摘要： A two-stroke cycle internal combustion engine (10) has a one-piece cylinder housing (14) which is vertically aligned with a crank housing (16) and a valve housing (12) mounted at a top section of the cylinder housing. The valve housing (12), cylinder housing (14), and crank housing (16) are generally formed in a substantially symmetrical manner about a vertical axis line (20). The valve housing (14) contains a valve control mechanism (54) which aids in the reversible vertical placement of a valve member (34) having an extended length value stem (38) and a valve head (36). A controlled air insertion mechanism (92) provides for high pressure air to be inserted into a combustion chamber (42) to thoroughly expel spent gases through exhaust port 46 and there is further provided a recess (102) for cooperation with a relief opening (104) to relieve gas pressures built up.

摘要： The present invention pertains to the field of engine construction and relates to internal combustion engines with scavenging and more precisely to two-stroke engines. At the beginning of the exhaust stroke, the exhaust gases are expelled from the engine cylinder through inlet and outlet ports, inlet and outlet passages and slide valves into an exhaust pipe. Scavenging ports are then uncovered by an upper edge of the piston and used to feed a fresh charge into the cylinder from the crank chamber while the cylinder cavity is scavenged. After expelling the exhaust gases from the cylinder cavity, the slide valves rotate to interrupt the communication between the cylinder cavity and exhaust manifold. Upon further rotation of the slide valves, the cylinder cavity is connected with the inlet pipe through the same gas-distribution organs used for the exhaust gas outlet, i.e. the inlet and outlet ports, the inlet and outlet passages and the slide valves. A fresh charge can thus be fed into the cylinder through all the ports it comprises, whereby the cylinder of a two-strike engine may be charged without any losses in the charges and with the appropriate preliminary compression ratio.
摘要翻译：本发明涉及发动机结构领域，涉及具有清扫性，更准确地涉及二冲程发动机的内燃机。在排气行程开始时，废气通过入口和出口，入口和出口通道和滑阀从发动机气缸排出到排气管中。清扫口然后被活塞的上边缘覆盖，并且用于在气缸腔被清除的同时从曲柄室向气缸供给新的电荷。在从气缸腔排出废气之后，滑阀旋转以中断气缸腔和排气歧管之间的连通。在滑动阀进一步旋转时，气缸腔通过与废气出口相同的气体分配器，即入口和出口，入口和出口通道以及滑阀与入口管连接。因此，可以通过其包括的所有端口将新鲜的电荷进料到汽缸中，由此双冲程发动机的气缸可以在充电中没有任何损失并且具有适当的预压缩比来充电。

摘要： A motorcycle powered by a two cycle internal combustion engine having an improved induction system that has a vertically extending intake pipe so as to permit a wide latitude of leaning of the motorcycle without interference from the induction system. The induction system serves the crankcase of the engine through a rotary plate type valve that has a helical connection to the engine output shaft so that the timing of the opening and closing of the intake port can be adjusted. A servo motor adjusts the helical connection under the CPU so that the timing change mechanism need not be powered directly by the engine.

摘要： An opposed piston two cycle internal combustion engine. The movement of the opposed pistons is transmitted to two cranks, the two cranks are interlocked together by gears. The gears maintain synchronized movement of the cranks and further act as an air pump to force air intothe intake manifold 20. A fuel charge is admitted into the intake tube 19 and is controlled by the rotary valve 17 for admission into a pre-compression crankcase 3. The rotary valve allows for further communication between the precompression crankcase 3 and injection crankcase 2 via passage 22. Air is introduced into the combustion space 10 via inlet ports 14. A fuel/air mixture is further controllably introduced via a fuel injection port 13 in the injection piston 4. The exhaust ports 15 are opened prior the timing of the intake ports 14 and close prior the closing of the intake ports 14 for superior scavenging.

摘要： An improved two cycle engine is disclosed which includes a subchamber which is in communication with the exhaust port with a cylindrical valve rotatably disposed therebetween. A reed valve unit is turnably supported in the inlet port to open and close the latter. The cylindrical valve is operatively connected to the reed valve unit by way of a linkage mechanism. Either of the cylindrical valve and the reed valve unit is actuated by a servomotor and the other one is actuated by the linkage mechanism. The servomotor is controlled with the aid of a control circuit so as to allow the engine to be operated at a predetermined number of revolutions.
