Modeling and Emission Analysis of a Wankel Internal Combustion Engine through EES Software

The objective here is to assess the thermodynamic and environmental performance of Wankel engines, a distinctive internal combustion engine (ICE), by applying rotary design advantages. Unlike traditional reciprocating engines, Wankel engines due to their lower combustion chamber temperatures and pressure ratios exhibit unique emission profiles. Thermodynamic modeling through EES software is applied to simulate this Wankel engine’s operation and compare its performance with conventional four-stroke reciprocating engines. The innovations here are analyzing the combustion parameters impact, on the chamber temperature exceeding ۱۸۰۰ K, on reducing greenhouse gases like CO₂ and NO₂, and evaluating water or steam injection methods to balance NOx and CO emissions. The optimization strategies for emission reductions through hydrogen and biofuels are assessed here. These findings provide new insights into enhancing the efficiency and sustainability of Wankel engines, offering practical implications for the development of cleaner combustion technologies.
