Combined Effect of Compression Ratio, Injection Pressure, and Injection Timing on Performance and Emission of a DI Compression Ignition Engine Fueled with Diesel–Aegle Marmelos Oil–Diethyl Ether Blends Using Response Surface Methodology

Abstract

Renewable energy research in the support of generously developing choice for diesel fuel automobiles has been concentrated because of environmental causes and hurly-burly into petroleum combat. The test has been conducted in a light-duty single cylinder variable compression ratio (VCR) naturally aspirated multi fuel research engine. Three input parameters are compression ratio (CR), injection pressure (IP) and injection timing (IT) are taken as input amends. In this study parameters are taken as 16, 17, 18 for CR and 210bar, 230bar, 250bar for IP and 21°, 23°, 25° before top dead center (bTDC) for IT. The experimental trials have been planned via statistical tool like design of experiments (DoE) to outline the resulting output such as performance and emission. The better performance and lesser exhaust pollution are the desirable output factors by optimizing the injection system and compression ratio parameters by factorial design. The confirmatory tests validated that the models developed using response s...
