摘要： An exhaust port and an intake port are formed across a crankshaft with a flywheel provided at one end when viewed in a direction of an axis of a cylinder at a two-stroke engine. A pair of scavenging ports is then formed between the exhaust port and the intake port. Scavenging path covers are fitted to a cylinder block of the two-stroke engine and constitute part of scavenging paths that connect the scavenging ports and a crank chamber. The scavenging path cover close to the flywheel is positioned between an axis of the crankshaft and an exhaust path connected to the exhaust port or an intake path connected to the intake port.

摘要翻译： 当在二冲程发动机的圆柱体的轴线方向上观察时，排气口和进气口横跨曲轴形成有飞轮，该飞轮设置在一端。 然后在排气口和进气口之间形成一对扫气口。 清扫路径盖安装在二冲程发动机的气缸体上，并构成连接清扫口和曲柄室的扫气路径的一部分。 靠近飞轮的清扫路径盖位于曲轴的轴线和连接到排气口的排气通道或连接到进气口的进气路径之间。
