8.10. Catalyst


Removal of the catalyst together with the exhaust system from under the car
 

In the presence of damages or dents on the case of the catalyst it needs to be replaced

It is periodically necessary to check that there is a sufficient air gap between thermoprotection by the ny screen and the catalyst

The catalyst – the reliable and simple device which does not need in any service, but there are some facts which the owner has to know for the maximum service life of the catalyst:

– not to use ethylated gasoline in the car equipped with the catalyst as lead will cover precious metals in a catalyst lattice will reduce efficiency of their transformation and eventually, will put the catalyst out of action;
– always you keep ignition and fuel systems in a full order;
– if during the operation of the engine admissions of ignition are observed, do not operate the car before malfunction elimination;
– do not start the engine by a towage method;
– do not switch off ignition at high frequencies of rotation of the engine;
– do not use the car if from an exhaust pipe the trace of blue smoke is visible;
– after an engine stop the exhaust system a long time continues to radiate a significant amount of heat therefore it is necessary to avoid the parking of the car on a grass and dry leaves;
– you remember that the catalyst is fragile therefore avoid blows at removal of the catalyst or exhaust system;
– the catalyst used on well adjusted car has to serve from 100 to 150 thousand km of a run of the car.
