Reduce Work by Cooling Fan Work

Calculate Particulate Mass

Data for full flow dilution system. GEDF is directly measured by the CVS equipment:

PTMass = Mf / Msam * Gedf * x / 1000

x = test length in hours (1 for stationary tests)
Value Description
Mf Is the particulate mass sampled over the cycle in milligrams.
Msam or msep Is the mass of diluted exhaust gas passing the particulate collector filters in kilograms.
Gedf or medf Is the mass of equivalent diluted exhaust gas in kg/h. If the mass is only given in kg/test it must be converted to kg/h.

NOx-Measurement wet

If this option is selected the dry/wet correction is not applied. If the option is not selected the correction factor as defined in ISO 16183, Formula 14 is applied to the NOx data channel.

Certification Test

If this option is selected, all data points for all specified channels must be valid. The length of the data may be 5 seconds shorter than the length specified in the law (Example: The WHTC length is 1800 s. The data for the WHTC must be at least 1795 s long. If the option is not selected, the following limits must be met:

  1. 50% of all values must be valid.
  2. The time length of an invalid section is limited to 10 seconds.
  3. Only 10% of all data points of a single channel may be invalid.

Turbocharged engine

Is used to calculate the engine test conditions fa. For a test to be recognized as valid, the parameter fa shall be such that: 0.96 < fa < 1.06.
Engine Data
The power, torque and speed information are used to calculate the validation statistics of the test cycle.

Data Channels

Definition of Weight Factors for Stationary Tests

For the stationary test, the weight factors and the test limits are saved in a text file.

../../_images/emission-configuration-en.png

To edit the file, choose Emission Evaluation=>Configuration and click on the Open button. The file will be opened in an editor. All modifications can be used as soon as the file is saved. The file can be saved on a network drive.

An example file can be found in the addin directory (Default file).

Example for a Weight Factor File:

; Weight Factors for Steady State Test Cycles.
;
; Comments start with a semi colon in the first column.
;
; The order of the modes must match the order in the data file. The elements
; must be separated by a colon.
;
;Limit-HC in g/kWh
;Limit-NOx in g/kWh
;Limit-CO in g/kWh
;Limit-PM in g/kWh

; LimitName: Euro III, Euro IV, Euro V specifies the correction factor calculation.
[EURO III]
CycleType = ESC
LimitName = Euro III
Limit-CO = 2.1
Limit-HC = 0.66
Limit-NOx = 5.0
Limit-PM = 0.1
Limit-Smoke = 0.8
Weight-Factor = 0.15; 0.08; 0.10; 0.10; 0.05; 0.05; 0.05; 0.09; 0.10; 0.08; 0.05; 0.05; 0.05

[EURO IV]
CycleType = ESC
LimitName = Euro IV
Limit-CO = 1.5
Limit-HC = 0.46
Limit-NOx = 3.5
Limit-PM = 0.02
Limit-Smoke = 0.5
Weight-Factor = 0.15; 0.08; 0.10; 0.10; 0.05; 0.05; 0.05; 0.09; 0.10; 0.08; 0.05; 0.05; 0.05

The limit name is enclosed in square brackets. Each definition must specify the limitations for CO, HC, NOx, PM in g/kWh. The Limit-Name is a text that will be displayed in the report. For the ESC cycle the element LimitName also specified the regulation that is used to calculate the correction factors: Possible values: Euro III, Euro IV or Euro V.

The weight factors are separated by a semi-colon. The number of elements must match the number of data points and the order in the data file.

Verification of the test run (Regression Analysis)

In order to validate a test run, a regression analysis between the reference and the actual speed, torque and power values is executed. The regression analysis can be preformed with 1Hz or with the measured frequency. If the option 1 Hz is selected, the data is interpolated to 1 Hz using a linear interpolation.

The time lag between the actual and reference speed, torque and power values is calculated so that the regression results are minimized.

For the NRTC Cycle the first 25 seconds and last 25 seconds are ignored in the regression analysis.

If the regulation expects full load demand or no load demand. The following values of the throttle position are used:

Full load demand: Throttle Position is > 95%

No load demand: Throttle Position is < 5%

Permitted point deletions from regression analysis: Only those points are deleted from the regression analysis if the difference between the reference and the feedback value is greater than a tolerance of 1% of the maximum value.

Speed reference values: If the reference speed if smaller than 50% of the idle speed it will be set to idle speed. See Regulation No. 49, Revision 5.

For the WHTC-Test, the torque values are deleted for the for minimum and maximum operator demand (criteria 3 and 4).

WHTC Point Deletions: For Minimum operator Demand (idle point)) a window of +-0.5% is used and for Torque a window for +- idle torque is used.

WHTC Test:

For the “Minimum operator demand” and “Maximum operator demand” (Regulation No. 49, Revision 5) either torque or speed points can be omitted. Only those points will be removed from the statistic which are not in a range of 1% around the 45° line. The tolerance is 1% of the maximum torque or the maximum speed.

In a first step all points which are outside the tolerance for torque will be removed. If not all omitted points are used, the remaining points will be applied for speed.

Loading the measured data

Negative values for the emission channels are set to 0.

If the relative humidity is measured in the intake manifold, the relative air pressure in the intake pipe should be specified.

Determination of Particle Numbers:

the value of Gedf of the particle measurement is used,

k = 1, calibration factor. It is expected that that this factor is
is applied internally within the particle number counter,

c_mean: average concentration of particles from the diluted exhaust gas
corrected to standard conditions (273,2 K and 101,33 kPa), particles per cubic
centimetre,

f = 1, mean particle concentration reduction factor.

ELR Test

European load response test

The “ELR test” is a test cycle of a sequence of load steps at 3 or 4 constant engine speeds. The smoke is determined by means of an opacimeter. For each load step the smoke peak is determined. Calculation of the final smoke value from the averaged data:

SV = (0.43 × SV_A) + (0.56 × SV_B) + (0.01 × SV_C)

The opacimeter should apply a Bessel filter to the smoke data as described in the regulation.

The data should be measured over time with a frequency of 20Hz or higher. Instead of transient data file, a file with 9 or 12 records with the results of each load step can be selected.

If a transient data file is selected, a second page with the smoke, speed and torque versus time curves is added to the result page.

Extracting the load steps for a transient data file

  1. The signal length must be greater than 270 seconds (9 steps a 30 seconds)

2. The throttle signal must be below 70% for 10% load and above 70% for 100 % load.

  1. The throttle signal must cross the 70% line at least 17 times.

4. The length of the 100 % load period has to be between 8 and 12 seconds long. The regulation expects between 9 and 11 seconds.

  1. The length of the 10% load period has to be between 18 and 22 seconds long.
  2. The data is only valid if at least 9 or 12 load steps are found.

Smoke Data Validation

As described in E/ECE/324/Rev.1/Add.48/Rev.5, Annex 4A - Appendix 1, Paragraph 3.4 Cycle validation is executed:

“The relative standard deviations of the mean smoke values at each test speed (SVA, SVB, SVC, as calculated in accordance with paragraph 7.3.3. of this appendix from the three successive load steps at each test speed) shall be lower than 15 per cent of the mean value, or 10 per cent of the limit value shown in table 1 of paragraph 5.2. of the Regulation, whichever is greater. If the difference is greater, the sequence shall be repeated until three successive load steps meet the validation criteria.”

and, if a 4th random test speed is measured:

“5.2.3.2.: The smoke value on the random test speed of the ELR shall not exceed the highest smoke value of the two adjacent test speeds by more than 20 per cent, or by more than 5 per cent of the limit value, whichever is greater.”

EPA 1065

The calculation can be executed with drift correction. If drift correction is enabled, the gas concentration for zero gas and span gas must be measured before and after the test according to regulation EPA § 1065.672 Drift correction . The values for the gas concentrations must be specified in the dialog box Drift Check Configuration:

../../_images/emission-driftcorrection-en.png

The result values will be corrected with the calculated drift correction.
