Influence of Injection Pressure and Injection Timing on 4 Stroke Single Cylinder Diesel Engine Performance using Blend of Biodiesel

Biodiesel is most favorable alternative fuels for I.C engine because of its similar quality as of diesel to use in I.C engine. Now a day’s so many problems raised to use biodiesel in I.C engine such as High Nox formation, Low brake thermal efficiency, less combustion characteristics etc. In our Experiment we could minimize this kind of problems by Modified injection systems, like Increases Injection pressure (210 bar), Retard Injection timing (25° Btdc) Through all parameters Experiment were carried on Direct Injection Single cylinder C.I engine using blend of biodiesel (palm seed oil B30). Here diesel as well as Biodiesel blend with modified injection parameters are analyzed and compared with original condition of engine. During Experiment, Minimized NOx formation up to 16% in Diesel and 10% in biodiesel less than the Original condition. While SFC 3.4 % decreased in diesel, 10% increase in biodiesel and also nearest 2 % Improved Brake thermal efficiency than original condition. Both Modification condition CO and CO2 having negligible effected on Emission performance.
