Buick Enclave catalytic converter scrap price and the high price behind the catalysts

The production of catalysts is quite an expensive and complex process. The Buick Enclave catalyst is made from high-quality materials. In addition, expensive platinum is used as a chemical catalytic component that is able to withstand sulfur compounds.

Why a Buick Enclave catalyst is so expensive

In order to increase the efficiency of the catalyst, palladium and other rare earth elements are added to it. In order for the catalytic converter to serve for a long time, the following rules of operation should be observed:

• Refuel the car only with high-quality petrol;

• Do not be proud to start the engine, as unburned fuel is getting into the catalytic converter can lead to overheating and, consequently, to its failure;

• If the engine does not start after two or three attempts, it is necessary to stop so that the fuel accumulated on the surface has time to evaporate;

The likelihood of a catalyst failure is increased because of the release of some unburned fuel into the exhaust system during breaks. One of the spark plugs is faulty or the high voltage cable is damaged and the catalytic converter can be completely destroyed.

The catalytic converter of Buick Enclave and the function of lambda

For the Buick Enclave catalytic converter to work normally, it is necessary to ensure a constant optimal ratio of air and fuel in the working mixture entering the combustion chamber. Almost fifteen parts of air and one part of the fuel is a composition ensuring maximum combustion of the fuel-air mixture. The lambda probe was only designed to maintain this proportion. Depending on the oxygen content in the exhaust system, the sensor generates the appropriate voltage, and the control unit adjusts the mixture composition by changing the amount of fuel supplied to the cylinders. Typically, the sensor is located upstream of the catalyst and measures the oxygen content of the gases upstream of it. This means that the presence or absence of a catalyst does not affect the signals provided by the lambda probe. They are affected only by the amount of oxygen. Another thing is that there are two oxygen sensors, one in front and one behind the catalyst. Based on the signals from the second sensor, the mixture composition and oxygen content are further regulated after the gases have passed through the catalyst changes. Its absence may adversely affect the formation of a fuel-air mixture.

Buick Enclave catalytic converter scrap value

When the used Buick Enclave catalytic converter is sold, the replacement is surely needed.

When the catalytic converter is deleted, the control program changes and the lambda probe is simply removed. For some brands of cars, reprogramming is impossible, and if the failure of the sensor significantly affects the operation of the engine, there is no way out. Do not try to play around and trick the system, as it can cause some horrible outcomes. Contact the catalyst recycling companies or sell the used catalyst to the scrap yard.
