Esterified Papaya Oil and its Blends as a Fuel on Single Cylinder Diesel Engine with Standard and Coated Piston
Main Article Content
Abstract
The gradual depletion of non-renewable fossil fuels, increase in their price, the toxic exhausts emitted during their combustion, risk associated in their import and its storage made many researchers to focus on deriving suitable alternate fuels. In the present investigation the performance and emission characteristics of the blends and neat methanolized papaya oil were determined on a test engine consisting of single cylinder fuelled by diesel and running at 1500 rpm. The results revealed that the blend B25 of the test biodiesel is found optimum, as it recorded better specific fuel consumption and brake thermal efficiency. Further coating on the piston enhanced the performance of the optimum blend when compared with the standard engine.
