Optimization of Injection Pressure and Compression Ratio of Vcr Ci Engine Fueled with Waste Plastic Oil Blended with Diesel

Running down of fossil fuel reserves increased the need of alternative fuels which can be capable to meet the energy demand of today's world. Plastic is indispensable material, non-biodegradable and has wide range of application in the industrial field. In this perspective, as an alternative, waste plastic oil drags the attention of the researchers and it is renewable fuel because of huge availability of waste plastic. The properties of the waste plastic oil extracted from pyrolysis are compared with petroleum products and found that it has similar properties to that of neat diesel fuel. In this work, conversion of waste plastic to alternate fuel, blending with petro diesel (WP010,WP020) had done, and analyzed their performance, combustion and, emission parameters on a single cylinder VCR CI Engine at different compression ratios (14:1,16.5:1,19:1) and at different injection pressures (200,220,240bar), and came out with optimum results at 19:1CR and 240 bar Injection pressure
