Problems solved by technology

In the working process of optical engines, especially combustible optical engines, the seal between the transparent window of the head and the piston and the lubrication between the piston and the cylinder wall are very important. However, the domestic optical engine research platform is relatively backward, and the research institutions of domestic automobile manufacturers There is no such platform yet

Embodiment Construction

[0024] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0025] This embodiment relates to an extended piston of an optical engine, which mainly consists of a piston top window part 1, a piston extended part 2, two sets of piston compression rings 3, two Inconel alloy C-rings 4, bolts 5, a transparent window 6, Lining ring 7,9, oil control ring 8, piston pin hole 10, scraper ring 11, etc. are composed of parts. The piston top window part 1 and the piston extension part 2 of the extended piston are connected by bolts 5, the structure is simple, and the transparent window is easy to disassemble. Simultaneously, two groups of liner rings are arranged on the extended piston to ensure that the extended piston moves vertically along the cylinder liner 12 axes.

[0026] 1. The extended piston 13 is composed of two parts: the window part 1 at the top...

Abstract

The invention relates to an optical engine and a lengthened piston thereof. The optical engine mainly comprises a piston top window part (1), a lengthened piston part (2), two groups of piston compression rings (3), two inconel C-shaped rings (4), a bolt (5), a transparent window (6), bushing rings (7) and (9), an oil control ring (8), a piston pin hole (10), an oil scraper ring (11) and the like, wherein the piston top window part (1) of the lengthened piston is connected with the lengthened piston part (2) through the bolt (5). The optical engine has a simple structure, and the transparent window is easy to disassemble; and simultaneously, the two groups of backing rings are arranged on the lengthening piston, so that the lengthening piston makes vertical motion along the axis of a cylinder liner (12).

Description

technical field [0001] The invention relates to an optical engine and its extended piston. Background technique [0002] At present, the optical engine is mainly used to study the fuel injection in the engine cylinder, the spray stroke, etc. The lengthened piston is used, and a transparent window as large as possible is set on the top surface of the piston. The size of the window is determined according to the cylinder diameter. A window is arranged, and a reflecting mirror is arranged in the window. Through the transparent window set on the head and the reflector on the engine, images are taken to study the flow field, spray, combustion and mixture formation in the cylinder. In the working process of optical engines, especially combustible optical engines, the seal between the transparent window of the head and the piston and the lubrication between the piston and the cylinder wall are very important. However, the domestic optical engine research platform is relatively bac...
