Two stroke scavenging
WebThe two stroke engines have poor scavenging which causes the unburnt charge or incompletely combusted charge to escape through the exhaust. Thus the exhaust of 2 stroke engine contains more pollutants. Hence the use of a two stroke engine is rare in comparison with 4 stroke engines. Webcylinder [3,15–17]. Scavenging system optimization is an effective method to improve the engine performance. For conventional two-stroke engines, the scavenging efficiency was often employed as the optimization objective. However, most two-stroke scavenging systems are “scavenging

Schnuerle scavenging (sometimes called "loop scavenging" or "reverse scavenging") is a design used by most modern valveless two-stroke engines. The key difference compared to crossflow scavenging is that the transfer ports are located either side of the exhaust port and aimed at the opposite cylinder wall. [3] See more Scavenging is the process of replacing the exhaust gas in a cylinder of an internal combustion engine with the fresh air/fuel mixture (or fresh air, in the case of direct-injection engines) for the next cycle. If scavenging is … See more Crossflow Scavenging Crossflow cylinder heads are used by most modern 2-stroke engines, whereby the intake ports are located on one side of the combustion chamber and the exhaust ports are on the other side.
