Application: Automotive Field

・ The failure behavior of automotive body materials
・ The combustion process in engines
・ The injection process in fuel injection equipment

In order to develop high-output, high-efficiency automobile engines, detailed observations and analyses of the structural components of the engine are required. This includes the process of fuel injection by fuel injection equipment (injectors), and the process of fuel ignition by spark plugs.
In addition, the development of automobile bodies utilizing new materials such as lightweight and very strong carbon fiber reinforced plastics (CFRP) is actively being pursued. However, in developing such new materials, it is necessary to observe and analyze the deformation and failure behavior of materials when they undergo an impact.
In recent years, the deformation behavior of materials recorded using high-speed cameras has been analyzed using image analysis software. Dynamic analyses of the 2D or 3D strain distributions in the material are also performed.
In addition, high-speed cameras are used to observe the engine combustion process and the behavior of airbags.

Observation and Analysis of Engine Components

Discharge of spark plug or fuel injection from the nozzle can be observed in part alone or by visualization engine and analyzed in detail.

Observation and Analysis of Engine Components

Fuel Injection Nozzle (Injector) for an Automobile Engine

Liquid fuel is injected from the engine's fuel injection nozzle. Analysis of the process of atomization, by which the fuel is changed into fine particles of uniform size, is indispensable for the development of high-power, high-efficiency engines. The images illustrate how the liquid fuel injected at high speed from the pores in the nozzle tip forms a cone-shaped film, which then changes into droplets.

Atomization Process of Fuels

The liquid fuel injected from the nozzle is captured. The liquid film turns into the droplets with increasing distance from the nozzle.

Spark Plugs

The recorded image shows the spark discharge occurring between the electrodes of the spark plug. It is evident that the spark is bent significantly by the impact of the fuel injected from the left side to the right side of the image.

High-Speed Tensile Test of Carbon Fiber Reinforced Plastics (CFRP)

The image illustrates the breakage of the CFRP by the high-speed tensile testing machine. The CFRP fractures instantaneously at the limit load, so a recording speed of 10 million frames/second is required to capture the fracturing process in detail.
