Abstract

Fuel consumption and the emission of pollutant gases, carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx), derived from fuel combustion formulated from pure petrol and mixed at 5, 10, 15, 20 and 25% v/v of dehydrated ethanol are evaluated. A monocylindric, four stroke, 196 cc, small non-road engine (SNRE), locked to a generator with maximum power of 2,400 W, at 0, 600, 1.200, 1.800 and 2.000 W, was employed. An automatic analyzer similar to that normally employed in the inspection of engines was used to determine gas emission. Results showed that decreases in CO, HC and NOx concentrations reached 75, 67 and 7% for the lowest charge (0 W) and 189, 3 and 43% for the highest one (2000 W), respectively, due to the gradual addition of ethanol to petrol. However, a mean 10% increase in fuel consumption was reported.
