Performance of Diesel Engine With Blend and Preheated Jatropha, Thumba and Undi using Waste Heat of Exhaust

internal combustion engines especially of the compression ignition (CI)-type play a major role in transportation, industrial power generation and in the agricultural area. There is a need to search and find ways of using alternative more fuels, which are preferably renewable and also emit low levels of gaseous and particulate pollutants in internal combustion engines, low emission of waste gases the rapidly depleting conventional petroleum resources have promoted research for alternative fuels for internal combustion engines. The present objective of this project is to check various performance and emission parameters of a diesel engine, that whether Jatropha, Thumba and Undi oils can be a possible replacement to current diesel crises. The performance and emission evaluation was conducted on a diesel engine using blends of Jatropha, Thumba, Undi biodiesels and neat preheated Jatropha, Thumba and Undi biodiesels and the taken exhaust gas emissions of NOx, CO, CO2, and HC were analyzed under different load.
