II. 3. Definitions

1019.04.23

Definitions (mass) §3.2.d.

PROPOSAL:3.2.d. "Test mass of the vehicle" means the sum of the actual mass of the vehicle, 25 kg and mass representative of the vehicle load.

1119.04.23

September drafting meeting: the first 3.2.d. in the gtr is adopted.

JPN: we thought it was decided like, 3.2.d.“Test mass of the vehicle” means the sum of the mass of the vehicle in running order and its actually fitted optional equipment plus 25 kg and the mass representative of the vehicle load;

WLTP GTR DRAFTING ISSUESTEXT OF GTR, DEFINITIONS, § 3.2.14. BMW #1

WLTP Drafting, BMW, 18.08.2015

Justification: "simulated" is only used in the context of simulating road load on a chassis dyno and refers to the total road load, the

vehicle is exposed to on a dyno (RR and drivetrain losses of the vehicle plus applied force by the chassis dyno). Definition unclear improve.

Change text:

"Simulated road load" means the road load applied to the vehicle on a chassis dynamometer and is the sum of the losses of the vehicle itself plus the applied force of the dynamometer .

September 2015 drafting meeting:Currently being discussed in the road load task force; still under review.

WLTP GTR DRAFTING ISSUESTEXT OF GTR, DEFINITIONS, §3.5.8. BMW #2


Justification: "Modes" that do not effect emissions should not be considered (e.g. "night mode" of dashboard).

Change 3.5.8.:

3.5.8. "Mode" means a distinct driver-selectable condition which affects emissions, or fuel or energy consumption.

September 2015 drafting meeting: Appears not to have been wrapped up.

Definitions, §3.3.10.Current GTR Text:3.3.10. "Energy storage system" means the part of the powertrain on board a vehicle that can store chemical, electrical or mechanical energy and which can be refilled or recharged externally and/or internally.

1419.04.23

September 2015 drafting meeting: To be discussed.

Definitions, §3.3.14.

GTR Text:3.3.14. "Hybrid electric vehicle" means a vehicle using at least one fuel consuming machine and one electric machine for the purpose of vehicle propulsion.

15

Proposal from W. Coleman:3.3.14. "Hybrid electric vehicle" means a hybrid vehicle where one of the energy converters is an electric machine.

19.04.23


Definitions, §3.3.xx.

GTR Text:3.3.xx. "Hydrogen fuel cell vehicle" means a vehicle powered by a fuel cell that converts chemical energy from hydrogen into electric energy, for propulsion of the vehicle.

1619.04.23


Task: Approval of the definition. (identical to the definitions in ECE-R 101 and ECE-R 83)

Definitions, §3.4.1.

1719.04.23

September 2015 drafting meeting: adopted.

Current GTR:3.4.1. "Manual transmission" means a transmission where gears are shifted by hand in conjunction with a manual disengagement of a clutch.Proposed definition (A. Feucht):3.4.1. "Manual transmission" means a transmission where gears can only be shifted by action of the driver.Reasoning: There are vehicles (smart, A2,…) where gears can only be shifted by action of the driver but where no manual disengagement of the clutch is necessary because the clutch is automated.Task: Approval of the proposed definition.

September 2015 drafting meeting: see comments from Japan on the next slide.

WLTP GTR DRAFTING ISSUESANNEX 2, §2.(H), GEARSHIFTING. BMW #6


September 2015 drafting meeting: Comments from Japan adopted.

JPN: Better to be in line with definition 3.7.1. (i.e. add “current regional regulation” to proposal, or delete “current regional regulation” from 3.7.1.)

3.7.1. "Rated engine power" (Prated) means maximum engine power in kW as per the certification procedure based on current regional regulation. In the absence of a definition, the rated engine power shall be declared by the manufacturer according to Regulation No. 85.

2419.04.23

Task: Clarification of the highlighted text.Within a period of 5 minutes, the vehicle, having the mass defined in the equation below, shall be able to pull away from standstill on an uphill gradient of at least 12 per cent in 2nd gear on five separate occasions, pulling away within 4 seconds on each occasion.

Gear selection, §2.(j)(e)September 2015 drafting meeting:Basically accepted but Rob Gardner to check the wording.

2519.04.23

Gear selection, §2.(j)(e)September 2015 drafting meeting:Adopt (8) but not (9). Correlate with GTR j.(5). Already in the GTR as a definition.

September 2015 drafting meeting: R. Cuelenaere to resend mails to these subjects. DC to incorporate accordingly.

Information: The Annex 4 Task Force is reviewing all of Annex 4 but it has been requested to examine at the request of DC paragraphs 4.2.1.7.3.; 4.3.1.3.2.; 4.3.1.3.4.; 4.3.2.6.6.; 4.5.5.1.; 8.1.3.2.1.; and 1.1., 1.2. and 2.2. of Annex 4, Appendix 1.

WLTP GTR DRAFTING ISSUESANNEX 4, §3.2. WIND TUNNEL CRITERIA. BMW #7


Delete text below 3.2.

3.2. Wind tunnel criteria

All parts of the GTR using the criterion, are describing very clear for what and how to use them (see below). The current sentence is even wrong, because now used for wind tunnel method as well.

September 2015 drafting meeting:Text below 3.2. deleted. Introductory sentence added. See gtr.

WLTP DRAFTING, ANNEX 4, §3.2.8.WIND TUNNEL CRITERIA, CP

Old text:Annex 4, 3.2.8.

New text:Annex 4, 3.2.8., "cp"

The absolute difference of the pressure coefficient, cp, over a distance 2 metres ahead and 2 metres behind the vehicle and at a height of the center of jet shall not deviate more than ± 1 per cent


Task: Text to the right yet to be approved.

September 2015 drafting meeting:Blue box approved.2 per cent in the equation replaced by 0.02. Reference to “per cent” in the text above it also replaced.

September 2015 drafting meeting: Adopted, GTR modified accordingly.

Annex 4, Road load, §7.2.1. Inertia mass setting (page 1 of 2)

19.04.23

September 2015 drafting meeting: Use version 6 as benchmark but 7.2.1. is still not complete. A. Feucht to make a concrete proposal.

The equivalent inertia mass of the chassis dynamometer shall be set to the test mass if a dual-axis chassis dynamometer is used. In the case that a single-axis chassis dynamometer is used where one axle is not accelerated by the vehicle, the equivalent inertia mass shall be increased either by the equivalent effective mass of the standing wheels or by 1.5 per cent of the sum of the mass in running order and 25kg.

31

Task: Section to be reviewed (During June drafting meeting:, C. Lueginger offered to review the section)

3219.04.23

The equivalent inertia mass of the chassis dynamometer shall be set to the test mass if a dual-axis chassis dynamometer is used. In the case that:

- a single-axis chassis dynamometer is used - a dual-axis chassis dynamometer where one axle is not

accelerated by the vehicle - a dual-axis chassis dynamometer where the two axles are

accelerated by the vehicle, but the axle with the drivetrain is completely disconnected with the second axle,

the equivalent inertia mass shall be increased either by the equivalent effective mass of the standing wheels or by 1.5 per cent of the sum of the mass in running order and 25kg.

Annex 4, Road load, §7.2.1. Inertia mass setting (page 2 of 2)

EXPERT PROPOSAL:June drafting meeting: approval of the text in yellow and red.C. Lueginger to review this section

Task: Section to be reviewed (During June drafting meeting, C. Lueginger offered to review the section)

WLTP DRAFTING, ANNEX 4, §7.2.1.ROTATIONAL MASSES

Adding 1.5 % not depending on the dyno directly, but on the situation, that one axle is not taken into account. So also on a two axle dyno driven with one axle only.

Proposal shall consider of any case, that 1.5% are added in the case one axle is not considered for inertia.

Old text:Annex 4

New text:Annex 4

7.2.1. Inertia mass setting

The equivalent inertia mass of the chassis dynamometer shall be set to the test mass if a dual-axis chassis dynamometer is used. In the case that:

(a) a single-axis chassis dynamometer is used;

(b) a dual-axis chassis dynamometer where only one axle is used for representing the inertia;

the equivalent inertia mass shall be increased either by the equivalent effective mass of the standing wheels or by 1.5 per cent of the sum of the mass in running order and 25 kilograms. If the chassis dynamometer is not capable to meet the inertia setting exactly, the next higher inertia setting shall be applied with a maximum increase of 10 kg.


June drafting: Has to be redone. Place on hold.July: still in progress.

September 2015 drafting meeting:

WLTP GTR DRAFTING ISSUESANNEX 4, §8. CHASSIS DYNO SETTING. BMW #10


Change 8.1.

8.1. Chassis dynamometer setting by the coastdown method

This method is applicable when f0, f1, f2 values (N, N/(km/h), N/(km/h)²) have been determined.

"Normal" chassis dyno setting to be applied not only in the case of coast down testing, but also for wind tunnel testing, calculated values, extrapolation method or torque meter method, if f0, f1, f2 values have been determined.

The text should reflect, that this method is applicable, if "normal" road load values are available.

September 2015 drafting meeting: proposed change adopted. Text incorporated in GTR as proposal.

WLTP GTR DRAFTING ISSUESANNEX 4, §8.2.4. TORQUE METER METHOD. BMW #8


New first paragraph in 8.2.4.

8.2.4. If the vehicle does not coast down in a repeatable manner and a coast down mode according to paragraph 4.2.1.7.5. is not feasible, the determination as well as the use of f0, f1, f2 values may be omitted and paragraph 8.2.4.1. applies. In any other case the procedure described in paragraphs 8.2.4.2. to 8.2.4.3. shall be performed.

8.2.4.1.

f0' = c0 / r

f1' = c1 / r

f2' = c2 / r

where:

c0, c1, c2 are the running resistance coefficients determined in paragraph 4.4.4. of this Annex, Nm, Nm/(km/h), Nm/(km/h)²;

r is the dynamic tyre radius of the vehicle with which the running resistance was determined, m.

The determined f0', f1', f2' values shall not be used for a chassis dynamometer setting or any emission or range testing. They shall be used only in the following cases:

(a) determination of downscaling, paragraph 8. of Annex 1;

(b) determination of gearshift points, Annex 2;

(c) interpolation of CO2 and fuel consumption, paragraph 3.2.3 of Annex 7;

(d) calculation of results of electrified vehicles, paragraphs TBD.

Move that paragraph to 8.2.4.2.:

Once the chassis dynamometer has been set within the specified tolerances, a vehicle coastdown shall be performed on the chassis dynamometer as outlined in paragraph 4.3.1.3. The coastdown times shall be recorded.

Shift following paragraphs by one: 8.2.4.1. .2 and .2 .3. Downscaling, gearshifting and interpolation method need f0, f1, f2 values, which are normally available also from the torque meter method.

In the case, that the vehicle cannot be coasted down under any reasonable condition, we need a fallback solution. The proposed formula will be a worst case approach for (a) and (b) and is equivalent to "normal" f0f1f2 for (c) and (d).

September 2015 drafting meeting: Adopted, text incorporated into the GTR as proposal.

WLTP GTR DRAFTING ISSUESANNEX 4, APPENDIX 1, §2.2. AND 2.3. TORQUE METER METHOD. BMW #9


Move these two formulas to paragraph 8.2.3.2. Explain the formulas better (what are the variables). It is intended to compare the simulated road load of the dyno with the

target road load on the basis of a force. Having done that, Appendix 1 appears to be not used any more and can be deleted.

Paragraphs 2.2. and 2.3. of Appendix 1 of Annex 4: 8.2.3.2. The simulated road load, Fsj, and the target road load, Fs, shall be calculated according to the equations below, at each reference speed, vj:

<< formulas from Appendix 1 >>

The simulated road load shall be within a tolerance of ±10 N from the target road load, in the specified speed ranges, at each reference speed vj.

If the tolerance at any reference speed does not satisfy the criterion of the method described in this paragraph, paragraph 8.2.3.3. below shall be used to adjust the chassis dynamometer load setting.

September 2015 drafting meeting: Text incorporated into the GTR as a proposal.

Annex 5Test equipment and

calibrations

3719.04.23

3819.04.23

September 2015 drafting meeting: No equation necessary. Adopted.

Annex 5, Table A5/1 and §4.2.2.2. Linear response of an analytical balance

It was agreed to refer to the intercept as a0 and the slope as a1, but is an equation required in the form of y = mx +b, i.e.

measured mass = a0 + a1 × actual mass

Is the number of points also not necessary?

Comment ADAM: In the paragraph above is written that „at least 4 equally-spaced reference weights shall be tested“. There is also mentioned that linear regression is applied. Therefore, an equation is not required. These modifications are approved by B. Giechaskiel (JRC).

3919.04.23

September 2015 drafting meeting: Remains as "is"

Annex 5, §7.1.1. Laser Diode Spectrometer (LDS) or Quantum Cascade Laser (QCL)

Comment ADAM: no LH – Agreed : the absorption line is chosen

Annex 5, §7.2.1.2. Sampling for N20

4019/04/23 4019.04.23

September 2015 drafting meeting: remains open until task force meeting on September 16.

Task: Clarification of 7.2.1.2. is required. Possible interpretation on the next slide.

Page 1 of 2

Comment ADAM: I try to clarify it. For each WLTC-phase one exhaust bag has to be filled -> 4 bags.For each WLTC-phase one dilution air bag has to be filled -> 4 bags; in total 8 bagsAlternatively, it is sufficient to use the dilution air bag from WLTC_phase1 -> 1 bag; in total 5 bagsor one dilution air bag sampled over the whole WLTC -> 1 bag; in total 5 bags

Annex 5, §7.2.1.2. Sampling for N20

4119/04/23 41

September 2015 drafting meeting:

Does this mean, that only 5 bags are required? Or, are 9 bags required?Why is this any different from the number of bags required for all other compounds? Possible rewording as Dubuc/Coleman understand the paragraph:

During each phase of the test, a gas sample shall be taken for analysis from the corresponding diluted exhaust bag. Additionally, a gas sample shall be taken from one of the following sources: 1. The dilution air bag for each phase, or2. From the dilution air bag of phase 1 only, or3. From a single composite dilution air bag

Page 2 of 2

Comment ADAM: see previous slide

LH : this is to reduce the amount of time spent for the GC-MS and is similar to that applied for impinger and cartridge. For good practice, I think it should be individual phase bags for dilution air or 1 bag taken over the entire test ? Though in reality, the background N2O should be very stable given its sources in the atmosphere ?

4219.04.23

September 2015 drafting meeting: adopted. Unit is m³.

Annex 5, §7.1.2.5. NH3 measurement

Is the unit in Flow_lost_max m³ or smaller units, such as litres, which may account for the 0.005 in the equation?

Comment ADAM: the unit is the same as for Vmix, m3.

LH : the maximum lost amount of exhaust gas is 0.5% of the total exhaust volume per phase as calculated from Vmix and the DF.The result is in m3/phase

(this test is still from the calculations from MoerschI presume that he used m3 to be keep same units of the dilution tunnel. Leave it as it is)

Annex 5, §7.3.1.7.1. Sampling for Ethanol

4319/04/23 4319.04.23

September 2015 drafting meeting: Will be rewritten by Cova task force.

Task: What happens if you are above the LoD?Also, for how many weeks, i.e. how long?

7.3.1.7.1. A nitrogen or air blank run shall be performed before running the calibration standard.

The ethanol concentration from the blank analysis must be below the LoD before the analysis may proceed. A weekly blank run shall provide a check on contamination of the complete system.

Comment ADAM: delete the sentence „ The ethanol… proceed“; a weekly blank run is necessary as long as the Ethanol analysis is carried out.

LH : A blank sampling run should have been taken within one week of the test ?

Annex 5, §7.3.1.9. Sampling for Ethanol

4419/04/23 4419.04.23

September 2015 drafting meeting: Adopted.

Task: Propose to change the title to :Calculations for GC from impingers and from diluted gas.Agreed?

Comment ADAM/all: agreed

Annex 5, §7.3.1.9. Sampling for Ethanol

4519/04/23 4519.04.23

September 2015 drafting meeting: adopted. Text to be received from Cova.

Task: 1. There is no 7.3.1.8. Should 7.3.1.9. become 7.3.1.8.?2. Can it be confirmed that 7.3.1.9. is a title?3. If so, can the titles in 7.3.1.10. and 7.3.1.11. be eliminated but the text "The limits…" and "Interference and…" be retained?

Comment ADAM:1. yes2. I think that should be deleted from there3. no

Annex 5, §7.4.1.4.2.1. Analysis for formaldehyde and acetaldehyde

4619/04/23 4619.04.23

September 2015 drafting meeting: Clarified. Filter paper must not be defined.

Task: Should the grade of filter paper be clarified? Comment ADAM: No. The last sentence can be deleted as is seems to be a copy/paste error. Acrolein is not a target compound

Annex 6, Appendix 2, Test procedure for electric power supply system monitoring

49

EXPERT PROPOSAL: 29.07.2014: Dr. Ligterink (TNO) and his colleague, Gerrit Kadijk, highlights inconsistencies within the GTR concerning units used in Annex 6, Appendix 2 (Test procedure for electric power supply system monitoring). The problem is whether (a) kW.h, joules or megajoules should be used in equations, and, (b), whether kW.h, joules or megajoiules should be used in the Willans factors, and (c) whether the equations are all correct. This applies also to Annex 7 (Calculations) and to Annex 8 (Evs).19.04.23

September: For electric energy, use kWh in Annex 8 and in Annex 6 App. 2.Conclusion: Annex 8 task force agenda? Niikuni-san to add this to Sept. 11 EV audio/web.Drafting Co.: contact UN ECE regarding the use of SI units.Comment: Should remain flexible even if UN ECE says that joules/MJ should be used, i.e. use kWh where appropriate.

WLTP GTR DRAFTING ISSUESANNEX 6, APPENDIX 2, §1. RCB CORRECTION. BMW #12


Is it clear enough, that if the vehicle has more than one battery:- all batteries are measured; YES- the threshold refers to the sum;- the correction is calculated using the sum of all Delta-RCBs of all batteries?

If not, whole Appendix 2 should be checked, as well as references in Annex 6 test.

Is the definition of battery / REESS clear? Is plus/minus energy in/out clear?

Current text:

Annex 6, Appendix 2

September 2015 drafting meeting: follow progress of Annex 8, App. 2 and match this appendix accordingly.

WLTP GTR DRAFTING ISSUESANNEX 6, APPENDIX 2, §2.1.1. RCB CORRECTION, MEASUREMENT TOLERANCE. BMW #11


Change text regarding tolerance in:

2.1.1. The battery current shall be measured during the tests using a clamp-on or closed type current transducer. The current transducer (i.e. a current sensor without data acquisition equipment) shall have a minimum accuracy of 0.1 per cent of full scale, and the full scale shall be selected within the maximum electric load and the maximum load + 50%.

There are two solutions: (1) Exclude current of starting the engine:

- small energy error;- measurement accuracy can be maintained;- risk of wrong application (which wire to measure?).

(2) Increase tolerance;no error in balanced energy;slightly lower accuracy;no risk of wrong application.

Favourite is option (2), which is reflected in the text.

Example average current, lower

average current, higher peak current

current [A] 5 15 >200

tolerance [A]to measured value

0.025 0.075 1.000

tolerance [A]to full scale of 200

0.2 0.2 0.2

Electric current cannot be measured with that accuracy, because:- taking an accurate instrument, it will be magnetized and therefore will have an offset with the first engine start (too high currents);- taking an instrument for high currents, cannot be that accurate.

Tolerance on the measured value is not a technical correct tolerance, only full scale tolerance is valid (while limiting the full scale).

September 2015 drafting meeting: not a drafting issue. Small group to analyse these proposals.

WLTP DRAFTING, ANNEX 6, APPENDIX 2, 1. GENERALBATTERY SOC CORRECTION

Is it clear enough, that if the vehicle has more than one battery:- all batteries are measured;- the threshold refers to the sum;- the correction is applied to the sum of all Delta-RCBs of all batteries?
