Problems solved by technology

[0004] Some existing spray characteristic measurement systems and methods can only measure the macroscopic or microscopic characteristics of the spray in an open space, or can only measure the macroscopic shape of the spray in a constant volume combustion device, and cannot cooperate with advanced optical measuring instruments. Measurement of microscopic characteristics (including particle size distribution information and velocity distribution information of spray particles), let alone simultaneous measurement of spray macroscopic morphology and microscopic characteristics in a constant volume combustion device
Therefore, such systems and methods are far from meeting the requirements of the test
This limitation severely hinders the study of the broken atomization depth of fuel

Description

technical field [0001] The invention relates to the field of constant-volume combustion devices, and more specifically, relates to a system and method for synchronously measuring the macroscopic appearance and microscopic characteristics of a spray. Background technique [0002] In the field of internal combustion engines, the atomization process of fuel directly affects the combustion and emission performance, thereby contributing to the alleviation of energy and environmental problems. Therefore, for internal combustion engine researchers, it is necessary to obtain fuel spray characteristics (jet breakage length, spray cone angle, oil droplet size and velocity, etc.) and its relationship with surrounding environmental parameters (pressure, temperature, ambient gas type and density, etc.) , and then establish the kinetic mechanism of fuel atomization reaction, and finally provide basic data for engine spray simulation and optimization, which is the main purpose of fuel inje...
