摘要： A lower link (7) is formed of two components by being divided at a dividing surface (14) including the central axis of a crank pin bearing portion (11), the two components including a lower link upper (15) with an upper pin bearing portion (12) and a lower link lower (16) with a control pin bearing portion (13). The dividing surface (14) includes a first dividing surface (14a) located more on the upper link side than the crank pin bearing portion (11) and a second dividing surface (14b) located more on the control link side than the crank pin bearing portion (11). In the lower link (7), the first dividing surface (14a) has a surface roughness larger than a surface roughness of the second dividing surface (14b).

摘要： Internal combustion engines having a split crankshaft are disclosed. The engines may also have non-circular, preferably rectangular, cross-section pistons and cylinders. The pistons may include a skirt with a field of pockets that provide a ringless, non-lubricated, seal equivalent. The pistons also may have a domed piston head with depressions thereon to facilitate the movement of air/charge in the cylinder. The engines also may use multi-stage poppet valves in lieu of conventional poppet valves. The engines may use the pumping motion of the engine piston to supercharge the cylinder with air/charge. The engines also may operate in an inverted orientation in which the piston is closer to the local gravitationally dominant terrestrial body's center of gravity at top dead center position than at bottom dead center position.

摘要： This patent discloses thrust vectoring ignition chamber engine. Thrust vectoring ignition chamber used in this engine is an annular cylinder having nozzles mounted in a way such that during fuel suction phase they are sealed and during ignition of fuel they are unsealed so that hot jets of ignited fuel escaping through nozzles cause coupled rotatory motion on the ignition chamber. Engine uses cam operated suitably modified 3-screw compressor for suction and compression of fuel and therefore do not require piston mechanism. Flywheel mounted on extension of ignition chamber functions as output of the engine. Each half rotation of flywheel completes three phases namely fuel/air suction, compression and combustion. Thus this engine fires for every half revolution and therefore can give improved power boost.

摘要： An operation system for a piston-type expander includes: a first engaging member which is fixed to an output shaft of the piston-type expander, rotates together with the output shaft, and has a first slanting surface; a second engaging member which is rotatably disposed on the output shaft, and has a second slanting surface; and a drive device which, while keeping a rotation direction of the second engaging member around the output shaft fixed, moves the second engaging member in an axial direction of the output shaft to press the second slanting surface onto the first slanting surface, converts a pressing force of the second engaging member in the axial direction into a rotational torque of the first engaging member and the output shaft at a contact surface of the first and second slanting surfaces, and causes the first engaging member to rotate together with the output shaft.

摘要： An all-terrain vehicle for civil protection activities includes a vehicle structure with at least one module for transporting persons and/or material, and a plurality of legs bearing respective wheel assemblies or track assemblies. Each leg is pivotably mounted about a first transverse axis. One first end of the leg carries a wheel assembly or a track assembly and a second end is freely mounted pivoting about the first transverse axis on a first support which is carried by the vehicle structure. An electronically-controlled actuator adjusts an angular position of the first support about a first transverse axis. Between the first support and the leg structure two spring-shock absorber assemblies are interposed, which extend along the leg.

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： 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： The present invention relates to a control device and to a control method for a vehicle drive mechanism including a moving body having a movability range regulated by two stoppers, and a sensor which senses a position of the moving body. The control device of the present invention learns an output of the sensor corresponding to a contact state of a high-rigidity stopper, and limits, to a lower level, an operation variable of the actuator for moving the moving body toward a low-rigidity stopper along with an increase in an amount of change in the output of the sensor from the contact state of the high-rigidity stopper. Then, the control device learns the output of the sensor corresponding to the contact state of the low-rigidity stopper, and controls the actuator based on the output of the sensor learned at both the stopper positions.
