Abstract
Bioethanol is a promising alternative to gasoline. It has a high Octane number and its combustion in spark ignition engines gives lower pollutants compared to gasoline. In this study, bioethanol was added to gasoline at 10% and 20% volume fractions to assess the effect of this addition on the performance and contaminants of the single cylinder drive. The experiments were carried out using conventional Iraqi gasoline (has an octane number= 82). The results showed that the addition of 10% ethanol to gasoline increases the useful compression ratio from 8: 1 in the case of gasoline separately, to 9.5: 1 with this addition, leading to better performance of the engine, Adding 10% bioethanol led to decrement in CO and CO2 concentrations significantly.
