Internal cylinder body and rotary internal combustion engine

Abstract

The invention provides an internal cylinder body and a rotary internal combustion engine and belongs to the field of internal combustion engines. The internal cylinder body comprises a C-shaped internal cylinder sleeve, a sealing elastic piece and two end covers. The internal combustion engine comprises an external cylinder body, the internal cylinder body and a piston shaft assembly. The circumferential wall of the external cylinder body is provided with an air outlet, an air inlet and a sparking plug. The internal cylinder body is rotationally connected with the external cylinder body. The internal cylinder body rotates, relative to the external cylinder body, around the axis of the internal cylinder body, the axis of the internal cylinder body and the axis of the external cylinder bodyare arranged in a stagger manner, and the side wall of the internal cylinder body and the side wall of the external cylinder body are tangent to each other. The piston shaft assembly comprises pistonassemblies and a spiral frame, wherein the piston assemblies are installed on the spiral frame, the spiral frame is located in the internal cylinder body, the spiral frame is rotationally connected with the external cylinder body, and the spiral frame rotates, relative to the external cylinder body, around the axis of the spiral frame. The internal cylinder body and the rotary internal combustionengine have the beneficial effects of being small in size, small in weight, good in stability, low in manufacturing cost and oil consumption and the like.

Description

technical field

[0001] The invention relates to the field of internal combustion engines, in particular to an inner cylinder block and a rotary internal combustion engine. Background technique

[0002] The reciprocating piston internal combustion engine (oil, gas ignition engine) is an engine that converts the heat energy generated by fuel combustion into mechanical energy. The ignition engine that is commonly used now still follows the Otto cycle, that is, intake, compression, work and exhaust. In the four strokes, the compressed mixed gas is discharged by the spark plug electrode, and the mixed gas is ignited for combustion. The volume change in the cylinder of the four strokes is realized by the piston movement driven by the crank connecting rod. According to the four working processes, it can be concluded that the reciprocating piston internal combustion engine has the following disadvantages, the loss of ventilation, the delayed closing of the exhaust valve and the earl...
