Experimental investigation of performance, emission and combustion characteristics of waste plastic pyrolysis oil blended with diethyl ether used as fuel for diesel engine

Considering the amount of waste plastics has risen significantly, energy may be extracted from it. Not only is it possible to dispose of waste plastics by converting them to fuel, but it is also possible to extract energy from them. Our research is motivated by the prospect of using waste plastics as a source of energy through waste plastic pyrolysis oil (WPPO). The innovation of this research is that it will assess the efficiency of plastic pyrolysis oil derived from Low-Density Polyethylene (LDPE) on a Thermal Barrier Coated (TBC) piston engine. The incremental ratio of WPPO to pure diesel with the addition of diethyl ether (DEE) was determined and its output and exhaust emission standards were evaluated using a direct injection single cylinder low heat rejection diesel engine. The results for the WPPO blends were promising as with TBCW20DEE10 demonstrating a 5 to 15% increase in carbon monoxide under different load conditions. TBCW20DEE10 confirmed a greater reduction of hydrocarbons varying from 5 to 12 %. At half load condition, TBCW20DEE10 emits approximately 3.5 % less unit of smoke.

This experimental investigation is an endeavour to substitute diesel with WPO as fuel on a diesel engine. Enhancing the physiochemical properties of WPO or with hardware modifications on the engine, the performance of engine could not be improved up to the mark. The physiochemical properties of WPO are enhanced by the use of composite additive, which is a mixture of soy lecithin and 2-ethylhexyl nitrate and to improve the in-cylinder air motion; subsequently to increase the swirl and turbulence, standard hemispherical combustion chamber is modified to toroidal spherical grooves combustion chamber. The results of combined effect of modifying the combustion chamber and addition of composite additive suggest that improvements in engine-out emissions can be obtained from current diesel engines by enhancing physiochemical properties of fuel and matching geometry of combustion chamber. Engine combustion and emission characteristics under various loads for various fuels under test are as well studied.
