    摘要： A diesel particulate trap formed from silicon carbide cermet foam with associated hardware to retain the foam in a particular configuration. Several pieces of the foam, in the shape of "doughnuts", are stacked on top of each other. The stack of foam doughnuts is assembled in a container designed to allow diesel exhaust to flow radially inward through the doughnuts and exit through the center. Ceramic felt gaskets are interposed between the doughnuts and between each of the end doughnuts and steel end plates. These gaskets serve as buffers and allow for different thermal expansion properties of the steel and silicon carbide cermet foam. The silicon carbide is conducting and has resistance and when current is passed through the foam doughnuts, they become hot enough to burn the collected particulate.

    摘要： A method for simulating at least one drive cycle of a vehicle using a non-engine based test system, the method including providing a non-engine based test system including a combustor in fluid communication with a catalytic converter from the vehicle; supplying fuel and air to said combustor at an air to fuel ratio (AFR) and under conditions effective to produce a feedstream flowpath; substantially stoichiometrically combusting at least a portion of the fuel in the feedstream flowpath under conditions effective to simulate at least one drive cycle of the vehicle and to produce a simulated drive cycle exhaust product for the vehicle, the conditions being effective to prevent substantial damage to the combustor; and, collecting and analyzing the simulated drive cycle exhaust product.
