Embodiment 1

[0028] figure 1 It is the axonometric view of the first embodiment of the cylinder liner of the two-stroke crank and slider internal combustion engine of the present invention.

[0029] Such as figure 1 As shown, the cylinder liner of the two-stroke crank-slider internal combustion engine of the embodiment of the present invention includes a guide side wall 1 for accommodating the piston of the crank-slider internal combustion engine and capable of moving with the piston. In this embodiment, the guide side wall 1 is a cylindrical thin-walled part, its outer peripheral surface can cooperate with the body of the internal combustion engine, and its inner peripheral surface can cooperate with the piston head and the guide part, so that the piston can move along its central axis. reciprocating motion.

[0030] The cylinder liner can also have other shapes, but no matter what the shape of the cylinder liner is, its outline needs to match the body of the internal combustion engine,...

Embodiment 2

[0039] In the above-mentioned first embodiment, the cylinder liner intake inlet 3 is provided on the cylinder liner. Although the requirement for intake air into the crankshaft accommodation space can be met, the cylinder liner intake intake 3 will inevitably Affects the guiding action of the piston. In this embodiment, a guide plate is provided at the intake inlet of the cylinder liner. Please refer to figure 2 .

[0040] figure 2 It is the axonometric view of the second embodiment of the cylinder liner of the two-stroke crank and slider internal combustion engine of the present invention.

[0041] Such as figure 2 As shown, the difference from the first embodiment above is that in the cylinder liner 1 of this embodiment, a guide plate 4 is also provided at the inlet 3 of the cylinder liner, wherein the guide plate 4 is along the Set the direction of piston reciprocating motion.

[0042] In this embodiment, the air inlet 3 of the cylinder liner is square, and the gui...

Abstract

The invention discloses a double-stroke crank round slider internal combustion engine cylinder jacket which comprises a side guide wall and two opposite through holes, wherein the side guide wall is used for guiding a reciprocating piston, and the shape of the side guide wall is matched with the engine body of the double-stroke crank round slider internal combustion engine; the two through holes are arranged on the side guide wall and used for passing through a crank shaft; the center line of the two through holes is vertical to the central axis of the cylinder jacket; and the side guide wall is also provided with an opening the arrangement position of which meets the following requirements: when the cylinder jacket is arranged on the engine body of the double-stroke crank round slider internal combustion engine, the opening is opposite to an air inlet arranged on the engine body and known as a cylinder jacket air inlet. The cylinder jacket can be applied to the double-stroke crank round slider internal combustion engine. The invention also provides a crank round slider internal combustion engine and an engine body thereof.

Description

technical field [0001] The invention relates to a crank-slider internal combustion engine, in particular to a cylinder liner of a two-stroke crank-slider internal combustion engine. The invention also relates to a crank circular slider internal combustion engine and its body. 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 combus...
