Modification of an ignition quality tester and its use in characterizing middle distillate fuels
The Ignition Quality Tester ( IQTTM ) is a constant volume combustion chamber based device which is used to determine the derived cetane number of diesel fuel oils when used in conjunction with ASTM D6890. During a test, the fuel sample is injected into heated, pressurised gas where it combusts. …

Ignition Quality Tester: an alternative for characterizing the combustion kinetics of low volatility fuels, The
… of this thesis is to demonstrate that the Ignition Quality Tester (IQT) can be used to validate the kinetic mechanisms of both high and low volatility fuels. Such validated mechanisms are an essential component for engine models used to improve efficiency and determine the impact of …

Raman Chemometric Method for Fuel Property Prediction
Multi-fuel compression-ignition engines for unmanned aircraft systems require real-time knowledge of fuel ignition quality and related properties. Conventional measurements of derived cetane number (DCN) and density are accurate yet slow, sample intensive, and confined to laboratory instruments. …
