摘要： An internal combustion engine including internal cavities slidingly receiving a respective piston to define a respective combustion chamber, at least one inlet port for each internal cavity in fluid communication with the combustion chamber at least during the intake phase and a beginning of the compression phase, at least one exhaust port for each of the internal cavities and in fluid communication with the combustion chamber during the exhaust phase, a plenum for receiving pressurized air, and conduits in fluid communication with the plenum. Each conduit defines a fluid communication between a first respective internal cavity and a second respective internal cavity through the inlet ports. The combustion chamber of the first respective internal cavity undergoes the beginning of the compression phase simultaneously with the combustion chamber of the second respective internal cavity undergoing the beginning of the intake phase.

摘要： A reciprocating compressor. A hollow cylinder tube contains a piston assembly having two pistons connected by a piston rod. At each end of the cylinder tube is an outer chamber between an end plate and an outer end of the proximate piston. These two outer chambers and the outer ends of the pistons define a power cylinder at each end of the cylinder tube. In the mid-portion of the cylinder tube, a center divider is situated between the pistons and has an aperture that allows the piston rod to reciprocate through it. The two inner chambers formed thereby and the inner ends of the pistons define two compression cylinders in the mid-portion of the cylinder tube. The two compression chambers share a suction manifold and a discharge manifold, but have independently operating suction and discharge valves.

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. The push rod extends through an inner pumping chamber in the fluid pumping assembly and forms a fluid plunger within this chamber. 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 in-line, two-cycle, crankcase compression, internal combustion engine having a plurality of scavenge ports and an exhaust port for each cylinder in which an exhaust control valve is positioned. To permit a compact assembly, the ports are rotated about the cylinder bore axis in a transverse plane so that the exhaust ports extend at an acute angle to a common plane containing the cylinder bore axes and the control shafts for the exhaust control valves extends perpendicularly to this plane. A wide variety of actuators are disclosed for operating the exhaust control valves simultaneously including flexible transmitters and a linkage system.

摘要： An internal combustion 2-stroke engine having at least one combustion chamber equipped with a delayed fuel supply system opening into a cylinder head. A wall of the cylinder has at least one exhaust port situated in the vicinity of a first referernce point through which passes a first axial plane of the cylinder or exhaust plane and at least one intake port situated in the vicinity of a second reference point, or intake reference point. A plane perpendicular to the exhaust plane and containing the axis of the cylinder defines two accommodation zones in the cylinder with the first accommodation zone, complementary to the second one, containing the reference point of the exhaust port, and the supply system is situated in the second accommodation zone.

摘要： An idling system for a multi-cylinder two-stroke engine as used in an outboard motor. Through a porting arrangement in the carburetor of at least one of the cylinders, the fuel supplied to that cylinder at idle and off-idle speed is reduced to a value so that the fuel-air ratio is too lean to fire. On rapid acceleration from idle speed, a charge of fuel is injected directly to the non-firing cylinder to provide smooth acceleration.
