FAQS
1. What are catalytic converters for gasoline and diesel cars?
A catalytic converter is a device installed in a car's exhaust system to reduce emissions of harmful gases, such as carbon monoxide, nitrogen oxides and hydrocarbons.
2. What is the difference between the catalytic converters of gasoline cars and diesel cars?
The catalytic converter of gasoline vehicles mainly converts harmful gases into harmless substances through oxidation and reduction reactions. Diesel catalysts usually include oxidation catalysts, particle traps and selective catalytic reduction systems to deal with different pollutants produced by diesel combustion.
3. How often does the catalytic converter need to be replaced?
This depends on a variety of factors, including the vehicle's age, mileage, fuel quality and driving habits. In general, under normal use, the gasoline car catalytic converter can be used for 8-10 years, and the diesel car catalytic converter may require more frequent inspection and maintenance.
4. How to judge whether the catalytic converter is damaged?
Common signs include decreased vehicle power, increased fuel consumption, abnormal exhaust odor, fault indicator light, etc. Professional testing equipment can more accurately judge the condition of the catalytic converter.
5. What is the impact of catalytic converter damage on vehicles and the environment?
For vehicles, it will lead to performance degradation, excessive emissions, and may not pass the annual inspection. For the environment, it will increase the emission of harmful gases and aggravate air pollution.
6. How to maintain the catalytic converter?
Use high-quality fuel and oil, avoid prolonged idling, carry out regular vehicle maintenance and inspections, and deal with engine failures in a timely manner.
7. How much does it cost to replace the catalytic converter?
Prices vary by model, brand and market. The cost of replacing the catalytic converter of gasoline vehicles usually ranges from several hundred to several thousand yuan, and the cost of diesel vehicles may be higher due to the more complex technology.
8. Is it feasible to install non-original catalytic converters?
It is recommended to use catalytic converters that are original or meet quality standards to ensure their performance and reliability, and informal products may not be effective in reducing emissions.
9. Is the catalyst fault covered by the vehicle warranty?
Depending on the warranty policy of the vehicle and the cause of the failure, the failure due to manufacturing defects can be repaired or replaced free of charge during the warranty period.
