Effect of combustion chamber geometries in biodiesel fueled CI engine: A comprehensive review

Depleting fossil fuels and raise in prices day by day has paid attention to alternative fuels. Emissions are the major concern in biofuels. Stringent future emissions norms can be met with implementation of key technologies. Performance of a biodiesel fueled CI engine can be improved by some modifications in the engine. One such is the combustion chamber geometry. This paper summarizes the results of different types of combustion chamber geometry with various biodiesel. The variations in performance parameters, emissions (UBHC, CO, NOx, smoke) and combustion parameters are also discussed in detail. The summary shows that suitability of alternative fuels can be improved by selecting the proper combustion chamber geometry.
