An Experimental Investigation on DI-CI Engine Characteristics Fueled with Green Synthesized Nanoparticle Doped with Biodiesel Blends

Abstract

The green fuel technology with eco-amicable processes and novel chemical action is becoming more popular. It is very essential to overcome worldwide problems associated with the environment. In this work, preparation of green synthesized silver nanoparticles (AgNPs) are discussed and experimentally investigated the DI-CI engine characteristics of diesel, B20 (ethyl esters of green biodiesel from neem oilseed) and B20GS20 (B20 doped with the green synthesis of silver nanoparticles from neem leaf extract) as a test fuel. Converting the raw neem oil into the biodiesel by transesterification process using ethanol as a solvent and KOH as a catalyst. Properties of various nanoadditive biodiesel blends and its performance, combustion and emission attributes of DI-CI engine are compared and represented. Neem leaf extracts act as a naturally occurring reagent for producing nanoparticles. With the assist of an ultrasonicator, the bio diesel-diesel blends (B20) doped with green synthesized 20 ppm nanoparticles are prepared. The properties of test fuel are tested and compared with ASTM standards are presented in this paper. The experimental investigations concluded that green synthesized silver nanoparticles act as diesel-green biodiesel blend (B20) additives in diesel engines as the test fuel. At the maximized load condition, in comparison with B20, test fuel enhances the BTE by 1%, significantly reduces the adverse emissions such as HC, CO, and smoke level by 2.46, 3.07, and 2.97%, respectively, and increases NOx by 1.66%. B20GS20 combustion characteristics like peak pressure rise and heat release rate are slightly enhanced by 1 and 1.9% compared to B20.
