Diesel Particulate Filters
Modern diesel engines have decreased emissions, but still emit particulate matter with a wide range of particle size. Therefore tighter PM emission standards are being introduced in the United States, Japan and Europe for both passenger cars and heavy duty vehicles. To meet the regulations and to overcome the health concerns relating to particulate emissions from diesel engines, wall flow particulate filters are considered as a viable measure to minimise soot emission. For cleaning the particulate emissions of diesel engines, NGK has developed diesel particulate filters (DPF) based on ceramic substrate Technology. The DPF has demonstrated impressive characteristics:
-
Superior filtration efficiency.
-
Superior thermal shock resistance.
-
Weight advantage.
Diesel Particulate Filter.
The DPF (Diesel Particulate Filter), based on the well-known HONEYCERAM® technology made of Cordierite and SiC(Silicon Carbide), has demonstrated high filtering efficiency of diesel particulate emissions. Applications of this technology include passenger cars, urban and school buses, on highway trucks, mining equipment, and forklift trucks.
