Observation of Fuel Injection

Visualization of high-speed phenomena is attracting attention in various industrial fields. In the face of environmental problems and seeking to save energy, the automobile industry is conducting significant research into fuel injection in engines.

Observations of fuel injection are required to determine how the fuel disperses after injection and how the concentration distribution fluctuates. In addition, research and development into fuel injection involves changing the shape of the injection nozzle and discharge pressure to derive the optimal conditions. High-speed imaging is essential for this research due to the high speed of the injected fuel.

Images of fuel injected from a nozzle were captured by a HyperVision HPV-2 High-Speed Video Camera. The images were captured at 200,000 frames per second.
Data extracted at 45 µs intervals from the start of injection clearly reveal the shape of the spreading fuel and the changes in the concentration distribution.

The Shimadzu HyperVision HPV-2 High-Speed Video Camera offers ultra-high-speed imaging at speeds up to one-million frames per second. It achieves 81 k pixel high resolution, regardless of the imaging rate. This is the optimal video camera for capturing the shape of spreading fuel and concentration distribution fluctuations after the fuel is injected at an extremely high speed.

High-Speed Video Camera

Takes 100 consecutive images at up to one million frames per second. Maintains a constant 312 x 260 pixel resolution up to the maximum frame rate. A single PC can control synchronous imaging with a maximum of four cameras to observe the phenomena from multiple viewpoints.
