WebLoop scavenging was important for large MAN and Sulzer two-stroke engines (with stroke to bore ratios of about 2) until the 1980s [2265][3997]. With loop scavenging, the exhaust ports open first and allow some … Web1 jan. 1990 · Abstract. The scavenging process is the most important factor controlling the efficiency and performance characteristics of a two-stroke-cycle engine. This article reviews and assesses experimental and theoretical methods, which have been applied during the past three decades, to evaluate the success of the scavenging process.
WebTwo-stroke engines are preferred when mechanical simplicity, lightweight, and high power-to-weight ratio are design priorities. They are lubricated by the traditional method of mixing oil into the fuel, they can be worked within any orientation as they do not have a reservoir dependent on gravity.
