AFIDA

We are specialized in prototyping according to individual customer requirements.

The AFIDA (Advanced Fuel Ignition Delay Analyzer) enables the fully automated characterisation of the ignition behaviour of liquid substances. Under standard conditions (IP 617, EN 17155, ASTM D8183), the indicated cetane number (ICN) of substances can be measured in a wide range from ICN 35 to ICN 85. The measurement result correlates perfectly with the cetane number determined on the test engine according to ISO 5165.

The measuring principle of the indicated cetane number at the AFIDA differs fundamentally from that of other constant volume combustion chambers, as the indicated cetane number is calculated with the help of a device-specific multi-point 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 prototype construction, the cetane number standard units 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, the connection of a second combustion gas, an interface to exhaust gas analysis devices or conversion to gasoline operation.
