摘要:
In a method and apparatus for configuration of networked controllers in a vehicle that can be manufactured with various outfitting variants (that is, differing components and features), at least one controller being configurable to different outfitting variants of the vehicle, characterizing information is stored for the various outfitting variants of the vehicle. The data for configuring the controllers are stored in an outfitting variant controller on board the vehicle. A particular controller that is to be configured in this manner transmits characterizing information to the outfitting variant controller for configuration to a specified outfitting variant of the vehicle in which it is installed. The outfitting variant controller assembles the data for configuring the particular controller using the characterizing information and the data stored on the outfitting variant controller. The data assembled in this manner are written into a memory unit of the particular controller to configure to accommodate the specified outfitting variant.
摘要:
Coating a wall-flow filter with a catalytically active coating generally increases the exhaust-gas backpressure in the filter. The increase in the exhaust-gas backpressure is particularly pronounced if a slurry of fine-particle catalyst materials is used for the coating operation. The increase in the exhaust-gas backpressure can be restricted to a tolerable level if, prior to the coating operation, the slurry is so finely milled that virtually the entire mass of the catalyst materials is introduced into the pores of the filter and deposited on the inner surfaces of the pores. This is the case if the d90 diameter of the particles in the slurry is reduced to below 5 μm by milling.

The invention relates to particle filters having an open pore structure for separating particles from fluids, which, for modification of their properties or for treatment of the fluid to be filtered, are provided with additional metal oxides or mixed metal oxides and optionally with further catalytically active components. In particular, the invention relates to particle filters treated with a catalytically active material, which is used for the treatment of the waste gases from combustion processes, in particular for the treatment of the exhaust gases of internal combustion engines. By impregnation of the filter bodies in a solution of a metal oxide sol or a mixed metal oxide sol, the preformed sol particles are deposited on the pore surfaces. Consequently, catalytic activations of the filter with good temperature stability in combination with a moderate increase in the exhaust gas back-pressure are possible.
