Problems solved by technology

[0005] However, the projectile body of this device is a cylinder, and only a pair of observation holes shaped as through holes are provided. To have an annular boss, the processing requirements for the glass are relatively high, which increases the difficulty of processing and the cost is high; moreover, the device is press

Abstract

The invention provides a constant volume combustion bomb. The constant volume combustion bomb comprises a bomb body which is internally provided with a cavity serving as a combustion cavity and is in the shape of a cube. The bomb body has six working surfaces serving as main mounting surfaces and auxiliary mounting surfaces formed at eight corners. The main mounting surfaces and the auxiliary mounting surfaces are provided with main mounting holes and auxiliary mounting holes. The constant volume combustion bomb further comprises a main mounting base accommodated in two opposite main mounting holes, a glass mounting base accommodated in another two opposite main mounting holes, a magnetic coupling fan accommodated in the last two opposite main mounting holes and used for driving mixed gas in the combustion cavity of the bomb body rotationally to make the mixed gas form a vortex, and auxiliary mounting bases accommodated in the auxiliary mounting holes to measure the pressure and temperature in the combustion cavity of the bomb body. The invention also provides the corresponding combustion system. The device has a structure adaptive to the combustion conditions of an internal combustion engine, allows comprehensive observation of a combustion process and thus is suitable for premixed combustion heating type constant volume bomb spray combustion diagnosis experiments with various research requirements.

Description

technical field [0001] The invention relates to the technical field of internal combustion engine combustion, in particular to a premixed combustion heating type constant-volume incendiary bomb and a combustion device provided with the constant-volume incendiary bomb. technical background [0002] Improving the combustion process in the engine cylinder is an important aspect to reduce emissions and improve the performance of diesel engines. Because the actual process of jet atomization, diffusion, evaporation, combustion, and heat transfer of the engine is very complicated, and accompanied by cyclic changes, it is difficult to control the environmental conditions, and it is not easy to carry out observation research. Therefore, the combustion research of internal combustion engines is mostly carried out on visual simulation experimental devices. [0003] In order to study the effect of spray combustion in the cylinder of an internal combustion engine, a constant volume ince...
