The revised automobile emission terminology and definitions refer to the relevant national and Japanese automobile emission terminology and definition standards, the definitions in various automobile emission standards in the AE Manual, the definitions in Part 86 of the US Federal Regulations 40, and the definitions in various European automobile emission regulations, and are influenced by some automobile emission technical terms that have been widely used in my country and other countries around the world. This revision adds "fuel and energy" and "low emission vehicle" parts. In terms of "emissions", "emission control system", "test methods" and "standards and regulations", many new clauses are also added, such as "gasoline emission control system", "catalytic collector (filter) oxidation system", etc. For this reason, new changes are made in the arrangement of chapters. The content of the original version is basically retained, and only the inaccurate and incomplete parts of the original terms and definitions are corrected and supplemented. Appendix A and Appendix B of this standard are suggested supplements. This standard is proposed by the State Administration of Industry and Commerce. This standard is under the jurisdiction of the National Technical Committee for Automobile Standardization. The standard is issued by the China Automotive Technology Research Center Standardization Research Institute. The standard was first issued in January 2011, and the China Automotive Technology Research Center Standardization Research Institute is responsible for the interpretation of this standard. 1 Scope

A device that uses a catalytic agent to reduce the hydrogenated compounds, oxides and hydroxides in the exhaust gas. It is mainly composed of a shell, a carrier and a catalytic agent. According to the type of catalytic agent, it can be divided into three types: oxidizing type, reducing type and three-way catalytic converter
Catalytic converter in which the exhaust gas contacts the catalytic converter along the exhaust gas
Catalytic converter in which the exhaust gas contacts the catalytic converter in a radially core-shaped manner
Catalytic converter in which the exhaust gas contacts the catalyst in a multi-layered manner
Catalytic converter in which the exhaust gas contacts the catalyst downward
Catalytic converter in which the exhaust gas contacts the catalyst upward
The reducing or three-way catalytic bed and the oxidizing catalytic bed in the catalytic converter are respectively installed in the exhaust gas separator, and the exhaust gas flows through the reducing or three-way catalytic bed In the oxidation process, a device for supplying secondary gas is provided in front of the oxidation catalyst. A catalytic converter with a chemical bed is installed in the device. A system using two chemical beds, one is an oxidation bed and the other is a reduction bed, is used to reduce the nitrogen compounds in the exhaust gas. Emulsify nitrogen oxides and nitrogen oxides. These two catalytic beds can be installed in one device or in two separate replacement devices. The catalytic converter installed during the vehicle type approval or the catalytic converter store that has been certified to replace the original catalytic converter or the catalytic converter store adds a substance to the reverse chemical reaction, but the body does not participate in the chemical reaction. A catalytic agent that rapidly oxidizes nitrogen oxides and nitrogen oxides into water vapor and carbon monoxide. 2. 2. 2. 1. 2, 2

a oxidizing agent for chemical reactions with nitrogen and its compounds, free nitrogen (H,) or hydrocarbons. The ideal chemical reaction is oxygen, monoxide and water
a catalyst for both oxidizing and reducing compounds. In order to obtain the best conversion rate, the engine must operate in a very narrow air-fuel ratio range (close to the current theoretical ratio state). Use one or more metals (such as copper, platinum, palladium, tin or ruthenium) as the active material. Use one or more common metals (such as copper, platinum, chrome, diamond) as the active material. Use rare earth elements (such as chrysene and orthoclase) as the activating material. The catalyst is broken due to the influence of temperature and other factors. The catalyst bed is reduced in size and its value is reduced. The area of ​​​​the activating material is reduced. When there are bitter substances (such as estimated After entering the chemical converter, the chemical will be deposited on the surface of the chemical, weakening or eliminating the chemical conversion ability of the chemical. The total surface area of ​​the catalyst per unit mass (including the surface area of ​​the micropores of the catalyst), generally expressed as m/s. The non-gas flow rate (m/s) measured under standard humidity and pressure conditions is expressed as the carrier volume (m) as the space construction (s-). The chemical will also decline with the passage of working time. The material used to increase the surface area of ​​the catalyst deposited on the carrier when the chemical can work normally. 2. 2. 2. 1. 4

used to purify carbon monoxide and monoxide in the exhaust gas, kind of equipment. It is often an exhaust gas container with an internal duct or two heat layers with a large volume, so that the exhaust gas remains in a highly condensed state after leaving the engine combustion chamber to continue combustion. A thermal preheating device characterized by operating at an air-fuel ratio greater than the theoretical air-fuel ratio range. A thermal reheat chamber characterized by operating at an air-fuel ratio less than the theoretical air-fuel ratio range. An exhaust gas recovery pipe with a large volume: to accelerate the thermomechanical reaction of the exhaust gas. t||Control device to protect the heat exchanger from overheating due to abnormal chemical reaction
A device to send out an alarm when the temperature of the heat exchanger exceeds the control range
In order to reduce the heat loss of exhaust gas, the metal plate or ceramic parts in the heat exchanger
In order to reduce the heat loss of exhaust gas, the bushing in the port is made of metal plate or ceramic
In order to purify the exhaust gas, the carbon monoxide in the exhaust gas is burned again. Among them,
is the mechanism for igniting or igniting the exhaust gas
In order to carry out the thermal reaction, the system supplies air to the exhaust system
is the air supply to the exhaust system for purifying the hydrocarbons, monoxides and organic matter in the exhaust gas, and the air supplied by the exhaust system is distributed to the manifolds of each gas port in proportion. This duct may include external pipes or channels connected to the manifold. Secondary air control. According to the operating conditions of the engine, the secondary air valve should be designed to be airtight to provide a reliable seal.2. 2. 2. 1
