Abstract
The utility model discloses a special shaped cylinder liner, belonging to the cylinder liner used on reciprocating internal combustion engines. The utility model is composed of a cylinder liner body with a piston cavity, and is characterized in that the piston cavity is composed of a big end of an inner hole and a small end of the inner hole; the piston can do reciprocating motion in the piston cavity; the big end of the inner hole which has the inner diameter larger than the inner diameter of a standard cylinder liner is arranged at the upper part of the piston cavity; and the other parts are the small end of the inner hole which has the inner diameter smaller than the standard cylinder liner. The utility model can realize the only change of the cylinder liner instead of the piston, or can realize the only change of the new piston instead of the cylinder liner. Thus, the service life of the cylinder liner and the piston is properly prolonged, and the repair cost is saved for users. The utility model is suitable for use on reciprocating internal combustion engines.
Description
Affiliated technical field
The utility model relates to the cylinder sleeve that uses on a kind of cylinder jacket of diesel engine, particularly reciprocating internal combustion engine.
Background technique
Existing internal combustion engine cylinder jacket basic model is that cylinder sleeve bore is a uniform internal diameter straight-through type circular hole.The cylinder liner of this structure, it is exactly easy to wear that a major defect is arranged, and causes maintenance cost to increase thus.Through investigating the diesel engine of various models, easily damaged parts wherein comprises cylinder sleeve and piston.The normal use down basically wants overhaul once every year, and changing in the part will have cylinder sleeve, piston at least.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and a kind of reduction maintenance expenses is provided, the special-shaped cylinder sleeve of the internal-combustion engine in proper extension cylinder block life-span.
The technical solution of the utility model is: the special-shaped cylinder sleeve of this kind, it is made up of the cylinder sleeve body of band piston cavity, it is characterized in that forming and make piston pistons reciprocating chamber within it by big end of endoporus and endoporus small end, piston cavity top is provided with the big end of endoporus of one section internal diameter overgauge cylinder sleeve, and it is the endoporus small end of internal diameter less than the standard cylinder sleeve in part.
The beneficial effects of the utility model be since the big end of endoporus of special-shaped cylinder sleeve a bit of part of being a bit larger tham the standard cylinder sleeve is arranged, remaining hole section is slightly littler than the size of standard cylinder sleeve, so that the piston that coupling had been used, so just can only change cylinder sleeve and not change piston, when part is changed in repairing to the second time, the endoporus that dwindles may wear to the size of standard cylinder sleeve, can only renew piston and does not change cylinder sleeve.Therefore, with regard to proper extension the working life of cylinder sleeve and piston, saved repair expenses to the user.Special-shaped cylinder sleeve can use 2 years continuously, and cylinder sleeve is just changed in overhaul just for twice one time.
Description of drawings
Figure is a plan view of the present utility model.
Among the figure 1, the cylinder sleeve body, 2, the big end of endoporus, 3, the endoporus small end, 4, piston cavity.
Embodiment
As figure, existing is example with 195 diesel engine cylinder liner.Be described as follows:
The special-shaped cylinder sleeve of this kind, it is made up of the cylinder sleeve body 1 of band piston cavity 4.Form by big end 2 of endoporus and endoporus small end 3 and to make piston pistons reciprocating chamber 4 within it, piston cavity 4 tops are provided with the big end 2 of endoporus of one section internal diameter overgauge cylinder sleeve, its in the part be the endoporus small end 3 of internal diameter less than the standard cylinder sleeve, less than dimensional range at 0.18-0.25mm.The material of cylinder sleeve body 1 and other structures are same as the prior art substantially.
The big end of endoporus, internal diameter are Φ 95
+ 0.10 + 0.08Length 15mm
Endoporus small end, internal diameter are Φ 95
-0.25 -0.18Length 195mm.
