    摘要： A positioning pin is knocked onto a crankshaft of an engine and a key way is formed in a boss of a first flywheel. When an outer rotor type generator is connected with the engine, the boss of the first flywheel is fitted over the crankshaft so as to adjust the positioning pin to the key way. When an inner rotor type generator is connected with the engine, a rotor shaft on which a rotor of a generator is mounted is fitted to a second flywheel so as to adjust the positioning pin to a key way formed in the second flywheel. The ignition angle of the engine is determined by fitting the positioning pin to the key way.

    摘要： A two-cycle engine is provided, especially in a manually-guided implement such as a power chain saw, a brush cutter, a trimmer or the like, and has a cylinder in which is formed a combustion chamber that is delimited by a reciprocating piston that, via a connecting rod, drives a crankshaft that is rotatably mounted in a crankcase. In prescribed positions of the piston, the combustion chamber is connected with the crankcase via at least two transfer channels. At least one air channel is provided that opens out at an air channel window at the cylinder in the region of the piston, and that, in prescribed positions of the piston, is connected with at least two transfer channels via a piston window formed in the piston. To achieve a good scavenging of the combustion chamber, and hence low exhaust gas values of the engine, structural features are provided on the piston window for the defined distribution of air to the transfer channels.

    摘要： A crankcase scavenged internal combustion engine includes a cylinder and a piston reciprocating along the cylinder wall. At least one auxiliary duct is arranged with an auxiliary port in the cylinder wall. An inlet is divided into: a fuel inlet leading to a fuel port and an air inlet leading to an air port. The auxiliary port, fuel port and air port can be opened and closed by the piston. The piston also comprises a transfer space, which mouth edges are limited by the piston periphery, and which, in at least one piston position, creates a connection between the fuel port and the auxiliary duct's port, so that fuel can be supplied to the auxiliary duct via the auxiliary port, and then, after the port later on has been opened by the piston, can flow into the combustion chamber.

    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.
