K.1. Introduction

This annex sets out the requirements for vehicles that rely on the use of a reagent for the after-treatment system in order to reduce emissions.

K.2. Reagent indication

The vehicle shall include a specific indicator on the dashboard that informs the driver of low levels of reagent in the reagent storage tank and of when the reagent tank becomes empty.

K.3. Driver warning system

K.3.1. The vehicle shall include a warning system consisting of visual alarms that informs the driver when the reagent level is low, that the tank soon needs to be refilled, or the reagent is not of a quality specified by the manufacturer. The warning system may also include an audible component to alert the driver.

K.3.2. The warning system shall escalate in intensity as the reagent approaches empty. It shall culminate in a driver notification that can not be easily defeated or ignored. It shall not be possible to turn off the system until the reagent has been replenished.

K.3.3. The visual warning shall display a message indicating a low level of reagent. The warning shall not be the same as the warning used for the purposes of OBD or other engine maintenance. The warning shall be sufficiently clear for the driver to understand that the reagent level is low (e.g. "urea level low", "AdBlue level low", or "reagent low").

K.3.4. The warning system does not initially need to be continuously activated, however the warning shall escalate so that it becomes continuous as the level of the reagent approaches the point where the driver inducement system in paragraph K.8 comes into effect. An explicit warning shall be displayed (e.g. "fill up urea"', "fill up AdBlue", or "fill up reagent").  The continuous warning system may be temporarily interrupted by other warning signals providing important safety related messages.

...

...

...

Please sign up or sign in to your TVPL Pro Membership to see English documents.



K.4. Identification of incorrect reagent (as recommended by the manufacturer)

K.4.1. The vehicle shall include a means of determining that a reagent corresponding to the characteristics declared by the manufacturer and recorded in Annex A to this Regulation is present on the vehicle.

K.4.2. If the reagent in the storage tank does not correspond to the minimum requirements declared by the manufacturer the driver warning system in paragraph 3. shall be activated and shall display a message indicating an appropriate warning (e.g. "incorrect urea detected", "incorrect AdBlue detected", or "incorrect reagent detected"). If the reagent quality is not rectified within 50 km of the activation of the warning system then the driver inducement requirements of paragraph K.8 shall apply.

K.5. Reagent consumption monitoring

K.5.1. The vehicle shall include a means of determining reagent consumption and providing off-board access to consumption information.

K.5.2. Average reagent consumption and average demanded reagent consumption by the engine system shall be available via the serial port of the standard diagnostic connector. Data shall be available over the previous complete 2,400 km period of vehicle operation.

K.5.3. In order to monitor reagent consumption, at least the following parameters within the vehicle shall be monitored:

K.5.3.1. The level of reagent in the on-vehicle storage tank;

K.5.3.2. The flow of reagent or injection of reagent as close as technically possible to the point of injection into an exhaust after-treatment system.

...

...

...

Please sign up or sign in to your TVPL Pro Membership to see English documents.



K.5.5. In the case of interruption in reagent dosing activity the driver warning system as referred to in paragraph K.3 shall be activated, which shall display a message indicating an appropriate warning. This activation shall not be required where the interruption is demanded by the engine ECU because the vehicle operating conditions are such that the vehicle's emission performance does not require reagent dosing, provided that the manufacturer has clearly informed the approval authority when such operating conditions apply.

K.6. Monitoring NOx emissions

K.6.1. As an alternative to the monitoring requirements in paragraphs K.4 and K.5, manufacturers may use exhaust gas sensors directly to sense excess NOx levels in the exhaust.

K.6.2. The manufacturer shall demonstrate that use of these sensors, and any other sensors on the vehicle, results in the activation of the driver warning system as referred to in paragraph 3., the display of a message indicating an appropriate warning (e.g. "emissions too high – check urea", "emissions too high – check AdBlue", "emissions too high – check reagent"), and the driver inducement system as referred to in paragraph 8.3., when the situations referred to in paragraph 4.2., 5.4. or 5.5. occur.

K.7. Storage of failure information (as recommended by the manufacturer or importer)

K.7.1. Where reference is made to this paragraph, a non-erasable Parameter Identifier (PID) shall be stored identifying the reason for the inducement system activation. The vehicle shall retain a record of the PID and the distance travelled by the vehicle during the inducement system activation for at least 800 days or 30,000 km of vehicle operation The PID shall be made available via the serial port of a standard diagnostic connector upon request of a generic scan tool.

K.7.2. Malfunctions in the reagent dosing system attributed to technical failures (e.g. mechanical or electrical faults) shall also be subject to the OBD requirements in Annex K to TCVN 6785:2015.

K.8. Driver inducement system (as recommended by the manufacturer or importer)

K.8.1. The vehicle shall include a driver inducement system to ensure that the vehicle operates with a functioning emissions control system at all times. The inducement system shall be designed so as to ensure that the vehicle can not operate with an empty reagent tank.

...

...

...

Please sign up or sign in to your TVPL Pro Membership to see English documents.



K.8.3. The manufacturer shall select which type of inducement system to install. The options for a system are described in sub-paragraphs K.8.3.1., 8.3.2., 8.3.3. and 8.3.5 of this Annex.

K.8.3.1. A "no engine restart after countdown" approach allows a countdown of restarts or distance remaining once the inducement system activates. Engine starts initiated by the vehicle control system, such as start-stop systems, are not included in this countdown. Engine restarts shall be prevented immediately in any of the following cases, whichever occurs earlier.

K.8.3.1.1. The reagent tank becomes empty;

K.8.3.1.2. A distance equivalent to a complete tank of fuel has been exceeded since the activation of the inducement system.

K.8.3.2. A "no start after refuelling" system results in a vehicle being unable to start after re-fuelling if the inducement system has activated.

K.8.3.3. A "fuel-lockout" approach prevents the vehicle from being refuelled by locking the fuel filler system after the inducement system activates. The lockout system shall be robust to prevent it being tampered with.

K.8.3.4. A "performance restriction" approach restricts the speed of the vehicle after the inducement system activates. The level of speed limitation shall be noticeable to the driver and significantly reduce the maximum speed of the vehicle. Such limitation shall enter into operation gradually or after an engine start. Shortly before engine restarts are prevented, the speed of the vehicle shall not exceed 50 km/h. Engine restarts shall be prevented immediately after the reagent tank becomes empty or a distance equivalent to a complete tank of fuel has been exceeded since the activation of inducement system, whichever occurs earlier.

K.8.4. Once the inducement system has fully activated and disabled the vehicle, the inducement system shall only be deactivated if the quantity of reagent added to the vehicle is equivalent to 2,400 km average driving range, or the failures specified in paragraphs K.4, K.5, or K.6 have been rectified. After a repair has been carried out to correct a fault where the OBD system has been triggered under sub-paragraph K.7.2., the inducement system may be reinitialised via the OBD serial port (e.g. by a generic scan tool) to enable the vehicle to be restarted for self-diagnosis purposes. The vehicle shall operate for a maximum of 50 km to enable the success of the repair to be validated. The inducement system shall be fully reactivated if the fault persists after this validation.

K.8.5. The driver warning system referred to in paragraph K.3 shall display a message indicating clearly:

...

L.6.3.2. Operation on track or road

When the durability test is completed on track or road, the vehicle's reference mass will be at least equal to that retained for tests conducted on a chassis dynamometer.

L.7. Measuring emissions of pollutants

At the start of the test (0 km), and every 10,000 km (±400 km) or more frequently, at regular intervals until having covered 160,000 km, exhaust emissions are measured in accordance with the Type I Test as defined in sub-paragraph 5.3.1. of TCVN 6785:2015.

In the case of vehicles equipped with periodically regenerating systems as defined in paragraph 4.58. Part I of this Regulation, it shall be checked that the vehicle is not approaching a regeneration period. If this is the case, the vehicle must be driven until the end of the regeneration. If a regeneration occurs during the emissions measurement, a new test (including preconditioning) shall be performed, and the first result not taken into account.

All exhaust emissions results shall be plotted as a function of the running distance on the system rounded to the nearest kilometre and the best fit straight line fitted by the method of least squares shall be drawn through all these data points. This calculation shall not take into account the test results at 0 km.

Please sign up or sign in to your TVPL Pro Membership to see English documents.



The data are still acceptable when a best fit straight line crosses an applicable limit with a negative slope (the 6,400 km interpolated point is higher than the 160,000 km interpolated point) but the 160,000 km actual data point is below the limit.

A multiplicative exhaust emission deterioration factor shall be calculated for each pollutant as follows:

Where:

Mi1 = mass emission of the pollutant i in g/km interpolated to 6,400 km;

Mi2 = mass emission of the pollutant i in g/km interpolated to 160,000 km.

These interpolated values shall be carried out to a minimum of four places to the right of the decimal point before dividing one by the other to determine the deterioration factor. The result shall be rounded to three places to the right of the decimal point.

If a deterioration factor is less than one, it is deemed to be equal to one. At the request of a manufacturer, an additive exhaust emission deterioration factor shall be calculated for each pollutant as follows:

D. E. F. = Mi2 – Mi

(Annex L - Appendix L1) (Standard Bench Cycle (SBC))

1. Introduction

The standard ageing durability procedure consists of ageing a catalyst/oxygen sensor system on an ageing bench which follows the standard bench cycle (SBC) described in this Appendix. The SBC requires the use of an ageing bench with an engine as the source of feed gas for the catalyst. The SBC is a 60-second cycle which is repeated as necessary on the ageing bench to conduct ageing for the required period of time. The SBC is defined based on the catalyst temperature, engine air/fuel (A/F) ratio, and the amount of secondary air injection which is added in front of the first catalyst.

2. Catalyst Temperature Control

2.1. Catalyst temperature shall be measured in the catalyst bed at the location where the highest temperature occurs in the hottest catalyst. Alternatively, the feed gas temperature may be measured and converted to catalyst bed temperature using a linear transform calculated from correlation data collected on the catalyst design and ageing bench to be used in the ageing process.

2.2. Control the catalyst temperature at stoichiometric operation (01 to 40 seconds on the cycle) to a minimum of 800 °C (±10° C) by selecting the appropriate engine speed, load, and spark timing for the engine. Control the maximum catalyst temperature that occurs during the cycle to 890 °C (±10 °C) by selecting the appropriate A/F ratio of the engine during the "rich" phase described in the table below.

2.3. If a low control temperature other than 800 °C is utilized, the high control temperature shall be 90 °C higher than the low control temperature.

The ageing bench shall provide the appropriate exhaust flow rate, temperature, air-fuel ratio, exhaust constituents and secondary air injection at the inlet face of the catalyst.

The standard ageing bench consists of an engine, engine controller, and engine dynamometer. Other configurations may be acceptable (e.g. whole vehicle on a dynamometer, or a burner that provides the correct exhaust conditions), as long as the catalyst inlet conditions and control features specified in this appendix are met.

A single ageing bench may have the exhaust flow split into several streams providing that each exhaust stream meets the requirements of this appendix. If the bench has more than one exhaust stream, multiple catalyst systems may be aged simultaneously.

3.2. Exhaust System Installation

The entire catalyst(s)-plus-oxygen sensor(s) system, together with all exhaust piping which connects these components, will be installed on the bench. For engines with multiple exhaust streams (such as some V6 and V8 engines), each bank of the exhaust system will be installed separately on the bench in parallel.

For exhaust systems that contain multiple in-line catalysts, the entire catalyst system including all catalysts, all oxygen sensors and the associated exhaust piping will be installed as a unit for ageing. Alternatively, each individual catalyst may be separately aged for the appropriate period of time.

3.3. Temperature Measurement

Catalyst temperature shall be measured using a thermocouple placed in the catalyst bed at the location where the highest temperature occurs in the hottest catalyst. Alternatively, the feed gas temperature just before the catalyst inlet face may be measured and converted to catalyst bed temperature using a linear transform calculated from correlation data collected on the catalyst design and ageing bench to be used in the ageing process. The catalyst temperature shall be stored digitally at the speed of 1 hertz (one measurement per second).

3.4. Air/Fuel Measurement

...

...

...

Please sign up or sign in to your TVPL Pro Membership to see English documents.



3.5. Exhaust Flow Balance

Provisions shall be made to assure that the proper amount of exhaust (measured in grams/second at stoichiometry, with a tolerance of ±5 grams/second) flows through each catalyst system that is being aged on the bench.

The proper flow rate is determined based upon the exhaust flow that would occur in the original vehicle’s engine at the steady state engine speed and load selected for the bench ageing in sub-paragraph 3.6. of this Appendix.

3.6. Setup

The engine speed, load, and spark timing are selected to achieve a catalyst bed temperature of 800 °C (±10 °C) at steady-state stoichiometric operation.

The air injection system is set to provide the necessary air flow to produce 3.0 per cent oxygen (±0.1 %) in the steady-state stoichiometric exhaust stream just in front of the first catalyst. A typical reading at the upstream A/F measurement point (required in paragraph 5) is lambda 1.16 (which is approximately 3 per cent oxygen).

With the air injection on, set the "Rich" A/F ratio to produce a catalyst bed temperature of 890 °C (±10 °C). A typical A/F value for this step is lambda 0.94 (approximately 2 per cent CO).

3.7. Ageing Cycle

The standard bench ageing procedures use the standard bench cycle (SBC). The SBC is repeated until the amount of ageing calculated from the bench ageing time equation (BAT) is achieved.

...

...

...

Please sign up or sign in to your TVPL Pro Membership to see English documents.



The temperatures and A/F ratio in paragraphs 3.3. and 3.4. of this appendix shall be reviewed periodically (at least every 50 hours) during ageing. Necessary adjustments shall be made to assure that the SBC is being appropriately followed throughout the ageing process.

After the ageing has been completed, the catalyst time-at-temperature collected during the ageing process shall be tabulated into a histogram with temperature groups of no larger than 10 °C. The BAT equation and the calculated effective reference temperature for the ageing cycle according to paragraph 2.3.1.4. of Annex L will be used to determine if the appropriate amount of thermal ageing of the catalyst has in fact occurred. Bench ageing will be extended if the thermal effect of the calculated ageing time is not at least 95 per cent of the target thermal ageing.

3.9. Startup and Shutdown

Care should be taken to assure that the maximum catalyst temperature for rapid deterioration (e.g., 1050 ° C) does not occur during startup or shutdown. Special low temperature startup and shutdown procedures may be used to alleviate this concern.

4. Experimentally Determining the R-Factor for Bench Ageing Durability Procedures

The R-Factor is the catalyst thermal reactivity coefficient used in the bench ageing time (BAT) equation. Manufacturers may determine the value of R experimentally using the following procedures.

4.1. Using the applicable bench cycle and ageing bench hardware, age several catalysts (minimum of 3 of the same catalyst design) at different control temperatures between the normal operating temperature and the damage limit temperature. Measure emissions (or catalyst inefficiency (1-catalyst efficiency)) for each exhaust constituent. Assure that the final testing yields data between one- and two-times the emission standard.

4.2. Estimate the value of R and calculate the effective reference temperature (Tr) for the bench ageing cycle for each control temperature according to sub-paragraph 2.2.3.4. of Annex L.

4.3. Plot emissions (or catalyst inefficiency) versus ageing time for each catalyst. Calculate the least-squared best-fit line through the data. For the data set to be useful for this purpose the data should have an approximately common intercept between 0 and 6400 km. See the following graph for an example.

4.4. Calculate the slope of the best-fit line for each ageing temperature

4.5. Plot the natural log (ln) of the slope of each best-fit line (determined in step 4.1.4.) along the vertical axis, versus the inverse of ageing temperature (1/(ageing temperature, deg K)) along the horizontal axis, Calculate the least squared best-fit lines through the data. The slope of the line is the R-factor. See the following graph for an example.

4.6. Compare the R-factor to the initial value that was used in Step 4.1.2. If the calculated R-factor differs from the initial value by more than 5 per cent, choose a new R-factor that is between the initial and calculated values, and then repeat the Steps 4.1.2 to 4.1.6 to derive a new R-factor. Repeat this process until the calculated R-factor is within 5 per cent of the initially assumed R-factor.

4.7. Compare the R-factor determined separately for each exhaust constituent. Use the lowest R-factor (worst case) for the BAT equation.

For particulate filters, the number of regenerations is critical to the ageing process. For systems that require desulphurisation cycles (e.g. NOx storage catalysts), this process is also significant.

 The standard diesel bench ageing durability procedure consists of ageing an after-treatment system on an ageing bench which follows the standard bench cycle (SDBC) described in this appendix. The SDBC requires use of an ageing bench with an engine as the source of feed gas for the system.

During the SDBC, the regeneration/desulphurisation strategies of the system shall remain in normal operating condition.

2. The Standard Diesel Bench Cycle reproduces the engine speed and load conditions that are encountered in the SRC cycle as appropriate to the period for which durability is to be determined. In order to accelerate the process of ageing, the engine settings on the test bench may be modified to reduce the system loading times. For example the fuel injection timing or EGR strategy may be modified.

3. Ageing Bench Equipment and Procedures

3.1. The standard ageing bench consists of an engine, engine controller, and engine dynamometer. Other configurations may be acceptable (e.g. whole vehicle on a dynamometer, or a burner that provides the correct exhaust conditions), as long as the after-treatment system inlet conditions and control features specified in this appendix are met.

A single ageing bench may have the exhaust flow split into several streams provided that each exhaust stream meets the requirements of this appendix. If the bench has more than one exhaust stream, multiple after-treatment systems may be aged simultaneously.
