摘要： A piston and cylinder for two-cycle engines wherein the fuel-air mixture is precompressed in the crankcase and flows to the combustion chamber through transfer passages formed in the cylinder wall and under the control of the piston movement. The piston skirt is formed with windows or openings adjacent the end faces of the piston pin, the latter being mounted in piston pin bosses carried by bearing brackets depending from the piston head and, when the piston is at its lower dead center, the windows or openings register with the inlet openings of the transfer passages so that the precompressed fuel-air mixture then flows through the interior of the piston, the openings in the piston skirt and the transfer passages and into the combustion chamber itself which contains a depression volume. The windows or openings in the piston skirt have approximately the same size as the inlet openings of the transfer passages which register with the windows when the piston is at its lower dead center and the piston pin bosses have an aerodynamically favorable shape and are joined to the lower frame portions defining the windows and spaced apart as closely as possible whereas the depression volume of the combustion chamber is accommodated to a substantial extent in the piston head.
摘要翻译：一种用于双循环发动机的活塞和气缸，其中燃料 - 空气混合物在曲轴箱中被预压缩并且通过形成在气缸壁中并且在活塞运动的控制下的传送通道流动到燃烧室。活塞裙部形成有与活塞销的端面相邻的窗口或开口，后者安装在活塞销凸台上，活塞销凸起由活塞头悬挂，并且当活塞处于其下死点时，窗口或开口与传送通道的入口开口对准，使得预压缩的燃料 - 空气混合物然后流过活塞的内部，活塞裙部中的开口和输送通道并进入包含凹陷体积的燃烧室本身。活塞裙部中的窗口或开口具有与当活塞处于其下死点时与窗口对准的传送通道的入口大致大致相同的尺寸，并且活塞销凸起具有空气动力学良好的形状并且连接到下部框架部分限定窗口并且尽可能地间隔开，而燃烧室的按压体积在活塞头中被大量地容纳。

摘要： To enable prescribed functional values of pressure plate units of motor vehicle friction clutches to be observed with smaller tolerances than hitherto, it is proposed that a housing-spring component initially be pre-assembled from clutch housing (1) and diaphragm spring (7) and that this component be measured together with a master pressing plate. Geometry (diameter 25 and axial height 27) which is optimum for minimum tolerances of a contact bevel 15 is calculated by means of the measured result, and a pressing plate (13) with this bevel geometry is produced. The measured spring-housing component is finally assembled together with this specially produced pressing palte 913).
