Exhaust System auto parts: Pre-catalyst
Automotive catalytic converter serves to reduce the level of harmful substances in exhaust gases. Basically we are talking about carbon monoxide, hydrocarbons and nitrogen oxides, which in the course of the catalytic reaction are converted into harmless substances. In the vehicles with gasoline engines this work is done by a three-way catalyst that uses rhodium, platinum, and palladium as catalysts. The chemical reaction that takes place reduces harmful substances in exhaust gases. In the vehicles with diesel engines are used oxidation catalytic converters to transform hydrocarbons.
It is reasonable to install catalytic converters in older vehicles. Due to this it is possible to achieve higher environmental standards, which will provide significant tax benefits. A cheap alternative is a mini-catalyst. Functionality of the catalytic converter is determined by measuring the exhaust emissions. Rattling sounds also indicate a faulty catalytic converter. It is necessary to replace it. Faultiness must be repaired before passing the next test of the exhaust emissions level. For environmental reasons do not long delay the installation of a new catalyst.
In most vehicles the catalytic converter is installed between the oxygen sensor (lambda sensor) and the exhaust manifold. To replace the old catalyst it is necessary to disassemble the exhaust system. Usually this is done with the help of a diamond wheel. To install a new catalytic converter welding is required. In addition, the flange can be used. In our internet catalogue you will find many other spare parts, like fenders, brake shoes, cylinder locks, taillights. If you need a new oxygen sensor or any other car parts for exhaust system, you will find them here.
Signs of catalyst converter failure
Causes of Katalysator failure
Special equipment is required to diagnose faults of the Manifold catalyst. Therefore only qualified service station specialists can do this work. But there are external signs indicating existence of malfunctions. Noticeable damages which are found on external part of the catalyst are among them. It is necessary to replace the component in short terms in case you have noticed such defects.
Experts measure the productivity of a cell construction by the manometer attached to the place of the first oxygen sensor. Then the engine is accelerated to 3000 rpm. Readings of the system don't exceed value of 2,94 Pas or 0,3 kgf/cm2 at a safe pressure.
The standard term of operation of the catalyst converter is 100000 – 150000 operational kilometers. It is strongly recommended not to exceed this value and stop using a worn-out component. Reduction of cells capacity is dangerous for engine operation as it can fail because of pressure increase.
