Abstract:
Simultaneous or independent control of a by-pass valve and a variable-geometry forced induction component on a combustion engine is based on operational parameters measured by various sensors provided as inputs to a control module. Sudden loss of power due to low turbine efficiencies is prevented during transitions between operating conditions of engine speed and load. Excessive peak cylinder pressures are also prevented by controlling engine boost pressure to a permitted limit at high engine speed and load.
