6.3. Operation of cars with the catalyst

The catalyst is a reliable and simple device which does not require any service, but there are some facts which the owner should know for the maximum service life of the catalyst.

Do not use этилированный gasoline in the car equipped with the catalyst as lead will cover precious metals in a catalyst lattice, reducing efficiency of their transformation and finally will put out of action the catalyst.

Always contain ignition and fuel system in a full order.

If at engine work ignition admissions are observed, do not maintain the car before malfunction elimination.

If at engine work the control lamp of engine management lights up, it is necessary to address as soon as possible on servicing deport. If there is an engine management damage except increase in the expense of fuel and reduction of dynamic characteristics of the engine, the catalyst can fail.

Do not start the engine a towage method.

Do not switch off ignition on high turns of the engine.

Do not use an additive to fuel and engine oil as additives can contain the substances, capable to damage the catalyst.

Do not use the car if from an exhaust pipe the trace of a dark blue smoke is visible.

After a stop of the engine an exhaust system long time continues to radiate heat significant amount, therefore it is necessary to avoid a car parking on a grass and dry leaves.

Remember that the catalyst is fragile, therefore avoid blows at catalyst or exhaust system removal.

The catalyst used on well adjusted car should serve from 100 to 160 thousand in km of run of the car.
