Abstract (en)
[origin: FR2892769A1] The method involves determining richness of carbide mixture entering into combustion cylinders by determining if an engine operating point assesses the richness, filtering an output signal of a richness probe, comparing the filtered signal to a preset threshold and delaying the stabilization. Injection duration is increased by intervals, according to the richness if the filtered signal value is lesser than the threshold, where the injection duration increasing coefficient represents alcohol rate present in a main tank of an engine.
