Problems solved by technology

The use of a movable cylinder liner can avoid the disassembly of the complex cylinder head system before disassembling the cylinder liner, which greatly reduces the time for cleaning the quartz window and piston ring at a time. However, due to the interference of the cylinder head, the installation space of the piston ring is limited. So limited that normal piston ring installation tools cannot be used in this condition

Embodiment Construction

[0021] Below in conjunction with accompanying drawing, the present invention will be further described:

[0022] Such as Figure 1 to Figure 6 As shown, a cylinder liner movable optical engine piston ring quick disassembly device is composed of a device body, including a guide ring 13, a thrust washer 11, a fastening bolt 12 and a nut 10, and the outer diameter d of the guide ring 13 is 1 and height h 1 The same as the quartz glass window 3 fixed on the cylinder liner 6, it is ensured that the guide ring 13 can replace the annular quartz glass window 3. The middle part of the guide ring 13 is provided with a tapered through hole, and the original quartz glass window 3 and the cylinder liner 6 ring are used. The positioning relationship between the grooves keeps the tapered through hole coaxial with the cylinder liner 6; the diameter d at the bottom of the tapered through hole 3 It is the same as the inner diameter of the cylinder liner 6, ensuring that each piston ring in th...

Abstract

The invention discloses a quick disassembly and assembly device for a piston ring of a cylinder sleeve movable optical engine. The quick disassembly and assembly device comprises a guide ring, a thrust washer, fastening bolts and nuts, wherein the outer diameter and height of the guide ring are the same as those of a quartz glass window fixed to a cylinder sleeve; a tapered through hole coaxial with the cylinder sleeve is formed in the middle of the guide ring; the bore diameter of the bottom of the tapered through hole is the same as the inner diameter of the cylinder sleeve; and the bore diameter of the tapered through hole is greater than the outer diameter of the piston ring arranged on a piston. The quick disassembly and assembly device adopts the trapezoidal section guide ring, the thrust washer and the fastening bolts and the nuts, and is fit with the position of the movable cylinder sleeve and reciprocating motion of the lengthened piston, thereby realizing the effects of quick disassembly and assembly of the piston ring.

Description

technical field [0001] The invention relates to an auxiliary dismounting device in a cylinder of an internal combustion engine, more specifically, to a quick dismounting device for a piston ring of a cylinder liner movable optical engine. Background technique [0002] The optical engine is an experimental device for studying the gas flow, oil-gas mixing and combustion process in the cylinder of an internal combustion engine. By modifying the structure of the actual engine and setting the laser introduction window and the optical measurement window, the laser measurement of the in-cylinder process can be realized. By carrying out laser testing on the optical engine, we can gain a deep understanding of the physical and chemical processes in the cylinder, provide verification for the numerical calculation model, and provide support for the development of internal combustion engine fluid mechanics and combustion theory. In addition, optical diagnosis can be widely used in the ac...
