Effect of Biodiesel Blends on Diesel Engine

Abstract

The present research, utilised only renewable oil samples to reduce atmospheric pollution and also to decrease our reliance on fossil oil products and provide a direction towards alternative fuel usage in diesel engines. On a 1-cylinder, naturally water-cooled, 4S, CI diesel engine, the tests have been conducted as to create comparative results of performance-emission characteristics in between the blends of conventional diesel, biodiesel thumba, biodiesel polanga and ethanol fuel. With blends, the diesel engine has been tested as such: diesel fuel (D100) (v/v), thumba biodiesel 100% (T100) (v/v), polanga biodiesel 30% with addition of diesel 70% (P30) (v/v), and ethanol 10% with addition of diesel 90% (E10) (v/v). The engin performance parameters: BTE of E10 and P30 blend was incremented than the diesel fuel, while the blends T100 was close enough to diesel fuel as well; whereas, BSFC data of E10 blend was the lowest in between the others samples and for T100 and P30 also it decreased. The emission values for CO, NOx and UHC of the blend samples was less than diesel fuel. The maximum CO2 emission was released by D100 and least by P30 fuel blend, whereas, the unused O2 released was the reverse. The effects of direct inhalation of biofuel blends in IC engine were analysed properly and in near future this alternative oil can be applied in our society.

Effect of Diesel Engine Fuelled with Biofuel Blends

“…With different blends of polanga biodiesel being operated on a single cylinder, diesel engine and when compared with diesel fuel, the polanga biodiesel blends resulted into improved performance and reduced emission w.r.t diesel fuel [5].Addition of d dodecanol as r brake specific increase in thanolcontentr Mohammadi et al reported that blending ethanol with diesel fuel is effective in reducing nitrogen oxides (NOx) and particulate matter (PM),alsothe blending of fuel increased the HC and CO emissions [7]. Akash Paul et al found the BTE of ethanol 10% blend fuel was highest along with least BSFC for ethanol 10% blend, whereas, the CO, UHC, NO decreased for Thumba 100% and polanga biodiesel 30% when blended with diesel fuel [8]. researcher, utilised biodiesel along with a multi-DM-32di results show comparable performance and produce lowersmoke, CO…”

“…diesel fuel, and blending of ethanol with diesel fuel did not require any engine modification, the fuel samples were the fuel blend samples prepared diesel fuel 100% (D100), biodiesel neem 0% (N100), biodiesel polanga 50% blended with blended with diesel inhaled with neat diesel fuel and was operated by varying the load conditions as: 0%, 25%, 50%, 75% and 100%, to get ase data for diesel and to make an analysis in between the performance and emission data of Any new blend before beginning the experiment, the engine was operated for sufficient time till the last drop to wipe out the leftover fuel droplets from the previous tests.
