Apparatus, method and system are provided for monitoring catalytic converter efficiency in treating exhaust gas from an internal combustion engine. The air/fuel ratio fed to the engine is perturbed on a cylinder-to-cylinder basis above and below a mean or average air/fuel ratio. The signal from...
The conversion rate of a catalytic converter has an effect on the oxygen partial pressure in the exhaust gas downstream of the catalytic converter, so that the resistance of the metal oxide layer depends on the conversion efficiency of the catalytic converter. It is thus possible to test the ...
The effects of the air‐fuel (A/F) ratio and spark timing on exhaust emissions and thermal efficiency were analyzed under part load conditions using an ethanol‐fueled spark ignition (SI) engine. The conversion efficiency of exhaust emissions after the application of a three﹚ay catalyst (TWC)...
The article deals with the efficiency of the catalytic converter of automobiles in operation with the aim of solving the problem of reducing the pollution of the atmospheric air by the exhaust gases of automobiles. The problem of reducing emissions of harmful substances of vehicles is considered to...
Converter aging/lack of engine maintenance - cycles of damaging engine conditions will eventually deteriorate converter performance. Q: Why is my "Check Engine" or "MIL" light indicating that I have a "P0420 Low Converter Efficiency" code; does this mean the converter needs to be replaced? A...
For the on-board diagnosis of the catalytic converter for SI engine, the comparison between upstream and downstream catalyst lambda signals is used to derive information about the actual conversion efficiency. In the present work three indices have been computed by means of both deterministic and sta...
