“…Excess oxygen provides a more favorable environment for combustion, facilitating the quick initiation and propagation of the flame front and thereby reducing the ID. Taken together, the superior fuel properties of MEMSO biodiesel, including improved ignition quality at higher temperatures, the presence of additives, and the excess oxygen content in the fuel, contribute to the lowest ID – observed at all loads in Figure .…”

The rapid depletion of crude oil and environmental degradation necessitate the search for alternative fuel sources for internal combustion engines. Biodiesel is a promising alternative fuel for compression ignition (CI) engines due to its heat content and combustion properties. Biodiesel blends are used in various vehicles and equipment, such as cars, trucks, buses, off-road vehicles, and oil furnaces. Biodiesel can reduce emissions from CI engines by up to 75% and improve engine durability due to its high lubricity. However, biodiesel has some drawbacks, including a performance reduction and increased nitrogen oxide emissions. Therefore, this study aims to investigate using environmentally available biodiesel in a low-heat rejection engine and an antioxidant additive to enhance the performance and reduce nitrogen oxide emissions. India currently has several biodiesel sources, including mango seed oil, mahua oil, and pongamia oil, which can be effectively utilized in CI engines by adding l-ascorbic acid. The experimental work involves a single-cylinder 4-stroke water-cooled direct injection CI engine with a power output of 5.2 kW. The engine’s cylinder head, piston head, and valves are coated with lanthanum oxide using the plasma spray coating technique, with a thickness of 0.5 mm. The coated and uncoated engines are tested with different proportions of mahua oil, mango seed oil, and pongamia oil. The results show that the engine’s performance is significantly improved compared to the baseline engine at all loads. Additionally, these biodiesels exhibit a notable reduction in nitrogen oxide emissions when combined with l-ascorbic acid.

“…This could be rectified by the presence of the O 2 molecules in the combustion, which leads to improved combustion. Due to the high viscosity and low volatility of biodiesel, it affects the atomization properties of the fuel and leads to poor combustion. − Further, the smoke opacities for the emulsified blends of B20CuO25, B20CuO50, B20CuO75, and B20CuO100 were found to be 11.6, 10.9, 10.1, and 10.3 N, respectively. B20CuO75 was revealed to have 17.58% lower smoke emissions than B20 without nanoadditive and 9.82% lower emissions than diesel.…”

The present work covers the preparation of biodiesel from jatropha oil through the transesterification process followed by its characterization, and furthermore, performance and emission analyses were done in terms of blending biodiesel with fossil diesel and CuO nanoparticles. Jatropha biodiesel blends (B10, B20, and B30) were chosen for this preliminary investigation based on the observation that B20 outperformed other blends. Next stage B20 with copper oxide (CuO) nanoparticle concentrations of 25, 50, 75, and 50 ppm are used to examine the performance and emission characteristics of a constant speed single cylinder, 4stroke, 3.5 kW compression ignition (CI) engine. Finally, The response surface methodology (RSM) was utilized to determine the optimal nanoparticle concentration for B20. The results revealed that the blend of B20 with 80 ppm nanoparticles had the highest desirability (0.9732), and the developed RSM model was able to predict engine responses with a mean absolute percentage error (MAPE) of 3.113%. A confirmation test with an error in prediction of less than 5% verified the model's adequacy. When comparing optimized B20CuO80 to diesel, brake specific energy consumption (BSEC) increased by 8.49% and brake thermal efficiency (BTE) was lowered by 3.34%. Hydrocarbon (HC), carbon monoxide (CO), carbon dioxide (CO 2 ), nitrogen oxide (NOx), and smoke emissions were reduced by 3.66% and 2.88%, 4.78%, 22.9%, and 20.54%, respectively, at 80% load. As a result, the B20 blend with nanoparticle concentrations of 80 ppm may be used in current diesel engines without engine modification.

Lemon peel (LP) was integrated into polyvinyl alcohol/chitosan (PVA/CS) to produce innovative active food packaging films via solvent‐casting method. PVA/CS/LP biocomposites were prepared with varying LP contents (1%, 3%, and 5% by weight) to investigate their impact on morphological, thermal, structural, biodegradability, solubility, mechanical, and bioactivity properties of the PVA/CS blend. Scanning electron microscope analysis revealed a uniform dispersion of LP within the matrix. Attenuated total reflectance ‐ fourier transform Infrared spectroscopy (ATR‐FTIR) study confirmed interaction between lemon peel and the matrix. The incorporation of LP enhanced thermal stability and enzymatic activity of PVA/CS films while reducing their UV–vis light transparency. Additionally, the biodegradability of the biocomposites increased, reaching 74% after 30 days of soil burial. Moisture content, water solubility, and swelling decreased with LP content, favoring food preservation. It can be asserted from the tensile test that blending PVA with CS enhances the Young's modulus by 17%. The incorporation of LP into the PVA/CS blend further enhanced the Young's modulus and tensile strength to 1322 and 193 MPa, respectively, attributed to the strong hydrogen bonding between the PVA/CS matrix and LP. Moreover, PVA/CS/LP biocomposites effectively reduced weight loss in cherry tomatoes and inhibited microbial growth, suggesting their potential as eco‐friendly bioactive packaging materials for food preservation.
