A method of inspecting a ceramic wall-flow filter (1) for a vehicle exhaust system includes the steps of: a) providing a source (9) of heat energy suitable for heating material within the filter (1); b) applying heat energy from the source (9) to a first end (10) of the filter (1) to heat material within the filter; c) detecting infrared radiation (18) which has been emitted by heated material in the filter using a radiation detector (19) at the second end (11) of the filter (1) to form an image (24) of a pattern of emitted radiation, the pattern of emitted radiation providing an indication of the condition of the filter (1). Another aspect of the invention provides apparatus for use in the method.
摘要:
This invention is a microwave added filter core for engine exhaust. It emphasizes a filter core (1) which can heat and burn the micro particles (accumulated carbon) accumulated inside the passage of the filter core, or advance the working time of the filter core (1), or advance the catalysis of the filter core by means of the radiation of the microwave. The major invention is that one microwave device (2) is placed inside the exhaust filter core (1) of the engine, or at one end of the inlet or outlet of the ceramic catalyst filter. In order to prevent the radiation leaking, there is a metal net (3) at the exhaust filter core (1) in the engine exhaust pipe (A), or at another end of the ceramic catalyst filter. By means of such structural design, the micro particles accumulated inside the passage of the filter core can be burnt directly by the high temperature of the microwave radiation. It doesn't need to be through or wait for the self-burning of the catalyst covering on the surface of the passage of the filter core. Furthermore, the high radiation heat can directly heat the catalyst on the passage of the filter core, and advance the catalysis or advance the working time of the ceramic catalyst filter. It effectively enhances the temperature of the start burning. By means of this principle, this invention can be used in the engine filter cores of different fuels. The filter cores with different fuels will create different effects.
