摘要： A free piston engine is configured with a pair of opposed engine cylinders located on opposite sides of a fluid pumping assembly. An inner piston assembly includes a pair of inner pistons, one each operatively located in a respective one of the engine cylinders, with a push rod connected between the inner pistons. An outer piston assembly includes a pair of pistons, one each operatively located, in a respective one of the engine cylinders, with at least one pull rod connected between the outer pistons. The pull rod extends through an outer pumping chamber in the fluid pumping assembly and forms a fluid plunger within this chamber. Each outer piston cooperates with an integrated scavenge pump in order to compress the charge air, thus significantly increasing the air charge density into the engine cylinders for each stroke of the engine.

摘要： An internal combustion piston engine for operation with gaseous and/or liquid fuel comprises at least first and second working cylinders associated with each other, with their working pistons movable in opposite relationship, and a fuel supply system which is operable to compress the fuel and which for each working cylinder has a piston compressor associated therewith at the cylinder head end. Each compressor has a cylinder and a differential piston axially movably accommodated in the compressor cylinder. The larger surface of the differential piston is subjected to the pressure in the combustion chamber of the associated working cylinder while the smaller surface of the differential piston is operable to compress the fuel when the pressure rises in the working cylinder combustion chamber. Extending between the compression chamber of the piston compressor and the combustion chamber of the associated working cylinder is at least one flow transfer path which has an opening into the combustion chamber, the opening being disposed in the path of movement of the differential piston and being adapted to be opened and closed by a control edge thereof. The differential pistons of the associated compressors are positively coupled in opposite relationship.

摘要： A two-stroke combustion engine is described which has a symmetrical, floating differential piston (14), having at least two main piston portions (16, 18), each movable in a combustion chamber (28, 30) formed with exhaust ports (46), and each connected to a pre-compression chamber (34, 36) by means of a respective channel (38, 40). The combustion chambers (28, 30) are arranged axially inward of the piston portions and between the chambers lies the pre-compression chamber (32) in which a central double-acting piston portion (22) of the differential piston (14) is arranged on a piston rod (20). The central piston portion (22) divides the pre-compression chamber (32) into two separate supercharging chambers (34, 36), from which the channels (38, 40) leading to the combustion chambers (28, 30) terminate at the end walls of the respective combustion chambers. Valve means (24, 26) on the piston rod (20) serve to open and close the channels so that upon expansion occurring in one combustion chamber material exchange will occur in the other.

摘要： An internal combustion engine operating on a two-stroke cycle and including a piston 1 reciprocable in a cylinder 2 to drive a crank shaft and also to inhale and compress a volume of air is characterized by a second piston 15 working in a separate cylinder 13 co-axial with and opposed to the first cylinder 2, the piston 15 being synchronized with the first piston 1. The second piston 15 acts to introduce a compressed charge of mixture of air and fuel through a non-return valve 30 into a relatively small ignition chamber 34 including a sparking plug 35 and communicating with a combustion chamber 11 in the head of the cylinder 1. The piston 15 draws air/fuel mixture along an inlet passage 20, past a non-return reed valve 21 and into a crank case 22. On the return stroke of the piston 15 the mixture passes through passages 23 in the piston controlled by a non-return valve 24 and also along passages 14 and around the piston. The next stroke of the piston 15 compresses the charge of mixture and forces it through the valve 30 which generates turbulence prior to ignition.
