摘要： A barrier ring for a cylinder assembly for an opposed-piston engine fits into a groove fashioned into a portion of the cylinder liner that is adjacent to the top dead center location of the end surfaces of the pistons, in a volume of the cylinder liner that defines the combustion chamber. The barrier ring and groove are part of a barrier assembly that prevents heat generated during combustion from reaching the outer wall of the cylinder assembly, reducing the need for conventional cooling systems and increasing the amount of heat retained in the combustion chamber. The barrier assembly allows for increased engine efficiency because of the combustion heat retained in the combustion chamber, as well as a reduction in the overall size of the engine because of the reduction in engine cooling needed.

摘要： To balance a "low-temperature scavenging effect" and a "high-temperature scavenging effect." A scavenging system (100) applicable to a leading-air type two-stroke air-cooled engine has a low-temperature scavenging passage (102) and a high-temperature scavenging passage (104). The low-temperature scavenging passage (102) has first and second passages (106, 108) and includes scavenging ports (106a, 108a) at upper end parts thereof. The high-temperature scavenging passage (104) has first and second passages (110, 112) and includes scavenging ports ( 110a, 112a) at upper end parts thereof. An air is filled through a piston groove into the passages (106, 108, 110, 112). The low-temperature scavenging passage (102) has a relatively small capacity. The high-temperature scavenging passage (104) has a relatively large capacity.

摘要： The invention relates to a two-cycle combustion engine, comprising at least one cylinder (1) accommodating a piston (2) and provided with a cylinder head, comprising a crankcase (10) which is in fluid connection with the cylinder (1) by way of transfer ports (12 to 16) which are disposed symmetrically opposite from each other with respect to a diameter plane (5) of the cylinder (1) that is determined by the axis of an outlet port (4), and comprising two injection nozzles (6, 7) for fuel disposed symmetrically to said diameter plane (5), the nozzle axes (8) of which intersect each other above the piston crown (3) in the diameter plane (5) in the bottom dead center position of the piston (2). In order to create advantageous scavenging conditions, it is proposed that the nozzle axes (8) intersect each other on the side of the cylinder axis facing away from the outlet port (4) and extend at least approximately in the outflow direction (17) of the transfer ports (12, 13) provided on the opposite side of the diameter plane (5), and that the piston (2) comprises a casing opening (21) for injection fuel into the crankcase (10) on at least one peripheral side facing the injection nozzles (6, 7).

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.
