AFIDA – Indicated Cetane Number Analyser - SA6000-0

Details

Direct correlation to ASTM D613 (ISO 5165) engine tests:
The traditional Cetane Engine methods establish an ignition delay period for the test fuel which is referenced to a primary reference fuel scale.

Existing Constant Volume Combustion Chamber (CVCC) technology provides a Derived Cetane Number (DCN) result based on a historical averaged correlation equation applied to the ignition delay of the fuel sample.

The new generation AFIDA technology is a significant step forward as it uses the same Primary Reference Fuels as specified in the Cetane Engine method to provide a calibrated cetane number measurement.

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.
