“…This is due to a low calorific value of WPO used in their experiments. In order to reduce BSFC and increase the thermal efficiency of the engine, some modification of the operating parameters can be done such as the injection timing and the injection pressure [9]. When the injection timing is retarded from 23 o bTDC (before top dead center) to 14 o bTDC, the BSFC was found to be lower while the thermal efficiency was found to be higher.…”

“…Therefore, some modification should be conducted to enhance the engine performance. Waste plastic pyrolysis oil which is produced from the pyrolysis of waste plastics, can be used as an alternative fuel for substituting petroleum-based fuel due to the abundant sources of waste plastics [9][10][11]. Diesel engines as one of the internal combustion engines which are widely used either in an automotive vehicle or in power plant have a high potential for employing plastic oil as a fuel.…”

“…The thermal efficiency was found to be higher up to 75% of the rated power. The blending of plastic oil with diesel fuel has also been studied by some researchers [9,10,16]. The performance and emission of plastic oil in a diesel engine strongly depend on the chemical composition and the physical properties of the plastic oil.…”

This study aims to utilize pyrolysis oil produced from the pyrolysis of waste polyethylene in a direct injection (DI) diesel engine. In this paper, the performance and emission of a diesel engine have been studied using blends of waste polyethylene pyrolysis oil with diesel fuel under different loads condition. The waste polyethylene pyrolysis oil (WPO) used in this work was produced from the sequential pyrolysis and catalytic reforming of polyethylene bag after crushing and washing using natural zeolite (NZ) catalyst. Engine tests have been done using a four-cylinder and four-stroke diesel engine with the compression ratio of 22 and water cooling system. The experimental works were done at the rated engine speed of 1800 rpm. The results indicated that the brake thermal efficiencies are slightly higher as compared to that of diesel while the brake specific fuel consumption (BSFC) is slightly reduced when blending diesel fuel with WPO. Moreover, WPO-diesel fuel blends at various engine loads are also found to have influences on the emissions of CO, HC, NOx, and the smoke opacity. The NOx emission is found to be lowered by blending diesel with WPO. The decreased NOx emission is due to the decrease of the in-cylinder temperature by the effect of the non-homogeneity of WPO. The emissions of HC and CO of WPO-diesel blends are higher than that of diesel. Finally, the smoke opacity for WPO blends is slightly higher at higher loads.

“…The HC, CO emissions are less and NOx is higher for biodiesel blends operated engine. This higher NOx emission can be controlled by using EGR technique with optimum EGR rate, but this increases the HC, CO emissions (Sakhare et al, 2016;Daniel et al, 2016;Daniel et al, 2015). At 15% EGR, cylinder pressure and HRR are higher for biodiesel when compared to diesel fuels (Anandavelu et al, 2011;Gowthaman et al, 2015).…”

Effort towards prospective utilization of dairy waste scum oil methyl ester (DSOME) is extremely pronounced as a promising sustainable unconventional fuel for diesel engine as they have intrinsic oxygen content emits less HC and CO emission and contradictorily increases the NOx. In this regard, the present study elucidates the influence of engine exhaust gas recirculation (EGR) on diesel engine performance, combustion and emission characteristics operated with DSOME-B20 (20% dairy scum biodiesel, by volume). The brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) are appreciably improved for 5% and 10% EGR in comparison with 15% EGR rate. Mainly, about 49-57% of NOx can be reduced with 5-15% EGR rate but increasing EGR rate more than 10% dilutes the fresh intake air hence reduces the NOx and increases the HC, CO emissions. Hence use of 5-10% EGR in diesel engine is advantageous to get considerably improved performance and reduced HC, CO and NOx emissions.

“…[10][11][12] were run the diesel engine blended with plastic oil to evaluate the performance and emission characteristics without any engine modificat ions, their investigation clears that the plastic oil is alternate fuel for d iesel engine. [13][14][15][16][17] are experimentally investigated on a diesel engine using waste plastic oil and tyre o il blends with exhaust gas recircu lation. Their results shows that plastic and tyre oil blended engines suffers with high NO x emission, which can deduced by using exhaust gas recircu lation.…”

Abstract. In the present work, an experimental investigation is carried out to evaluate the use of plastic oil derived from waste plastic which used in a Spark Ignition engine. Experiments are conducted, the measured performance and emissions of plastic oil blends at different proportions are compared with the baseline operation of the SI engine running with gasoline fuel. Engine performance and exhaust gas emissions such as carbon monoxide, total unburned hydrocarbons, carbon dioxide and oxides of nitrogen are measured. From the experiments it is observed that 50% Distilled Plastic Pyrolysis Oil (50%DPPO) exhibits the substantial enhancement in brake power, brake thermal efficiency and reduction in brake specific fuel consumption running at full load conditions among different blends and pure petrol. T here is also noticed decrement of carbon dioxide and un burned hydrocarbons emissions at the same blend. T he experimental result shows that plastic oil shall conveniently be used as a substitute to gasoline in the existing SI engines without any modifications.
