    摘要: An exhaust valve assembly for a two-stroke internal combustion engine has a valve actuator, and a two-part valve having a primary and secondary valves defining first and second decompression passages respectively. The primary valve is operatively connected to the valve actuator. The primary valve is in first, second and third primary valve positions when the valve actuator is in first, second and third actuator positions respectively. The secondary valve is in a first secondary valve position when the valve actuator is in the first or the second actuator position and in a second secondary valve position when the valve actuator is in the third actuator position. The first and second valve decompression passages fluidly communicate with each other when the valve actuator is in the second actuator position, and are fluidly separate from each other when the valve actuator is the first or the third actuator position.

    摘要: A reciprocating machine includes a housing (12) and piston means (20) that are cyclically relatively displaceable along an axis (11) to define a variable volume working chamber (50). There is further provided air inlet means and fuel inlet means (100) admitting air and fuel to the working chamber for forming an ignitable mixture after compression of the air therein, and means to exhaust combustion products from the working chamber. The variable volume working chamber (50) includes at least two sub-chambers, a combustion chamber (54) and a main chamber (52) mutually displaced on the axis (11) and in communication at a cross section (53) at which gas in the combustion chamber (54) may expand at least partially laterally as it flows from the combustion chamber (54) into the main chamber (52). The air admission means, the exhaust means and the chambers (52, 54) are arranged so that a swirl of gas is generated and maintained about the axis (11) in both chambers (52, 54) during operation of the machine. The combustion chamber (54) is sealed and defined laterally and at one end by integral heat resistant and/or low thermal conductivity wall structure (40) having a surrounding heat insulation jacket (48) and associated heat dissipation means (47, 49) arranged so that, during operation of the machine, the surfaces (42a, 44) of the wall structure bounding the combustion chamber are maintained at a temperature which is substantially higher than wall surfaces (31) bounding the main chamber (52).

    摘要: A two-cycle, two-cylinder (10), (12) opposed piston (14), (16), (18), (20) internal combustion engine having means for continuously adjusting the stroke of the engine and the blocking and unblocking of intake (88), (92), transfer (90) and exhaust (102) ports with respect to each other as the engine is operating. Corresponding pistons of each cylinder are connected to respective ends of pivotally mounted rocker arms (24) or (24'), and (34) so that pistons in one cylinder move oppositely with respect to pistons in the other cylinder, the piston side surfaces alternately blocking and unblocking transfer and exhaust ports. In a particular embodiment, the rocker arms (24') are each fitted with a flat spring (154) or (154') positioned so as to be in contact with the end of the associated piston rod and deflecting to allow the pistons to move apart at an increased speed in advance of the crankshaft. The springs (154) and (154') are secured and limited so as to provide increasing spring moment as the springs are deflected. Two connecting rods (48) and (59) are provided, one of which is attached at one end to each of the rocker arms at a pivot point distal from the rocker arm pivotal mount (26) or (36) and at the other end to a rotatably mounted eccentric (52), one end of which is formed into a shaft (54) containing a power drive gear (56) operatively connected to a drive shaft (60), the eccentric being rotated due to an up and down motion of the connecting rod. Means (47), (50) and (63), (64) are provided for continuously varying the attachment points of the connecting rods to the rocker arms, thereby altering the allowable pivotable movement of the rocker arm and consequently the stoke or maximum spaced-apart distance of the pistons in each cylinder. Also, the shaft portion (54) of one of the eccentrics forms twisted splines on its outer surface, its associated power drive gear being (56) adapted to mesh with the twisted splines so that the gear is rotated as it is longitudinally displaced along the shaft. Means (104), (106) are provided for continuously displacing this gear thereby changing the angular relationship between the two rocker arms, and thus the relative positioning of the pistons contained in each cylinder. This changed position alters the blocking of the exhaust ports with respect to the unblocking of the transfer ports. Remote combustion chamber (128), (129) and a means (136), (138) for ensuring that the volume in which combustion takes place remains substantially constant during the combustion process.
