摘要： 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 (109d) connected to a branching scavenger passage (1 09d) opened to said scavenging port (9a). The engine has a connecting passage to link the air passage (10b) and the fuel passage (15) so that negative pressure in the air passage (10b) forces the fuel-air mixture in the fuel passage (15) into said air passage (10b). Further, the engine according to this invention has a removable guide (501) with a surface forming a curved smooth channel which is attachable to the scavenger passage (109d) in the crankcase (5) from the mounting surface, and forms a portion of said scavenger passage (109d) with the curved channel. The blow-up angle of the scavenger passage (109d) varies along the circumferential direction of the cylinder (2). The crankcase (5) is configured in such a way that the front and rear portions, which are separated by a block, and a scavenger passage (109d) is provided inside both said front and rear portions of said crankcase (5), and the cylinder (2). The air cleaner (1001) has two air passages (1061, 1071) running from it in parallel, the first one (1061) is connected to said air passage (10b), and the second one (1071) is connected to the air inlet of the carburetor (12) to provide air for the fuel passage (15), and a choke valve (1201) on the air cleaner (1001) is provided to open and close both of the first and second air passages (1061, 1071).

摘要： A crankcase scavenged internal combustion engine of two-stroke type (1) having at least one cylinder (15) and at least one air passage arranged between an air inlet (2) and the upper part of a number of scavenging ducts (3, 3') with exhaust orientated scavenging ports (9, 9') located close to the exhaust port (19) of the cylinder. At least one intake orientated scavenging port (14, 14') is located close to the inlet port (33) of the cylinder and is fed by at least one scavenging duct (5, 5'), and the air passage and the scavenging ducts are so arranged that the scavenging ducts (3, 3') can be supplied with and hold so much air that they during the following scavenging process will scavenge essentially nothing but air. The air passage is arranged from an air inlet (2) provided with a restriction valve (4) controlled by at least one engine parameter, e.g. the carburettor throttle control, and the intake orientated scavenging port/s (14, 14') is/are so arranged that it/they begin/s to scavenge the air/fuel-mixture (2) later than the scavenging ports (9, 9') begin to scavenge air.

摘要： An SAS two-cycle engine (10) has a cylinder block (12) that has a bore (14) with at least one scavenging port (32) and at least one fresh air port (62, 64) therein. The bore (14) extends to a crankcase (20). A piston (50) of the engine (10) is located within the bore (14) and separates a combustion chamber (52) of the bore (14) from the crank area (22) and is movable between a first position, in closest proximity to the crank area (22), and a second position. The air port (62, 64) and the piston (50) are configured such that air may flow from the air port (62, 64) into the combustion chamber (52) of the cylinder when the piston (50) is at the first position. In one example, the scavenging port (32) and the air port (62, 64) have edges that are selectively revealed upon movement of the piston (50). The air port (62, 64) includes an upper edge (66, 68), which may be contoured such that only a portion of the upper edge (66, 68) is exposed when the piston (50) is at the first position.

摘要： There are provided scavenging passages (11) on the cylinder side and the crankcase side (10) as the passages to supply scavenging gas into the cylinder (3) in a loop scavenging type two-cycle engine (1). The passage (11) on the cylinder side comprises a passage inside the cylinder sidewall having substantially the same diameter as that of the opening area of the scavenging charge port, while the passage (10) on the crankcase side comprises a space (12) between the inner peripheral surface at the top end of the crankcase and the outer peripheral surface of the piston, and a connection means (13) provided between the top end of the space and the lower end of the scavenger passage of the cylinder. As the fuel mixture in the crank chamber (5) flows into the scavenging passage (11) on the cylinder side through the narrow space of the passage (10) on the crankcase side and the connection means, the rapid inflow of the fuel mixture into the cylinder (3) is restrained and the supply of the fuel mixture is sustained constantly high until the latter half of the scavenging time. This enables an optimum supply of fuel mixture, and radically decreases the amount of unburned gas in the fuel mixture that is emitted with the exhaust gas.

摘要： An internal combustion engine (1) has a positive displacement supercharger (8) which can be used with particular advantage in an underpumping two stroke engine which is in the form of a valved diaphragm which reciprocates in a housing to deliver positive pulses of air. The internal combustion engine (1) also has an oiling system which comprises injecting oil between the piston (4) and cylinder walls (2) at discrete time intervals and any excess oil is removed through galleries in the piston (4), con rod (5) and main shaft (6) preferably by a vacuum exerted on the galleries. Various other innovative features include a two part exhaust valve (9), generation of the vacuum by a positive displacement supercharger, a two-part cylinder head (3), use of inserts on moving parts to increase the efficiency of an underpumping engine and a specially constructed flywheel (11).
