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

Abstract

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.

Performance, Emission, and Catalytic Activity Analysis of AL2O3 and CEO2 Nano-Additives on Diesel Engines Using Mahua Biofuel for a Sustainable Environment

“…The figure clearly shows that the mahua biofuel blends tested used more fuel than the nano-additive blends. Physical properties of aluminum oxide and cerium oxide, such as increased surface area per volume ratio, compact size, and homogeneous distributions, lead to improved catalytic performance; increased combustion via oxidation; improved fuel air mixing and atomization; and avoided blockage, all of which contribute to the fuel consumption reduction attributed to nanoadditives. − Increases in the volume fraction of aluminum oxide and cerium oxide in test fuel blends initially result in decreases in the BSFC; for instance, the MAH B20 AL50 CE50 blend consumes 10.21 kg/kWh, while MAH B20 AL100 CE100 consumes 10.01 kg/kWh. Subsequently, increases in the proportion of nanoadditives result in a significant increase in fuel consumption; the MAH B20 AL150 CE150 blend consumes 10.53 kg/kWh.…”

Effect of Alumina and Bio‐Based Calcium Oxide Nanoadditives on Reduction of Emissions and Performance Improvement in a Common Rail Direct Injection Diesel Engine Fueled with B20 Blend of Waste Cooking Oil Biodiesel

“…It falls between 0.25 and 0.3 kg kWh À1 range. [30][31][32] Higher surface volume ratios, compact size, and uniform distributions of aluminum oxide and calcium oxide result in improved catalytic performance; combustion is increased because of improved oxidation and improved atomization and fuel-air mixing thus preventing blockages, all these contribute to reduction in BSFC values. Some of the studies published similar results with the same tendencies.…”
