How To Clean Catalytic Converter Without Removing

A catalytic converter is a component that fits into the front part of the exhaust system of any vehicle to minimize the emission of gaseous pollutants such as VOCs, carbon monoxide, and nitrogen oxides. Cat converters are compact, durable, and reliable.

As you know, car engines either run on diesel or gasoline, both of which are made from petroleum. Even so, petroleum is comprised of hydrocarbons. Whenever hydrocarbon fuel is burned with oxygen from the air, it will release a great deal of energy. This happens because gasoline contains about 150 different chemicals, which together produce more than just power.

Remember that the pollution that’s been created by burning gasoline creates VOCs, carbon monoxide, and nitrogen oxides, which come together to form smog and haze. These things can harm the environment and reduce the quality of life for everyone in such areas. Related Post How to Unclog Catalytic Converter Hammer
