Indicated Cetane Number Analysis

AFIDA is a revolutionary development providing fully automated determination of the Indicated Cetane Number (ICN) of diesel and diesel related fuels using test method IP 617.
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 improved performance and consistency when compared with solenoid controlled injectors and pintle type nozzles.
The analyser provides very fast, efficient and calibrated ICN determinations, tests are fully automated via an integral 36 position carousel and auto sampler.
