EQUATION 1 TO PARAGRAPH (H)(6)
Where:
mCO2FTP = CO2 emission mass in grams emitted over the FTP driving cycle.
dFTP = measured driving distance in miles.
WFTP = work performed over the FTP.
i = an indexing variable that represents a 1 Hz OBD time counter over the course of the FTP drive.
N = total number of measurements over the FTP duty cycle = 1874.
fn = engine speed for each point, i, starting from the start of the FTP drive at i = 1, collected from OBD PID $0C.
T = engine torque in N·m for each point, i, starting from i = 1. Calculate T by subtracting Friction Torque (PID $8E) from Indicated Torque (PID $62) (both PIDs are percentages) and then multiplying by the reference torque (PID $63). Set torque to zero if friction torque is greater than indicated torque.
[DELTA]t = 1/ frecord
frecord = the data recording frequency.
Example:
mCO2FTP = 10,961 g
N = 1874
f1 = 687.3 r/min = 71.97 rad/s
f2 = 689.7 r/min = 72.23 rad/s
T1 = 37.1 ft·lbf = 50.3 N·m
T2 = 37.2 ft·lbf = 50.4 N·m
frecord = 1 Hz
[DELTA]t = 1/1 = 1 s = 0.000277 hr
WFTP = 71.97 · 50.3 · 1.0 + 72.23 · 50.4 · 1.0 + ··· fn1874·T1874· [DELTA] t1874
WFTP = 53,958,852 W·s = 20.1 hp·hr
eCO2FTPFCL = 545.3 g/hp·hr
