The cause of "Catalytic Converter" jammed

One of the major diseases catalytic converter or catalytic converter ( CC ) have great influence on the performance of the engine when the catalyst is functioning as it melted and clogged filter . When compressed , the engine exhaust gas can not flow properly causing back pressure . The next result , engine power output so lousy aka lackluster . Such conditions often cause the driver presses the accelerator pedal getting deeper. As a result, fuel consumption is so wasteful !

maintenance
In the first stage when CC is used in diesel engines in Indonesia (2007-2008) , the driver often complained that , at a certain distance , lousy engine power output . The APM technicians generally proposed , to solve it , the vehicle must be accelerated to a maximum rotation as far as 1 km to push dirt in CC . On the other hand , they do not analyze the real causal factors , for example , fuel quality , settings , and conditions of the engine components .

Various cases in the world , including the analysis of the producer company , shows that the CC incompressible because the machine works with the fuel mixture is too rich . As a result , many hydrocarbons ( HC ) or unburned fuel is in the catalyst . In this condition , the higher the temperature of the catalyst . If continued , the catalyst may melt . The melt clog tiny holes that serves as a catalyst filter .

Fuel mixture is too rich can also occur due to problems in the injector , or the oxygen sensor , or also due to incorrect ignition ( petrol engine specifically ) . Oxygen sensor plays an important role in this regard . Because these sensors constantly monitor the composition of the exhaust gas oxygen produced ( to determine the composition of the mixture ) , and then sent to the engine computer . Next, set the engine computer , whether to reduce the dose of the amount of fuel that is sprayed or add to it ( based on the old injector opening ) . Therefore, it is important to maintain and inspect the condition of the sensor .

Actually , the problem of clogged CC rather rare today because gasoline is used no longer contain lead or lead ( Pb ) . If anything , the numbers are very small. Alternatively, the substance that makes for other materials , such as fuel additives . Therefore, do not use any additives .

another possibility
Another CC damage is partly because his house cracked ( hit a rock ) , mounting bolt is not good, or poor-quality home materials ( cracks and change shape when high heat ) . Conditions that can damage engine components CC include piston rings wear out ( the oil flow to the combustion chamber ) and the results are less good injector spray ( low pressure at the injector or fuel pump ) .

Electrode spark plugs are dirty or have been eroded also lead to sub-optimal combustion , HC or more leaves . Alternatively, the exhaust gas recirculation valve ( EGR ) is not working properly , or engine valve seals , cylinder head gaskets , and broken suction channel .

The cylinder head is warped with the most common indication , still easy to " fever " aka overheat , also causing CC can not work effectively . Even then , if the use of glue or mechanical seals made ​​from Teflon and silicone when opening the machine and put it back ( when disassembled ) , then it will bring up a new terror , not only for CC , but also the oxygen sensor !
