Energy Intensities

Work is based on the impact of air swirl in the cylinder chamber by cfd analysis of a one cylinder 4s CI engine is presented. So as to accomplish the swirl, tumble and kinetic energy intensities in the combustion chamber. The cylinder head is modified to increase the turbulence in the chamber. This increases the air motion, is done by removing material and protrusion on the cylinder head. Depending upon on the design configurations of Diesel engine i.e. in the order to exaggerate the air motion and to provide homogenous mixture in the cylinder and its effects on the emission and performance.

The Impact

Experimental work was done to examine the impact of diesel fuel with alumina nanoparticles on combustion characteristics, emissions and performance of diesel engine. Alumina nanoparticles were mixed with crude diesel in various weight fractions of 20, 30, and 40 mg/L. The engine tests showed that nano alumina addition of 40 ppm to pure diesel led to thermal efficiency enhancement up to 5.5% related to the pure diesel fuel. The average specific fuel consumption decrease about neat diesel fuel was found to be 3.5%, 4.5%, and 5.5% at dosing levels of 20, 30, and 40 ppm, respectively at full load. Emissions of smoke, HC, CO, and NOX were found to get diminished by about 17%, 25%, 30%, and 33%, respectively with 40 ppm nano-additive about diesel operation. The smaller size of nanoparticles produce fuel stability enhancement and prevents the fuel atomization problems and the clogging in fuel injectors. The increase of alumina nanoparticle percentage in diesel fuel produced the increases in cylinder pressure, cylinder temperature, heat release rate but the decreases in ignition delay and combustion duration were shown. The concentration of 40 ppm alumina nanoparticle is recommended for achieving the optimum improvements in the engine’s combustion, performance and emission characteristics.
