That's why:
- Rolling, moving, or towing is not a problem if the starter will not start the engine due to a dead battery.
- Towing over long distances - which, for example, can be with a defective ignition - is unacceptable, because. a large amount of unburned fuel enters the exhaust system, which is especially harmful when the catalytic converter is still cold.
- If interruptions or defects in the ignition allow us to conclude that there is a malfunction in the ignition system, then it should be checked immediately (In workshop). During a long trip, avoid high engine speeds.
- When the engine is running for a long time at full gas supply, there can also be no overheating of the catalytic converter, because. the increased gas flow has a cooling effect on the catalytic converter to a certain extent. Its middle is much hotter due to «residual combustion», than the temperature of the exhaust gases ejected from the engine.
Besides:
- In the height of summer, after a long drought, do not park the car on dry leaves, hay, etc., when parking. Under particularly unfavorable circumstances, this may cause a fire under the car.
- If necessary, check with the vehicle raised for damage or missing heat shields.
What else do you need to know:
- Additives in fuel and engine oils do not harm the catalytic converter. And you can be completely sure of this if the working substances are approved by Opel.
Lambda probe assembled and in section. The numbers indicate:
1 - probe heating connection;
2 - heating rod;
3 - probe ceramics;
4 - protective tube;
5 - supporting ceramics.
Defects in the catalytic converter or lambda probe can be detected as a result of an exhaust gas test. A catalytic converter with thermal damage is recognized by a knock. The ceramic body of the catalytic converter is compressed by partial melting, which leads to its free movement in the metal shell.
Tip: Sometimes cars with a catalytic converter attract attention with a strong smell. A bad odor is emitted by trace amounts of the sulfur compound H2S (hydrogen sulfide), that may form in the catalytic converter. This poisonous substance - in the concentration that is found in the car, is completely harmless. Help: missing. For the sake of experiment, fill up at another gas station in order to find fuel with a lower sulfur content.
