What to Do When Car Exhaust CO Levels Exceed Standards?

Solutions for excessive CO levels in car exhaust: 1. Clean the three-way catalytic converter: Use an IV drip method similar to human intravenous therapy to introduce cleaning solution into the vacuum tube of a running engine. The ingested solution burns away carbon deposits in the combustion chamber, enhancing engine power, then cleans the contaminated three-way catalytic converter in the exhaust pipe, restoring its original energy-saving and emission-reducing functions. 2. Repair aged or failed three-way catalytic converters: When the precious metals platinum, rhodium, and palladium inside have deteriorated and cleaning doesn't restore exhaust purification effectiveness, spray nano-precious metal (Pt-Rh-Pd) liquid into the removed converter. This achieves performance nearly equivalent to original equipment. 3. Install replacement catalytic material: Insert commercially available Fire Lotus three-way catalytic metal soft carriers into the exhaust pipe to serve as substitutes for the original converter's substrate, thereby improving exhaust purification.

Where is the horn located in the car?

The horn button is located in the center of the steering wheel, while the sound-producing horn is usually positioned inside the bumper near the front wheels. However, some vehicle models have their horns installed inside the grille. Therefore, to locate the horn, you need to first identify its approximate position. Here are some precautions regarding car horn usage: 1. Car horns are typically secured with clips and screws, and can usually be seen by opening the engine hood. It's important not to honk the horn indiscriminately while driving. Common honking patterns include one short beep or two short beeps. Avoid using the horn in areas with heavy pedestrian traffic. 2. Continuous horn usage should not exceed three times, and each honk should last no longer than three seconds. Prolonged honking can affect the driver's emotional state and easily lead to traffic accidents. 3. Never use the horn in school zones or no-honking areas, as doing so violates traffic laws and may result in penalties if caught by traffic police. During traffic congestion, exercise patience and wait.

Where is the ETC device number located?

The 6-digit ETC device number is also indicated on the installation form and can be seen on the front windshield. The purpose of the device number is to manage, maintain, pass through, troubleshoot, and deregister the ETC device. The highway operation system can query the operational status of the device through this code. ETC installation positions: For small vehicles such as cars and minivans, the ETC card and OBU device are installed in the upper middle part of the front windshield. For large vehicles like trucks and buses, the installation position is in the lower middle part. ETC installation position requirements: The height should be no less than 1.2 meters and no more than 2.5 meters; the installation angle N should be between 30º and 90º (the angle between the surface of the electronic tag and the horizontal plane). The installation process for the ETC device is as follows: Upon receiving the device, first check if the ETC card and electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU, and the red light will briefly turn on. The OLED screen will display "Tag Invalid" or "Please Insert Card," indicating the device is functioning normally. Clean the front windshield to ensure the surface is smooth, clean, and dry. Then peel off the adhesive backing film of the OBU and stick it to the installation position. Press firmly with your hand for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front facing the driver and the back facing the front windshield, ensuring the chip is inserted into the OBU device.
