By the Wuhan University of Wuhan Institute of Automotive Engineering Professor Romani and his team independent research and development of automobile exhaust comprehensive management system, recently in Beijing through the China Environmental Protection Department of Science and Technology Development Center organized the technical assessment, the evaluation committee said that the technology will significantly reduce the car Exhaust pollutant emissions, technical level to the leading domestic level, its social and environmental benefits significantly.
Studies have shown that vehicle exhaust emissions to a certain level, under the action of photochemical interaction with industrial waste gas and other pollutants in the atmosphere to produce fine particles (PM2.5).
In fact, the catalytic converter in the vehicle life is often replaced, the cost is expensive; on the other hand, the scrapped catalysis of the catalyst, the use of precious metal catalyst, Precious metals such as platinum and palladium will cause secondary pollution to land and water, 'said Rome.
Related experts are developing technology to replace the precious metal catalyst, such as from the Southwest Institute of the United States 'efficient lean gasoline engine technology.' Rome and its team combined with foreign advanced technology, after 7 years to develop waste gas recycling technology, by improving the tank Internal combustion conditions to solve the problem of purification within the machine to achieve the purpose of reducing emissions.
The principle of the integrated exhaust system is to introduce a portion of the exhaust gas into the engine, reducing the temperature inside the machine and reducing the oxygen content in the machine, thereby destroying the conditions under which the nitrogen oxides are produced.
China Environmental Protection Department issued the "China Motor Vehicle Environmental Management Annual Report (2017)" shows that in 2016 the global car ownership of nearly 900 million, is expected by the end of 2017, China in the car to reach 330 million, the national motor vehicle emissions Accounting for 44.725 million tons of carbon monoxide (CO) 34,193,000 tons, 42.2 million tons of hydrocarbons (HC), nitrogen oxides (NOx) 5,778,000 tons, particulate matter (PM) 534,000 tons of vehicles to become the total amount of pollution Of the main contributors, the emission of CO and HC more than 80%, NOx and PM2.5 more than 90%, automobile exhaust comprehensive management without delay.
'Our research and development of automotive exhaust gas treatment system products have been verified, can make the vehicle exhaust gas carbon monoxide, hydrocarbons, nitrogen oxides, an average reduction of more than 75% .Roraji also said that the national testing agencies and market practice shows that the car The exhaust gas comprehensive management system has a significant effect on light gasoline vehicles that do not meet the emission standards in the vehicle, and is also in line with the economic needs of the owner, 'said Rome.
