摘要

The results of comprehensive computational studies on converting the Renault k9k 1.5 dCi automotive diesel engine and the Rotax 914 aviation gasoline engine from a four-stroke to a two-stroke operating cycle are presented. The calculations were performed using the AVL BOOST and AVL FIRE software suites developed by the research company AVL. The first program enabled the selection of optimal engine settings, primarily valve timing. The second, through three-dimensional numerical simulation, demonstrated the possibility of necessary cylinder scavenging via poppet valves in the two-stroke cycle with the selected valve timing. The calculations confirmed the potential for a significant increase in engine power and torque (by a factor of 1.5–1.8) across the entire operating crankshaft speed range. These results are supported by experimental data published in well-known studies.
