INJECTOR DYNAMIC CHARACTERISTICS TESTING APPARATUS FOR VISUALIZATION OF GAS FLOW AND METHOD FOR TESTING INJECTOR DYNAMIC CHARACTERISTICS USING THE SAME

摘要

The present invention relates to an apparatus for testing an injector dynamic characteristic for visualizing a gas flow, comprising: a gas supply unit including a first gas supply unit for supplying a first gas and a second gas supply unit for supplying a second gas; A vibrator for applying vibration to the first base body; An injector for receiving the first gas and the second gas to generate a mixed gas and injecting the mixed gas to the outside; An image unit for photographing the mixed gas to generate image information; An operation unit for calculating information about a dynamic characteristic of the injector based on the image information; And a heater unit which supplies heat energy to the first gas and the second gas so that a density difference between the outside air and the mixed gas is formed when the mixed gas is injected from the injector unit, A reflector which is arranged to face the light source unit with the injector unit interposed therebetween and reflects and reflects the light passing through the mixed gas body; And a camera unit for receiving the light and generating the image information. According to the present invention, in an injector test system in which gas and gas are introduced, it is possible to effectively visualize the mixed gas injected from the injector, thereby effectively analyzing the dynamic characteristics of the injector in which gas and gas are introduced There is an effect that can be.
