MIXTURE-LUBRICATED FOUR-STROKE ENGINE

A mixture-lubricated four-stroke engine has a cylinder (2) and a piston (3). On the piston (3), at least one piston ring (4) is arranged. Between valve drive chamber (16) and crankcase interior (15),at least one first channel (17) is arranged. The first opening (18) of the first channel (17) lies in...

Beschreibung
Zusammenfassung:	A mixture-lubricated four-stroke engine has a cylinder (2) and a piston (3). On the piston (3), at least one piston ring (4) is arranged. Between valve drive chamber (16) and crankcase interior (15),at least one first channel (17) is arranged. The first opening (18) of the first channel (17) lies in the bottom dead center position of the piston (3) below each piston ring (4). At the first opening(18), the first channel (17) defines a first middle flow direction (25) for mixture flowing into the crankcase interior (15). The first middle flow direction (25) extends inclined towards the combustion chamber (5) and in a viewing direction perpendicular to the cylinder longitudinal plane (33) intersects the longitudinal center axis (21) above the first opening (18) of the first channel (17). 一种混合物润滑的四冲程发动机具有气缸（2）和活塞（3）。在活塞（3）上布置有至少一个活塞圈（4）。在阀驱动室（16）与曲柄壳体内部空间（15）之间布置有至少一个第一通道（17）。第一通道（17）的第一开口（18）在活塞（3）的下死点位置中位于每个活塞圈（4）的下方。第一通道（17）在第一开口（18）上预设针对流入曲柄壳体内部空间（15）的混合物的第一中间流动方向（25）。第一中间流动方向（25）朝燃烧室（5）倾斜地延伸，并且沿垂直于气缸纵向平面（33）
