As the world moves away from fossil fuels and embraces sustainable energy sources, need for transportation becomes paramount. This study investigates effects of pyrolysis oil derived cassava peel waste (CPO), hydrogen (H), diesel (D) blends as a partial substitute low-displacement compression ignition engines. We tested three – CPO25, CPO25H5, CPO25H10 against neat operation at engine speeds 3400 rpm, 3600 3800 rpm torques 4 Nm, 6 8 Nm. Our findings reveal that while efficiency decreased with CPO25 compared to D100 operation, adding H2 increased efficiency. The highest increase was 7.8 % CPO25H5 16 CPO25. Exergy also D100, but compensated this reduction. 8.0 17 D100. showed an 8.1 in combustion pressure 9.9 heat release rate Emissions analysis revealed CO emissions were considerably lower CPO than decrease 11 CPO25H10. CO2 hydrocarbon followed same trend CO. Although NOx slightly increased, benefits using oil-H2-diesel substitution fuel engines are evident.

Fossil fuels confront the problem of strategic resource depletion since they have been continuously utilized for more than 200 years and cause serious damages to ecological environment planet. In this work, transesterification castor plant oil was make biodiesel, biodiesel’s physicochemical qualities were assessed. On a single-cylinder, four-stroke, water-cooled agricultural diesel engine, an experimental study conducted compare analyze engine performance emission characteristics biodiesel blends in various amounts. The B20, B40, B60, B80 evaluated at different speeds (1200, 1400, 1600, 1800 rpm) with constant load (50%). According findings, brake thermal efficiency (BTE) declines as speed rises, fuel blend has lower because its higher density viscosity calorific value. amount gasoline required create power increases does, brake-specific consumption (BSFC) trend is upward. Due their low value high properties, greater diesel. fuel’s exhaust gas temperature (EGT) upward increased rotational speed. blend’s cetane number shortens ignition delay lowers compared A oxygen added, enhances combustion, combustion temperature, up oxidation process, carbon monoxide (CO) hydrocarbon emissions. produces lowest emissions rpm, 0.33%, 30 ppm, respectively. other hand, dioxide (CO2) result from concentration. addition, fuel, causes creation nitrogen oxide (NOx) research excellent alternative engines it can be directly without modifying current construction good performance.

Abstract The objective of the present investigation is to enhance performance diesel engine using Capparis spinoza fatty acid distillate biodiesel (CFAB100) at various compression ratios. experiments were carried out ratios 16.5:1, 17.5:1, 18.5:1, and 19.5:1. It was noted that an increase in ratio from 16.5 18.5 resulted better characteristics for CFAB100 reduced 19.5. Brake-specific fuel consumption decreased 0.42 0.33 kg/kWh with ratio. brake thermal efficiency a 29.64% lower than diesel, whereas it 11.32% low 18.5. 26.03% higher compared 16.5. Due shorter ignition delay premixed combustion, net heat release rate all peak cylinder pressure 56.21 bar, 16.5, 17.5, 18.5, 19.5 52.36, 55.12, 61.02 58.25 bar full load condition. CFAB100, had highest nitrogen oxide emissions (2400 ppm). Carbon monoxide, unburnt hydrocarbon, smoke showed average reduction 46.58%, 40.68%, 54.89%, respectively, when varied between At optimum improved emission can replace possible extent.

The diesel engine’s superior energy conversion efficiency and cost-effective power source have made it a popular choice for wide range of applications, including but not limited to agricultural machinery, transportation, mining equipment. Diesel engines produce harmful emissions, exhaust fumes that contain pollutants such as particulate matter nitrogen oxides. These emissions are detrimental the environment public health, result, strict standards imposed reduce them using modern technologies in engine manufacturing, treatment systems improvement fuel modifying technologies. This chapter reviewed effect verity performance emission.

The novelty of the present work deals with experimental investigation on effects varying injection pressure (IP) CI engine characteristics using a novel Ceiba pentandra biodiesel at 20% by volume (B20). key objective this study is to enhance increasing IP fuel blends without any major modifications This strategy could improve performance as higher resulted in improved atomization and better air-fuel mixing. From experimentation it was found that combined blend (B20) (260 bar) increased BTE (9%), CP (8.5%), HRR (2%) reduced BSFC CO (14%), HC (16%), Smoke (16%) than diesel (B0) standard 200 bar. To overcome challenges NOx emission IP, exhaust gas recirculation (EGR) technique also implemented lower rates. With effect 15% EGR, there subsequent 29% reduction NO x achieved affecting other emissions trade-offs.
