Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing:

[0030] like figure 1 As shown, this embodiment relates to a method for enlarging the field of view of an optical engine. The method is realized by pressing the pressure plate 1, the straight gland 3 and the transparent observation window 4 on the extended piston 5 by bolts 2, and the straight gland 3 and the degree of compression of the transparent observation window 4 can ensure the sealing of the transparent observation window 4 on the extension piston 5, and the transparent material of the straight port gland 3 can expand the image field of view captured under the extension piston 5.

[0031] like figure 2 and image 3 As shown, eight bolt holes 6 are arranged circumferentially on the pressure plate 1 .

[0032] like Figure 4 As shown, the structure of the straight gland cavity 7 of the straight gland 3 is a straight port to simulate the structure of a straight por...

Abstract

The invention discloses a method for enlarging the field of view of an optical engine. The method is realized by pressing a pressing plate of a transparent quartz observation window of an extended piston and a pressing cover of a transparent material with bolts. The transparent material of the gland is made of plexiglass, and the material of the pressure plate is made of aluminum. The application of the transparent material gland can expand the internal field of view of the combustion chamber in the cylinder to the entire combustion chamber space. The transparent material gland can be replaced according to different combustion chamber structures, that is, it can be designed in the shape of a constricted mouth, a straight mouth and an open combustion chamber. The mechanism of spray impingement on the wall and the influence of different combustion chamber structures on spray development, mixing, combustion and emission are thoroughly studied to meet the needs of different optical tests.

Description

technical field [0001] The invention relates to a method for enlarging the field of view of an optical engine, which is realized by pressing a plexiglass cover and an aluminum pressing plate of a transparent quartz observation window of a lengthened piston with bolts. Background technique [0002] The optical engine is a visualization engine whose main purpose is to obtain in-cylinder mixing and Combustion information is instructive for engine combustion design and optimization. At present, many foreign engine research institutions have established optical engine visualization test platforms, which have played a role in promoting the development of engine structure design and combustion theory. Our country's research in this area is still in its infancy. [0003] The typical structure of the optical engine is to adopt the method of lengthening the piston. Most of the space under the piston is hollowed out to install a 45-degree reflector, so that the working process in the ...
