ISO Foreword
International Organization for Standardization (ISO) is a global association of 15 national standardization bodies. The work of preparing International Standards is generally carried out by 15 technical committees: each member body has the right to send representatives to participate in the establishment of a committee for a certain topic of interest. Non-governmental international organizations may also participate in this work through cooperation with ISO. In all aspects of standardization work, ISO) has close cooperation with the International Electrotechnical Commission (IEC). The international standard draft agreed upon by the technical committee of the International Organization for Standardization (ISO) is distributed to all member groups. At least one member group shall pay for the publication of the standard as an international standard. The standard S08179-2 was prepared by the ISO Technical Committee on Internal Combustion Engines (ISO/TC 70) Subcommittee on Non-emission Measurement (S08178). Under the general title "Emission measurement of internal combustion engines", it consists of the following parts: Part 1: Test bench measurement of gaseous and particulate emissions. Part 2: Field measurement of gaseous and particulate emissions. Part 3: Filter performance measurement of exhaust gases. Part 4: Test environment for motor vehicles Part 5: Test fuels Part 1: Test report Part 2: Determination of engine family Part 3: Engine system specification Part 4: Test for exhaust gas fouling of engines for non-road mobile machinery This standard is for reference only. 1 Scope National Standard of the People's Republic of China Exhaust efficiency measurement of reciprocating internal combustion engines Part 2: Field measurement of gaseous and particulate emissions Reciprncating intetnal comhustkm enginesCB/T8190.2--1999

Exhaul mission mearerementFartZ;Measurement onHaseot and particulate evhaust emissions at gite standard (B/T8190.-6) specifies the test and evaluation methods for reciprocating internal combustion engines under steady-state conditions to determine the compensation of each exhaust pollutant. See GB/18150.47.
This standard is recommended for reciprocating internal combustion engines that need to be measured under on-site conditions and cannot be used in the test center. They cannot be left in the test center. They cannot be used in the station. This standard is not applicable to vehicles driven by non-road engines, such as agricultural tractors and harvesters, taxi machines, large trucks (generally used for highway maintenance), general-purpose equipment and the rate of use of public utility vehicles. The engines driving these equipment must be certified on the test bench. If this engine is to be re-installed or re-certified, it is best to use a suitable load and test panel outside the vehicle for testing, such as dynamometer testing.
This method can be used for new engines that are easily refitted and re-installed: After modification, the engine can also be verified by the relevant B/T90.4 test frame. The engine's running performance and endurance test points must be the same as those used in the laboratory test; but there are certain differences between the running parameters and the old engine in the laboratory: when used on an engine with additional health requirements (occupational health, safety systems, power plant regulations), it may be necessary to supplement the test conditions with special evaluation methods:
Note 1: This standard is used to determine the performance of new engines in the presence of special requirements. The engine and the vehicle must maintain the same emission standards as the test vehicle. The test station is at a higher level on the test bench, and the better performance test method is used. The test bench quantity required before re-determining the standard is to represent the actual power of the typical reverse motor. The test environment of GB/TX9U1 specification is changed due to the quantity load, and the end point cannot be reproduced on site. The following requirements and conditions must be carried out in the field. When the on-site conditions cannot be controlled, and the type test is not suitable for the test, this test is a substitute for the test bench test. Therefore, the test environment should be carried out according to the test data environment given in G/T8190.4. Example
1) When the test bench is limited by the fuel supply or bad points and cannot quickly represent the actual fuel used, 2》When the test environment conditions are different due to the height, humidity and air density, and cannot represent the standard conditions. In this case, this standard is applicable to some engines that can meet the requirements of 81904 on site, such as general engines that will be put on trial, main transformers installed for the first time, and engines on diesel-electric locomotives. b) In order to assess the actual pollution situation, it is necessary to fully test the type. This should be carried out under actual or simulated working conditions. The engine cannot always be left GP/T8193.4. The test cycle is determined by the parties concerned. However, the test sequence should be as close to the test cycle as possible. Therefore, the measured values under these conditions cannot be truly compared with the test bench results. In order to test the effectiveness of the test cycle, the test must be carried out on site. e) When the on-site test is conducted by the parties concerned, the measured values must represent the specific conditions of the relevant machine under the specific on-site conditions, and the technical parameters must be representative of the typical values. The values determined by the test station will be largely determined by the test environment. Therefore, in most cases, the measured values cannot be compared with the test bench results. d: In order to test the effectiveness of the modified machine or the standard machine, the on-site test must be conducted. If the test bench and the test disk cannot be used together, the emission value will not be equal to the value measured in the test. Therefore, the measurement must be carried out in accordance with the test bench certification company's operation. 2 Reference standards || tt || The following referenced articles are all valid, and all standard versions will be revised.

Part 5: Test Methods for Mixing of Internal Combustion Engines Using the following definitions: 3.-1 Farticulae A substance obtained by mixing with clean air from a non-gas source, with the temperature of the gas measured at 1°C equal to or greater than 325 K at 52°C. Its main components are intercalated carbon compounds, condensable carbon compounds, and water. 3.2 Partial flow dilution method: Part of the original exhaust gas is separated from the total exhaust flow and combined with suitable dilution air, and then passed through a filter [see GB/T8190.1:9934116.1.1+16~13] 3.3 Full-flow dilution method: First, the original exhaust gas is mixed with the total exhaust flow, and then a part of the exhaust gas is separated and separated. The whole exhaust gas is filtered and filtered. 3: In the evaluation of multiple values, the system is adjusted to select the gas inlet and outlet to meet the standard, so that the gas containing the same amount of chain is effectively reversed and sent to the same position.

The weighting coefficient of the condition is considered in the test data verification stage after sampling.
3.7 Total multiplexer The method of using a single filter for all test cycle conditions. The weighting coefficient of the condition needs to be considered in the test sampling stage.
