Performance, Emissions, Combustion Characteristics and Particulate Size Measurement of Alcohol-Gasoline Blends in Medium Duty SI Engine

The rise in consumption of petroleum products with time and imposition of stringent emission norms worldwide has created the need of alternative fuels which can displace these conventional fuels. The alternative fuels are economical, environmental friendly and easily available energy sources as  compared to the conventional fuels. There are many alternatives in the list like  Ethers, biodiesel, alcohols etc. Among these, alcohols mainly  ethanol  and methanol seems to be great alternative because of their chemicals as well as  physical characteristics.  Alcohols  are simply produced from biomass feed stocks. Alcohols have higher octane number (methanol (99) and ethanol (100)) compared to gasoline thus allowing engines to have higher compression ratio and hence the thermal efficiency. Alcohols have higher latent heat of vaporisation (methanol(1098kJ/kg) and ethanol(838kJ/kg)), thus the increased cooling effect leading to less amount of NOx formation and also increased volumetric efficiency with less work required during compression stroke. Since, the oxygen content in alcohol are higher, so the emissions from the alcohol gasoline blends are less. Thus, currently in this latest BS-VI compliant Maruti Wagon R engine (K10 B Model), different regulated and unregulated emissions are measured using methanol gasoline blends of different proportions.
