Biodiesel has emerged as a compelling substitute for conventional diesel fuel, providing sustainable and eco-friendly choice fueling compression ignition engines. This comprehensive study investigates the influence of biodiesel, specifically derived from sunflower oil, through esterification method, on crucial engine performance parameters environmental effects. The examines impact varying torque single-cylinder, four-stroke engine, encompassing such brake thermal efficiency (BTE) specific fuel consumption (BSFC), well exhaust emissions, including unburned hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx). Four distinct biodiesel blends (B10, B20, B30, B40) with oil content are systematically compared to pure (B0). operates at consistent speed 1700 rpm, while undergoes controlled adjustments 0 10 Nm. Subsequently, this explores application an alternating model tree (AMT) machine learning algorithm establish relationships between independent factors, volume (%vol), dependent variables, BTE, BSFC, CO, NOx in combustion engine. Additionally, employs multi-objective ameliorative whale optimization (AWOA) optimize model's output. objective is identify optimal values %vol that maximize minimizing emissions (CO NOx) reducing (BSFC). process yields noteworthy results, AWOA achieving peak BTE 29.714%, BSFC 0.262 kg.kWh-1, 992 ppm 7.3 N.m 13% vol. In contrast, particle swarm (PSO) secured minimum CO level 0.123%, set 7.6 26% AMT models demonstrate high prediction accuracy, coefficient determination (R2) exceeding 0.98.

Abstract This research examines the performance variables, combustion, and amounts of NOx, CO, HC, K emissions in a diesel engine, using blends hemp biodiesel oleic acid with conventional diesel. To obtain from oil acid, heterogeneous sulfonated camphor catalyst (CASU-AL) was used for transesterification esterification respectively. Several characterization tests were performed on CASU-AL such as acid-base titration method quantification sites, XRD analysis to determine areas carbonaceous material, images composition obtained SEM EDX, porosity characteristics surface properties assessed BET analysis. Constant operating conditions autogenous reactor temperature 200 °C, reaction time 23 min, quantity 0.033 % w. analyses applied CASU-AL, several mixtures made diesel, different biodiesels laboratory. The (DIE-100), (BAC-100), (BAO-100), Diesel-BAC mixture 30 (MDBAC-30), Diesel-BAO (MDBAO-30). For three speed zones selected engine identify behavior at low 1,200 rpm, medium 1,400 high 1800 rpm. Combustion reveal that no significant variation is observed however, gaseous products derived reductions carbon monoxide, unburned hydrocarbon, an increase nitrogen oxide achieved when DIE-100 compared BAC-100 BAO-100. showed reduction K, smoke testing MDBAC-30 MDBAO-30 laboratory engine. A comparison oil-oleic BAO-100 revealed could be alone or blend 70 fuel engines by decreasing air pollutants promoting lubricity Our findings best lowest among all tested fuels. In other words, are ideal do not require any modification

Epidemiological studies have consistently linked air pollution to severe health risks. One strategy reduce the impact of combustion products from engines is adding additives fuel. Potential benefits been observed in terms performance and emissions, as well decreasing fuel consumption. However, associated emission particulate matter into environment may unforeseen effects. This study examines effects diesel exhaust particles (DEPs) mixed with amide-functionalized carbon nanotubes (CNTF). The aim analyze properties DEPs determine their toxic on lung cells. were characterized using scanning transmission electron microscopy, while polycyclic aromatic hydrocarbons (PAHs) analyzed through gas chromatography. Various assays conducted assess cell viability, apoptosis, oxidative stress, DNA damage. addition CNTF altered morphology size particles, quantity composition PAHs. At cellular level, induce higher levels reactive oxygen species (ROS) production, damage, cytotoxicity compared both diesel–CNTF DEPs. These findings suggest that nano-additives enhance energy efficiency by reducing pollutants without significantly increasing toxicity.
