Security measures for an exception of damages of the catalytic converter

For an exception of damages of the catalytic converter it is necessary to fulfill the following requirements:

Petrol engines

- Apply only unleaded gasoline.
- Start of the petrol engine by pushing or towage is authorized to carry out only from one attempt and at distance no more than 50 m. Better for this purpose to apply an auxiliary cable. Not burned down fuel at ignition can lead to an overheat of the catalytic converter and its destruction. If the engine is heated-up, start by its pushing is not allowed.

- At difficulty with start of the engine it is not necessary to include a starter too long. Continuous injection of fuel is thus made. It is necessary to reveal and eliminate a cause of defect.
- Never spend fuel in a fuel tank completely.
- At emergence of interruptions in ignition do not raise number of turns of the engine and immediately eliminate malfunction.
- Apply only resolved BMWs of a spark plug.
- Do not inspect spark existence with the disconnected tip of a spark plug.
- Do not inspect operation of cylinders by shutdown of ignition of any cylinder. At shutdown of any cylinder not burned down fuel gets to the catalytic converter.

Petrol and diesel engines


- Do not stop the car over dry foliage or a grass. The system of production of the fulfilled gases around the catalytic converter very hot also radiates heat even after an engine stop.
- Do not put on elements of system of release of means for protection of the bottom of the car.
- Do not change a design of heat-shielding screens.
- When filling engine with oil especially pay attention to exceeding at all the level designated on the index as by Max. Excess of oil owing to incomplete combustion arrives in the catalytic converter and can damage its covering from the alloyed metal or completely to destroy the catalytic converter.
