Focus on checking whether the three-way catalytic converter is clogged. Below is relevant information about the three-way catalytic converter: Working principle: When high-temperature vehicle exhaust passes through the purification device, the purifying agent in the three-way catalytic converter enhances the activity of CO, HC, and NOx gases, promoting certain oxidation-reduction chemical reactions. CO oxidizes into colorless, non-toxic carbon dioxide gas at high temperatures; HC compounds oxidize into water (H2O) and carbon dioxide; NOx is reduced into nitrogen and oxygen. These three harmful gases are transformed into harmless gases, thereby purifying the vehicle exhaust. Fuel injection system: The fuel injection system in a car engine generally consists of three major components: the fuel injection circuit, sensor group, and electronic control unit. If the injector is installed in the original carburetor position, meaning there is only one fuel injection point for the entire engine, this is single-point fuel injection. If injectors are installed on the intake pipe of each cylinder, meaning fuel is injected into the cylinders from multiple points (at least one injection point per cylinder), this is multi-point fuel injection.
