Abstract

Provided is a device for treating the inner surface of a cylinder barrel. A cover member (32) is provided, at the lower surface (59) thereof, with seal rings (54, 55, 56). The seal rings (54, 55, 56) are disposed concentrically about the center axis (63) of a cylinder barrel (43, 67). The lower ends of the seal rings (54, 55, 56) are disposed at different levels of height in such a manner that the farther away from the center axis (63), the higher the positions of the lower ends relative to the seal ring (54) closest to the center axis (63).

Description

technical field [0001] The present invention relates to a surface treatment technology of a cylinder provided on a cylinder body by bringing a treatment liquid into contact with the inner surface of the cylinder to treat the inner surface. Background technique [0002] Since the inner surface of the cylinder bore of the engine is exposed to high heat caused by the friction of the piston rings and the combustion of fuel, there is a demand for strength on the surface. In order to improve the surface strength, it is effective to perform surface treatment. In the case of performing plating treatment which is one of the surface treatments, it is required to remove dirt and the like on the surface in advance before the plating treatment. In this way, the treatment of removing dirt and the like prior to surface treatment is called pretreatment. exist Figure 11 An example of the pretreatment of the plating treatment is described in . [0003] Such as Figure 11 As shown, the pre...
