Abstract

The emission of Unburnt Hydrocarbon (UHC), Oxides of Nitrogen (NOx), Carbon Monoxide (CO), and Carbon Dioxide (CO2) from internal combustion engine have been seen to cause negative environmental impact and a major source of greenhouse effect. This paper provides a better understanding and strategies for use of biofuel ethanol as a blend with gasoline to reduce emissions in 2-stroke engine small power generaor. An experimental study on a single cylinder domestic portable power generating set of fixed speed has been used with gasoline ethanol blends in ratio of 100% gasoline (E0), 50% gasoline ethanol blends (E50) and 100% ethanol (E100) under varying engine loads. The results showed that the CO and HC emission decreases as a result of the leaning effect caused by the ethanol addition. The CO2 emission was also observed to increase because of the improved combustion as a result of leaning effect of ethanol addition, in particular the E100. The NOx emission for E100 shows the most interesting result of decreasing from idle load to zero at the maximum load.
