Problems solved by technology

[0004] In order to solve the problem of the optical engine, the traditional steel piston ring is easy to scratch the transparent cylinder liner due to its high rigidity, and the piston ring made of graphite is difficult to ensure the seal between the cylinder wall and the cylinder wall due to its small elasticity. In the process, the graphite ring is easy to break, causing the defect of loss. The invention provides a piston ring for an optical engine

Embodiment 1

[0014] Embodiment 1, as shown in Fig. 1, Fig. 2, Fig. 3, present embodiment is the piston ring used on a kind of optical engine, and this piston ring comprises the outer ring 3 that is made of graphite material and has elastic inner ring 2, The inner peripheral surface of the outer ring 3 is provided with an arc groove 6 , the inner ring 2 has an inner ring opening 1 , and the inner ring 2 is set in the arc groove 6 . In this embodiment, as shown in FIG. 3 , the outer ring 3 is composed of two graphite semicircular rings merged together, and has two outer ring openings 5 ​​. The inner ring 2 is a split ring made of nickel alloy material, as shown in FIG. 2 . During assembly, the inner surface of the inner ring 2 and the inner surface 4 of the outer ring are kept on the same circumferential surface. The relative positions of the outer ring opening 5 and the inner ring opening 1 form a set angle. Preferably 90 degrees.

[0015] The assembly process of this embodiment is as fo...

Abstract

The invention discloses a piston ring for an optical controlled engine, which comprises an outer ring which is made of graphite and an inner ring with elasticity, wherein the inner circumferential surface of the outer ring is provided with an arc groove, the inner ring is provided with an internal ring opening, and the inner ring is arranged inside the arc groove. The piston ring for the optical controlled engine consists of the outer ring and the inner ring, the inner side of the graphite outer ring is provided with the arc groove, and the outer ring is attached onto the inner ring through the groove, so the leak tightness of the piston ring is greatly improved, and the work pressure of the combustion chamber is effectively ensured. At the same time, the graphite has self-lubrication effect and good heat conduction, so the lubrication between the piston ring and a transparent cylinder sleeve is ensured, and the temperature of the transparent cylinder sleeve caused by the friction can be reduced.

Description

technical field [0001] The invention relates to a piston ring of an engine, in particular to a piston ring for an optical engine. Background technique [0002] Optical engine (Optical engine) is also known as visual engine or transparent engine (Transparent engine). Generally, the piston and cylinder liner are made of transparent quartz, and then the laser is used to illuminate the mixed gas in the cylinder or other components through the visualization window (piston or cylinder liner). Gas, and then use a high-speed camera to shoot the situation in the cylinder. The optical engine is mainly used to study the gasoline direct injection engine or diesel engine, to study the spray situation in the cylinder, the formation of the mixture gas and the combustion process. [0003] At present, in the optical engine, the cylinder liner is generally made of transparent quartz glass. The cylinder liner is under unstable high temperature and high pressure, and has to withstand the mechan...
