The emission reduction device in a car is a device that plays a key role in the system of exhaust gas purification from harmful substances. The main task of the catalyst is to reduce the content of nitrogen oxides, hydrocarbons and carbon monoxide in the exhaust gasses, which are formed during combustion of fuel. These harmful substances are atmospheric pollutants and are serious contributors to smog and climate change.
The system is a mandatory part of modern automotive emission control systems and is an important element in improving the environmental performance of vehicles. But if this part in your car has fallen into disrepair and you are planning to remove the unit, we recommend selling it on the Autocatalyst platform. On the site https://autocatalystmarket.com/us/en/models/nissan-pathfinder there is always a lot willing to buy a used catalytic converter from various models of Nissan and a large number of other brands.
Features of work
The emission reduction device is usually installed in the exhaust system of the car, directly after the manifold or exhaust manifold, where it can maximize the effect on the exhaust gasses. It consists of a ceramic block coated with special catalysts such as platinum, palladium and rhodium.
The process of catalyst operation is based on catalysis – acceleration of chemical reactions without independent participation in them. Basically, it acts in two ways: oxidation and reduction.
Symptoms of catalyst overheating
Symptoms of overheating most commonly involve the following:
- Increased fuel consumption. If the catalytic converter overheats, it may consume more fuel than normal. This can be caused by the catalyst not being able to perform its function properly, causing the engine to run less efficiently.
- Unpleasant odor. When the emission reduction device overheats, an unpleasant odor that resembles rotten eggs can occur. This happens because the catalytic converter cannot properly process the exhaust gasses, resulting in the formation of hydrogen sulfide.
- Loss of power. Another symptom of an overheated catalytic converter can be a loss of engine power. The emission reduction device can become clogged due to a buildup of contaminants, resulting in poor gas flow.
Elevated exhaust temperatures pose a potential concern. The detection of excessively high temperatures in the exhaust gases may signify an overheating issue with the catalytic converter. Such heightened temperatures not only pose risks but also have the potential to inflict harm on other integral vehicle components.
To avert the risk of overheating in the emission reduction device, it is prudent to maintain the engine and exhaust system in optimal condition, ensuring regular servicing. Additionally, adopting a cautious approach, refraining from abrupt acceleration and deceleration, and opting for extended journeys when feasible, contribute to sustaining the peak performance of the neutralizer.
Prompt attention to any observed symptoms is strongly advised, prompting the engagement of professional assistance for a thorough diagnosis and resolution. Neglecting signs of an overheated converter may result in severe damage, translating into substantial expenses for vehicle repairs.
