Does Your Nissan Need a New Catalytic Converter?

Catalytic converters were invented to help combat the issues of climate pollution caused by car emissions. These days, this part is an expected inclusion in your fuel system and is required for everything to run smoothly. Like all equipment, this piece can become damaged from age and use. Before you visit your Nissan dealer, read through this list and determine if your converter is due for an update.

1. How Converters Function

Just as the name indicates, the purpose of a converter is to intake harmful materials and convert them chemically to less toxic molecules. The device contains a ceramic base with a honeycomb layer of metal mesh with two openings, one for intaking exhaust gases and one for releasing through the tailpipe. The mesh is made with precious metals, often something like gold or palladium, that performs as a catalyst.

The main pollutants converted are nitrogen oxides, hydrocarbons, and carbon monoxide, which are dangerous to inhale. Once chemically converted, these materials will exit the exhaust as water, air, or less harmful molecules. While some amount of pollutant may still remain, the overall benefits strongly outweigh the minimal effort of including a converter.

2. The Reason for the Mandate

With vehicle ownership having grown in popularity, the number of emissions created increased as well. Prior to the converter’s invention, citizens observed an increase in smog around cities with accompanying asthma-like symptoms, acid rain, and reports of damage to the atmosphere. The converter was made to manage emissions so that we can have all the benefits of vehicles without the downsides.

3. Signs Your Converter is Ready to be Replaced

The sign most people notice first is their tank emptying faster than before. This is because an aged converter will often become clogged, resulting in poor airflow through the fuel system. Without the ability to intake fresh air, the engine will not be able to reach a proper fuel-air mixture and gas will be sprayed without actually being used. This issue will also become apparent through reduce horsepower, as the vehicle will struggle to accelerate as it normally would.

Another obvious sign is hearing unexpected sounds from beneath the vehicle, especially when first turning on the engine. The noise will sound like a metal rattling and is caused by the film within the converter breaking loose and bouncing within the casing. Another sound-based indicator would be if the engine is exceptionally loud, which can indicate a total loss of the converter. In this instance, the engine will reach a shocking volume even when idle.

With a clean and fully functioning converter, your vehicle will manage better acceleration with improved fuel economy. On top of the benefits to you, keeping this piece operational also keeps everyone around your vehicle safe. Visit Nissan of Picayune today and upgrade your converter to keep your fuel system in its top condition.
