Vehicles without a catalytic converter will be inspected on the road, and it is necessary to install one promptly. Below is detailed information about automotive catalytic converters: 1. Overview: The catalytic converter, installed in the vehicle's exhaust system, is the most crucial external purification device. It transforms harmful gases such as CO, HC, and NOx emitted from the vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. 2. Additional Information: When high-temperature vehicle exhaust passes through the purification device, the purifying agents in the catalytic converter enhance the activity of CO, HC, and NOx gases, promoting their oxidation-reduction chemical reactions. Because this converter can simultaneously convert the three main harmful substances in exhaust gases into harmless substances, it is called a three-way catalytic converter.

Should the RPM Be Raised to 2000 When Shifting from First to Second Gear?

When shifting from first to second gear, the RPM should be raised to 2000. The reasons for high RPM are: 1. Sudden increase in throttle opening; 2. Fuel injector leakage or blockage; 3. Slippage or damage to the air conditioning clutch; 4. Air intake system leakage; 5. Insufficient engine power output. Solutions for high RPM include: 1. Adjusting the throttle opening; 2. Replacing the fuel injector, air conditioning clutch, air intake system, or engine. The causes of unstable engine RPM are: 1. Oil residue or carbon buildup in the throttle; 2. Dirty intake tract; 3.
