摘要： The present invention provides a novel internal combustion engine design and methods for using the same. The internal combustion engine of the present invention may include two rotors on which the pistons and cylinders and pistons are mounted, respectively. A plurality of cylinders mounted on a cylinder rotor, and a plurality of pistons mounted on a piston rod rotor, where the arrangements of the pistons and cylinders are complementary and each piston is paired with one of the cylinders. The cylinder rotor and the piston rod rotor may be position at oblique angle relative to one another, such that their central axes are located on a same plane, but the axes are not coaxially aligned and intersect on that plane.

摘要： An internal combustion engine, including a pair of opposed pistons, a pair of opposed cylinders, and an output shaft, wherein each of the pistons is arranged for reciprocating motion within a respective one of the cylinders, driven by combustion, and the pistons are coupled to the output shaft by a coupling such that said reciprocating motion of the pistons drives rotation of the output shaft, wherein the coupling includes a unitary connecting rod coupled to the opposed pistons, the connecting rod having side guides for guiding a slider bearing located for reciprocating movement relative to the connecting rod, and the coupling further includes a crankshaft rotatably mounted within the slider bearing, the crankshaft having at least one guide shoulder for supporting axial location relative to the slider bearing.

摘要： An engine balancing system includes an engine body. At least two slider-crank mechanisms are provided inside the engine body. One of the slider-crank mechanisms is arranged opposite to the other slider-crank mechanism. A slider in one of the slider-crank mechanisms is moved at a speed and acceleration similar to a speed and acceleration of a slider in the other slider-crank mechanism. The slider-crank mechanism includes a connecting rod and a crankshaft with a crank. One end of one of the slider-crank mechanisms and one end of the other slider-crank mechanism are connected to the same crankshaft through the crank. The balancing system can effectively eliminate first-order, second-order and higher-order vibrations generated during engine operation, thus reducing the probability of equipment damage.

摘要： An internal combustion engine includes a hollow cylinder, a piston within the hollow cylinder, and a cylinder head. A base valve assembly at a base of the hollow cylinder permits or restricts fluid flow from an intake manifold into a sub-chamber below the piston. The piston includes at least one intake port connecting a combustion chamber above the piston with the sub-chamber, and a transfer valve that opens and closes the at least one intake port. When the transfer valve opens the at least one intake port, fluid is permitted to flow from the sub-chamber to the combustion chamber. The internal combustion engine operates according to a four-stroke piston cycle, wherein multiple intake stages are provided. The intake stages may include intake of air into the sub-chamber during a compression stroke, transfer of air from the sub-chamber to the combustion chamber during a power stroke, intake of air-fuel mixture into the sub-chamber during an exhaust stroke, and transfer of air-fuel mixture from the sub-chamber to the combustion chamber during an intake stroke.

摘要： An opposed piston engine has a driveshaft with at least one combustion cylinder positioned between opposing, curvilinear shaped cams mounted on the driveshaft, where the center axis of the combustion cylinder is parallel with but spaced apart from the driveshaft axis. A piston assembly is disposed in each end of the cylinder, with one piston assembly engaging one cam and the other piston assembly engaging the other cam. Each piston assembly includes a cam follower that can move along a curvilinear shaped cam to reciprocate the piston assembly within the cylinder. The combustion cylinder includes an intake port in fluid communication with an annular intake channel formed in the engine block in which the cylinder is mounted, and an exhaust port in fluid communication with an annular exhaust channel formed in the engine block.

摘要： An internal combustion engine may include a first piston reciprocatingly disposed in a first cylinder, a combustion chamber fluidly coupled with the first cylinder, and an ignition source at least partially disposed within the combustion chamber. An intake valve may provide selective fluid communication between an intake system and the combustion chamber, an exhaust valve may provide selective fluid communication between an exhaust system and the combustion chamber. A second piston may be reciprocatingly disposed within a second cylinder, configured to draw a fluid into the second cylinder via a fluid inlet, and expel the fluid via a fluid outlet. A pressure accumulator may receive the fluid from the second cylinder and provide a reservoir of pressurized fluid. A crankshaft may be coupled with the first piston and the second piston for rotational motion associated with reciprocating movement of the first piston and the second piston.

摘要： An internal combustion engine has a casing and a piston arrangement including a piston coupled to a track. The track is coupled to a shaft and has an inner cam surface and an outer cam surface. The piston is coupled to the track by followers which run on the respective inner and outer cam surfaces of the track to control motion of the piston. A sliding element is connected to the piston and extends below the piston head having a profiled slider surface which engages a corresponding profile in the casing. Also, the casing includes at least two plates having a cutout for receiving the track and a bore for receiving the shaft, and at least two end plates coupled transverse to the plates. At least one cylinder bore is formed in the end plates, and the piston is arranged to move in reciprocating motion in the cylinder bore.
