Title: 1.8T KRKTE and TVUB for SIEMENS DEKA EV14 FI11354?
Post by: Rocky on December 16, 2015, 05:06:05 AM
1.8T Engine:

From my calculations:

siemens deka FI11354
Static Flow Rate @ 43.5PSI (300kPa): 46.5 lb/hr = 5.86g/s = 351g/min = 478cc/min (+/-3%)
Static Flow Rate @ 58.0PSI (400kPa): 53.7 lb/hr = 6.77g/s = 552cc/min (+/-3%)

KRKTE = 50.2624  Vhzyl  Qstat

Vhzyl = Displacement/Cylinders = 1.781/4 = 0.44525

Qstat = injector value @ operating pressure

Conversion given n-heptane (the testing solution for injectors valued at 0.684g/cc Density)

FPR:
3bar@470cc/min -> 0,063759
4bar@552cc/min -> 0,055094

what about TVUB.. there is no FI11354 on specsheets:

Stop using the n-heptane constant 0,684, use casoline 0,749...u will get more accurate results.
