Abstract: The present work aimed to study the performance of binary and ternary blends of gasoline, pyrogasoline and ethanol in a spark ignition (SI) engine. Pyrogasoline was obtained by simple distillation of a pyrolysis bio-oil produced from used cooking oil and had a LHV of 39.4 MJ.kg^-1. Performance tests were done in a SI engine comparing gasoline blended with 10 wt. % pyrogasoline, 10 wt. % ethanol and a mixture of 5 wt. % pyrogasoline + 5 wt. % ethanol with conventional gasoline as a standard fuel. The effect of fuel composition in engine performance parameters (torque, energy consumption and efficiency) was evaluated. Results indicate that pyrogasoline may be used as a gasoline additive, as an alternative or complement of ethanol, contributing to increase the fraction of renewable advanced fuels used.
