摘要
The performance of the two-stroke engine depends on the scavenging process, which affects air-fuel mixture and combustion. This paper presents results from experiments in which the timing of exhaust valve opening and closing was varied in two-stroke marine diesel engine during shop testing, and reveals the effect on performance and emission, as well as the corresponding concept analysis. A simulation model was then developed based on AVL BOOST and experimental results, its validity was confirmed by actual measurements. This simulation enables a more thorough investigation into engine performance features and the scavenging process. In particular it provides a detailed examination of how changes in EVO and EVC timing impact the scavenging process and ultimately engine performance. These results are summarized, and based on these results, optimal EVO and EVC settings are suggested for balancing the scavenging process, and also the engine performance and NOx emissions.
