Experimental investigation on combustion performance emission characteristics of biodiesel blend from waste feedstocks on modified stationary engine

Abstract

Global energy consumption continues to rise steadily with newlineindustrialization and population growth. To meet the current energy demand, newlinefossil fuel-based petroleum diesel fuel has been the primary source. However, newlinegrowing concerns regarding fossil fuel depletion, environmental pollution, newlineglobal warming, and the escalating prices of petroleum diesel have prompted newlineextensive research into alternative renewable energy sources. The increasing newlinedemand for sustainable and renewable energy sources has led to a focus on newlinebiodiesel as an attractive alternative to fossil fuels, particularly in the newlinetransportation sector. Biodiesel has emerged as a promising substitute fuel for newlinediesel engines due to its fuel properties, which closely resemble those of newlineconventional diesel. In the present study, Waste Cooking Oil Biodiesel newline(WCOB) and Chicken Fat oil Biodiesel (CFB) which are produced from newlinewaste feedstocks have been proposed as alternatives to petroleum-based fossil newlinefuels. Through an extensive review of the literature, it was noted that the fatty newlineacid composition of biodiesel significantly affects its physical and chemical newlineproperties. It was also observed that blending biodiesels with different newlinesaturation levels can lead to improvements in fuel properties. Based on these newlinefindings, WCOB and CFB were mixed in various proportions and produced newlinethe fuel samples of BDB W80C20, BDB W60C40, BDB W50C50, BDB newlineW40C60, BDB W20C80. The prepared biodiesel samples were investigated newlinein stationary engine to assess their feasibility as alternative fuels. newline
