| Abstract: | Two types of filter element structure with devious gas channels for particulates filtration from diesel exhaust were designed.The experiment for filtration efficiency and exhaust backpressure of filter was conducted.The experimental results show that improving the filter geometry structure could reduce exhaust backpressure significantly,decrease the influence of filter on the output power of diesel engine,improve the distribution of particles in the filter element,and increase the effective filtration volume of the filter. |
