(1) The values quoted in the specifications are
"true values". In establishment of their limit values the terms of
ISO 4259 Petroleum products - Determination and application of precision data
in relation to methods of test have been applied and in fixing a minimum value,
a minimum difference of 2R above zero has been taken into account; in fixing a
maximum and minimum value, the minimum difference is 4R (R = reproducibility).
Notwithstanding this measure, which
is necessary for technical reasons, the manufacturer of fuels shall
nevertheless aim at a zero value where the stipulated maximum value is 2R and
at the mean value in the case of quotations of maximum and minimum limits. Should
it be necessary to clarify whether a fuel meets the requirements of the
specifications, the terms of ISO 4259 shall be applied.

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.
...

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.

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

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:

not be automatically deactivated without the reason for its activation having
been remedied.
K.8.7. Detailed written information fully
describing the functional operation characteristics of the driver inducement
system shall be provided to the approval authority at the time of approval.
K.8.8. As part of the application for type
approval under this Regulation, the manufacturer shall demonstrate the
operation of the driver warning and inducement systems.
K.9. Information requirements
K.9.1. The manufacturer shall provide all
owners of new vehicles written information about the emission control system. This
information shall state that if the vehicle emission control system is not
functioning correctly, the driver shall be informed of a problem by the driver
warning system and that the driver inducement system shall consequentially
result in the vehicle being unable to start.
K.9.2. The instructions shall indicate
requirements for the proper use and maintenance of vehicles, including the
proper use of consumable reagents.
K.9.3. The instructions shall specify if
consumable reagents have to be refilled by the vehicle operator between normal
maintenance intervals. They
shall indicate how the driver should refill the reagent tank. The information
shall also indicate a likely rate of reagent consumption for that type of
vehicle and how often it should be replenished.
K.9.4. The instructions shall specify that
use of, and refilling of, a required reagent of the correct specifications is
mandatory for the vehicle to comply with the certificate of conformity issued
for that vehicle type.

K.9.6. The instructions shall explain how
the warning system and driver inducement systems work. In addition, the consequences of
ignoring the warning system and not replenishing the reagent shall be
explained.
K.10. Operating conditions of the
after-treatment system
Manufacturers shall ensure that the
emission control system retains its emission control function during all
ambient conditions, especially at low ambient temperatures. This includes
taking measures to prevent the complete freezing of the reagent during parking
times of up to 07 days at 258 K (-15 °C) with the reagent tank 50 per cent
full. If the reagent has frozen, the manufacturer shall ensure that reagent
shall be available for use within 20 minutes of the vehicle starting at 258 K
(-15 °C) measured inside the reagent tank, so as to ensure correct operation of
the emission control system.

L.6.3.1.1. When the durability test is
performed on a chassis dynamometer, the dynamometer shall enable the cycle
described in sub-paragraph L.6.1. to be carried out. In particular, it shall be equipped
with systems simulating inertia and resistance to progress.
L.6.3.1.2. The brake shall be adjusted in order
to absorb the power exerted on the driving wheels at a steady speed of 80 km/h.
Methods to be applied
to determine this power and to adjust the brake are the same as those described
in Appendix D7 of Annex D to TCVN 6785:2015.
L.6.3.1.3. The vehicle cooling system should
enable the vehicle to operate at temperatures similar to those obtained on road
(oil, water, exhaust system, etc.).
L.6.3.1.4. Certain other test bench adjustments

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. The limit values
to be complied with are those laid down in Tables 1 and 2 paragraph 2 Part II
of this Regulation. 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

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:

(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
...

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.

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.
3.2. Exhaust System Installation
The entire after-treatment 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.
