Embodiment Construction
[0022] Please see Figure 1-Figure 3 , the above figures are all perspective views of the internal combustion engine body provided by the embodiment of the present invention, and the angles thereof are slightly different, reflecting the structure of the high-temperature section of the cylinder of the body concerned in the present invention. This block has no cylinder liners installed. The internal combustion engine body in this embodiment is an internal combustion engine body using a crank-slider mechanism or an end shaft-moving shaft mechanism. In fact, the technical solution proposed in this embodiment can also be used in a crank-connecting rod internal combustion engine.
[0023] As shown in the figure, the body is an H-type four-cylinder engine body, which includes a first cylinder 1 , a second cylinder 2 and a runway 3 . The axes of the first cylinder 1 and the second cylinder 2 are parallel to each other, and the axis of the raceway 3 is perpendicular to the axes of the...

The invention provides a body used by a conversion device without connecting rod reciprocating-rotating motion. An annular concave water jacket groove is arranged on the inner wall of a cylinder at the matching part of the body and a cylinder jacket, and the water jacket groove is matched with the outer radial surface of the cylinder jacket placed in the cylinder to form an annular water jacket; at least one lug boss is arranged at the bottom of the water jacket groove, and after the cylinder jacket is placed, the top surface of the lug boss can be in contact with the outer radial surface of the cylinder jacket; and the lug boss can not separate the annular water jacket cavity and is called a cylinder jacket supporting lug boss. The invention simultaneously provides an internal combustion engine and a compressor using the body. In the body of the conversion device without connecting rod reciprocating-rotating motion, which is provided by the invention, at least one cylinder jacket supporting lug boss is arranged at the bottom of the water jacket groove at the high-temperature section of the cylinder, and the cylinder jacket supporting lug boss can be in contact with the outer radial surface of the cylinder jacket and can support the side wall surface of the cylinder jacket, thereby obviously prolonging the service life of the cylinder jacket.
Description
technical field [0001] The invention relates to a reciprocating-rotational conversion device, in particular to a body of the reciprocating-rotational conversion device without connecting rods; the invention also relates to an internal combustion engine and a compressor using the body. Background technique [0002] The internal combustion engine is a widely used power source at present. This kind of equipment can effectively convert the chemical energy stored in combustibles into mechanical energy, especially the chemical energy contained in gasoline and diesel oil, etc. can be effectively converted into mechanical energy. [0003] Under the existing common technology, the internal combustion engine movement mechanism basically adopts the crank-connecting rod engine. Since this kind of engine needs to use the connecting rod as a transition piece between reciprocating motion and rotary motion, the size of the piston motion track direction is increased, making it difficult to ob...
