Emission standards in European Union, designed to reduce the environmental impact of power generation, present a significant challenge for fast-response distributed generation systems based on internal combustion engines. Regulated emissions, such as NOx and particulate matter major concern due their adverse number health effects. Simultaneously, Union strives towards sustainable management plastic waste seeks ways its upcycling production new fuels chemicals. As an answer presented challenges, experimental study addresses potential use chemically stabilized Waste Plastics Oil (WPO), product pyrolysis process plastics Reactivity Controlled Compression Ignition (RCCI) concept. To establish reactivity-controlled combustion, uses combination methane (a model fuel biomethane) WPO a) simultaneously emissions low local temperatures high degree charge homogenization b) address carbon footprint reduction challenges. Through experiments, influence direct injection timing energy shares utilized in-cylinder thermodynamic parameters engine emission response were evaluated operating points at constant indicated mean effective pressure. Acquired results deeply investigated benchmarked against compression ignition (CI) RCCI operation with conventional diesel determine utilization advanced low-temperature Results show that can be efficiently concept without adaptation suitable control parameters, ultra-low PM achieved fuels. For diesel/methane mix, reduced compared CI 82.0% 93.2%, respectively, whereas WPO/methane 88.7% 97.6%, which ascribed favourable chemical characteristics In least point among those studied, pressure covariance was kept below 2.5%, is well 5% being considered limit stable operation.
