Ford Focus>> System of production of the fulfilled gases>> The fulfilled gases>> Working temperatures in catalytic converter
Working temperatures are of great importance for service life of the oxygen sensor and catalytic converter. To too high temperatures react both the oxygen sensor, and the catalyst too sensitively. For example, when not burned down remains of a working mix ignite in the catalyst (interruption in ignition system), the internal temperature can reach dangerous level. Long influence of temperatures to 1200 ° With much reduces catalyst service life, and at temperature 1400 ° With its ceramic case and the oxygen sensor also melts overheats. You can find the melted catalyst on the characteristic hissing sound of the exhaust gases caused by increased resistance to pass of gases. Establish the reason quicker and eliminate it.
