The energy consumption throughout the world has been increasing every day. The fossil fuels are the main energy source for automobiles. The increase in the usage rate of fossil fuel proves to be a major source of greenhouse gases and air pollution. On the other hand, in the form of waste plastic, a good source of energy is dumped without any usage. Since plastic materials are non-degradable, this leads to a considerable problem in solid waste management. Waste plastic oil can be obtained through pyrolysis process of waste plastic. The physical and thermal properties of the waste plastic oil (WPO) are near to the diesel fuel. The waste plastic oil can be directly used as a fuel for unmodified CI engine. This reduces plastic waste, and it acts as a viable source of energy. In this experiment, different blends such as WPO20, WPO40, WPO60, WPO80 and neat waste plastic oil are used as a fuel in the CI engine. The performance and emission results have shown that WPO20 produces better results than the other blends of waste plastic oil. So, this blend is used for further research. Many researchers have analysed the engine characteristics using WPO as a sole fuel in CI engine, but no research has been done so far with WPO as a fuel in LHR engine. LHR engines have various advantages such that they may increase the adiabatic flame temperature, reduce the heat loss, which in turn increases the brake thermal efficiency, and reduce HC and CO emissions. The LHR engine is tested with WPO20 as a fuel, and its performance and emission values are compared with a conventional diesel fuel engine. The engine vibration is found to be reduced while using LHR engine rather than the conventional diesel fuel engine. The experiment results from LHR engine show improved BTE and reduced emissions, such as CO and UBHC, while there is a slight increase in NOx.

A growing interest in extracting oil from waste plastics has converged with rising demand for petro-fuels and issues in disposing of waste plastics. The characteristics of pyrolytic oil produced from plastic wastes were compared to diesel and found to be sufficiently similar to be used as an alternative fuel. In this paper, an attempt has been taken to enhance the combustion properties of waste plastic oil blended diesel following dispersion of nanographene particles. The performance and emissions of a single-cylinder direct injection compression ignition engine with compression ratios ranging from 16:1 to 18:1 was evaluated using 50, 70, and 100 ppm by using 50, 70, and 100 ppm by mass of nanographene dispersed in 20% waste plastic oil blended diesel without any engine modification. By supercharging the engine with nanographene at various compression ratios, the performance of a 20% plastic oil blended diesel is compared to that of a neat diesel. The brake thermal efficiency of 20% plastic oil blended 100 ppm graphene dispersed diesel fuel increased by 1.16% at a compression ratio of 17:1 when compared to diesel. The CO, HC, NOx emissions also dropped significantly by adding 100 ppm nanographene to WPO as compared to the other combinations of fuels.
