This innovative technology will provide better filtration performance and a new design space
Mann Hummel announced that it will introduce a new type of diesel particulate filter produced using innovative technologies and enter the diesel particulate ceramic filter market. The new product provides a new structural space and improves the filtration performance. It will be tested and installed in Ludwigsburg at the end of 2009. Mass production will begin in 2012 and the annual output will be about 60,000.
In order to meet current and future emission regulations, almost all modern diesel engines have particulate filters installed. These filters are usually made of special ceramics and can filter almost all carbon black particles in the exhaust system of an internal combustion engine. When the exhaust gas entering the closed path of the particulate filter passes through the porous ceramic wall of the filter, fine carbon black particles are filtered out. These agglomerated carbon blacks will be completely burned during the regeneration cycle, returning the filter to full capacity.
Man Hummel uses innovative concepts in the production of diesel particulate filters. Instead of using traditional cordierite and silicon carbide, the new product uses a combination of aluminum titanate, aluminum and titanium oxide ceramics. This new synthetic material has a higher temperature resistance than cordierite, and there is no large expansion of silicon carbide. By using this high-performance material, high-temperature combined filters can be produced.
Innovative production technology
Man Hummel has many years of experience in producing compact air filters. Its new diesel particulate filter media uses a modified compact paper air filter. Just as filters for air filters were developed, filter specialists developed uniform paper media using coil technology. In the production process, Man Hummel uses innovative ceramic coated paper (CCP) technology. The paper carrier media will be immersed in the ceramic slurry to fill the paper fiber with a slurry around it. The paper is burned before the diesel particulate filter is produced and the ceramic particles are also burned. Ceramic adhesives are embedded between the layers of filter paper when they are wrapped, and the channel automatically closes, which is the basic prerequisite for filtration. At the end of the new production process, the diesel particulate filter was made.
Compared with diesel particulate filters currently on the market, Man Humeer's new products will have a larger carbon black particle storage capacity. In addition, it can also reduce carbon dioxide emissions by reducing exhaust back pressure. The new product gives design engineers greater creative space in terms of installation space and design. Since the shape and size of the filter depends only on the shape of the paper carrier medium and the winding technology used, the new product will provide more flexibility and design space, especially in the channel structure and shape of the filter. prominent. Design engineers often need to change the number and structure of the filter channels in order to keep the conical channels and channel holes between the channels open. The new diesel particulate filter from MANHUMMEL can make this change even more. For speed and convenience.
More features
The products designed under the new concept of Man Hummer can also integrate more functions. The catalytic converter can be integrated in the filter housing in order to reduce the number of parts required and the installation space.
