C.5.6.6 compression ignition engine THC determination
To determine the mass emissions of compression-ignition engines THC, according to the following formula to calculate the average THC concentration:
THC dtC - heated FID curve recorded during the test points (t2-t1) inside;
Ce - THC concentration of the diluted exhaust gas measured, ppmC;
Ci - in all relevant formulas, Ci directly replace CTHC.
C.5.6.7 determine particulate matter
Particulate matter emissions calculated by the following formula Mp (g/km):
When the particulate sampling the sample gas to the dilution tunnel outside row:
When the particulate sampling within the sample gas dilution tunnel back row:
Where:
Vmix - Under standard conditions, the diluted exhaust gas volume (see C.5.6.1), m3;
Vep - the standard state flow through the particulate filters exhaust volume, m3;
Pe - particulate mass collected by filters, g;
d - a distance equivalent to the actual operation cycle, km;
Mp - particulate matter emissions, g/km.
If the particulate background level of the dilution system is determined in accordance with C.5.2.4, the particulate mass may be background corrected.
If dilution system particulate matter concentration in background correction shall be conducted in accordance with the provisions of C.5.2.4. In this case, the quality of material particles (g/km) should
Calculated as follows:
When the particulate sampling the sample gas to the dilution tunnel outside row:
When the particulate sampling within the sample gas dilution tunnel back row:
Where:
Vap - the volume of gas flowing through the background particulate filter (standard state), m3;
Pa - Background mass filter to collect particulate matter, g;
Df - determined according to the dilution factor C.5.6.4.
If background correction after the result is negative, the measurement of particle mass should be considered as 0 g/km.
C.5.6.8 determine the number of particles
The number of particles is calculated as follows:
fCkVN rs
310. =
Where:
N - the number of particles emitted to the number of particles/km representation;
V - volume of the diluted exhaust gas, L/test and corrected to standard conditions (273.2K and 101.33kPa);
k - correction factor, when no particle counter calibration, k is the particle counter calibration measurements to the reference level of the instrument
Factor; if the particle counter has been calibrated, the k value takes 1;
sC - particle concentration subsequently amended diluted exhaust gas, a complete emission test cycle average number of particles/cm3 represents; if the particle count
Volume average concentration result is obtained, the concentration should be revised (C) is not a standard condition (273.2K, 101.33kPa) under
N to the standard state ({sC);
rf - average particle concentration of the test dilution setting the volatile particle removal reduction factor;
d - operation cycle mileage, km.
C calculated by the formula:
