Two-stroke internal combustion engine having a crankcase scavenging system

摘要

In the crankcase scavenging system of a two-stroke internal combustion engine, there is provided a transfer port (9) which is connected to a transfer slot (10) via a bend (12) in this port and into which leads a port (11) for a scavenging receiver. To prevent deterioration of the flow conditions in the transfer port (9) as a result of the port (11) for the scavenging receiver opening into this transfer port, the port (11) for the scavenging receiver is connected to the transfer port (9) on the inner side of the port bend (9) immediately before the transfer slot (10). <IMAGE>
