Abstract
Bioethanol is one of the renewable and alternative fuels for conventional gasoline. Bioethanol is manufactured from sugar containing crops like sugarcane, rice straw, etc. by fermentation process. In India, 10% ethanol is already blended with gasoline and 20% will be added by 2024. In this experimental work, different premium gasoline bioethanol blends are prepared and different properties like physical, chemical & Thermodynamic properties of fuel blends are determined. It was found that the lower heating value of premium gasoline bioethanol blends decreases with increasing percentage of bioethanol. Also, density, kinematic viscosity increases with increase in percentage of bioethanol in fuel blend. The research octane number (RON) and motor octane number (MON) is also improved by increasing percentage of bioethanol in premium gasoline ethanol blends. There was enhancement in the Stoichiometric air fuel ratio by increasing quantity of bioethanol in blends. Flash point decreases considerably with increase of percentage of blends. Also, in two wheelers, CO emissions are 33% lower than neat premium gasoline in case of E20 blended fuel. Carbon monoxide, Carbon dioxide, hydrocarbon emissions decreases variation of spark advancement and retardment.
