Description
Technical field
The utility model is related to cylinder technical fields, having reinforced wear-resistant in particular to one kind and improve heat dissipation effect
The I. C. engine steam cylinder structure with plating titanium layer of fruit.
Background technology
In order to overcome the abrasion problems of cylinder of internal combustion engine, in the streets positive popular a kind of " cylinder body film coating agent ", as its name suggests, it is exactly
Attempt to plate thin film in cylinder inner wall.
Such cylinder body film coating agent is declared to be applicable to gasoline, diesel motor, as long as film coating agent is fallen from machine oil added holes
Enter, thin film can be formed on cylinder wall, and can be reconciled with the machine oil of various brands, fights piston together on cylinder wall
Fierce friction, galling reduction can prevent the gap between piston and cylinder wall from increasing, reduce engine and blow gas leakage and send out
Life rate avoids cylinder pressure deficiency from influencing performance output, so can begin to use from new car, can fill up on cylinder wall
Convex-concave surface reduces impedance in turn, and piston does dynamic resistance up and down and becomes smaller, and throttle can be made to become brisk naturally, and then promote power very
To oil consumption is saved, you is allowed to give the feeling of new car for change.
It should be clear that aforementioned film coating agent, one declares that film can be formed in cylinder inner wall, and two declare again can be with machine oil phase intermodulation
With, in fact, feasibility is very low, even if solvent reconciles with machine oil, and can volatilize with incendiary effect it is idle most, and
And the film coating agent after volatilization, if attempting in a manner of supplementing film coating agent at any time, not only expends use cost just as failure,
More seriously, it in the case of using effect can be obtained and do not known, for consumer, probably I guess makes an overstatement, it can only
The use feeling for meeting psychological levels uses the fuel oil of cylinder body, can not substantially obtain any help.

Therefore, compared to the use of existing film coating agent, substantive wear-resisting effectiveness can not be obtained;The utility model uses nickel
Carbon nickel silicon carbide plating mode is formed with fixed plating titanium layer 30, or the plating titanium layer using dismountable group type in cylinder inner wall
80, it allows the internal face 113 of cylinder body 10 to dig and is formed with plating titanium film, titanizing film layer on the spot, incendiary effect can be carried out in cylinder
When, reinforce wearability, heat dissipation effectiveness really, and using after abrasion, the plating titanium layer 80 of dismountable group type can give for a period of time
To unload, as soon as replacing a new plating titanium layer 80, using effect can be restored again.
Due to internal combustion engine, its operation is not this case demand emphasis, so, in the utility model not elaborate it,
Its operation mode is identical with previous internal combustion engine, repeats no more.
The above, only multiple preferred embodiments of the utility model, when the utility model cannot be limited with this
The range of implementation, i.e., it is all according to simple equivalence changes made by present utility model application the scope of the claims and embodiment content with repair
Decorations all should still belong in the range of the utility model patent covers.
