Cars with gasoline engines
1 - Catalytic converter of exhaust gases
A catalytic converter is part of the emission control system. Its job is to remove some of the combustion products from the exhaust gases. It looks like a muffler and is installed under the car in the exhaust system.
Diesel Engine Cars
Hyundai vehicles are equipped with oxidizing type catalytic converters for exhaust gases to reduce the concentration of CH, CO and NOx in exhaust gases.
Information about the catalytic converter
The exhaust gases passing through the catalytic converter heat it up considerably. As a result, the entry of a large amount of unburned fuel can lead to its ignition.
This can be avoided by following these rules:
- Use only unleaded gasoline.
- Keep the engine in good technical condition. Excessively high catalytic converter temperature can cause improper operation of the electrical system; ignition or fuel injection.
- If your engine stalls, makes noise, knocks, or is difficult to start, take your vehicle to an authorized Hyundai dealer immediately to have the problem corrected.
- Do not drive the vehicle with very low fuel levels. Running out of fuel can cause misfiring and overload the catalytic converter.
- Do not allow the engine to idle for more than 10 minutes.
- You should not start the engine of your HYUNDAI car by towing it. This may cause damage to the exhaust gas catalytic converter.
- Do not touch the catalytic converter or other exhaust system parts while the engine is running, as they become very hot and can burn you. Turn off the engine and wait at least one hour before touching the catalytic converter or other exhaust system parts.
- Have your vehicle serviced regularly at an authorized Hyundai dealer.
- Avoid parking in areas where hot exhaust system components may come into contact with flammable materials or objects, such as dry fallen leaves or grass. This could cause a fire.
Exhaust Gas Recirculation (EGR) System
This system helps reduce nitrogen oxide emissions by directing a portion of the exhaust gases back into the combustion chamber to lower the temperature inside the combustion chamber.
