Device construction

We are specialized in prototyping according to individual customer requirements.

The AFIDA (Advanced Fuel Ignition Delay Analyzer) allows the fully automated determination of the ignition ability of liquid fuels. Under standard conditions (IP 617, EN 17155), the indecated cetan numbers (ICZ) of substances can be measured in a wide range from ICZ 35 to ICZ 85. The measurement result correlates perfectly with the number of cet determined on the test motor in accordance with ISO 5165.


The measurement principle of the indicated cetane number on the AFIDA differs fundamentally from that of other constant volume combustion chamber apparatuses, as the indicated cetane number is calculated using a device-specific multipoint calibration curve. For this purpose, each AFIDA is calibrated with seven primary reference fuel mixtures consisting of n-hexadecane and 1-methylnaphthalene.

In the field of prototyping, the cetane number standard devices are extended by customer-specific requests. In addition to the activation of combustion chamber parameters on the software side, this can also include hardware additions such as sample heating or cooling, the connection of a second combustion gas, an interface to exhaust gas analyzers or the conversion to gasoline operation.
