Abstract: 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 blow-up 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.

Abstract: Hall ICs constituting a redundant throttle valve position sensor are used to measure a rotational angle value indicative of a position of a throttle valve and a temperature value indicative of an ambient temperature change, which is continuously monitored, around the Hall ICs. The rotational angle value measured by the Hall ICs is appropriately adjusted based on the measure temperature value of its own, and a throttle valve position is determined in an externally connected ECU based on the adjusted angle value. In addition, the temperature value measured by one Hall IC is inputted to the ECU. In the ECU, various control values, such as a resistance value of an electric motor, can be appropriately adjusted based on the measured temperature value.

Abstract: A rotating shaft and a drive shaft are used in an air intake apparatus for an internal combustion engine. At one end portion of the rotating shaft and the drive shaft a sphere portion and a projection portion are formed, and another end portion of the rotating shaft and the drive shaft a cup portion and a faucet portion are formed. The sphere portion is inserted to the cup portion and further the projection portion is engaged with the faucet portion, thereby a universal joint is formed. Since a connection structure between the rotating shaft and the drive shaft is constituted with few component elements, a cost reduction in the air intake apparatus for the internal combustion engine can be improved.

Abstract: A piston is formed with one or more recesses or depressions on its underside as it is cast, molded or forged. The recesses are located adjacent the outer cylindrical wall of the piston head so that when a groove such as an oil ring groove is subsequently machined into the outer wall, the groove intersects and cuts into each recess. In this manner, oil drain ports are formed in the oil ring groove without the need for additional boring or cutting operations.
