All characterization data of DW fuel injectors is collected and calculated in-house. The process involves collecting and analyzing over 450 data points on 4 standardized fuel injectors representative of the specific injector part number being tested. All data is collected in-house via calibrated digital turbine flow meters and fully programmable injector drivers. Testing procedures are performed in accordance with SAE J1832. Our offsets are calculated via linear regression from 5 different pulse widths, 4 different voltages, and 4 different pressures. Data between the tested voltages and pressures is interpolated.
