Evaluation of an experimental induced ignition engine under different gasoline. Ingenius [online]. 2021, n.26, pp.17-29. ISSN 1390-860X.  https://doi.org/10.17163/ings.n26.2021.02.

The internal combustion engine with provoked ignition is a thermal machine that enables obtaining mechanical power from the chemical energy of a fuel. The objective of this work was to evaluate the performance of an internal combustion engine through the balance of energy and exergy, under the individual use of the three types of gasoline sold in Ecuador (Super, Extra and Ecopais). The experimental methodology consisted of starting the engine with the individual use of gasoline until reaching its maximum power at engine speed, and taking measurements of temperature, specific fuel consumption and air-fuel ratio during 3 minutes. Results show an energy efficiency of 11.31% for the Super gasoline, 10.75% for the Extra gasoline and 10.39% for the Ecopais gasoline. Regarding exergy efficiency, 58.81% was established for the Super gasoline, 58.89% for the Extra gasoline and 59.19% for the Ecopais gasoline. Results enable us to conclude that there is an exergy potential for improvement that may be an opportunity to increase energy efficiency.
