چکیده
This article describes an experimental study on fueling the port fuel injection homogeneous charge compression ignition (PFI-HCCI) combustion engine with plastic oil that is generated from waste plastics through the pyrolysis method. The study tested different exhaust gas recirculation (EGR) levels of 0%, 5%, 10%, and 15% using a modified PFI-HCCI computerized 4-stroke, single-cylinder, water-cooled, direct injection Kirloskar diesel engine connected to an eddy current dynamometer. Furthermore, an engine running at 1500 rpm and a constant preheated air temperature (PHAT) of 140°C were assessed. In this experiment, fuel, 20% biodiesel waste plastic pyrolysis oil (WPPO), and continuous PHAT 140°C are used. The testing results show that the cylinder peak pressure and heat release rate for WPPO 20 with 15% EGR were attained at 39.70% and 15.09%, respectively. Additionally, port fuel injection with PHAT and WPPO 20% without EGR is reported to have a 45% higher brake thermal efficiency at full load in comparison to PFI-HCCI Diesel (D100). But when employed at full load with 15% EGR, the WPPO 20 blend also reduced smoke opacity by 30.74% and Oxides of Nitrogen (NOx) emission by 52.17%. On the other hand, compared to the PFI-HCCI (D100), there are higher emissions of carbon monoxide (CO) (22.07%) and unburnt hydrocarbon (UHC) (54.14%) with 15% EGR. Consequently, WPPO can be used for the PFI-HCCI engine.
