Nissan X Trail catalytic converter scrap price

The catalytic converter of a car, which is usually called a catalyst, is an exhaust system unit that cleans exhaust gases from harmful substances. The effect is achieved through chemical oxidation and reduction reactions, as a result of which nitrogen oxides, volatile hydrocarbons and carbon monoxide are converted into water, nitrogen and carbon dioxide. The reactions take place with the participation of catalytic substances - platinum group metals, deposited on a ceramic (less often metal)honeycomb catalyst. There is a common misconception that removing the converter or honeycomb will increase the engine power. Let's figure out if this is so, what increase can be obtained and whether it is advisable to remove the catalyst to improve the performance of the engine.

The fine-pitch honeycomb significantly reduces the cross-section of the exhaust duct. To comply with the Euro-5 and Euro-6 environmental standards, a large active area is required, which prompts manufacturers of catalysts to reduce the diameter of the cells and use ceramics for their manufacture.

It is logical to assume that in a car without a catalyst, exhaust gases will leave the engine faster, the fuel mixture will become cleaner and its efficiency will increase. Measurements of power and fuel consumption at idle speed will help to check this assumption.

When assembling the exhaust system without a converter, the car needs to be flashed. With the removal of the catalyst , the indicators of the lambda probes change, which leads to the appearance of the Check Engine signal and a software decrease in the engine operating parameters. To get around this, modified firmware is used that disables one of the sensors and changes a number of other parameters of the chassis. The transformation of power indicators is influenced by both the physical absence of a catalyst and the transformations introduced by the firmware.

Measurements show the maximum power increase in the range of 3-4% when cutting out a normally operating catalyst. Fuel economy can be roughly the same. It is unlikely that this increase will turn out to be converted into some advantages when driving in a real city or on highways, and the minimum savings will not greatly replenish the budget. The harm to the environmental situation and the health of others from many cars without catalysts is enormous.

In a number of cases, growth is not observed at all, and there is even some retirement. Let's consider such a seemingly paradoxical effect on the example of KIA Rio. This car, like many other "Koreans' ', has a rather controversial technical point of view, the location of the catalyst. It is integrated into the short exhaust manifold at the junction of the pipes from the cylinders. This was done in order to achieve the required temperatures and increase the cross-section, saving on the manufacture of the catalyst, which requires a smaller active surface and the content of precious metals.
