摘要： In a two-stroke engine (1) according to the present invention, a piston (6) has a communication passage (28) opened to a crank chamber (10). An air intake port (30) is provided on an inner surface (2a) for causing air to flow into the communication passage (28). After a scavenging port (22) is closed by an outer surface (6a) of the piston (6) moving from the bottom dead center to the top dead center, the communication passage (28) is opened in the outer surface (6a) of the piston so as to communicate with the air intake port (30) and the scavenging port (22).

摘要： There is provided an air cleaner that is capable of suppressing or reducing malfunctions and problems caused by mixed fuel that back flows from a carburetor, thereby prolonging filter life, reducing filter maintenance frequency, etc. The air cleaner comprises: a fuel accumulation part formed near, and so as to surround, a cleaner outlet provided in a cleaner bottom wall located towards the carburetor, the fuel accumulation part being adapted to accumulate mixed fuel that back flows from the carburetor; a back flow guide member that guides the mixed fuel that back flows into the air cleaner via the cleaner outlet not towards a filter but towards the fuel accumulation part; and a plurality of return flow paths, each of which has one end that is in communication with the fuel accumulation part and another end that is in communication with the cleaner outlet so as to return the mixed fuel that accumulates in the fuel accumulation part back towards the carburetor utilizing intake negative pressure, wherein the plurality of return flow paths are provided in a radial fashion about the cleaner outlet and each comprise a flow path forming plate part whose upper end surface comprises a sloped surface that slopes downward towards the cleaner outlet.
摘要翻译：提供一种能够抑制或减少由化油器返回流动的混合燃料引起的故障和问题，从而延长过滤器寿命，降低过滤器维护频率等的空气滤清器。空气净化器包括：靠近形成的燃料积聚部分并且围绕设置在朝向化油器的清洁器底壁中的清洁器出口，所述燃料积聚部适于累积从所述化油器回流的混合燃料; 后向流引导构件，其将经由清洁器出口返回的混合燃料引导到空气净化器中，而不是朝向过滤器而是朝向燃料积聚部分; 以及多个回流路径，每个返回流路具有与燃料积聚部分连通的一端和与清洁器出口连通的另一端，以使积聚在燃料积聚部分中的混合燃料返回到所述化油器利用进气负压，其中所述多个回流路径围绕所述清洁器出口以径向方式设置，并且每个包括流路形成板部分，其上端表面包括朝向所述清洁器出口向下倾斜的倾斜表面。
