The flow of air to the combustion chamber plays a vital role in complete and efficient combustion of air-fuel mixture in diesel engines. Thus, the field of air management involves various research tools like computational fluid dynamics (CFD), high resolution cameras to mention a view. The better the air flow structure, the better will be the end result. Thus, to improvise the air flow inside the combustion chamber, air has to be given whirling effect beforehand which can be done by various ways like shrouding the inlet valves’ train design, modifying the piston head to mention a few. This not helps in generating the required organized turbulence but also helps in rectifying emissions, performance and fuel economy. Therefore, in this paper, effects of different piston heads will be considered and also will arrive at the best possible shape and design of piston head for single cylinder diesel engine.
