Security measures for an exception of damages of the catalytic converterFor an exception of damages of the catalytic converter it is necessary to fulfill the following requirements:
- Apply only unleaded gasoline.
- Start of the petrol engine pushing or towage is allowed 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. At the same time the continuous injection of fuel is made. It is necessary to reveal and remove a cause of defect.
- Never spend fuel in a gasoline tank completely.
- At emergence of interruptions in ignition do not increase the speed of the engine and immediately eliminate malfunction.
- Use only the resolved spark plug BMWs.
- You do not carry out verification of a spark with the disconnected spark plug plug.
- You do not carry out an inspection of 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.
- You do not apply 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 the engine with oil especially pay attention to not to exceed the level designated on the index as Max at all. Excess of oil owing to incomplete combustion comes to the catalytic converter and can damage its covering from the alloyed metal or completely destroy the catalytic converter.
