18、devrForeword 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

19、 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 mat

20、ters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circu

21、lated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be

22、 held responsible for identifying any or all such patent rights. ISO 16183 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 5, Engine tests. Annexes A, B and C form a normative part of this International Standard. Annex D is for information only. BSISO16183:2002IS:38161

23、O2002(E) I SO 2002 All irthgs ersedevr vIntroduction Todays emission measurement systems depend on the type of test cycle steady-state or transient and the type of pollutant to be measured. In a steady-state cycle, the mass of gaseous emissions is calculated from the concentration in the raw exhaust

24、 gas and the exhaust flow of the engine, which can easily be determined. For particulate matter (PM), partial-flow dilution systems, in which only a portion of the exhaust gas is diluted, are widely used. In a transient cycle, real time exhaust flow determination is more difficult. Therefore, the co

25、nstant volume sampling (CVS) principle has been used for many years because exhaust mass flow measurement is not required with this system. The total exhaust gas is diluted, the total flow as the sum of dilution air and exhaust gas volume is kept virtually constant, and the emissions (both gaseous a

26、nd PM) are measured in the diluted exhaust gas. The space and cost requirements of such a system are considerably higher than for the partial-flow dilution systems used in steady-state cycles. Nevertheless, raw exhaust measurement and partial flow systems can only be applied to transients if sophist

27、icated control systems and calculation algorithms are used. The mass emission determination in a raw exhaust sample and the measurement of the exhaust gas mass flow rate is a state-of-the-art procedure for light duty vehicle development on chassis dynamometers. There it is called modal analysis. How

28、ever, it is usually done in conjunction with the mass emission evaluation on a full-flow CVS with bag analysis, where quality of the modal results can easily be verified by comparison with the CVS bag results. For heavy-duty engines, the CVS system is a large and costly system. The aim of this Inter

29、national Standard is to provide an optional, stand-alone measurement procedure. By the nature of the transient mass emission calculation, small changes could result in large deviations of the final results, for example, by a wrongly performed time alignment caused by a wrong response time determinat

30、ion or by a system fault resulting in a change of the response time behaviour of the system. Therefore, the quality assurance procedure of a carbon dioxide-based carbon balance check, in line with highly sophisticated verification procedures for the partial flow particulate measurement, have been es

31、tablished in this International Standard. NOTE CVS systems are covered in detail in various exhaust emissions regulations for both light- and heavy-duty vehicles as well as by ISO 8178-1. They are therefore not included in this International Standard. Since they are considered to be the reference sy

32、stems for exhaust emission measurement on transient cycles, extensive studies have been commissioned by ISO/TC 22/SC 5/WG 2 on the correlation between CVS systems and the systems covered by this International Standard, with the results having been taken into consideration in its development.

This I

The test equipment specified in this International Standard can also be used in steady-st
