperature and pressure, creating an unwanted high-frequency noise. When the compression ratio is increased, the temperature at compression top dead center (TDC) also rises, increasing the probability of knocking.
