Abstract

<div class="section abstract"><div class="htmlview paragraph">The present study aims to determine the comparative performance evaluation in terms of fuel economy (kmpl) and wide open throttle (WOT) power derived from set of different blends of high octane gasoline fuel(s) i.e., Neat Gasoline (E0), E10 & E20 (With different dosages of additives) in high compression ratio (HCR) motorcycle on chassis dynamometer facility.</div><div class="htmlview paragraph">With the Government of India focus on use of alcohol as co-blend of gasoline with the endeavour to save foreign exchange and also to reduce greenhouse gases (GHG) emissions. The commercially available blended fuels, E10 & E20, have high research octane number (RON, 92-100) and as per the available literature high RON fuel have the better anti-knocking tendencies thereby lead to higher fuel economy.</div><div class="htmlview paragraph">There are various routes to formulate high octane fuel (refining technologies, additive approach & ethanol blending route) in the range of 92-100 octane number which are currently commercialized in Indian market. In the present study, ethanol based high octane fuel blend(s) along with doping of novel indigenous type of additives (multifunctional additive & octane booster) to achieve the utilization benefits in terms of fuel economy (FE) & power improvement.</div><div class="htmlview paragraph">The findings of present study largely suggest that with the high octane fuel blends (only ethanol) the fuel economy and Wide Open Throttle (WOT) power reduces. On the other hand, by adding gasoline multi-functional additive (GMFA) in combination of octane booster in the ethanol blended fuels, fuel economy and WOT power are compensated fairly. Fuel economy and Wide Open Throttle (WOT) power were investigated under operating conditions (Indian driving cycle - IDC). On adding ethanol only by 10% and 20% in gasoline the fuel economy is lowered by 1.9% and 4.94% respectively. The loss in fuel economy is reduced by 0.74% and 3.36% through addition of indigenously developed GMFA with Octane Booster in E10 & E20 gasoline blends.</div></div>
