Fuel Injection Strategies in Diesel Engines

In DI diesel engine, swirl ratio plays an significant role for better air-fuel mixture interaction, with decrease in combustion duration for Off-set chamber at different at different fuel injection strategies. For promoting better mixing squish flow induced with compression combined with swirl interaction increases disorganised mixing in the combustion chamber. Since flow of fluid within the combustion chamber is developed based on the interaction of suction process with in the in-cylinder geometry. The purpose of carrying out this research is to emphasize the role of bowl-in-piston geometry on in-cylinder fluid flow, combustion analysis and pollutant formation process. The objective of the present research is to develop a in-cylinder multi-dimensional fluid flows which can predict in-cylinder fluid motion behavior by using different piston-bowl geometries.The combustion and emission related parameters that are going to be analyzed are:a) Different Piston bowl geometries b) Variable Injection timingc) Split injectiond) Mass-averaged Pressure and temperature variations inside the cylinder.e) NOx and soot distribution inside the cylinder.
