Search for Catalytic converter :

Every day millions of cars go on streets. And each of them is a source of air pollution. This is relevant especially for big cities and metropolitan areas in which the exhaust gases emitted by vehicles cause a big problem. In today's world there is a device called catalytic converter, or simply, catalyzer. In all vehicles, the catalyzer is located in the silencer in order to purify exhaust gases.

The catalyzer is a component of the car`s exhaust system and is designed to burn the exhaust mixture in order to make it clean. In fact, the catalyzer has a fairly simple construction, but its effect it is very large. The catalyst is located either on the receiving pipe, or immediately after it. Inside the case there is a fixed honeycomb structure construction, which is made of metal or ceramic. Cells are necessary in order to increase the contact area of the exhaust gases with the sheet covered with a layer of platinum-iridium alloy.

The composition of this coating contains such expensive metals as rhodium, palladium and platinum. Unburned residues (CO, CH, NO) touching the surface of the catalyst bed, are finally oxidized by oxygen, which is also present in the exhaust gases. In the end, heat is generated, warming up the catalyzer, thereby activating the oxidation reaction. In the end, a correctly working catalyzer will emit exhaust gases with a permissible CO2 concentration.

In our online store you can buy a new, high quality catalyzer for any car brand. You don`t have to waste your time for shopping and repair centers. You can order the necessary part directly from your home or office. We will deliver it as soon as possible to any convenient place. Apart from catalyzer, you can order any other replacement part, such as drive clutch control cable, engine hood, fuel level indicator or condenser.

What is necessary to know about catalytic converter replacement: lifetime limits, common defects and their signs, tips and recommendations

Catalyst of exhaust gases has no specified lifetime limit, however specialists recommend to check its condition every 160 000 – 200 000 operational kilometers. Usually, replacement of the catalytic converter is necessary due to burning-out, clogging, mechanical damages of the ceramic honeycomb structure, and corrosion, mechanical or thermal damages of the housing.

Lowered engine power, unstable power plant operation, worsened  car dynamics, increased fuel consumption, excessive noise level from the exhaust system indicate that the exhaust system catalyst should be replaced. Burnt smell in the passenger compartment is also probable. Moreover, the “Check Engine” indicator may activate.

Today, most cars are equipped with the self-test system, which helps to control condition of the catalytic converter. If errors are found in unit operation, corresponding indicator activates on the dashboard. Detailed computer diagnostics of the exhaust manifold catalyst is performed at a service station.

Demounting of the component is necessary for replacement of the part, which is difficult to perform single-handedly, due to complicacy of the exhaust system construction. That is why installation of a new catalytic converter is performed only at a service station.
