In Agricultural field, technological research and efforts have focused in efficiency and performance of Diesel engine, Applications of diesel engine research increasing computational power of modern computers, multi-dimensional Computational Fluid Dynamics (CFD) has found much used, design and development. Various successful applications have proven the reliability of using multi-dimensional CFD tools to assist in diesel engine research, design and development. By using CFD tools effectively it is easy to predict and analyze various details that are technically difficult like in cylinder process of diesel combustion, temperature & pressure contours emission etc. prior to experimental tests to reduce the number of investigated parameters as well as time and thus costs.

The effect of combustion chamber geometry on engine performance and exhaust emissions has been investigated in the past, since with the proper combustion chamber design significant benefits can be achieved regarding the reduction of pollutant emissions, without affecting seriously the engine performance this difficulty can be overcome by using CFD studies. This type of simulation models are identical for this purpose, since they manage to predict the effect of combustion chamber geometry on the physical and chemical processes taking place inside the combustion chamber, without the need of using empirical relations, as done for example in phenomenological models, identified different geometry configurations and noticed the trends of the produced NOx and soot, while changing some basic combustion chamber parameters. 

This book Is based on lots of valuable project’s future scope satisfaction and validate with Diesel engine manufacturer industrial experimental data for and way to produce perfect result and high performance related geometrical change in DI combustion process and effect.
