Types of catalytic converters
Types of catalytic converters
The structure of cars has changed over the past decades. The use of new technologies is aimed at not only improving the comfort of their users, but also to minimise their negative impact on the natural environment.
An element of the exhaust system, which is to reduce the emission of harmful exhaust fumes coming from the engine, is the car catalyst. What types of catalytic converters are there and what are their basic functions?
Where is the catalytic converter located in the car?
Basic knowledge of the structure of elements in the car gives us the opportunity to identify problems related to its functioning early. The diagram of structure of a car catalyst is relatively simple as it consists of only a few elements.
The most important part - the core - is covered with one of the noble metals, such as rhodium, palladium or platinum. Another element is the protective part that seals and insulates the core. The whole thing is surrounded by a housing made of stainless steel, which prevents corrosion of the catalytic converter.
Where is the catalytic converter located in the car? This element is the part of the exhaust system in which the toxicity of the exhaust fumes from the engine is reduced. After the harmful fumes are filtered, they go to other parts of this system to finally get out into the atmosphere. Due to the activity of noble metals included in the car catalyst, the harmfulness of chemical compounds formed during engine operation is reduced.

Types of catalytic converters
Taking into account reactions taking place in them The type of engine has a direct influence on the types of catalytic converters.
The type of fuel we use to power our cars is directly related to the catalytic converter in the exhaust system. In compression ignition internal combustion engines operating on diesel fuel, oxidizing catalytic converters are used. The catalytic converter in petrol engines differs from those used in diesel engines.
Cars with a spark ignition engine, in the vast majority of cases, have three-way catalytic converters. In this type of catalytic converter, both oxidation and reduction reactions take place. A car catalyst in the exhaust system of internal combustion engines can be made of two types of monoliths: ceramic and metal.
