Problems solved by technology

[0008] However, in the crank-slider mechanism, the traditional crank-connecting rod structure is replaced by the crank-slider motion conversion mechanism, the body of the traditional two-stroke internal combustion engine cannot directly apply the crank-slider structure, and a new body needs to be designed

Embodiment 1

[0028] figure 1 It is one of the isometric views of the first embodiment of the body of the two-stroke crank and slider internal combustion engine of the present invention.

[0029] Please refer to figure 1 , In an embodiment of the present invention, the body 1 of the two-stroke crank-slider internal combustion engine is integrally formed with a cylinder head (not marked), and several comb-shaped cooling fins 2 are also arranged on the cylinder head. Wherein the cooling fin and the cylinder head are also integrally formed. Of course, the cylinder head and the engine body 1 can also adopt a split structure, and the heat sink 2 can also have other shapes.

[0030] The two-stroke crank-slider internal combustion engine body 1 of the embodiment of the present invention has a cylindrical side wall, and the space enclosed by the inner surface of the side wall is close to the cylinder head and forms the cylinder of the internal combustion engine. The piston can be placed in the c...

Embodiment 2

[0045] image 3 It is one of the isometric views of the second embodiment of the body of the two-stroke crank-slider internal combustion engine of the present invention; Figure 4 It is the second axonometric view of the second embodiment of the body of the two-stroke crank and slider internal combustion engine of the present invention.

[0046] The difference between this embodiment and the above-mentioned first embodiment is that the guide component is a guide plate. Such as image 3 and Figure 4 As shown, a guide plate 5a is provided at the air inlet 4a, and the size of the guide part 5a along the cylinder circumference is larger than that of the figure 1 Dimensions of guide post 5 shown in . Therefore, it can better provide guidance to the piston arranged in the cylinder, which is beneficial to the stable work of the piston. Preferably, the guide plate 5a can be set to be coplanar with the inner peripheral surface of the side wall of the machine body and have the sam...

Abstract

The invention discloses a two-stroke crank circular sliding block internal-combustion engine body, comprising an exhaust channel which is arranged on the engine body and communicated with a cylinder and an air inlet channel communicated with a crank accommodating space below the cylinder; the engine body is also provided with two opposite through holes, namely crank bearing set holes; central connecting lines of the two crank bearing set holes pass through the crank accommodating space and is perpendicular to the central axial line of the cylinder; and an opening of the air inlet channel, which is positioned at the inner side of the engine body, is named as an air inlet, and a guide component is arranged at the air inlet and arranged along the reciprocating direction of a piston of the internal-combustion engine. The engine body can be applied to the two-stroke crank circular sliding block internal-combustion engine. The invention also provides a two-stroke crank circular sliding block internal-combustion engine.

Description

technical field [0001] The invention relates to a crank and slider internal combustion engine, in particular to a two-stroke crank and slider internal combustion engine body. The invention also relates to a crank circular slider internal combustion engine. Background technique [0002] In conventional internal combustion engines and compressors, the conversion between the reciprocating motion of the piston and the rotational motion of the crankshaft is achieved by a crank-and-rod mechanism. However, in the crank-link mechanism, due to the existence of the connecting rod, the internal combustion engine and the compressor of the crank-link mechanism have defects such as bulky, heavy, and poor balance performance. [0003] In order to solve the problems referred to above, the Chinese patent whose approval announcement date is January 13, 1988 and whose announcement number is CN85200358B discloses a "crank circular slider reciprocating piston internal combustion engine". The d...
