The article is devoted to investigation of fuel supply control efficiency in a spark ignition engine equipped with a catalytic converter during use of ethanol-containing fuels with different ethanol content. The study involves determining the efficiency of fuel supply controlling algorithm for the engine, which is powered by conventional petrol and non-adapted for using fuels with high ethanol content. Within the study the following fuels were used: petrol, ethanol and fuel blends with ethanol content varying from 15 to 90%. The efficiency of fuel supply control is evaluated in terms of providing the specified fuel-air mixture composition, fuel consumption and emissions in transient engine operation modes during vehicle motion in the driving cycle. The data obtained during the engine bench tests using petrol and ethanol-containing fuels were used for evaluation.
