Eichhornia crassipes biodiesel as a renewable green fuel for diesel engine applications: performance, combustion, and emission characteristics.

This work examines the feasibility of fuelling biodiesel derived from Eichhornia crassipes in a compression ignition engine. This work also proposes water hyacinth biodiesel (WHB) as a potential alternative energy source since the above species is available extensively in freshwater, marine, and aquatic ecosystems throughout the world. WHB was blended with petroleum diesel fuel at various volume proportions of 10%, 20%, 30%, 40%, and 100% and their properties were analyzed as per ASTM standards for its application as biofuel.

An experimental assessment on the influence of fuel-borne additives on ternary fuel (diesel-biodiesel-ethanol) blends operated in a single cylinder diesel engine.

The present work is dedicated to the experimental analysis on the influence of fuel-borne additives on ternary fuel blend operated in a single cylinder DI diesel engine. Alumina (AlO) nanoparticles were chosen as fuel additives at dosing levels of 10, 20, and 30 ppm, respectively, and the ternary fuel (TF) is prepared by blending 70% diesel, 20% Jatropha biodiesel, and 10% ethanol. Performance characteristics like brake thermal efficiency (BTE) and brake-specific energy consumption (BSEC) and emission characteristics like HC, CO, NOx, and smoke along with combustion characteristics like cylinder pressure, HRR (heat release rate), and CHRR (cumulative heat release rate) were considered for analysis.

Combined impact of EGR and injection pressure in performance improvement and NOx control of a DI diesel engine powered with tamarind seed biodiesel blend.

In the process of creating eco-friendly environment and conserving fossil fuels for the future generations, biodiesel has been chosen as a good substitute for diesel. It is a proven fact that biodiesel operated diesel engine can deliver comparable results with diesel. The present work focuses on TSME20 (tamarind seed methyl ester 20% + diesel 80%) as a renewable fuel, and its performance and emission results are analyzed at different exhaust gas recirculation rates and various injection pressures.

Improvement of ternary fuel combustion with various injection pressure strategies in a toroidal re-entrant combustion chamber.

The present experimental work focuses on the influence injection pressure and toroidal re-entrant combustion chamber in a single cylinder diesel engine fuelled with ternary fuel (diesel-biodiesel-ethanol) blend. Ternary fuel (TF) is prepared by blending 70% diesel, 20% biodiesel, and 10% ethanol blends and its fuel properties were investigated and compared with diesel fuel. Since the physic-chemical properties of TF are well behind the diesel fuel, it is proposed to be blended with 20 ppm alumina nano additives which act as an ignition enhancer and catalytic oxidizer.
