Embodiment Construction

[0013] The present invention will be further described now in conjunction with accompanying drawing. These drawings are simplified schematic diagrams only to illustrate the basic structure of the present invention in a schematic way, so they only show the components relevant to the present invention.

[0014] Such as figure 1 and figure 2 The novel internal-combustion engine shield ring shown comprises a shield ring body 1, and the inner wall of the shield ring body 1 is composed of a stepped upper inner wall 2 and a lower inner wall 3, and the outer wall of the shield ring body 1 is vertically provided with an annular groove 5; The lower surface of the cover ring body 1 is vertically provided with an annular V-shaped groove 4. The V-shaped groove 4 includes a first vertical section of the groove wall 41 and a first oblique line section of the groove wall 42. The first vertical section of the groove wall 41 and the first The groove walls 42 of the inclined line section are ...

Abstract

The invention discloses the technical field of accessories of an internal combustion engine, and particularly relates to a novel shield ring for the internal combustion engine. The novel shield ring for the internal combustion engine comprise a shield ring body, wherein the inner wall of the shield ring body consists of a stepped upper inner wall and a stepped lower inner wall, and an annular groove is vertically turned in the shield ring body; an annular V-shaped groove is vertically formed in the lower surface of the shield ring body; the diameter of the upper inner ring is smaller than that of the lower inner wall. The novel shield ring is simple in structure, reasonable in design, convenient in operation, higher in precision, good in dustproof effect and long in service life, is tightly matched with components of the internal combustion engine, and does not need to be changed frequently, so that the production efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of internal combustion engine accessories, in particular to a novel internal combustion engine shroud ring. Background technique [0002] An internal combustion engine is a kind of power machinery, which is a heat engine that directly converts the heat energy released by burning fuel inside the machine into power. Internal combustion engines in a broad sense include not only reciprocating piston internal combustion engines, rotary piston engines and free piston engines, but also rotary impeller gas turbines, jet engines, etc., but internal combustion engines generally refer to piston internal combustion engines. Piston type internal combustion engine is the most common with reciprocating piston type. The piston internal combustion engine mixes fuel and air and burns it in its cylinder, and the heat energy released makes the cylinder generate high-temperature and high-pressure gas. The expansion of the gas ...
