Why Catalyst is So Important

It’s no accident that a catalyst is quite an expensive vehicle element. Did you know that the price of a cat may reach 13% of the total car cost? It was designed to oxidize harmful compounds of exhaust gases and almost eliminate their toxicity due to catalytic chemical processes.

How Does It Work?

A cat consists of a steel body, ceramic cylinder with many holes reminiscent of a honeycomb covered with a thin layer of an alloy oxidizing exhaust gases. The bigger the contact area is the better, that’s why the internal element is made in the form of a honeycomb. Heat is released by the oxidation process and makes it more effective.

A car cat is an essential part of the entire exhaust system. The mandatory use of this device is regulated by most countries of the world since environmental issues are common for everyone.

The catalytic layer contains many precious metals, such as platinum, rhodium, and palladium. Their high cost defines the cost of the converter. By the way, you may earn some money for an old, clogged, or damaged device for a new one.

Catalyst plays its role in the process of fuel distribution. A modern vehicle simply won’t go as it should without a missing part of the exhaust system due to the wrong fuel supply parameters.

That is why the replacement of an old catalyst is needed.

If you decide to remove it, you have to be ready to permanently distracting the Check Engine light meaning that you may fail to identify a true motor trouble at the proper time. Besides, let’s remember about the fine for using a vehicle without a cat. Is removing worth it? Engine power loss due to a cat is a popular myth. All you need it to fill your vehicle with unleaded fuel to keep the device in good operating condition.
