Abstract
This study focuses on the Computational Fluid Dynamics (CFD) analysis of a two-stroke combustion engine to investigate the complex dynamics of pressure distribution, combustion progression, and fluid flow behavior. Two-stroke engines, known for their high power-to-weight ratio, are widely utilized in various applications; however, they pose challenges in terms of fuel efficiency, emissions, and scavenging performance. Using ANSYS Fluent, a detailed simulation was conducted to analyze pressure contours, combustion progress variables, and flow patterns within the engine. The results demonstrate critical insights into pressure gradient transitions, indicating effective scavenging and minimal backflow under optimized conditions. Combustion progress variable contours highlight the efficiency of air-fuel mixture burning and identify regions where incomplete combustion occurs. Additionally, flow behavior near ports and exhaust regions was analyzed to assess design efficacy and highlight areas for improvement. This research highlights the capability of CFD tools in optimizing engine performance, enabling significant improvements in fuel economy, power output, and emissions control. By providing a comprehensive understanding of the intricate processes within a two-stroke engine, this study lays the groundwork for further advancements in engine design, including modifications to port geometry, enhanced fuel injection strategies, and the integration of alternative fuels for sustainable and efficient engine operation.
