Ceramic Composite for Diesel Particulate Filter (DPF)

摘要

Diesel engine is the most efficient power plant among all known types of internal combustion engines. The Diesel Engine is major candidate to become the power plant of the future. Environmental benefits of Diesel such as low green house gas emissions are balanced by growing concern with emission of Nitrogen oxide (NO_x) and Diesel Particulates (PM). The concern over Diesel particulate has increased in recent year because they are capable of causing lung cancer (size range of 0.1 to 1.0 micro meters). While developing the foam type diesel particulate filters (DPF) with indigenous ceramic materials, the main aim is to develop required porous structure for DPF with substantial strength, through which diesel exhaust filtrate with low back pressure to minimize loss of engine performance and with high trapping efficiency to reduce the particulate matter. The developed Diesel particulate filters are inexpensive and have shown satisfactory opacity reduction (70%).
