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?

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

Сlogged catalyst. How to complete a fast check up?

A clogged catalyst is a common malfunction in high mileage vehicles. Over time, a system breaks down that serves to reduce exhaust emissions. Usually the first signs of this condition are observed after 150 or 200 thousand km. But sometimes it can occur earlier if the engine is not properly operated or a manufacturing defect takes place. Today we’ll talk about the symptoms of a clogged catalyst. How to understand that catalyst is clogged and fix the problem? Signs of a clogged catalyst Classic symptoms of a malfunction are a decrease in dynamics of a car and a noticeable cut in engine power. As a result, the level of maximum speed decreases; the car accelerates sluggishly during overtaking or when starting at a traffic light. Additional signs which shows that catalyst is clogged or not:   Motor starts hard on both hot and cold temperature, a strange sound appears. Power unit may fail completely if the assembly is too clogged. Exhaust fumes start to smell

Five mistakes to avoid, cutting off car catalyst

Five mistakes to avoid, cutting off car catalyst Many people know that car catalytic converter must be removed mandatory, after a certain mileage! But they consider it as a useless piece of metal. Thinking that it costs nothing, knock it out to just throw it away! However, this is wrong, a catalyst can be sold for a good sum of money. There five general mistakes, regarding catalyst cutting off. Mistake 5. There is a maximum mileage, which requires obligatory catalyst cutting off There is no specific mileage to remove or throw away the catalyst. Everything is very individual and depends on many indicators, including the fuel that motor uses. It happens that bad quality gasoline can melt and destroy the catalyst and all the unit at a time. If you refuel with good fuel at proven gas stations, then the unit can work for a long period of time, for example 150-200 or even 250,000 km. Especially if this catalyst is of EURO3 or EURO4, the unit walls are thick and last longer. T

Catalyst vs. Flame arrester

Catalyst vs. Flame arrester The struggle of automotive engineers for environment has led to appearance of units that are not used for movement, but reduction of air pollution. Catalyst is one of them. A metal can with a ceramic honeycomb system "burns" exhaust gases inside and reduces the harmfulness of car exhaust. According to experts, you need to get rid of a catalyst after 150-200 thousand kilometers. It is for such a run that this node is designed. It’s better to do it as soon as fuel consumption starts to increase and the car starts to accelerate worse.   Removing catalyst and installing a flame arrester will cost much less than replacing catalyst itself. But removing of catalyst will increase toxicity of emissions, so this option is not suitable for people concerned about environmental safety of our planet.   But catalytic converter is not eternal, sooner or later the catalyst is clogged, its cells are destroyed, and it not only ceases to fulfill its functi

Prescious metals in a catalyst

Prescious metals in a catalyst In modern car there are a lot of interesting things. It turns out that there are even noble metals in it and the car owner himself can make good money with its help. Not everyone knows that the so-called exhaust system catalyst or rather, an exhaust gas catalyst contains precious metals of platinum group. First of all, it is actually platinum, as well as noble metals palladium and rhodium. A porous ceramic or metal filling is hidden in catalyst housing, where another noble metal is sprayed. Therefore, after the automotive catalyst fails and this usually happens after 150-200 thousand kilometers, you can take it to special processing companies, which are able to extract precious metal for recycling. The main nuance of this procedure is that platinum metals are in a form of a very thin layer sprayed onto porous ceramic cells. In fact, the device is conceived as such, so that the contact surface of exhaust gases with metal catalyst is as wide a

DIY catalyst cleaning

DIY catalyst cleaning Catalyst in a modern car is necessary to reduce exhaust emissions. This part has a limited resource, so over time it becomes necessary to replace and clean it. Catalyst, regardless of car model, is quite expensive. For this reason, many drivers are wondering how to clean the detail without replacing it. The unit is similar to resonator tank. Catalyst is a container with two connecting nozzles. Inside there are small ceramic honeycombs coated with a catalytic layer based on noble metals (hence the high price of spare parts). Exhaust flue gases clog the cells with soot, gradually making the neutralizer impassable. The option without dismantling is a priority for vehicle owners, because on many cars this part can be removed only by cutting the grinder from the exhaust gas system. Can DIY catalyst cleaning be effective? Before proceeding with actions, it is necessary to find out in which cases catalyst cleaning can bring benefit. Flushing the catalytic co
