摘要： A four-stroke engine with an isolation chamber. The isolation chamber has a pressure-sensitive wall attached to or slidably mounted within the isolation chamber. The pressure-sensitive wall is substantially impervious to air, oil, and fuel. When the piston moves away from the crankcase, a vacuum is created in the crankcase. This draws the pressure-sensitive wall toward the crankcase, fluidwise, and movement of the pressure sensitive wall pulls air into the intake side of the isolation chamber through a one-way valve or time induction mechanism. When the piston moves toward the crankcase, increased pressure within the crankcase forces the pressure-sensitive wall away, fluidwise, from the crankcase and pushes air from the isolation chamber into the combustion chamber. The pressure-sensitive wall prevents oil from flowing from the crankcase. Power in a four-stroke engine is increased up to as much as 40%, without the necessity to employ superchargers or turbochargers.
摘要翻译：具有隔离室的四冲程发动机。隔离室具有附接到或可滑动地安装在隔离室内的压敏壁。压力敏感壁基本上不透空气，油和燃料。当活塞远离曲轴箱时，在曲轴箱中产生真空。这样使压敏壁向流体方向流向曲轴箱，并且压力敏感壁的运动通过单向阀或时间感应机构将空气吸入隔离室的进气侧。当活塞朝向曲轴箱移动时，曲轴箱内的增加的压力迫使压力传感器从流体方向从曲轴箱移开，并将空气从隔离室推入燃烧室。压敏面板防止油从曲轴箱流出。四冲程发动机的功率增加到高达40％，而不需要使用增压器或涡轮增压器。

摘要： This invention concerns a two-stroke cycle engine, more specially it concerns a two-stroke cycle engine using a preceding air-layer for scavenging. It has a scavenger passage connected to a branching scavenger passage opened to said scavenging port. The engine has a connecting passage to link the air passage and the fuel passages so that negative pressure in the air passage forces the fuel-air mixture in the fuel passage into said air passage. Further, the engine according to this invention has a removable guide with a surface forming a curved smooth channel which is attachable to the scavenger passage in the crankcase from the mounting surface, and forms a portion of said scavenger passage with the curved channel. The blowup angle of the scavenger passage varies along the circumferential direction of the cylinder. The crankcase is configured in such a way that the front and rear portions, which are separated by a block, and a scavenger passage is provided inside both said front and rear portions of said crankcase, and the cylinder. The air cleaner has two air passages running from it in parallel, the first one is connected to said air passage, and the second one is connected to the air inlet of the carburetor to provide air for the fuel passage, and a choke valve on the air cleaner is provided to open and close both of the first and second air passages.

摘要： A connector between a carburetor and a cylinder connection of an internal combustion engine of an implement is provided. The flow channel formed in the connector is provided with raised portions over the inner periphery of the channel. To avoid fluctuations in the speed of the engine as a function of changes in position of the implement, the raised portions are embodied as wall portions that are oriented approximately transverse to the center line of the channel. The wall portions provide a flow cross-section for the channel that varies in a step-shape or terrace-shaped manner.

摘要： The invention relates to the combination of an air filter and a membrane carburetor (1). The membrane carburetor (1) has an intake channel section (3) configured in the carburetor housing (2) into which the fuel-conducting channels (4, 4′) open which are fed from a control chamber (5) of the carburetor housing (2). The control chamber (5) is separated by a control membrane (6) from the compensation chamber (7). A compensation channel (11) leads from the compensation chamber (7) into a flow space (9). A connecting piece (8) is led into the flow space (9) as a connection of the intake channel section (3) of the membrane carburetor (1) with the flow space (9). The compensation channel (11) and the connecting piece (8) open into the housing (21) on the clean air side (23). The housing (21) forms the flow space (9). The compensation channel (11) is guided into the housing (21) via a segment (10) in the connecting piece (8) to provide a simpler assembly and constructive configuration of the compensation connection. The opening (15) of the compensation channel (11) defines a first plane (17). The opening (16) of the connecting piece (8) defines a second plane (18). The planes (17, 18) are separated from each other and these planes preferably intersect.

摘要： A motorcycle and specifically an improved compact air inlet device and filter assembly for a motorcycle. The air inlet device is provided with a relatively large volume but an irregular shape to permit positioning in the area over the engine and beneath the fuel tank. By utilizing a horseshoe-shaped filter element, however, a large filter surface area may be achieved so as to reduce service intervals and to ensure that the engine will operate without flow restriction for a long period of time even if the filter element is not serviced.
