The Eindhoven High Pressure Cell (known as EHPC or "spray bomb") is designed to create
realistic engine-like conditions. The study of Diesel sprays (dynamics, geometry, combustion, soot
formation...) in an environment of high pressure and high temperature is performed in the EHPC
through optical diagnostic including Mie-scattering and Schlieren. The experimental set up mainly
consists of a constant-volume combustion vessel with optical access, a high-pressure common rail
fuel injection system, a gas supply device and an optical imaging acquisition system. The gas
supply, the fuel injection and the acquisition system are controlled and operated by a computer.

The vessel is a cubic combustion chamber with a constant volume of 1,2957 dm3. Depending on window material, the cell is supposed to be able to undergo a maximum pressure of 350 bar, even if in practice pressures are limited to 130 bar for quartz windows and 300 bar for sapphire windows. The three large windows (on entrance, exit and on a side) are all of equal size (50 mm thickness and 100 mm diameter) and permit full access to the vessel for optical diagnostic requiring access.
