2. A novel two-stroke internal combustion engine as set forth in claim 1 wherein: the exhaust valve seat can be designed into a flat type or a V-shaped type, and the flat type is that the movable inner cylinder sleeve slightly swings in the outer cylinder sleeve; the exhaust valve seat is adjustable, controllable up and down, and can change the volume of the combustion chamber to reduce and increase power.
3. A novel two-stroke internal combustion engine as set forth in claim 1 wherein: the outside of the movable inner cylinder sleeve is wound with a coil to obtain an electromagnet, the opening and closing of an exhaust valve are controlled by a computer to obtain a variable compression ratio, and the volume of the air compression cylinder can be increased by several times to obtain the purpose of double pressurization.
4. A novel two-stroke internal combustion engine as set forth in claim 1 wherein: the controllable intake valve is a one-way valve for controlling the air inflow.
5. A novel two-stroke internal combustion engine as set forth in claim 1 wherein: the fuel varieties available to the body include diesel, gasoline and liquefied gas.
6. A novel two-stroke internal combustion engine as set forth in claim 1 wherein: the machine body can be in a shape of straight line, V shape and horizontal opposite; the number of cylinders of the machine body can be single cylinder, two cylinders, four cylinders, eight cylinders and more.
7. An internal combustion engine comprising the novel two-stroke internal combustion engine and not using the crankshaft and the connecting rod, characterized in that: the internal combustion engine is composed of two long cylinder sleeves in parallel, a bearing seat is respectively arranged in the middle of two sides of each long cylinder sleeve, a steel pipe is respectively arranged in each long cylinder sleeve, a long toothed hole and a long non-toothed hole are respectively arranged on two sides of each steel pipe, a convex piston is respectively arranged at two ends of each steel pipe, the two steel pipes with the convex pistons are respectively arranged in opposite directions to counteract vibration, a shaft with circular teeth in the middle is arranged in the middle of each steel pipe, the shaft respectively penetrates through the two outer cylinder sleeves and the steel pipes with the long teeth, the teeth on the steel pipes are respectively meshed with the teeth on the middle shaft in opposite directions to perform shaft rubbing motion, when the piston reaches an upper dead point and a lower dead point, the steel pipes are driven to rotate for two tooth pitches by inertia of a flywheel on the shaft, the teeth on two sides of the steel pipes are interchanged, a clamping pin is arranged on the other side of the steel pipes, when the long, the other side is pressed back, when the teeth on the two sides are interchanged, the clamping pins are also interchanged in a spring-out mode, so that the shafts rotate in the same direction, and the meshed teeth cannot be separated.
