Top 10 Questions for Catalytic Converter Operator Helper Interview

1. Explain the purpose and working principle of a catalytic converter?

• Catalytic converters are devices that reduce harmful emissions from internal combustion engines by converting them into less harmful substances.
• They work by using a catalyst to speed up the chemical reactions that convert unburned hydrocarbons and carbon monoxide into carbon dioxide and water.

2. Describe the different types of catalytic converters and their applications?

Three-way catalytic converters:

• Used in gasoline-powered vehicles.
• Reduce emissions of hydrocarbons, carbon monoxide, and nitrogen oxides.

Two-way catalytic converters:

• Used in diesel-powered vehicles.
• Reduce emissions of hydrocarbons and carbon monoxide.

Selective catalytic reduction (SCR) systems:

• Used in diesel-powered vehicles to reduce nitrogen oxide emissions.
• Inject urea into the exhaust stream to convert nitrogen oxides into nitrogen and water.

3. What are the common problems that can occur with catalytic converters?

• Clogging due to soot or debris.
• Melting or damage due to overheating.
• Poisoning by lead or other contaminants.

4. How can you troubleshoot and diagnose problems with catalytic converters?

• Check for visible damage or clogging.
• Measure exhaust gas temperature and pressure.
• Use an OBD-II scanner to retrieve diagnostic trouble codes (DTCs).

5. What are the safety precautions that should be taken when working with catalytic converters?

• Wear appropriate personal protective equipment (PPE), including gloves, safety glasses, and a respirator.
• Allow the catalytic converter to cool down before handling it.
• Avoid contact with the catalyst material.

6. Describe the role of oxygen sensors in the operation of catalytic converters?

• Oxygen sensors measure the amount of oxygen in the exhaust gas.
• This information is used by the engine’s computer to adjust the air-fuel mixture to ensure optimal performance and emissions control.

7. What are the environmental benefits of using catalytic converters?

• Reduce air pollution by converting harmful emissions into less harmful substances.
• Improve air quality and reduce the risk of respiratory problems.
• Contribute to cleaner air and a healthier environment.

8. What are the different types of catalysts used in catalytic converters?

• Platinum
• Palladium
• Rhodium

9. How can you extend the life of a catalytic converter?

• Use unleaded gasoline or diesel fuel.
• Avoid over-revving the engine.
• Have the catalytic converter inspected and serviced regularly.

10. What are the consequences of operating a vehicle with a faulty catalytic converter?

• Increased emissions of harmful pollutants.
• Reduced engine performance and fuel efficiency.
• Potential violations of emissions regulations.
