Which catalytic converters have the most platinum

A platinum catalyst is used in many vehicles today. It is one of the main elements of the exhaust system and reduces harmful emissions. Catalyst's body is plated with precious metals, which, under certain conditions, can be extracted. However, it is difficult to predict in advance how much platinum is contained in a car catalyst. The fundamental design of catalysts has hardly changed since its inception, which cannot be said about manufacturing technologies. In recent years, thermal and aerodynamic performance has been particularly improved, resulting in improved neutralization and long-term stability. The main parts of every catalyst are housing and exhaust system made of stainless steel (expensive materials); special pads (protection and fixation for the ceramic block); support material or block (metal or ceramic); intermediate fixing layer for precious metals; catalytically active layer. The stainless steel body of a catalyst A stainless steel housing is required to provide g

Can catalytic converter be cleaned

To neutralize toxic gases emitted from an internal combustion engine, a catalytic converter is installed in a car. Catalyst Is located at the outlet of the exhaust manifold. Although the service life of every catalyst is about 150 thousand km, changing it is rather expensive. It is too expensive if you need to buy a new item. A natural question arises whether it is possible to clean this car part and thus extend its resource. The answer is simple: cleaning is permissible, but there is no guarantee of a positive result. The problem is widespread and deserves more detailed consideration. When should you clean your catalyst? The unit, which looks like a resonator tank, is a container with two connecting pipes. There are small ceramic honeycombs covered with a catalytic layer based on precious metals (hence the high price of a spare part). Exhaust flue gases clog cells with soot and carbon deposits, gradually making catalyst impassable. Cleaning or flushing the catalyst will give a

How catalytic converter reduce air pollution

Catalysts appeared just in the first half of the 70s and, as you know, US automakers were at the forefront here for a while. Curiously, in addition to directly reducing the toxicity of exhaust, these catalysts have dragged along with the modernization of several areas of development of the automotive industry. This was due to the very principle of their action, which, by the way, has not changed until now. For some time, and on different models, catalysts coexisted with carburetors or mechanical injection. For example, Chrysler, having burned itself with electronic fuel supply back in the 50s, was in no hurry to transfer its engines to it. But limiting norms for the content of various elements in the exhaust were approved by law. It was necessary to somehow link the catalyst and the carburetor. Ecology is the engine of progress. The metal barrel, located between the exhaust manifold and muffler-resonators, has a longitudinal honeycomb inside, where the surface is covered with a la

Will catalytic converter cause misfire

First of all, the catalyst is an essential part of a whole car, as well as ignition. Among many reasons for a malfunction of ignition, that can cause a misfire, the main ones are: Failure of catalyst elements of the ignition system. Armored wire, spark plugs, coil, or breaker-distributor. Also, at low temperatures in candle wells, condensation may form, which can cause "breakthrough" into a catalyst. Malfunctions in the fuel-air system can be associated with clogged dirt and deposits in injection nozzles, air and fuel filters. These ailments are manifested in the "triplet" of an engine at idle, which disappears after warming up. Low compression in all cylinders or its non-uniform distribution indicates wear of elements of a cylinder-piston group or malfunctions in the operation of gas distribution mechanism. The incorrectly adjusted valve can lead to a violation during the compression stroke of the tightness of the entire catalyst chamber. The lack of an optimal f

Can catalytic converter damage engine

Catalyst is part of the exhaust system and is located in the immediate vicinity of a vehicle's exhaust manifold. Catalyst enters into that incandescent exhaust manifold, and after that, significantly slowed down, cooled and cleaned of harmful substances, it appears in a resonator and in a muffler. The principle of operation of a catalyst is based on chemical reactions that neutralize harmful emissions of nitrogen oxide, carbon, and all kinds of hydrocarbon groups. The main element of a catalyst is made in a form of a massive ceramic or metal block with small honeycombs, on walls of which precious metals are applied: an alloy of iridium and platinum, as well as rhodium and palladium. When touching chemically active surfaces, harmful compounds are burned and removed from the exhaust pipe in the form of harmless N2 and CO2. Platinum and palladium act as oxidants in a catalyst and greatly accelerate the combustion of hydrocarbons. The active element is placed in a metal casing and provi

Can catalytic converter cause shaking

Very often, car owners are faced with the fact that vibration is felt in a car cabin, and often this is due to the exhaust system. Almost all cars have parts or connections that compensate for the vibrations of the engine, respectively so that they are not transmitted to the exhaust system and car body. This is either a damper connection or a muffler. Any inexperienced driver can easily identify a malfunction in the exhaust pipe, often associated with a catalyst. Signs of a clogged or destroyed catalyst malfunction The car does not start or stalls instantly. The catalyst indicates a complete breakdown. Solution: Unscrew oxygen sensor (located in front of the catalyst). Start the engine, if the car is working, then the catalyst barrel is faulty. It needs to be replaced with a new one or an analog. The car accelerates poorly and the engine picks up speed slowly. When driving, it seems that the car is being held from behind. So catalyst cells are partially clogged. Fuel

Сlean catalytic converter without removing

Every car catalyst is a container in which two connecting pipes are built. Usually, it also contains a miniature ceramic honeycomb with a catalytic layer applied. The high price of a catalyst is explained by the fact that this coating is made on the basis of precious metals. Exhaust gases can clog honeycombs with carbon deposits and soot, impairing the permeability of a catalyst. It is important to take care of car catalysts in advance, but many vehicle owners consider if it is possible to wash catalyst without taking off or cutting it off. Cleaning your vehicle's catalytic converter can be beneficial and extend its life in the following situations: If manipulation is carried out for prevention purposes, that is, before any problems appear. If there is no damage in cells, and soot is simply packed there. If the catalyst structure has not been melted due to the use of leaded gasoline. How to identify an urgent catalyst cleaning need? There are some signs which

Catalyst cost for different car brands

Why are car catalysts worth so much? Catalysts alone do not cost much if one thing is not taken into account. The design of this item costs no more than 150 USD for a best matrix and best metal. But main price is precious spraying, which includes platinum, white gold and many other dredges, metals that are oxidized, evaporated and mixed with exhaust gases during heating, eventually converting them into harmless gases. If not for this spraying, then any driver could afford to buy a new fresh catalyst. Unfortunately, the value of a brand and company that sells the product is still wound up on a production cost of a catalyst. As a result, such spare parts are very expensive, which of course affects the demand for this product. How to choose a catalyst? Should one buy expensive or cheap? You must always choose a catalyst for a car engine. The more powerful the engine, the better the catalyst should stand, for example, if you have Solaris, Focus, Fabia, then catalyst can be supplie

Engine power change after catalyst cutting off

Catalyst in a car serves to reduce toxicity of exhaust exhaust gases from the engine, but exhaust system element is often clogged by slag and fails. Usually owners want to improve vehicle performance like increased power, aestheticization and drive quality. Power has been achieved with an installed crankshaft with an increased radius of a curved cylinder, as well as with a variable camshaft or adding a high octane rating to gasoline, removing catalyst. It must be dangerous to increase power through tuning exhaust system. But this is one of the most affordable and productive methods of increasing power. Before trying it, consider all pros and cons. Consult experts of the industry and specialized companies. They will select, and possibly even compatible types of tuning of exhaust system to obtain best vehicle performance. There Is also chip tuning process, which involves changing engine programs and increasing productivity by 20-30%! Removing catalyst or replacing it with a f

Keep the catalyst. Don't cut it off!

Nowadays in the vastness of network, you can find many tips where motorists offer their less experienced colleagues to cut off the catalyst on a car. It’s time to figure out why this element of design was so annoying for some drivers, and why in fact it should be left in its place. The first and most important thing why unfortunate catalyst is so annoying for many motorists is its cost. And everything because the catalyst uses expensive platinum. That is why few people want to spend huge amounts on replacing catalyst. As a result, many drivers simply decide to remove the part, and install a flame extinguisher on its place in the muffler. On the one hand, this move is cunning and even somewhat reasonable (a slight increase in power). If only because if nothing is done with problematic element immediately, then it will be worse. On the other hand, it’s better not to do this at all. Firstly, it is necessary to clarify a simple truth that a car without catalyst become

Car catalyst functions and significance

Car catalyst is designed to neutralize harmful car exhausts and is part of exhaust system. A catalyst is an element of an engine exhaust system designed to clean exhaust gases before they are released into the atmosphere. The need to develop this automobile motor assembly arose in 60s of the last century, when the world community was concerned about the state of ecology on our planet. At that time, the level of emissions from automobile exhaust pipes was not established at legislative level. The first standards for content of toxic products in car emissions were introduced in 1970s. Auto producers were required to equip cars with devices that reduce volume of carbon monoxide and products of combustion of hydrocarbons. Since 1975, catalyst has become an indispensable part of all cars coming off the assembly line. Manufacturers install three types of catalysts on cars: Ceramic item use a mechanical method of cleaning exhaust gases. It consist of ceramic plates coated with
