To reduce harmful toxic emissions by burning fuel in the exhaust system of motor transport provides for the installation of a device such as an automotive catalyst. What is it? If we talk in chemical terms, a catalyst is a substance that accelerates chemical reactions but at the same time it does not react. The main catalysts are the metals: Nickel, rhodium, copper, chromium, palladium and gold. The basis of the principle of operation of automobile catalytic device is the ability of catalytic materials to accelerate the chemical reactions.
Set automotive catalyst on the exhaust pipe right after the exhaust manifold, at least on the manifold. This is due to the working temperature parameters of the device, which works much better at three hundred degrees. The Disadvantage of the location is the short life of the catalyst, due to the high temperature.
In the process of fuel combustion in the cylinders of the engine in the exhaust gas are formed harmful and toxic substances. However, they adversely affect the human body and nature as a whole. The main harmful components include: hydrocarbons (the main component of the exhaust), nitrogen oxide (an optional component of exhaust gases), carbon monoxide (poisonous gases, odour and color).
As a rule, modern the catalyst is a three - component device type. And so it is equipped with converters in the amount of three pieces, each of which reduces the emissions of a certain substance. Part of a car is a metal flask, made of stainless steel, which is placed inside a number of hundred or ceramic beads.

The Honeycomb catalyst made of metal or ceramic material and have a catalytic coating substance. Mainly used for the deposition of rhodium, platinum and palladium. At the moment, were more likely to apply for the deposition of gold because it is cheaper than other materials for such parts as automotive catalyst. What is the design of ceramic? She has more common due to its cheapness, but it has one drawback-fragility. Enough minor impact to cell damage. Overcoming great irregularities of the roadway or obstacles such as the kerb, may damage the item. Thus drivers often do not notice the fact of damage to the catalyst.
The Converter uses two types – substances reducing and oxidizing properties (both are installed on the automotive catalyst). Precious metals, deposited on a honeycomb, have a restorative property. These are rhodium and platinum, which reduce emissions of nitrogen oxide. This process occurs as follows: at the time of collision of the molecules of dioxide or nitrogen oxide molecules of platinum separates nitrogen atom and the release of oxygen. Further, the nitrogen atom collides with another atom of nitrogen creates a nitrogen gas condition.
Oxidative stress is due to the use of palladium. In turn, this reduces the amount of catalyst is not gogolevskogo fuel and carbon monoxide in the exhaust gases by the method of incineration. In addition, this catalyst promotes the formation of carbon dioxide after the reaction between nitric oxide and oxygen that didn't burn. Simply put, as a result of these reactions, the harmful substances are burned and converted into water, carbon dioxide and nitrogen.
Depending on the design and materials used, the catalysts have their own characteristic lesions and contribute to the failure reason.
Ceramic type:
Additional types of devices:
The fact that the car is faulty automotive catalyst synth, motorists agree to one, and usually very similar. First, it is the other sounds in the body, which suggests that cell parts have mechanical damage. The following is a significant drop in performance engine car and its unstable work at idle. There's also the possibility of strong overheating of the device due to clogged SOT and bad bandwidth exhaust.
Often defective replaced with a new catalyst. To repair device is not possible, and if we try to restore it, it will be quite difficult and costly. However, hisperformance will drop significantly. To a new automotive catalyst price depends on the brand and model of machine. If we consider a standard budget auto catalysts, they can achieve prices of up to 15 thousand rubles including installation.
Basically, the warranty on this product is small. According to dealers, there are many factors that affect the duration of operation of the device and cannot be controlled. Automotive catalyst, the composition of materials which has high cost, is a complex structure in terms of manufacturing and can not be low cost. Therefore, there are several options for the replacement of damaged catalyst, which can offer you a HUNDRED:
This device is a conventional fuel filter collapsible type, comprising two interchangeable parts, cartridges. Sets the synthesizer catalyst in a fuel system of the engine of a car. To establish a catalytic process cartridge is mounted at number one, that works within twenty minutes. Then in its place is mounted the second cartridge, which carries out the process of the catalyst for ten thousand kilometers of the car. The process then alternately install the cartridges again. As a rule, the working life of the device is about thirty changes of cartridges or two hundred thousand mileage.
Automotive synthesizer catalyst has many positive effects on the engine operation:
The Acquisition of such a device will help to save costs during operation of the vehicle, what you say positive feedback from the drivers. Automotive synthesizer catalyst has a cost in the region of three and a half thousand rubles, but it all depends on the quality and manufacturer of the product.
Due to the fact that the design of the device provides for the use of expensive metals, and the item itself has a significant cost. Now there are many formal companies that are engaged in reprocessing devices. Recycle automotive catalyst – what is it? At the heart of this phenomenon is the process of obtaining the precious metals in the cells. There are several ways of processing, but they are all quite complex and time consuming, so extract the same platinum at home impossible. The Best option is to sell the device processors. Recycling of automotive catalysts in the enterprises is carried out in accordance with all regulations and requirements of environmental standards with the use of special manufacturing technologies.
Based on the foregoing, it is safe to note that such a device, as a catalyst, has a special significance, both for the full operation of the car, and for the environment. It is therefore necessary to monitor its condition and to carry out timely replacement in case of breakage of this part.
