Apparatus for controlling engine parameters, in particular the power or r.p.m. in an internal combustion engine

摘要

The device has two or more adjustable elements via which the engine is influenced. Each of two or more specialised regulators (16,17) controls one adjustable element (6,10) according to a measured engine operating parameter actual value (Pist) and a predefined demand value (Psoll). A switchover device (18) is used to activate one of the controllers to control its associated adjustable element. One of the adjustable elements is the choke flap (6) in the engine air induction tract. One of the adjustable elements can be a controlled valve (10) arranged in a bypass line parallel to a compressor in the induction tract, pref. an exhaust gas turbocharger.
