Disclosed is a method for testing a catalytic converter (8) of an internal combustion engine (1). Said method comprises the following steps: fuel is injected for test purposes during the expansion cycle and/or the discharge cycle of the internal combustion engine (1); at least one portion ...
A method for testing the functional capability of a catalytic converter of an internal combustion engine uses an exhaust-gas probe having a measuring electrode for measuring the resistance of a metal oxide layer having low catalytic activity. The resistance of the metal oxide layer is dependent on...
There Must Be Another Way The easiest test requiring the fewest special tools is simply removing theoxygen sensoror loosening the exhaust pipe connection upwind of the catalytic converter. If you briefly run the engine with these disconnected (oxygen sensor) or loose (pipe) and the condition impro...
000 miles. However, there are many factors that can affect the lifespan of a catalytic converter such as the quality of the converter, the type of vehicle it’s in, and how well the vehicle is maintained. Many catalytic converters will last the life of the car, while others have a sche...

mode between target and converter in the traditional circuit, the generated double-end DNAzyme assemblies were in one-to-two conversion mode between target and DNAzyme in the conceived CHA circuit, which greatly increased signal gain and amplification efficiency in linear amplification. In ...
However, this strength of perovskite-type oxides can be a drawback when it reacts with the substrate, binder or primer materials that are present in a TWC converter. This leads to decreased TWC activity. In extruded catalysts, such chemical interactions are not a serious issue owing to the ...
