Embodiment Construction

[0022] 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.

[0023] In the preferred embodiment, parts such as the original engine cylinder head, cylinder block, crankcase system and connecting rod remain unchanged, the piston is lengthened, and the head of the extended piston is equipped with transparent quartz glass, and the side of the extended piston has a window, and the window The height is greater than the stroke of the engine (to prevent the piston from bumping into the reflector when moving up and down), the window is equipped with a reflector, and a transparent quartz glass cylinder liner is added between the cylinder block and the cylinder head. Through the reflector at the bottom of the piston and the transparent cylinder liner, it can be detected The flow field, spray and the formation of mixed gas in the cylinder; the inner diameter o...

Abstract

The invention relates to an optical engine which comprises a cylinder cover, an original cylinder casing and a piston; a transparent quartz glass cylinder casing is arranged between the cylinder cover and the original cylinder casing; the piston is an extended piston; the top of the extended piston is provided with a round window; transparent quartz glass is arranged in the round window; the length of the transparent quartz glass cylinder casing is more than the sum of the stroke of the engine and the distance between a ring at the bottommost of the piston and the top surface of the piston; and an engine cylinder body, the original cylinder casing, the cylinder cover and the transparent quartz glass cylinder casing are fixedly connected by bolts.

Description

technical field [0001] The invention relates to an engine, in particular to an optical engine. Background technique [0002] At present, the use of optical engines has become one of the directions for developing engines. The optical engine combustion system uses visualization, combined with advanced technologies such as lasers and high-speed cameras, to detect in-cylinder spray, flow field and combustion process, thus providing good conditions for combustion research. Various large automobile and engine research institutions in the world, such as Austrian AVL, FEV, and some combustion research institutions, have established optical engine research platforms. Optical engine platforms have become an important support for the development of engines, especially in-cylinder direct injection engines. In the prior art, the optical engine mainly uses a transparent window installed on the top of the piston, or a part of the cylinder liner is transparent, combined with various advanc...
