“…Therefore, the disposal of plastic debris has become a critical challenge nowadays. Depending on local restrictions, land lling and open dumping, ocean dumping, incineration, and recycling are the common approaches used to dispose of plastics (Damodharan et al 2018;Tulashie et al 2019). However, these methods result in several economic and environmental concerns.…”

With increasing population, modernization, and industrialization, plastics usage is growing daily and results in vast plastic waste. Recycling these plastic wastes to hydrocarbon fuels is challenging due to their different chemical structures, long-chain polymeric compositions, and decomposition/thermal behavior. In the present manuscript, the pyrolysis of domestic plastic waste was carried out at 473 - 973 K in a fixed bed tubular reactor and compared with individual virgin plastics, i.e. HDPE (High-density polyethylene), LDPE (Low-density polyethylene), PP (Polypropylene), and their mixture of (virgin mixed plastic). The experiments were also performed using a low-cost catalyst (mineral clay) to maximize hydrocarbon fuels. At identified optimum operating conditions, the domestic plastic waste and mixed virgin plastics yielded 73.1 wt% and 81.6 wt% liquid hydrocarbons along with 16.9 wt% and 25.5 wt.% pyrolysis gas, respectively. The composition of liquid fuels was analyzed using FTIR and GC-MS in detail, revealing a wide variety of hydrocarbons disbursement in the range of C8–C20. In addition, fuel properties of liquid fuels such as viscosity, density, fire and flash point, pour point, and calorific value was analyzed according to ASTM methods and found to be satisfactory. Based on chemical composition and fuel properties, liquid fuels derived from domestic plastic wastes showed 78.05%, and 61.86 % similarity with diesel, and jet fuels respectively. Non-condensable gases, which mainly consist of ethane and propene with minor amounts of hydrogen and methane, have been identified to be ideal for spark-ignition engine (SI) engines. This study offers a unique technique for converting waste plastics into transportation jet fuel using an affordable catalyst.

“…Several studies were found for the effect of EGR on a conventional single-cylinder diesel engine's performance and emission aspects. 17 Damodharan et al 18 and Krishnamoorthy et al 19 have examined the EGR effect on the engine's overall measurable characteristics. Also, the authors optimized the combustion parameters along with EGR during the study.…”

Limited fuel capacity and pollution are major concerns in the automobile industry. Methods to tackle these issues are continuously being investigated. The present work represents the experimental evaluation of a turbocharger and exhaust gas recirculation's (EGR's) combined effect on the common rail direct injection (CRDI) small diesel engine's performance and emission attributes. The fuel handling CRDI system variables, such as injection pressure, split injection timing, and fuel injection quantity along with EGR and turbocharger technology were considered for the study. Experiments were conducted with and without EGR and turbocharger conditions. Efforts are made to correlate the performance and emission characteristics with and without EGR and turbochargers. A combination of turbocharger and EGR shows much more lowering in nitrogen oxides, carbon monoxide, and hydrocarbon emission at the cost of a slight rise in smoke percentage. The thermal efficiency and fuel economy of the engine show a significant improvement for the turbocharger system. Overall, turbocharger and EGR combinations positively impact the engine

“…The brake specic fuel consumption (BSFC) also improved by 3.2% at higher loads. 12,13 The pyrolysis process was conducted with waste tyres at a maximum temperature of 500 C in the presence of nitrogen gas (carrier gas) in the pyrolysis reactor to obtain the waste tyre pyrolysis oil. Experimental investigations were carried out at various loads with a 10% blend of waste tyre oil.…”
