A New Economical Silicon Carbide Diesel Engine Particulate Filter

This paper presents the main properties of a SiC diesel particulate filter bonded with specific ceramic oxides at a markedly lower sintering temperature than normal pure SiC DPF.

The elasticity of the bond has been studied to have a good behavior to thermal shock permitting a larger cross section element and a reduction of the number of cement joints in the final monolith.

That new product, manufactured at present is composed of seven square elements. Endurance tests have been carried out by laboratory bench testing in two commercial automobile diesel engines.

The DPF pore size has been adjusted so that it may be catalyzed or impregnated.
