point 1 is replaced by the following:

‘1.INTRODUCTION

This Appendix describes the procedure to determine gaseous emissions from on-vehicle on-road measurements using portable emissions measurement systems (hereinafter ‘PEMS’). The pollutant emissions to be measured from the exhaust of the engine include the following components: carbon monoxide, total hydrocarbons and nitrogen oxides for compression ignition engines and carbon monoxide, non-methane hydrocarbons, methane and nitrogen oxides for positive ignition engines. Additionally, carbon dioxide shall be measured to enable the calculation procedures described in Sections 4 and 5.

For engines fuelled with natural gas, the manufacturer, technical service or approval authority may choose to measure the total hydrocarbon (THC) emissions only instead of measuring the methane and non-methane hydrocarbon emissions. In that case, the emission limit for the total hydrocarbon emissions is the same as the one specified in Annex I to Regulation (EC) No 595/2009 for methane emissions. For the purposes of the calculation of the conformity factors pursuant to points 4.2.3 and 4.3.2, the applicable limit shall in that case be the methane emission limit only.

For engines fuelled with gases other than natural gas, the manufacturer, technical service or approval authority may choose to measure the total hydrocarbon (THC) emissions instead of measuring the non-methane hydrocarbon emissions. In that case, the emission limit for the total hydrocarbon emissions is the same as the one specified in Annex I to Regulation (EC) No 595/2009 for non-methane hydrocarbon emissions. For the purposes of the calculation of the conformity factors pursuant to points 4.2.3 and 4.3.2, the applicable limit shall in that case be the non-methane emission limit.’;

(b)

in point 2.2., the sentence ‘The parameters summarised in Table 1 shall be measured and recorded:’ is replaced by the following:

‘The parameters as specified in Table 1 shall be measured and recorded at a constant frequency of 1,0 Hz or higher. The original raw data shall be kept by the manufacturer and shall be made available, upon request, to the approval authority and the Commission.’;

(c)

the following point 2.2.1 is inserted:

‘2.2.1. Data reporting format

Emission values as well as any other relevant parameters shall be reported and exchanged as csv-formatted data file. Parameter values shall be separated by a comma, ASCII-Code #h2C. The decimal marker of numerical values shall be a point, ASCII-Code #h2E. Lines shall be terminated by carriage return, ASCII-Code #h0D. No thousands separators shall be used.’;

(d)

points 2.6.1 and 2.6.2 are replaced by the following:

‘2.6.1. Test start

Emissions sampling, measurement of the exhaust parameters and recording of the engine and ambient data shall commence prior to starting the engine. The coolant temperature shall not exceed 303 K (30 °C) at the beginning of the test. In case ambient temperature exceeds 303 K (30 °C) at the beginning of the test, the coolant temperature shall not exceed the ambient temperature by more than 2 °C. The data evaluation shall start after the coolant temperature has reached 343 K (70 °C) for the first time or after the coolant temperature is stabilised within +/– 2 K over a period of 5 minutes whichever comes first but no later than 15 minutes after engine start.

2.6.2. Test run

Emission sampling, measurement of the exhaust parameters and recording of the engine and ambient data shall continue throughout the normal in-use operation of the engine. The engine may be stopped and started, but emissions sampling shall continue throughout the entire test.

Periodic zero-checks of the PEMS gas analysers may be conducted every 2 hours and the results may be used to perform a zero drift correction. The data recorded during the checks shall be flagged and shall not be used for the emission calculations.

In case of interrupted GPS signal the GPS data may be calculated based on the ECU vehicle speed and a map, for a consecutive period of less than 60 s. If the cumulative loss of GPS signal exceeds 3 % of the total trip duration, the trip should be declared void.’;

(e)

point 3.2.1 is replaced by the following:

‘3.2.1. Analysers and EFM data

The consistency of the data (exhaust mass flow measured by the EFM and gas concentrations) shall be verified using a correlation between the measured fuel flow from the ECU and the fuel flow calculated using the formula in paragraph 8.4.1.7 of Annex 4 to UN/ECE Regulation No 49. A linear regression shall be performed for the measured and calculated fuel rate values. The method of least squares shall be used with the best fit equation having the form:

y = mx + b

where:

  • y is the calculated fuel flow [g/s]

  • m is the slope of the regression line

  • x is the measured fuel flow [g/s]

  • b is the y intercept of the regression line

The slope (m) and the coefficient of determination (r2) shall be calculated for each regression line. It is recommended to perform this analysis in the range from 15 % of the maximum value to the maximum value and at a frequency greater or equal to 1 Hz. For a test to be considered valid, the following two criteria shall be evaluated:

(f)

point 4.1 is replaced by the following:

‘4.1. Averaging window principle

The emissions shall be integrated using a moving averaging window method, based on the reference CO2 mass or the reference work. The principle of the calculation is as follows: The mass emissions are not calculated for the complete data set, but for sub-sets of the complete data set, the length of these sub-sets being determined so as to match the engine CO2 mass or work measured over the reference laboratory transient cycle. The moving average calculations are conducted with a time increment Δt equal to the data sampling period. These sub-sets used to average the emissions data are referred to as “averaging windows” in the following points.

Any invalidated data shall not be considered for the calculation of the work or CO2 mass and the emissions of the averaging window.

The following data shall be considered as not valid data:

(a)

zero drift check of the instruments;

(b)

the data outside the conditions specified in points 4.2 and 4.3 of Annex II.

The mass emissions (mg/window) shall be determined as described in paragraph 8.4.2.3 of Annex 4 to UN/ECE Regulation No 49.

Appendix 6 Drain and weigh procedure

1.The engine shall be filled with new oil. If a constant volume oil sump system (as described in ASTM standard D7156-09) is used, the oil pump shall be turned on while filling the engine. Enough oil charge shall be added to fill up both the engine and external sump.U.K.

2.The engine shall be started and operated over the desired test cycle (see points 2.2.15 and 2.4.4.8.3.1) for a minimum of 1 hour.U.K.

3.Once the cycle is complete, oil temperature shall be allowed to stabilise at a steady-state engine condition before shutting the engine down.U.K.

4.A clean, empty oil drain pan shall be weighed.U.K.

5.Any clean supplies that are to be used during the oil drain (e.g. rags) shall be weighed.U.K.

7.The drained oil shall be weighed.U.K.

8.The weight determined in accordance with step 7 shall be subtracted from the weight determined in accordance with step 4. The difference corresponds to the total weight of the oil removed from the engine and collected in the drain pan.U.K.

9.The oil shall be carefully returned to the engine.U.K.

10.The empty drain pan shall be weighted.U.K.

11.The weight determined in accordance with step 10 shall be subtracted from the weight determined in accordance with step 4. The result corresponds to the weight of the residual oil in the drain pan that was not returned to the engine.U.K.

12.Any dirty supplies which have previously been weighed pursuant to step 5 shall be weighed.U.K.

13.The weight determined in accordance with step 12 shall be subtracted from the weight determined in accordance with step 5. The result corresponds to the weight of the residual oil which remained on the dirty supplies that was not returned to the engine.U.K.

14.The residual oil weights calculated in accordance with steps 11 and 13 shall be subtracted from the total weight of the oil removed, calculated in accordance with step 8. The difference between those weights corresponds to the total weight of the oil returned to the engine.U.K.

15.The engine shall be operated under the desired test cycle(s) (see points 2.2.15 and 2.4.4.8.3.1).U.K.

16.Steps 3-8 shall be repeated.U.K.

17.The weight of the oil drained pursuant to step 16 shall be subtracted from the weight obtained in accordance with step 14. The difference between those weights corresponds to the total weight of the oil consumed.U.K.

18.The total weight of the oil consumed calculated pursuant to step 14 shall be divided by the duration, in hours, of the test cycles carried out in accordance with step 15. The result is the lubricant consumption rate.U.K.
