Effects of Compression Ratio on Performance combustion and emission of a Single Cylinder 4- Stroke Compression Ignition Engine using Blends of Neat Karanja Oil with Diesel
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 2
Abstract
Compression ignition engines play the major role for the development of any country. Fossil fuel layer depletion and emissions of compression ignition engine are two challenges for the world now days. To overcome the challenges it is necessary to replace conventional fuel by alternative fuels. Now a day’s bio fuels become popular as an alternative fuel for compression ignition engines. It can be used in compression ignition engine with many difficulties. In India million tonnes non edible seeds like Karanja seeds are going in waste. . This study is performed to find the effect of compression ratio on performance parameters such as brake specific fuel consumption, brake thermal efficiency, mechanical efficiency in a single cylinder four stroke VCR engine fuelled with diesel and its blends with neat Karanja oil on volume basis (10%, 20%) and compared the results with diesel. Experiments have been conducted at compression ratios of 16:1, 17:1, 18:1. At higher compression ratio minimum value of brake specific fuel consumption (BSFC) was recorded as being 0.33Kg/kWh for 10% blend of Karana oil (K10). Maximum value of brake thermal efficiency was found to be 26.63% for K10. At higher compression ratio mechanical efficiency of diesel was higher than10% blend of Karanja oil.
