Effect of Injection Timing in Reducing the Harmful Pollutants Emitted from Ci Engine Using N-Butanol Antioxidant Blended Eco-Friendly Mahua Biodiesel

Abstract

Consuming non-renewable energy sources has genuine and long-standing unfavorable consequences on people's health, neighborhood networks and ecosystems, and also on the worldwide atmosphere. The burgeoning demand and use of diesel engines in various elds cause emission of exhaust gases like NOx and CO that lead to serious environmental pollution and hazards like global warming, respiratory problems, and so on, has necessitated a reduction in the use of diesel and addition of suitable biodiesel. Mahua biodiesel blend has also been considered as a safe renewable fuel for conventional engines. This is due to its desirable properties such as rapid growth rate, higher productivity, and the ability to utilize CO 2 into fuel. The introduction of an antioxidant, preferably n-butanol eliminates these harmful emissions from the diesel engine. In this experimental investigation, mahua biodiesel blend mixed with nbutanol has been used as test fuel in a conventional engine. Because of the special character n-butanol has been chosen for use with the mahua biodiesel blend. About 20-30 vol.% of n-butanol has been blended with 80 vol.% of diesel and tested. The manufacturer set injection timing was 23 o CA bTDC. The injection timing is preferably between 21 o CA bTDC and 25 o CA bTDC. Nitrogen oxides and carbon monoxide are reduced by 49 percent and 5.88 percent, respectively, when a blend of B20 + D80 + 30% nbutanol is used at 21 o CA bTDC relative to diesel fuel. The smoke and hydrocarbon emission of blend B20 + D80 + 30% n-butanol at 25 o CA bTDC is reduced by 40% and 38.07%, respectively, related to diesel. The brake thermal e ciency for entire injection timing has been identi ed to be increased correlated to all other test blends. The brake thermal e ciency in blend B20 + D80 + 30% n-butanol of 25 o CA bTDC is increased by 15.30%, when compared with diesel fuel. These promising results assure that mahua biodiesel blend containing antioxidant would be eco-friendly fuel.

A Comprehensive Review of the Properties, Performance, Combustion, and Emissions of the Diesel Engine Fueled with Different Generations of Biodiesel

“…Thus, better atomization and evaporation lead to more smoke being oxidized. Elumalai et al [257] investigated the effects of injection timing and N-butanol antioxidants on smoke emissions. Figure 33a-c indicates the smoke emissions of pure Mahua biodiesel and the biodiesel added N-butanol antioxidant.…”

“…Its green credentials include renewability, biodegradability, non-toxicity, reduced CO and CO 2 emissions, sulfur-free composition, and straightforward production [4]. Moreover, biodiesel is environmentally friendly because it minimizes hazardous exhaust emissions [5,6].…”

Experimental Investigation for Determining an Ideal Algal Biodiesel–Diesel Blend to Improve the Performance and Mitigate Emissions Using a Response Surface Methodology

“…The primary cause of smoke opacity production is typically poor combustion based on an excessively rich or lean mixture. This may be addressed by increasing the amount of O 2 molecules in the chamber, which leads to improved combustion. ,− Variability in smoke opacity for the tested fuels is shown in Figure . The study concluded that smoke emissions increased as engine load increased from idle to maximum condition.…”
