Abstract (en)

[origin: DE19736522A1] An IC engine has part of the exhaust gases recycled into an inlet manifold via a control valve and a flow restriction. The recycling rate is controlled (1) by a universal program modified by correction inputs related to engine and vehicle parameters, to produce a control program which matches the engine/vehicle combination. Correction signals are derived from various parameters including fuel injection rate, throttle pedal setting, coolant temperature etc.
