Performance and Environmental Effects of CeO2/ZrO2 Nanocomposite in Triple Blend Methyl Ester of Pumpkin and Neem Seed Oil Dosed with Diesel on IC Engine

The goal of this work is to evaluate the impact of CeO2/ZrO2 (CZ) nanocomposite materials on performance and emission characteristics of direct injection (DI) diesel engine fueled with ternary blends of pumpkin oil methyl ester (PME) and neem oil methyl ester (NME). The blend B20 (10% PME +10% NME +80% diesel) and various CZ nanocomposite blended fuels such as B20CZ25 (B20 +25 ppm CZ), B20CZ50 (B20 +50 ppm CZ), B20CZ75 (B20 +75 ppm CZ), and B20CZ100 (B20 +100 ppm CZ) were prepared and used for analysis. Pumpkin and neem seed oil were chose for this study due to noble economic feasibility, and they were transesterified with methanol and sodium hydroxide (NaOH) in order to get corresponding methyl esters. The experimental findings demonstrates that adding CZ nanocomposite improves brake thermal efficiency (BTE) and reduces brake specific fuel consumption (BSFC) at full load, as well as being beneficial in reducing harmful gases such as carbon monoxide (CO), hydrocarbon (HC), and nitrogen oxides (NOx). The study suggested that CZ nanocomposite with ternary blend will be a viable new strategy for improving engine performance and lowering emission characteristics without modifying the engine.
