AFIDA – Advanced Fuel Ignition Delay Analyzer – SA6000-0 Indicated Cetane Number AnalysisAFIDA is a revolutionary development providing you with a fully automated way of determining Indicated Cetane Number (ICN) of diesel and diesel related fuels. The AFIDA can analyse multiple samples in sequence and selects the samples using the 36-place autosampler. Only a small sample volume of 40 ml is required per test with a short analysis time of approximately 25 minutes. The analyser uses a Constant Volume Combustion Chamber (CVCC) and incorporates a unique and patented high pressure injection system that generates fine fuel droplets similar to modern common rail injectors in most diesel engines. An ultra robust temperature controlled piezo electric injector provides rapid switching and highly repeatable fuel metering, offering you improved performance and consistency when compared with solenoid controlled injectors and pintle type nozzles.

Safety:The AFIDA has multiple integral safety monitoring functions to ensure the system is running safely and accurately.The AFIDA also has safety functions in place to prevent the system from overheating in the event of a power failure. Standardisation:Industry stakeholders recognise the advantages of the AFIDA with CEN, ASTM and the Energy Institute forming new working groups to develop test methodology; IP 617 is already published as an approved test method.Inter-laboratory studies showed outstanding precision and excellent correlation when compared with samples with known Cetane Numbers. The coefficient of determination (R²) is 0.98. An investigation into carryover with 2-EHN Cetane Improver showed no effect.
