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.

摘要： A Stirling cycle machine with a liquid fuel/gaseous fuel burner. The burner may include a preheater to capture the thermal energy of the exhaust. The burner directs the preheated air to each burner head, where it enters a prechamber. Each burner head includes a fuel nozzle that directs liquid or gaseous fuel into the prechamber. The prechamber is fluidically connected to a combustion chamber via a prechamber nozzle that has a smaller opening than the prechamber. The burner head ignites the fuel air mixture in the prechamber with an ignitor located above or within the prechamber. The flame is initially lit as a diffusion flame in the prechamber. The flame is pushed out of the prechamber into the combustion chamber by an increased air flow rate. The liquid fuel from the nozzle now evaporates in the prechamber and forms a prevaporized flame in the combustion chamber.

摘要： An opposed-piston engine with a single crankshaft has a rocker-type linkage coupling the crankshaft to the pistons that utilizes a rotatable pivot rocker arm with full-contact plain bearings. A rocker-type linkage utilizes a rotatable pivot bearing with an eccentric aspect to vary translation of piston linkage along the axial direction of a cylinder, which shifts the top dead center (TDC) and bottom dead center (BDC) locations of a piston so as to change the volume of charge air compressed during the power stroke.

摘要： An opposed-piston, opposed-cylinder engine is disclosed that has the pistons symmetrically arranged in the opposed cylinders. In one embodiment, the inner pistons are exhaust pistons and the outer pistons are intake pistons. Alternatively, the inner pistons are intake pistons and the outer pistons are exhaust pistons. The pistons are coupled to the crankshaft that is situated between the opposed cylinders. Central axes of the two cylinders are offset by a predetermined distance. The connecting rods that couple between the crankshaft and the pistons are arranged adjacent to each other on journals of the crankshaft. The journal to which the pushrods couple is not a split-pin type. Instead, it is one that has a common central axis. Furthermore, the crankshaft is a one-piece or unitary structure.

摘要： An opposed piston, internal-combustion engine including a cylinder with a bore and opposed pistons disposed within the bore is provided with one or more hypocycloidal drives that convert the linear motion of a piston to rotary output motion. An electrical generator includes an opposed piston, internal-combustion engine with a coil mounted to the skirt of a piston and a hypocycloidal drive connected by a rod to the piston. The construction of the hypocycloidal drive imposes a sinusoidal period on the linear motion of the piston. As the piston transports the coil though a magnetic field, a sinusoidal voltage is induced in the windings of the coil.

摘要： Working cycle for internal combustion engines, with methods and apparatuses for managing combustion charge density, temperature, pressures and turbulence (among other characteristics). At least one embodiment describes a supercharged internal combustion engine in which a supercharging portion of air is compressed, cooled and injected late in the compression process. A sub-normal compression ratio or low “effective” compression ratio initial air charge is received by a cylinder/compression chamber on the engine intake process, which during compression produces only a fraction of heat-of-compression as that produced by a conventional engine. During compression process, dense, cooled supercharging air charge is injected, adding density and turbulence above that of conventional engines with low “effective” compression ratio for this portion of air charge also. Compression continues and near piston top dead center, the air charge being mixed with fuel is ignited for power pulse followed by scavenging.

摘要： The invention is concerned with a method of deriving mechanical work from a combustion gas in internal combustion engines and reciprocating internal combustion engines for carrying out the method. The invention includes methods and apparatuses for managing combustion charge densities, temperatures, pressures and turbulence in order to produce a true mastery within the power cylinder in order to increase fuel economy, power, and torque while minimizing polluting emissions. In its preferred embodiments, the method includes the steps of (i) producing an air charge, (ii) controlling the temperature, density and pressure of the air charge, (iii) transferring the air charge to a power cylinder of the engine such that an air charge having a weight and density selected from a range of weight and density levels ranging from below atmospheric weight and density to heavier-than-atmospheric weight and density is introduced into the power cylinder, and (iv) then compressing the air charge at a lower-than-normal compression ratio, (v) causing a pre-determined quantity of charge-air and fuel to produce a combustible mixture, (vi) causing the mixture to be ignited within the power cylinder, and (vii) allowing the combustion gas to expand against a piston operable in the power cylinders with the expansion ratio of the power cylinders being substantially greater than the compression ratio of the power cylinders of the engine. In addition to other advantages, the invented, method is capable of producing mean effective cylinder pressures ranging from lower-than-normal to higher-than-normal. In the preferred embodiments, the mean effective cylinder pressure is selectively variable (and selectively varied) throughout the mentioned range during the operation of the engine. In an alternate embodiment related to constant speed-constant load operation, the mean effective cylinder pressure is selected from the range and the engine is configured, in accordance with the present invention, such that the mean effective cylinder pressure range is limited, being varied only in the amount required for producing the power, torque and speed of the duty cycle for which the engine is designed.

摘要： The engines may be of either the swing beam or the rocker beam type and each has its crankshaft in a central, transverse plane of the block. Each engine has at least one pair of cylinders with each having a piston and a head. A link pivotally connected to each piston is connected to the appropriate one of a pair of beams, one on each side of the central plane and each pivotally connected to the block. Each beam is pivotally connected to the appropriate one of the crankshaft connecting rods. The moving paired parts, i.e. the pistons, links, beams and connecting rods, are so formed and positioned with reference to the central transverse plane that a plane inclusive of any feature of the moving parts and the crankshaft axis defines an angle with respect to a plane inclusive of the corresponding feature on the opposite side of the central plane and the crankshaft axis that does not exceed .+-. 4.degree. and the perpendicular radial distance between corresponding features of the moving parts and the crankshaft axis differ by no more than .+-. 8%. The working surfaces of the block constraining the motion of the moving parts are subject to the same limitations. The moving parts on each side of the central plane may be axially aligned or axially offset. In all embodiments of the invention, the crankshaft axis is an axis of symmetry and the engine possesses effective dynamic balancing properties.
