Catalytic converter (1.6 and 2.0L engines) (Nissan Sunny B13)

The catalytic converter is a reliable and simple device that does not require maintenance.

However, there are facts that a vehicle owner should be aware of if he wants the catalytic converter to function properly throughout its service life.

Do not use gasoline containing tetraethyl lead to fuel a vehicle with a catalytic converter - the lead will coat the precious metals, reducing their efficiency and, over time, causing the converter to fail.

If the engine starts to misfire, do not drive the vehicle (or manage as little as possible), until you eliminate the source of the problem.

Do not attempt to start the engine by pushing or towing the vehicle, as this will cause unburned fuel to enter the catalytic converter, causing it to overheat after the engine starts.

Do not switch off the ignition when the engine is running at high speed, i.e. do not press the accelerator pedal immediately before switching off the ignition.

Do not use fuel or motor oil additives. They may contain substances harmful to the catalytic converter.

Do not drive your vehicle if the engine is burning oil so much that blue smoke is visible.

Remember that the catalytic converter operates at very high temperatures. Therefore, do not park the car in tall dry grass or on a pile of dry leaves after a long drive.

Remember that the catalytic converter is very fragile. Do not hit it when repairing the car.

In some cases, a sulfur smell may come from the exhaust pipe (rotten egg smell). This is common in new cars that have a catalytic converter. After a few thousand kilometers, the smell should disappear.

A catalytic converter on a vehicle that has been regularly serviced and driven properly should last between 80,000 and 150,000 km. However, if the catalytic converter loses efficiency before this time, it must be replaced.
