EFFECT OF FUEL INJECTION TIMING ON PERFORMANCE AND EMISSION CHARACTERISTICS OF CEIBA PENTANDRA BIODIESEL

Abstract

Alternative fuels have received abundant attention thanks to the depletion of world fossil fuel reserves and magnified environmental issues. Within the gift paper experimental study is allotted on I.C. engine laboratory single cylinder, four-stroke tape recorder, direct injection internal-combustion engine to analyse the performance and emission characteristics of pure diesel and white silk-cotton tree blending fuels with varied blending rates. For internal-combustion engine, injection timing order arrangement is one altogether the foremost parameters that have a control on the engine performance and emissions. The measurements area unit recorded for the Injection timing order of 0°,3°,6°,9°,12° and 18°bTDC varied the load from idle to rated load of 3.5 kW. For this study, alkyl esters of Ceibapentandra Oil were intercalary to diesel by volume of 10% (B10), 20% (B20), 30% (B30) and 40% (B40). Engine performance parameters specifically specific fuel consumption, brake thermal, Indicated thermal efficiency and exhaust emissions of CO, HC, CO2, Nox were determined. The brake thermal efficiency at 100 percent load for white silk-cotton tree alkyl organic compound blends and diesel has been calculated and also the blend B10 is found to relinquish most thermal efficiency. The blends once used as fuel ends up in reduction of monoxide, organic compound and increase in chemical element oxides emissions. The engine performance and Emission parameters was found to be optimum once victimization B10 as fuel at Injection timing order 12°bTDC throughout full load condition.
