Symptoms of clogged exhaust system

Clogging of the catalyst can be determined by the work of the engine on very apparent hissing sound coming from under the car, in addition, putting a hand to the end of the exhaust pipe, you can test the strength of the exhaust and the degree of clogging the system. On the performance of the catalyst shows a high temperature of exhaust gases and copious steam and water droplets at the outlet of the pipe. The temperature of the gas at the outlet of the pipe can be checked with his hand, being careful. If the exhaust system has an oxygen sensor or a measuring tube for CO gas analyzer, in this case, we can accurately measure the loss of the exhaust system. Manometer to 5 kg / cm is connected via an adapter instead of the oxygen sensor or vykruchennogo to measure the CO tube. Under normal conditions, the catalyst life of about 60 000 km. Serious damage to the catalyst can occur only if it is misuse. Running the engine with intermittent ignition or enrichment of the mixture lead to overheating and melting of the catalyst that makes the cork in the exhaust pipe. If you do not want to buy a new catalyst that can knock out the old. Knockout of the catalyst should be complete, since the remaining tube into small fragments of ceramic element can clog the following passages in the killing. When clogged exhaust system spark plugs will always be black because of the deterioration of the combustion process of the working mixture.
