New Technology For Purifying Exhaust Gas From Diesel Engines
An increasing proportion of the Danish vehicle fleet consists of diesel vehicles. In urban areas diesel vehicles are causing air pollution (from carbon particles, nitrogen oxides (NOX)) and unburned hydrocarbons). As the European legislation tightens the rules for emissions, it will become more difficult and expensive to meet the requirements for particulate filters and DeNOx technologies.
A new four-year project at Risø DTU is going to develop an effective method for purifying flue gases, especially exhaust gases from diesel engines. The project has received DKK 17 million from the Danish Council for Strategic Research (the Programme Commission on Sustainable Energy and Environment).
Electrochemical flue gas purification
Existing solutions to air pollution require the installation of particulate filters and either an SCR catalyst (Selective Catalytic Reduction) a NOx absorber or recirculation of the exhaust gas. This leads to additional expenditure when modifying diesel vehicles to be less polluting.
Electrochemical flue gas purification has a number of advantages over existing filters making it attractive to target this research at the car industry. Purification of carbon particles, toxic nitrogen oxides (NOX) and unburned hydrocarbons from the exhaust can all happen in the same filter unit.
Another advantage of using electrochemical methods is that it is not necessary to add other substances to the fuel. In addition the filter can be produced without the use of precious metals. The current SCR technology typically uses the nitrogen-containing urea as a reducing agent to remove NOx from the exhaust.
The purification of exhaust gas will therefore be conducted independently of the engine operation. This technology could lead to significant fuel savings compared with leading alternative technologies. The technology could also be applied in the purification of flue gas from power plants, and possibly in the shipping industry.
Expansion of the research group
The ambitious research project will involve the employment of five PhDs and two postdocs in the near future. Together with the present research team they are going to further develop the technology into a successful prototype for use under realistic conditions in a diesel engine.
The project is led by Kent Kammer Hansen, Senior Scientist in the Fuel Cells and Solid State Chemistry Division at Risø National Laboratory for Sustainable Energy, the Technical University of Denmark. Also participating in the project are the Department of Mechanical Engineering at DTU and the company Dinex Emission Technology A / S.

Article Summary
With the increase in Danish car population there has been a major pollution problem. A new project at Ruso DTU is being made to purify the oil in the exhaust system causing less pollution. Some of the purification systems are a SCR catalyst and a NOx absorber. These are types of the Electrochemical purifacation system, meaning they take chemicals in the car exhaust system and purify them. The Electrochemical system is better for your car because it does not need to change your fuel (add new chemicals) and it purify’s the chemicals from one exhaust valve. A group of scientist are going to be working on this shortly and hopefully can be able to expand this system to other engines.
In urban areas fuled vehicles are causing air polution such as carbon particles
and nitogen oxides.
They are making a new project at Ris DTU is developing a new method for purifying flue gases and exaust gases from fuled engines.
The project is led by Kent Kammer Hanson.
They are going to further develop technology into use under realistic conditions in fuled engines.
This technology could lead to fuel changes.
This article is about new technology for purifying exhaust gas from diesel engines. In urban places diesel automobiles are the source of air pollution(from carbon particles nitrogen oxides (NOX)) and unburned hydrocarbons). Solutions to air pollution must contain the installation of particulate filters and either an SCR catalyst (Selective Catalytic Reduction) a NOx absorber or recirculation of the exaust gas. Plus, using electrochemical methods is that it doesn’t require other substances being added to the fuel. This technology might lead to fuel savings compared with other alternative technologies. They are going to continue developing the technology into a prototype for use under conditions in a diesel engine.
Due to all the Danish Diesel Running cars the workers at DTU have invinted robots to purify the diesel fuel. They do this by using Electrochemical flue gas purifacation: this method of purifying has more advantages over just filters Such as the purifacation of toxic Nitrogen Oxides Also Know As NOX.
The danish car population is increasing there is a growing problem. The problem is polution. most of the danish cars rely on deisel. That is filling the air with particles, like carbon and nitrogen oxides. Risø DTU is developing a new method to purify the gases. Hopefully this will abe a short term solution to the growing problem.
Scientists in Denmark are trying to develop a new filter to stop air pollution. They are looking at diesel engines. Currently, the diesel engines are polluting the air. Since European legislation is tightening down on emissions it will become more expensive to meet the requirements. A four-year project is being set up at DTU to fix this problem. Currently they are installing particulate filters and gas scrubbers. This would lead to additional costs. It is also bulky and requires modifications to the gas.
The project was given DKK 17 million from the Danish Council of Strategic Research. They are trying to develop an electrochemical flue gas purification system. With this system you don’t have to change the type of gas. The system can also be produced without using precious metals. If they are successful it will help the world massively.
1.An increasing proportion Danish vehicle fleet consists diesel vehicles
2.In some area’s Danish vihicles cause air pollution
3.It is the filling of air particals, like carbon and nitrogen.

5.The participating in the project are the Department of Mechanical Engineering.
Danish vehicles have increased the amount of disesel vehicles. Urban areas have caused air pollution using diesel vehicles. There has been a four year project to decrease the air pollution with a new method. The installation of particulate filters can mabye reduce air pollution with SCR, that can absorb the exhaust of gas. The electrochemical flue gas has purification that cpuld give them some advantages for filters making it attractive to sell in the industry of cars.
