Volvo S40 T5 For Sale From UK At Reasonable Price
Catalytic Converter In The Volvo S40 T5 For Sale Has Lots Of Tiny Channels
The definition of a catalytic converter means a catalytic converter inserted in the exhaust system, or a device capable of initiating or promoting a chemical reaction inside it. So, a buyer who is in search of buy the Volvo s40 t5 for sale should know that this converter has a ceramic or metal body with a specific structure, with hundreds of tiny channels.
In Between
The walls are covered with a thin film that has as its main components catalyst metals, such as platinum, palladium, and rhodium. Its diffusion on the European car market became massive in the first half of the 90s. The catalytic converter sees the converter positioned between the exhaust manifolds and the first silencer. When the gases that come out of the combustion chamber flow into the converter and pass through its multiple interstices, the metals that cover the walls give way to reactions that transform them. The catalytic converter can be of two types such as oxidizing or trivalent. The first type is used on diesel engines and transforms carbon monoxide into carbon dioxide and oxidizes unburnt hydrocarbons; the second is the most advanced and effective since it also reduces nitrogen oxides and is developed for petrol, LPG or methane engines.
The Various Types
To treat NOx on newer diesel, further specific catalysts are needed, which are of two different types, called Lnt and Scr. Anyhow, for the converter to perform its task properly, it should work at a high temperature and is therefore not very efficient when cold, when the engine has just been started. Each engine requires a dedicated catalyst, sized based not only on the type of engine and the fuel used but also on the basis of other factors, such as power, gas flow rate and maximum allowable back-pressure. Besides, before pay the Volvo s40 t5 price, a used car buyer needs to know that the catalytic converter has the task of chemically transforming substances harmful to health and the environment present in the exhaust gases into harmless elements or compounds or in any case with a minor negative impact. In a marginal way, the catalytic converter also helps the silencer to reduce noise.
To be Precise
In other words, it can be stated precisely that the catalytic converter is a device incorporated in the exhaust system of an automobile which reduces the amount of pollutants in its exhaust gases. It contains a ceramic element, with a structure, coated with a thin film of catalyst metals such as palladium, rhodium and platinum. When the exhaust gases pass through the catalytic converter, these metals favor chemical reactions that transform pollutants, such as carbon monoxide, nitrogen oxides and certain hydrocarbons, into harmless compounds such as carbon dioxide nitrogen and water. Please note that the discussed aspects are precise; hence, a used car buyer need to extract all relevant aspects when he wants a reliable drive. In addition, cars equipped with this device should use unleaded petrol since otherwise the catalyst metals would be covered with lead and would cease to function properly.
