Advice 1: How to clean the catalyst

The catalytic Converter is a device that converts automotive exhaust gases to less environmentally harmful compounds. Breakage of the catalyst leads to a decrease in speed and an increase in heating of the motor. Is it possible just to clean the catalyst without removing it?
How to clean the catalyst
Instruction
1
To determine the poor condition of the catalyst in your car is possible on the following grounds: increase in consumption of gasoline deterioration of traction, the car starts from cold start. In more advanced cases, the engine continually stalls, and the exhaust gases from the pipe do not go or pass with difficulty. If you see something like that, it is time to clean or change the catalyst.
2
The most effective way to eliminate problems with catalyst replacement. Many drivers just remove the damaged part, and go, poisoning the environment with harmful emissions. Besides, riding without a catalyst becomes less convenient – the engine noise so that in the car there is a significant vibration, and the car at the start too abruptly takes off. If you care about the air in his hometown and you prefer a comfortable ride, it is better not to regret money and to buy a new catalyst. You can also try to clean your hands.
3
Remove the catalytic Converter and inspect it. Often it happens that the nuts are tightly stuck, and remove them can be difficult. View "cell" transmission. If no mechanical damage (burnout, subsidence and other), you can try to wash out the detail. If there is a visible destruction of the honeycomb, the catalyst is better to just throw it away and put a new one.
4
Blow out the honeycomb karlspreis. If hard deposits too much at night, leave the catalyst in any capacity with diesel fuel, kerosene or other similar liquid. Then repeat the procedure purge karlspreis. Most often this procedure helps to restore the catalyst to life and prolong the period of its operation.
5
In some cases, to facilitate the work of the motor, motorists prefer to drill in the catalyst openings using pobeditovye drill or, much less accurately, just punch a hole with a crowbar. After this procedure the machine will work better, but the harm to the environment will increase.

Advice 2 : How to remove catalyst from the WHA

The catalytic Converter effectively purifies automobile exhaust gases. Harmful hydrocarbons, carbon monoxide and nitrogen are transformed into non-toxic compounds – water vapour, carbon dioxide and nitrogen. Sometimes catalysts are deteriorating and require replacement or removal. It's easy to do.
How to remove catalyst from the WHA
You will need
  • Wrenches, pliers, lift or pit, new catalytic Converter, electronic emulator of a catalyst, a heat-resistant tube.
Instruction
1
Determine that the catalyst has deteriorated. It is possible to hear, to smell, to see. Broken ceramic rattles in a metal enclosure like a rattle when the car goes over a rough road. Faulty exhaust gases in the catalyst become hydrogen sulfide smell. Their color also varies from almost transparent to black or grey. When driving the engine is warmed up with labour gaining more than 3 thousand revolutions.
2
Raise the car VAZ on the lift or drive it on the overpass. Or remove the catalytic Converter over a garage pit.
3
The stainless steel inside which is placed the catalyst built into the system just behind the exhaust manifold of the engine. Unscrew two nuts of fastening of a pipe of the resonator to the catalytic Converter. Remove the spring washer. Remove the bolts.
4
Unscrew the two bolts securing the catalytic Converter to exhaust front pipe. Remove the bolts together with the springs, be sure to hold the catalyst with your hand so that it does not fall. Ceramic catalyst fragile and collapses from shock, ingress of water on a heated body, due to poor quality fuel problems with my engine, and much more. For example, riding around town with short runs and frequent starts of the engine it clogs up the honeycomb fuel and soot. And on high-speed motorways catalytic Converter is overheating.
5
Remove the catalyst from under the car. Purchase a new catalytic Converter and install it in place of the exhaust in the reverse order of removal. Often the high cost of the catalyst becomes an obstacle for his replacement.
6
The old catalyst will split, shake the filling to the tank became empty, weld metal and install back. Or is Converter will Waite a piece of heat resistant pipe of suitable size. And for the correct operation of the lambda probe (oxygen sensor) install the electronic emulator of the catalyst (hornblende), which will simulate the presence of intact devices.
Note
The content of harmful substances at the exit of your vehicle will increase dramatically. Three-way catalytic Converter is made of special ceramic or metal monolith with a large number of cells, resembling a honeycomb. A rough surface increases the contact SOT deposited on the entire surface equal to the size of a football field, a thin catalytic layer of platinum, palladium and rhodium, which weigh only 2-3 g.
Without this protection, the car is much less environmentally friendly. This fact may affect receiving pass technical inspection of the vehicle.
