Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national standards bodies (ISO member bodies). The work of
preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be represented
on that committee. International organizations, governmental and non-
governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 8178-5 was prepared by Technical Committee
ISO/TC 70, Internal combustion engines, Subcommittee SC 8, Exhaust gas
emission measurement.
ISO 8178 consists of the following parts, under the general title
Reciprocating internal combustion engines — Exhaust emission
measurement:
— Part 1: Test-bed measurement of gaseous and particulate exhaust
emissions
— Part 2: Measurement of gaseous and particulate exhaust emissions at
site
— Part 3: Definitions and methods of measurement of exhaust gas

INTERNATIONAL STANDARD  ISO ISO 8178-5:1997(E)
Reciprocating internal combustion engines — Exhaust emission
measurement —
Part 5:
Test fuels
1  Scope
This part of ISO 8178 specifies fuels whose use is recommended for performing the exhaust emission test cycles
given in ISO 8178-4.
NOTE —  Since fuel properties vary widely from country to country a broad range of different fuels is listed in this part of
ISO 8178 — both reference fuels and commercial fuels.
This part of ISO 8178 is applicable to reciprocating internal combustion engines for mobile, transportable and
stationary installations excluding engines for motor vehicles primarily designed for road use. This part of ISO 8178
may be applied to engines used e.g. on earth-moving machines, generating sets and for other applications.
Reference fuels are usually representative of specific commercial fuels but with considerably tighter specifications.
Their use is primarily recommended for test bed measurements described in ISO 8178-1.
For measurements typically at site where emissions with commercial fuels, whether listed or not in this part of
ISO 8178 are to be determined, uniform analytical data sheets (see clause 5) are recommended for the
determination of the fuel properties to be declared with the exhaust emission results.

5  Choice of fuel
As far as possible, reference fuels should be used for certification of engines.
Reference fuels reflect the characteristics of commercially available fuels in different countries and are therefore
different in their properties. Since fuel composition influences exhaust emissions, emission results with different
reference fuels are not usually comparable. For lab-to-lab comparison of emissions even the properties of the
specified reference fuel are recommended to be as near as possible to identical. This can theoretically best be
accomplished by using fuels from the same batch.
For all fuels (reference fuels and others) the analytical data shall be determined and reported with the results of the
exhaust measurement.
For non reference fuels the data to be determined are listed in the following tables:
— table 1, Universal analytical data sheet — Natural gas
— table 2, Universal analytical data sheet — Liquefied petroleum gas
— table 6, Universal analytical data sheet — Motor gasolines
— table 11, Universal analytical data sheet — Diesel fuels
— table 13, Universal analytical data sheet — Distillate fuel oils
— table 14, Universal analytical data sheet — Residual fuel oils
— table 15, Universal analytical data sheet — Crude oil
An elemental analysis of the fuel shall be carried out when the possibility of an exhaust mass flow measurement or
combustion air flow measurement, in combination with the fuel consumption, is not possible. In such cases the
exhaust mass flow can be calculated using the concentration measurement results of the exhaust emission, and
using the calculation methods given in ISO 8178-1:1996, annex A (see also annex A of this part of ISO 8178).
Hydrogen and carbon mass fractions can be obtained by calculation or nomogram. The recommended methods are
given in A.3.1, A.3.2 and A.3.3.
NOTE —  For non-ISO test methods equivalent to those of ISO standards mentioned in this part of ISO 8178, see annex B.
5.1  Natural gas
Gaseous fuels are not referenced as their use depends on the availability of the gas at site. Their properties,
including the fuel(s) analysis shall be known and reported with the results of the emissions test.
A universal data sheet containing the analytical properties to be reported is given in table 1.
5.2  Liquefied petroleum gas
Liquefied petroleum gas is not referenced as its use depends on the availability of the gas at site. The properties,
including the gas analysis, shall be known and reported with the results of the emissions test.
A universal data sheet containing the analytical properties to be reported is given in table 2.

5.3  Motor gasolines
5.3.1  Referenced motor gasolines
The referenced motor gasolines whose use is recommended for certification purposes are the following:
1)
a) CEC reference fuels: see table 3;
b) USA certification test fuel: see table 4;
c) Japanese certification test fuels: see table 5.
5.3.2  Non referenced motor gasolines
If it is necessary to use non referenced motor gasolines, the properties of the individual fuel shall be reported with
the results of the test. Table 6 represents a universal analytical data sheet giving the properties which shall be
reported.
Standards or specification of commercial fuels may be obtained from the organizations listed in annex C.
5.4  Diesel fuels
5.4.1  Diesel reference fuels
The referenced diesel fuels whose use is recommended for certification purposes are the following:
a) CEC reference fuels: see table 7;
b) USA certification test fuels: see table 8;
c) Californian test fuel: see table 9;
d) Japanese certification test fuel: see table 10.
5.4.2  Non referenced diesel fuels
If it is necessary to use non referenced diesel fuels, the properties of the individual fuel shall be reported with the
results of the test. Table 11 represents a universal analytical data sheet giving the properties which shall be
reported.
Standards or specifications of commercial fuels may be obtained from the organizations listed in annex C.
5.5  Distillate fuel oils
As there are no existent reference fuels, it is recommended that the fuel used be in accordance with ISO 8216-1
and ISO 8217 (see table 12).
The fuel's properties, including the elemental analysis, shall be measured and reported with the results of the
emission measurement. Table 13 represents a universal analytical data sheet giving the properties which shall be
reported.
2)
ISO 8216-1 and ISO 8217 do not specify ignition quality, as the CFR engine measurement procedure is not
applicable for fuels containing residues.
The effect of the ignition quality on exhaust gas emissions depends on the engine characteristics and engine speed
and load, and is in many cases not negligible. There is a generally recognized need for a standard measurement
procedure resulting in a characteristic fuel quality value comparable to the cetane number for pure distillate fuels. A
calculation based on the distillation characteristics is not suitable. For the time being the best approach is to
calculate CCAI (Calculated Carbon Aromaticity Index) or CII (Calculated Ignition Index) figures for general
indication. It is too early to specify a supplementary maximum ignition quality level in the fuel specification during
exhaust emission acceptance tests. Clause A.4 gives equations for CCAI and CII.

5.6  Residual fuel oils
No existent referenced fuels.
In cases where it is necessary to run on heavy fuels, the properties of the fuel shall be according to ISO 8216-1 and
ISO 8217. The properties of the fuel, including the elementary analysis, shall be determined, and reported with the
results of the emission measurement. Table 14 represents a universal analytical data sheet giving the properties
which shall be reported.
ISO 8216-1 and ISO 8217 do not specify ignition quality, as the CFR engine measurement procedure is not
applicable for fuels containing residues.
The effect of the ignition quality on exhaust gas emissions, especially NO depends on the engine characteristics
x
and engine speed and load, and is in many cases not negligible. There is a generally recognised need for a
standard measurement procedure resulting in a characteristic fuel quality value comparable to the cetane index for
pure distillate fuels. A calculation based on the distillation characteristics is not suitable. For the time being, the best
approach is to calculate CCAI (Calculated Carbon Aromaticity Index) or CII (Calculated Ignition Index) figures for
general indication. It is too early to specify a supplementary maximum ignition quality level in the fuel specification
during exhaust emission acceptance tests. Clause A.4 gives equations for CCAI and CII.
5.7  Crude oil
Crude oils are non referenced.
In cases where it is necessary to run the engine with crude oil, the properties of the fuel, including the elemental
analysis, shall be measured and reported with the results of the emission measurement. Table 15 is given as a
recommendation for a data sheet, of the properties to be reported.
5.8  Alternative fuels
In those cases where alternative fuels are used, the analytical data specified by the producer of the fuel shall be
determined and reported together with the report on exhaust emissions.
6  Requirements and additional information
For the determination of fuel properties ISO standards shall be used where they exist. Annex B lists standards,
established by the standardization organizations, in use in parallel to ISO standards.
If supplementary additives are used during the test they shall be declared and noted in the test report.
If water addition is used it shall be declared and taken into account in the calculation of the emission results.
It should be noted that distillates and residual fuel oil typically have a high ash and sulfur content and this will
normally result in high particulate levels. In the case of sulfur, this is due to the formation of sulfates and associated
water during the dilution.
It should be noted that nitrogen content of the fuel increases the NO emission.
