摘要： There is disclosed a four-cycle engine in which a crankshaft and a cam shaft are disposed generally parallel to each other, and an intake port and an exhaust port are formed in a cylinder head. The intake port and the exhaust port are arranged in such a manner that a line passing through the centers of the intake port and the exhaust port is non-parallel to the axis of the crankshaft. With this arrangement, an intake passage and an exhaust passage can be greatly shortened, and therefore intake efficiency as well as exhaust efficiency can be enhanced, thereby enhancing the performance of the engine. In an air-cooled engine, the overheating of the engine is greatly restrained.

摘要： A two-cycle combustion engine having a two-staged piston, is simple in structure and inexpensive and addresses a undesirable blow-off phenomenon of the air-fuel mixture. The two-cycle combustion engine includes a cylinder block having a two-staged cylinder bore with a reduced diameter bore portion and a large diameter bore portion, and a two-staged piston having a reduced diameter piston portion and a large diameter piston portion. An annular auxiliary chamber is defined between the two-staged cylinder bore and the reduced diameter piston portion. The two-cycle combustion engine also includes an air-fuel mixture passage for introducing the air-fuel mixture into a crank member, an air passage for introducing air into the auxiliary chamber, a scavenge passage for supplying the air-fuel mixture within the crank chamber into a combustion chamber, and injection passages and for injecting the air within the auxiliary chamber into the combustion chamber to counter a press-out issue.

摘要： In a conventional impact generator, a great shock is generated when a weight collides with a rotary member, and a rotary shaft of the rotary member and a bearing supporting the rotary shaft receive the great shock. Therefore, it is necessary to employ a bearing having a great load capacity. Furthermore, great vibrations and noises are also generated in the impact generator. A rotary member (10) is rotatably supported by rotary shafts (11) and (12). A weight (30) is movably held by the rotary member (10). A shock absorber (40) for absorbing, by elastic force, a shock generated between the weight (30) and the rotary member (10) is provided between the weight (30) and the rotary member (10).
