Where is the three-way catalytic converter installed in a car?
2 Answers
The three-way catalytic converter is installed in the automobile exhaust system and is the most important external purification device. The following is relevant information about the three-way catalytic converter: Introduction: The three-way catalytic converter, installed in the automobile exhaust system as the most crucial external purification device, transforms harmful gases such as CO (carbon monoxide), HC (hydrocarbons), and NOx (nitrogen oxides) emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction. Since this converter can simultaneously convert the three main harmful substances in exhaust gases into harmless substances, it is called a three-way catalytic converter. Precautions: Do not use leaded gasoline; avoid prolonged idling (open-loop control state); prevent sudden changes in engine speed; avoid excessively delayed ignition timing; when measuring cylinder pressure, disconnect the central control connector of the fuel pump to stop the injectors from spraying fuel into the cylinders.
The catalytic converter in my car is installed in the middle section of the exhaust pipe, specifically behind the engine exhaust manifold and before the muffler. You can see it most clearly by crouching under the chassis. This position is designed to utilize the residual heat from the engine, making the catalytic reaction more efficient, converting harmful gases like carbon monoxide and nitrogen oxides into harmless water and carbon dioxide. When I drove my old car, the catalytic converter got clogged, and the exhaust smelled strange. The mechanic suggested regular checks of this part to avoid impacts or dust buildup. If it malfunctions, not only will emissions exceed standards, but fuel consumption may also increase—best to check the chassis condition before long trips. Once you remember its location, you can quickly glance at it during car washes or maintenance to avoid major issues.
