Performance of binary and ternary blends of gasoline, pyrogasoline and ethanol in spark ignition engines

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.
