Abstract

The increase of emissions from fuel causes environmental pollution and several health issues. In this experimental exploration Mahua methyl ester with SiO₂nano additive diesel blends characteristics of compression ignition (CI) engine were examined to reduce pollution which aligns with sustainable development goals like SDG 3: Good Health and Well-being, SDG 7: Affordable and Clean Energy, and SDG 13: Climate Action. Based upon the previous literature, up to 20% mahua methyl ester fuel blends without nano additives are suitable for CI engines without disturbing the engine features. In this paper SiO₂nano additive dopped into the B40 (40% mahua biodiesel- diesel) blended at the rate of 50 ppm for developing the test fuels. The SiO₂ nano additive blends improve the properties like viscosity, calorific value, and decrease the flash point and fire point. The observation of results, 40 MEOM + 50 ppm dopped fuels, improved the brake thermal efficiency (1%), the emissions like CO, HC, CO₂and smoke are slightly decreased and slightly increased NOx emissions. The combustion characteristics like maximum pressure rise, heat release rate is increased (1%) compared to other fuel combinations. The results are considered, a blend of 40 MEOM+ SiO₂ 50 ppm is the best blend ratio.
