How to Deal with Excessive Car Exhaust Emissions?

Methods for handling excessive car exhaust emissions are as follows: Clean or Replace the Three-Way Catalytic Converter: The three-way catalytic converter is a major factor affecting excessive car exhaust emissions. In many cases, excessive emissions are caused by issues with the three-way catalytic converter. The function of the three-way catalytic converter is to oxidize CH and CO into carbon dioxide and H2O. If the three-way catalytic converter malfunctions, passing the exhaust emission test becomes difficult. Common issues with the catalytic converter include carbon buildup, clogging, poisoning, or failure. Cleaning the catalytic converter can resolve some problems, but if it is poisoned or damaged, timely replacement is necessary. Clean or Replace Spark Plugs: Faulty spark plugs can also lead to excessive exhaust emissions. The most common issue with spark plugs is carbon buildup, which can be cleaned using sandpaper or a cleaning agent. If the spark plugs fail due to erosion or reaching the end of their lifespan, they should be replaced immediately to avoid affecting normal vehicle operation. Check the Oxygen Sensor: When the car's oxygen sensor is clogged with carbon or malfunctions, it can affect the ECU's ability to properly regulate the air-fuel mixture and may also impact the performance of the three-way catalytic converter. It is recommended to clean the oxygen sensor and the catalytic converter simultaneously. Perform a Deep Engine Clean: After detecting excessive exhaust emissions, a thorough engine cleaning—including the throttle body, fuel system, intake manifold, and fuel injectors—can help restore the engine to normal operation. Methods for Detecting Excessive Car Exhaust Emissions: Radar Detection: Directly determines whether emissions exceed standards by analyzing the detection zone on the radar. Remote Sensing Detection: Uses remote sensing devices to measure emissions, with results displayed on the equipment screen. Electronic Capture: Utilizes traffic cameras to capture data. Manual Inspection: Conducted by traffic police during roadside checks, offering flexibility. Preventive Measures Against Excessive Emissions: Regularly maintain vehicle components, especially fuel injectors, oxygen sensors, and the three-way catalytic converter. Use high-quality fuel. Adhere to scheduled maintenance and maintain good driving habits during daily use.

Can the car door be opened when it is 50cm away from the wall?

Can the car door be opened when it is 50cm away from the wall? The answer is yes. A good car door will have at least two anti-collision beams inside, which are relatively heavy. This means that good car doors are indeed heavier. However, it doesn't mean that the heavier the door, the better. In modern cars, designers strive to reduce the weight of the vehicle, including the doors (using new materials), to minimize energy consumption, provided that safety performance and other factors are ensured. Here is an introduction to car doors: 1. Car door: A car door provides access for the driver and passengers and isolates external interference. It also helps mitigate side impacts to some extent, protecting the occupants. The aesthetics of the car are also related to the design of the doors. 2. Quality of car doors: The quality of car doors is mainly reflected in their anti-collision performance, sealing performance, ease of opening and closing, and other functional indicators. Anti-collision performance is particularly important because, during a side collision, the buffer distance is very short, making it easy for passengers inside to be injured. A good car door will have at least two anti-collision beams inside, which are relatively heavy. This means that good car doors are indeed heavier, but it doesn't mean that the heavier the door, the better.

What does highway ETC mean?

Highway ETC (Electronic Toll Collection) translates to electronic toll collection, which is a non-stop toll collection system. Highways are equipped with one or more ETC lanes. ETC charging method: Through dedicated short-range microwave communication between the onboard RFID tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, the system uses network technology to conduct background settlement processing with the bank. This achieves the purpose of vehicles passing through bridge toll stations without stopping to pay tolls. Banks install this type of ETC express card with a post-payment system. ETC application conditions are as follows: Provide the original and photocopy of the vehicle owner's valid ID and vehicle registration certificate. The photocopy of the driver's license must include the page with the most recent annual inspection stamp. Fill out a bank debit card application form, which will be used to bind the ETC card. After obtaining the card, you can go to a designated bank branch to receive and install the ETC onboard device for free, with no additional charges. Applicants must be between 18 and 60 years old and own a personal vehicle. Documents required for company vehicles: An introduction letter from the vehicle owner (with official seal); photocopy of the organization code certificate or business license (with official seal); original and photocopy of the agent's ID; original vehicle registration certificate; the vehicle that needs to apply for ETC. Precautions for installing ETC: Do not obstruct the view; it is best to install it behind the rearview mirror. Many car models have a large rearward angle of the windshield, which can reduce the driver's field of vision. If this is not considered during ETC installation, it may increase the driver's blind spots. Install it on the right side behind the rearview mirror to avoid obstructing the view. Do not affect charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement because it has a solar panel on the back that can charge itself. Therefore, during installation, avoid the black areas on the windshield and positions that may block the solar panel. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-removal lever connected to a switch. After the electronic tag is installed, the windshield will press the anti-removal lever in. If removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to go to an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device.
