Abstract: To provide an internal combustion engine that can generate a strong swirl by increasing the amount of intake air for generating the swirl in a simple structure. In the internal combustion engine provided with a cylinder head formed with an air intake port having first and second ports, when a second intake valve for opening and closing the second port is brought into a halted state by a valve halting mechanism, a swirl is generated by intake air flowing through the first port in a combustion chamber. At a first inlet slot, the line of intersection between a first plane, which is a plan including the first inlet slot and a first orthogonal plane inclines upwardly as it approaches from the position near the outer periphery of the combustion chamber towards a second reference plane, and the first port includes a port section having a passage shape which extends substantially along a perpendicular line orthogonal to a first plane from the first inlet slot towards the upstream by a predetermined length of the passage in a plan view.

Abstract: To lighten the weight of an electromagnetic actuator and a valve-open-close mechanism by forming the stems from a lighter material than conventional. A pair of electromagnets formed of stators and coils are opposed to each other with a gap therebetween. An armature is disposed in the gap so as to be reciprocable between one electromagnet and the other electromagnet by the electromagnets. A first stem for transmitting the movement of the armature from one electromagnet toward the other electromagnet to a valve of the internal combustion engine is inserted in a guide hole formed in the stator of one electromagnet. The first stem is formed of a lighter material than the armature to lighten the weight of the electromagnetic actuator and a valve-open-close mechanism of an internal combustion engine.

Abstract: This invention is a two stroke, internal combustion, reciprocating, engine with plunger 14, made up of a number of similar working units. Each working unit is comprised of cylinder 16 that is closed at one end by cylinder head 4, and contains air inlet valve 2, power piston 22 that is connected to power output shaft 26, and plunger 14. Plunger 14 is a movable wall with barrel 10 attached to it. Plunger 14 moves between power piston 22 and cylinder head 4, and the means to accomplish this are: spring 12, the urging of power piston 22 after a collision, and the difference between the internal and external engine pressures. During the compression stroke the pressure inside the engine exceeds the pressure outside of the engine, this pressure difference on the exhaust area forces plunger 14 up against cylinder head 4 and deforms spring 12. During the expansion stroke the pressure difference continues to keep plunger 14 up against cylinder head 4 and spring 12 deformed. This condition will continue until the pressure force from the pressure difference on the exhaust area falls below spring 12 force. Near the end of the expansion stroke power piston 22 reaches pressure reducing chamber port 32. When power piston 22 reaches pressure reducing chamber port 32 the pressure is reduced because of the added volume of pressure reducing chamber 8, and the pressure force falls below spring 12 force. Spring 12 opens exhaust valve 6. Since exhaust valve 6 is connected to plunger 14, spring 12 resuming its undeformed state moves plunger 14 towards power piston 22. While plunger 14 moves toward power piston 22 plunger 14 sucks in the working fluid and pushes the exhaust gases out of cylinder 16. After the meeting of power piston 22 and plunger 14, pressure reducing chamber port 32 is recovered and compression begins. To provide regeneration an alternating flow heat exchanger, called regenerator 30, along with protector 34, protector valve 36, and protector check valve 38 are attached to plunger 14. Protector 34 protects regenerator 30 from heat of combustion and removes regenerator 30 volume from the expansion process until the expansion pressure has fallen below the compression pressure.
