摘要： An internal combustion engine comprises a combustion chamber and a piston movable relative to the combustion chamber between top dead center and bottom dead center positions. A fuel transfer passage introduces fuel-air mixture into the combustion chamber in response to piston movement. An auxiliary chamber is also provided which is communicable with the combustion chamber in response to piston movement shortly after the ignition of a fuel-air mixture, such that high pressure ignition gases enter the auxiliary chamber. The high pressure ignition gases thereafter flow back into the combustion chamber in response to piston movement before communication is established between the combustion chamber and the fuel transfer passage. The incoming flow of high pressure ignition gases serves to influence the normal scavenging streams. The auxiliary chamber can also function as an auxiliary transfer passage in response to piston movement to supplement the fuel transfer passage in supplying a new fuel-air mixture charge to the combustion chamber. In one embodiment, an air transfer passage is provided for introducing fresh air into low pressure regions in the cylinder to lend overall stability to the scavenging process.

摘要： An internal combustion engine includes at least one piston (1) which is reciprocally received in a cylinder (2) which is coupled to a rotary output shaft (17) by a coupling (5, 22) which converts reciprocal movement of the piston into rotary movement of the output shaft. The engine is so arranged that, in use, the fuel/air mixture in the or each cylinder ignites at a predetermined ignition time in the operation cycle of the engine. The coupling is so arranged or programmed that on its compression stroke the speed of the piston deceases abruptly substantially at the ignition time and that the speed of the piston subsequently increases prior to reaching the top dead center position.

摘要： A high performance two-stroke internal combustion engine comprises at least one disc inlet valve driven from a shaft via bevel gears. The shaft is driven from a pinion secured to the engine crank-shaft via a variable drive. The variable drive includes a spring which biases a cross pin to one end of a spiral slot in the shaft to maintain pinion at a position relative to the shaft which provides maximum inlet valve advance during starting. As engine revs increase the pinion progressively leads the shaft thereby retarding inlet valve timing. When the valve timing is fully retarded a bobbin of the drive is latched by a magnet to hold the valve timing fully retarded until engine revs fall.
