Exhaust emission test after cold start at normal temperature (type I test)
C.1 Test procedure and test conditions
This Appendix describes the test procedures and test conditions for type I tests
specified in 5.3.1. For vehicles burning LPG or NG, the terms of Appendix L
shall also be applied.
C.1.1 Test description
C.1.1.1 In the specified type I test cycle, determine the gaseous contaminants,
particulate matter mass (PM), particulate matter number (particle number or
PN), and CO2 emissions.
C.1.1.1.1 Tests shall use the method described in this Appendix. The gas,
particulate and particle number shall be subject to sampling analysis by the
specified method. Hybrid vehicle testing is performed using the method
specified in Appendix R.
C.1.1.2 The number of tests is determined in accordance with Figure C.1.
C.1.1.2.1 The process specified in Figure C.1 applies to a complete type I test
cycle, it does not apply to a single speed segment of a type I test cycle.
C.1.1.2.2 The test result is the result after the REESS energy change, Ki, and
the deterioration factor correction.
C.1.1.2.3 Determination of test results
C.1.1.2.3.1 If any of the test results has a certain pollutant exceeding the
standard, the test vehicle emission is determined as disqualified.
C.1.1.2.3.2 The vehicle manufacturer shall declare the CO2 emissions of the
test vehicle during the entire test cycle in accordance with Table C.1.
C.1.1.2.3.3 If, after the first test, the test results meet the requirements of the
first test in Table C.2, the value of the type test shall be the value of the public
information of the manufacturer. Otherwise, a second test shall be conducted.
C.1.1.2.3.4 After the second test, calculate the arithmetic mean of the two test
results. If the arithmetic mean meets the requirements of the second test in
Table C.2, the type test value shall use the information disclosure value of the
C.1.2.1.3.1.3 Determine the background particulate level in the dilution channel
by collecting the dilution air passing through the particulate background gas
filter. The sampling point is the same as the particle sampling point. If a
secondary dilution is used for background level measurement, the secondary
dilution system shall be in working condition, and one background particle level
measurement shall be performed on the day of the test. The measurement of
background particles can be carried out either before the test or after the test.
C.1.2.1.3.2 Background particle number (PN) determination
C.1.2.1.3.2.1 It is allowed to perform background correction by subtracting the
number of particles in the dilution air or dilution channel from the emission
measurement results. The method for determining the number of background
particulates is as follows.
C.1.2.1.3.2.1.1 Background values can be calculated or actually measured. The
maximum allowable corrected background concentration is related to the
maximum allowable leakage (0.5/cm3) of the quantitative measurement system
which is corrected by the particle concentration reduction factor (PCRF), and
the CVS flow used in the actual test.
C.1.2.1.3.2.1.2 As required by the manufacturer, it may also use the actually
measured background concentration for correction.
C.1.2.1.3.2.1.3 If the result after subtracting background particles is negative,
the background particle number is considered to be zero.
C.1.2.1.3.2.2 The dilution air background particle number concentration shall
be determined by collecting dilution air which passes through the particulate
sampling filter. The sampling point shall be located as close to the dilution air
filter as possible within the PN measurement system. The background gas
concentration level is represented by the number of particles/m3 and shall be
determined by rolling the arithmetic mean of at least 14 times. The background
concentration is measured at least once a week.
C.1.2.1.3.2.3 Dilution channel background particle concentration shall be
determined by collecting dilution air which passes through a particulate
sampling filter. The sampling point shall be the same as the particle sampling
point. If a secondary dilution is used to measure the background level, the
secondary dilution system shall be in normal operation. A background
measurement shall be conducted on the day of the test, and it can be performed
before and after the emission test. The flow rate settings for the PCRF and CVS
during the background measurement shall be the same as those for the actual
test.
C.1.2.2 Environmental requirements and parameters

test cycle. Start the engine and drive the vehicle as specified in C.1.2.6.4.
C.1.2.6.3.7 Additional WLTC cycles may be carried out at the request of the
manufacturer or the competent department of environmental protection, so that
the vehicle and the control system can reach a stable working condition.
C.1.2.6.3.8 Additional pretreatment cycles shall be recorded.
C.1.2.6.3.9 If there is a possibility of residual particulate emissions,
pretreatment of sampling equipment is required. It is recommended to use the
vehicle for a pretreatment of 20 minutes of continuous operation under steady
driving conditions at 120 km/h. If necessary, pre-treatment can be performed
for a longer time or at a higher speed. If required, it shall, after the dilution
channel pretreatment, measure the dilution channel background concentration
before the vehicle test.
C.1.2.6.4 The start of the power system shall be performed by the starter device
in accordance with the manufacturer’s instructions.
Unless otherwise specified, the initial starting operating mode of the vehicle
cannot be switched.
C.1.2.6.4.1 If the vehicle is not started successfully or if a start error is indicated,
the test is invalid. The pretreatment shall be repeated and a new test shall be
conducted.
pretreatment or type I test is not valid.
C.1.2.6.10 After the cycle is completed, the engine shall be shut down. Vehicles
that have completed pre-treatment must not restart the engine until they are
