Instrument design

In order for DEED to fulfill the requirements of long-term repeatable, continuous operation, Dekati® ejector diluter was chosen to be the dilution device for both first and second dilution stage.

The selection was based on long experience from using Dekati® ejector diluters and profound knowledge on the operation of the diluter in different conditions.

In addition, the all-stainless steel construction with no moving parts provides the needed robustness for long-term problem-free operation.

The schematic of the Dekati® Engine Exhaust Diluter is presented below:
