In modern society where fossil fuel prices are increasing and environmental issues becoming more severe, biodiesel, as a new type of clean fuel, is receiving attention. Biodiesel has the advantages renewability, friendliness, good properties, demonstrating broad application prospects. However, use biodiesel also faces some challenges, such higher density kinematic viscosity, lower calorific value, etc. The nanoparticles in engines helps to achieve goal fuel. terms characteristics, increase cetane flash point improving combustion efficiency safety, but may affect combustion. can promote micro explosions secondary atomization improve cylinder pressure, heat release rate, brake thermal while reducing consumption. Nanoparticles reduce HC CO emissions, through oxygen reaction area, incomplete products. On contrary, CO2 emissions because better conditions oxidation reactions. For NOX temperature others emissions. Comparison shows that all offer varying degrees improvement engine performance provided by TiO2 significantly than other nanoparticles. future, synergistic effect multiple should be explored further achieving effects cannot achieved single nanoparticle.

The use of biodiesel as an alternative to conventional diesel fuels has gained significant attention due its potential for reducing greenhouse gas emissions and improving energy sustainability. This study explores the impact TiO2 nanoparticles on emission characteristics combustion efficiency blends in compression ignition (CI) engines. analyzed include diesel, SB20 (soybean biodiesel), + 50 ppm, 75 PB20 (palm ppm. Experiments were conducted under a consistent load 50% across engine speeds ranging from 1000 1800 RPM. While have been widely recognized their ability enhance properties, limited research exists specific effects soybean palm biofuels. addresses these gaps by providing comprehensive analysis emissions, including NOX, CO, CO2, HC, well exhaust temperature (EGT), various nanoparticle concentrations. results demonstrate that lead reduction CO up 30% HC 21.5% at higher concentrations speeds. However, this improvement is accompanied 15% increase CO2 indicating more complete fuel oxidation. Additionally, NOX which typically with speed, mitigated 20% addition nanoparticles. Exhaust temperatures (EGTs) also lowered, enhanced stability. These findings highlight optimize improved environmental performance CI
