Effect of blends of two kind of biodiesel on performance and emission of single cylinder DI diesel engine

Abstract

Petroleum fuel resources are now depleting at a faster rate. Due to this reason many researchers are now attracted towards the biodiesel. India is having a large potential of Jatropha and Karanja seeds. These seeds are the source of biodiesel. More over these are not the human food grains. Refereeing to the availability at the fields these two kinds of seed fuels can be blended together as fuel instead of diesel with no any major modification in an engine. Hence main aim of this research was to blend Jatropha and Karanja biodiesel and testing these fuels for a diesel engine. Two kinds of biodiesel Jatropha and Karanja are blended in different proportions. Basically percentage of Karanja in Jatropha fuel was varied. These blends are then tested on single cylinder DI diesel engine. Results show that the Energy performance of diesel engine was deteriorated with the addition of Karanja biodiesel in Jatropha biodiesel. However emission performance was improved.
