摘要： A two-stroke internal combustion engine (10) including a cylinder (12); and a piston (14) movably mounted in the cylinder (12). The cylinder (12) includes an exhaust port (34) and transfer ports (36). The transfer ports (36) include a first pair of the transfer ports (44, 48) disposed closer to the exhaust port (34)than a second pair of the transfer ports (46, 50) which are disposed further away from the exhaust port (34). The first pair of transfer ports (44, 48) are angled relative to each other at a first angle of about 70° to about 85 ° and the second pair of transfer ports (46, 50) are angled relative to each other at a second angle of about 120° to about 150°. Directional discharge of scavenged air out of the transfer ports (36) establishes a flow path for the scavenged air to minimize losses of the fresh unburned fuel into the exhaust port (34).

摘要： In a gas internal combustion-type nailing machine, a cylindrical sleeve (33) is fixed between a movable housing (31) and a fan (7). An annular space part (S) is formed between the movable housing (31) and the sleeve (33). Communication holes (33a, 33b) communicating with the annular space part (S) are formed in the sleeve (33) at the parts upper and lower than the fan (7), respectively. A mixed gas discharged by the fan (7) flows through the lower communication hole (33b), the annular space part (S) and the upper communication hole (33a) and returns to a combustion chamber (3).

摘要： A powered apparatus constitutes a utilitarian device removably mounted on an internal combustion engine. That engine has a housing, a vertical crankshaft, and an engine coupling connected to the upper end of the crankshaft. The utilitarian device includes a body and a drive connector that is removably coupled to the crankshaft to receive rotational force from the internal combustion engine. The weight of the utilitarian device is carried by a support bearing which is fixedly connected to either the body or the engine coupling and releasably engages the other of the body and the engine coupling.

摘要： The invention relates to a crankcase (1) for an air-cooled combustion engine for a handheld working machine, for example a brushcutter or a trimmer, comprising a crankcase chamber (20), a flywheel side (2) with a fan scroll (4) and a fan wheel (3) arranged in the fan scroll, a clutch side (11) opposite the flywheel side and a number of crankcase walls between the fan wheel side and the clutch side. Through a crankcase wall on at least one side between the fan wheel side and the clutch side, one or more cooling ducts (32) extend between one or more inlet openings (35) for cooling air in the fan scroll and one or more outlet openings (50) for the cooling air, exiting into the clutch housing (12), for cooling of the wall on said at least one side between the fan wheel side and the clutch side.

摘要： A four-stroke engine (10) employs engine vibration for lubricating engine components. The engine vibration induces a ripple in a surface portion of the oil in an oil reservoir (38), which is located within a crankcase (26) of the engine (10). The oil ripple causes misting of the oil, which lubricates exposed engine components. Providing a crankcase (26) wall thickness of about 1.5 mm or less can increase the engine vibration. Alternatively, a clearance area (46) located within the crankcase (26) can be decreased to facilitate contact of the oil surface ripple with a counterweight, thereby splashing the oil onto exposed engine components. Vibration of the engine (10) can be further increased by coupling a vibration plate or spring to a portion of the crankcase (26).

摘要： This invention relates to a flexible intake system for a crankcase scavenged two-stroke internal combustion engine (10) having an additional air supply to its transfer ducts. The intake system comprises a flexible intake duct (22) connecting a fuel supply unit (21) e.g. a carburetor with an engine cylinder (11) and at least one flexible air duct (40) connecting a valve housing (42) for additional air with the engine cylinder. The end portion of the flexible intake duct (22) and at least one air duct (40) is secured to the cylinder by means of a baffle (23) made of a stiffer material than the ducts (22, 40) themselves.

摘要： An engine-driven work machine (10) having a target engine speed selection unit (65) and a control unit (89). The target engine speed selection unit (65) selects and specifies an arbitrary target engine speed from among a plurality of target engine speeds that is set in stepwise fashion. The control unit (89) electrically controls the opening and closing of a throttle valve (92) so that the actual engine speed (14) conforms to the specified target engine speed.

摘要： A two-cycle engine (10) includes a crankshaft (13) that has shafts (17, 18) on both sides and a crankcase (12) that pivotally supports the shafts (17, 18) of the crankshaft (13) through bearings (21, 26). A collar (29) is circumferentially provided on an outer ring of one of the bearings (26) that supports one of the shafts (18) on a side at which a low load is applied. The crankcase (12) is provided with an inserting portion (24) into which the one of the bearings (26) is inserted. The inserting portion (24) penetrates the crankcase (12) while keeping a constant diameter. An engaging portion (27) with which the collar (29) is engaged from an inner side is provided in an inner portion of the inserting portion (24).
