Five windows for viewing columns of fire

One of the worlds most modern test facilities for diesel fuel injection systems was recently installed at the University of Erlangen-Nuremberg. The chair of Technical Thermodynamics of Prof. Dr. Alfred Leipertz is investigating active combustion sequences in the hope to increase the efficiency of modern combustion engines and reduce emission of pollutants to a minimum.

The fully automated optical test rig was set up in cooperation with the firm of ESYTEC, Energie- und Systemtechnik GmbH, Erlangen.

The new test rig makes it possible to set the parameters at the moment of injection in a modern diesel engine. This means that fuel can be injected at up to 2500 bar into an environment with a pressure of 100 bar at approximately 700°C.

The injection, carburetion and combustion processes can be viewed from various angles through as many as five windows, which are strong enough to withstand the high temperatures and a

force of approximately 40 metric tons. A feature of particular note is the flowthrough mode of the new installation, which enables a fuel injection to take place every second. Despite extreme operating conditions, the new test rig is far more compact than any previously used installation.
