Summary:

AbstractAir motion in a cylinder in a compression ignition engine affects on mixing of air-fuel, quality of combustion and emission produced. With upcoming stringent norms for diesel engines, it is necessary to enhance air-fuel mixing for proper combustion. Swirl and tumble are forms of air motion. Swirl is a rotational motion of a bulk mass within cylinder. Swirl is generated by shaping and countering intake manifold and valve portraits Swirl enhances air-fuel mixing and helps to spread flame-front during combustion.The objective of this paper is to analyze the impact of different swirl ratios on NOx and soot emission characteristics inside the cylinder of a DI Diesel engine. The effects of different geometrical parameters of helical port were studied and the swirl ratios are optimized by optimizing the geometrical parameter of helical portrait This can be done by different manufacturing, polishing and grinding processes. The designed inlet port were then validated by measuring swirl on AVL paddle wheel anemometer and the experiments were conducted on these inlet ports of different swirl ratios and validate the NOx and soot emissions as per emission norms BS IV. Positive results have been observed and the data has been shared in paper
