Abstract (en)
[origin: WO9714877A1] A system and a method for controlling the amount of fuel injected into an internal combustion engine fitted with a catalytic converter. The signal (KCL) output by a first feedback loop (16, 18, 20, 12) and derived from the output (Vup) of a first probe (16) upstream from the catalytic converter (14) is corrected in a corrector circuit (22) by a value (KRICH) determined in a circuit (24) on the basis of the output (Vdown) of a second probe (26) downstream from the catalytic converter (14). The system and method are useful in internal combustion injection engines fitted with a catalytic converter.
