Abstract

The utility model relates to a cylinder body with white iron net lines for an internal-combustion engine, and is composed of a cylinder in the upper surface of the cylinder body and white iron net lines on the surface of the cylinder body. The utility model has simple structure, easy production and manufacture and wearing resistance; the service life of the internal-combustion engine can be effectively extended, and the energy can be saved; the environment pollution is reduced, which is favorable for environment protection.

Description

Cylinder body with white iron net lines

This use is novel to relate to the cylinder block of the band white iron reticulate pattern used on a kind of internal-combustion engine.

At present, mostly cylinder surface on the cylinder block of some internal-combustion engines is the smooth flat that formed by cast iron, this form makes has only ten thousand kilometers of 4--6 the working life of interior machine, through overhaul, life-span is shorter, generally have only ten thousand li of 1--3, cylinder is with regard to heavy wear, a large amount of lubricating oil carry-overs, power descends, and oil consumption increases, smolder and seriously, both polluted air, wasted the energy again, the generation of this phenomenon mainly is that the cylinder surfaces hardness of cast-iron cylinder block is too low, has only Rockwell (HRC) 20-25 through measurement.So not wear-resisting, the life-span is short, fault is many.

The purpose of this utility model just provides a kind of cylinder block of improved novel band white iron reticulate pattern.

The purpose of this utility model is achieved like this, with the argon tungsten arc cylinder surface in the cylinder block is quenched, make its surface covert at the local metal that quenches, become the big white iron of hardness by common alloy cast iron, quenching is that the reticular structure form is carried out, thereby forming with white iron is the cylinder block surface of the white iron reticulate pattern of material, so just constitutes the cylinder of band white iron reticulate pattern, and cylinder body, cylinder and white iron reticulate pattern constitute the cylinder block of novel band white iron reticulate pattern.

The utility model is simple in structure, and is wear-resistant, and long service life is fuel-efficient, and atmospheric pollution is few, remarkable in economical benefits.

Below in conjunction with accompanying drawing structure of the present utility model is elaborated.

Fig. 1 is a structure front elevation of the present utility model.

Fig. 2 is a plan view of the present utility model.

Fig. 3 is a cylinder of the present utility model position sectional view.

Shown in Fig. 1,2,3, structure of the present utility model is, cylinder 1 is arranged on cylinder body 2, there is white iron reticulate pattern 3 on cylinder 1 surface, white iron reticulate pattern 3 is to adopt the argon tungsten arc cylinder surface to be carried out netted quenching and the white iron material formation of covert one-tenth, because electric arc quenches in the extremely short time the cast iron smelting of cylinder surface electric arc place of arrival, make cast iron in a disguised form be white iron, in a disguised form be the netted line of white iron promptly, thereby constitute the cylinder block of novel band white iron reticulate pattern by common grey alloyed iron cast iron.

The former cast iron hardness of the utility model hardness ratio improves greatly; can reach Rockwell 50-55; improved wear-resistant degree effectively; prolonged internal-combustion engine working life; can reach the 10-15 kilometer, and when installing and using, also can dwindle fit up gap with piston; cylinder pressure is improved; reduce lubrication oil consumption, power increases, and oil consumption reduces; can save a large amount of energy; reduced the waste of human and material resources, financial resources, exhaust pollution reduces, and helps environmental protection; economic benefit and obvious social benefit, it is applied and must be welcome by society.

Claims (2)

1, the cylinder block of the band white iron reticulate pattern that is made of cylinder body and cylinder, there is white iron reticulate pattern (3) on cylinder (1) surface in it is characterized in that above the said cylinder body (2).

2, the cylinder block of band white iron reticulate pattern according to claim 1, the white iron reticulate pattern (3) that it is characterized in that are to adopt the argon tungsten arc cylinder surface to be carried out netted quenching and the white iron material formation of covert one-tenth.
