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. This study tested different exhaust gas recirculation (EGR) levels of ۰%, ۵%, ۱۰%, and ۱۵% using a modified PFI-HCCI computerised ۴-stroke, single-cylinder, water-cooled, direct injection Kirloskar diesel engine connected to an eddy current dynamometer. Furthermore, an engine running at ۱۵۰۰ rpm and a constant pre heated air temperature (PHAT) of ۱۴۰°C were assessed. In this experiment, fuel, ۲۰% biodiesel waste plastic pyrolysis oil (WPPO), and continuous PHAT ۱۴۰°C are used. The testing results show that the cylinder peak pressure and heat release rate for WPPO ۲۰ with ۱۵% EGR were attained at ۳۹.۷۰% and ۱۵.۰۹%, respectively. Additionally, port fuel injection with PHAT and WPPO ۲۰% without EGR is reported to have a ۴۵% higher brake thermal efficiency at full load than PFI-HCCI Diesel (D۱۰۰). But when employed at full load with ۱۵% EGR, WPPO ۲۰ blend also reduced smoke opacity by ۳۰.۷۴% and Oxides of Nitrogen (NOx) emission by ۵۲.۱۷%. On the other hand, compared to the PFI-HCCI (D۱۰۰), there are higher emissions of carbon monoxide (CO) (۲۲.۰۷%) and unburnt hydro carbon (UHC) (۵۴.۱۴%) with ۱۵% EGR. Consequently, WPPO can be used to the PFI-HCCI engine.
