2001 to 2003 Ford Ranger 3.0L & 4.0L V6 REAR Catalytic Converter

The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. It can convert harmful gases such as CO, HC and NOx emitted by the automobile exhaust into harmless carbon dioxide, water and NOx through oxidation and reduction. Nitrogen. When high-temperature automobile exhaust passes through the purification device, the purifier in the three-way catalytic converter will enhance the activity of the three gases CO, HC and NOx, prompting them to undergo a certain oxidation-reduction chemical reaction, in which CO is oxidized at high temperature into inert gas. Colorful, non-toxic carbon dioxide gas; HC compounds are oxidized to water (H20) and carbon dioxide at high temperatures; NOx is reduced to nitrogen and oxygen. Three harmful gases are turned into harmless gases, so that car exhaust can be purified.
