Jet fuel researchers can depend on the IQT – Ignition Quality Tester, powered by CFR Engines Inc., to meet the requirements of the ASTM Fast Track OEM Qualification and Approval Process for New Aviation Turbine Fuels (D4054 A4). The IQT measures the ignition delay, i.e. the time elapsed in milli seconds (ms) between fuel injection and combustion. The testing process involves the injection of jet fuel into a heated, Constant Volume Combustion Chamber (commonly called a CVCC). The resulting ignition delay measurement is used to generate a Derived Cetane Number (DCN) that is used to certify to the DCN specification of the standard.
