ABSTRACT
Environmental degradation and depletion of oil reserves are matters of great concern around the globe. Developing countries like India depend heavily on crude oil import of about 125 Mt per annum (7:1diesel/gasoline). Diesel being the main transportation fuel in India, finding a suitable fuel alternative to diesel is an urgent need. In this context, pyrolysis of waste plastic solid is currently receiving renewed interest. Waste plastic pyrolysis oil is suitable for compression ignition engines and more attention is focused in India because of its potential to generate large-scale employment and relatively low environmental degradation. In the present work the performance and emission characteristics of a single cylinder, constant speed, and direct injection diesel engine using waste plastic pyrolysis oil blends as an alternate fuel were evaluated and the results are compared with the standard diesel fuel operation. Results indicated that the brake thermal efficiency was highercompared to diesel at part load condition. Carbon monoxide, Carbon dioxide and hydrocarbon emissions were higher and oxygen emission was lower compared to diesel operation.
