Where is the location of the catalytic converter?

The catalytic converter is located in the vehicle's exhaust system. The working principle of the catalytic converter is: when high-temperature exhaust gases pass through the purification device, the purifying agents in the catalytic converter enhance the activity of CO, HC, and NOx gases, promoting certain oxidation-reduction chemical reactions. Among them, CO is oxidized at high temperatures into colorless, non-toxic carbon dioxide gas; HC compounds are oxidized into water (H2O) and carbon dioxide at high temperatures; NOx is reduced into nitrogen and oxygen. These three harmful gases are transformed into harmless gases, thereby purifying the vehicle's exhaust emissions.
I remember studying this a lot when I was into car modifications. The three-way catalytic converter is basically located in the exhaust system, specifically positioned between the exhaust manifold and the muffler, usually installed in the middle section underneath the vehicle chassis. When I inspect it myself, I always have to crawl under the car to check if it's tightly attached to the exhaust piping. The positioning is crucial because being close to the engine allows the catalyst to operate efficiently using the high temperatures. If it's misaligned or gets knocked out of position, the catalytic efficiency drops, potentially triggering the check engine light or causing excessive emissions. Don't forget about this component during routine maintenance - proper positioning helps reduce pollution. I also take photos with my phone to check for carbon buildup blockages; cleaning it improves exhaust flow. When properly positioned, the catalytic converter lasts longer and requires minimal maintenance time.
