Effect of Brake Thermal Efficiency of a Variable Compression Ratio Diesel Engine Operating with Pongammia Pinnata Oil Blends Under Different Loading Conditions
Journal Title: GRD Journal for Engineering - Year 2016, Vol 1, Issue 12
Abstract
In this experimental study Brake Thermal Efficiency of a variable compression ratio (VCR) Diesel engine operating with diesel and Pongamia pinnata oil blends were studied under different five different loading conditions (0,3,6,9 & 12 kg), two compression ratio (17:01 & 18:01) and three different Pongamia pinnata oil blends (B10, B15 & B20) which are blended with diesel by volumetric basis (100 ml Pongamia pinnata oil: 900 ml pure Diesel, 150 ml Pongamia pinnata oil: 850 ml pure Diesel, 200 ml Pongamia pinnata oil: 800 ml pure Diesel) respectively. For comparative purpose initially the engine was run by pure Diesel. This study shows that the Brake Thermal Efficiency is maximum (34.14%) when the engine operates with Pongamia pinnata oil (B15 blend) which was blended with pure Diesel on full load conditions (12 kg) and compression ratio of 18:01. This study shows that the Brake Thermal Efficiency is minimum (1.31 %) when the engine operates with Pongamia pinnata oil (B15 blend) which was blended with pure Diesel on no load conditions (0 kg) and compression ratio of 17:01.
