摘要： A cycle changeable engine includes first intake valves (1) for a four-cycle operation which are disposed in intake ports (11) formed in a cylinder head (3), exhaust valves (2) disposed in exhaust ports (22), second intake valves (5) for a two-cycle operation, disposed in intake ports (9) formed at the lower part of a cylinder (6), and an electromagnetic valve driving device (10) for opening and closing each of the valves by electromagnetic force. The engine includes also a controller (15) which actuates either the first or second intake valves for opening and closing with the others being kept closed in response to a detection signal from detection means for detecting the number of revolutions or load of the engine, and changes the operational condition of the engine to the two-cycle or four-cycle operation. In this manner the engine is operated in the two-cycle operation at a low speed revolution of the engine to improve an output torque and is operated in the four-cycle operation at a high speed revolution of the engine to reduce fuel consumption, to improve mean effective pressure and volume efficiency and to reduce noise.

摘要： A fuel system for internal combustion, two-cycle or four-cycle engines in which hot combustion gases are introduced under pressure to the cylinder to be next fired along with raw fuel injection. The purpose is to preheat and atomize the fuel to obtain more efficient and more complete combustion. The respective cylinders are connected by cross-passages whereby hot gases from the combustion in one cylinder will be transferred along with heated vaporized fuel to an adjacent cylinder at proper timing with an electrically triggered fuel injection valve or device.

摘要： The manufacturing process for aluminium alloy die-cast cylinders is started with the injection of the molten aluminium separately in the respective dies for the upper cylinder part (10) and the lower part (11). Thereafter, after the injection operation is completed and before joining (10) and (11), both are turned by the mould stripping line 14.
To join (10) and (11), the upper portion of the cylinder (10) is heated by any process to achieve expansion of (10) and thereafter, by mere pressure, (10) and (11) are coupled thus forming a single unit on cooling down.

摘要： A base structure of a motor saw forms fuel and oil tanks (16,17) and a crankcase bottom in one piece. This piece is injection moulded in plastics with closed tank cavities obtained by means of cores in the mould which are made of a metal having a melting temperature lower than the softening temperature of the plastic material. After moulding the cores are melted by heat treatment and the metal runs out through filling holes (18,19) of the tanks. Armouring pieces are moulded in the plastics to reinforce the attachments of crankshaft bearings and the sword.

摘要： An exhaust control system for 2-cycle engines has a main exhaust passage, auxiliary exhaust passages arranged in parallel with the main exhaust passage, and an expansion chamber communicatable with the main exhaust passage. During low-speed operation of the engine, the auxiliary exhaust passages are shut-off while the expansion chamber is connected to the mainexhaust passage, whereas, during high-speed operation of the engine, the auxiliary exhaust passages are opened and the expansion chamber is closed.
