What is the speed limit at urban traffic lights?

Traffic regulations do not specify a speed limit at traffic light intersections, but they do require drivers to slow down when passing through. The speed should not exceed the posted limit for that road; if the traffic light is at a crossroad or a turn, the speed should not exceed 30 km/h. Typically, the speed ranges between 30 and 60 km/h. Precautions when passing through traffic light intersections: Slow down in advance as you approach the intersection, then observe carefully and proceed at a relatively low speed to ensure safety. Driving at high speed through an intersection increases the risk of collisions with electric vehicles, pedestrians, or taxis. Rules for traffic lights at crossroads: When encountering a red light, vehicles (including bicycles, motorcycles, and electric vehicles) must not proceed straight or turn left but can turn right. When encountering a green light, vehicles can proceed straight or turn left or right (pay special attention to the directional arrows on the traffic light). When the directional light is green, vehicles can proceed in the direction indicated by the arrow on the traffic light. When the directional light is red, vehicles must not proceed in the direction indicated by the arrow. Traffic lights, also known as traffic signal lights, alternate light colors at specified intervals and are typically installed at intersections or other special locations to assign the right of way to drivers and pedestrians, regulating their movement and turns as part of traffic control facilities.

What Does Excessive Emissions Mean?

Introduction to the Causes of Excessive Vehicle Emissions: Vehicle Aging: If the vehicle's mileage has exceeded 450,000 kilometers or it has been in use for more than 15 years, various components of the car will show significant signs of aging, poor contact, poor sealing, and insufficient pressure. Failure of the Three-Way Catalytic Converter: The failure of the three-way catalytic converter is the primary cause of excessive vehicle emissions. The three-way catalytic converter, installed as the most important external purification device in the vehicle's exhaust system, converts harmful gases such as CO, HC, and NOx emitted from the vehicle's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. When high-temperature exhaust gases pass through the purification device, the catalyst in the three-way catalytic converter enhances the activity of CO, HC, and NOx, promoting specific oxidation-reduction chemical reactions. CO oxidizes at high temperatures into colorless, non-toxic CO2 gas; HC compounds oxidize into water (H2O) and CO2; and NOx reduces into nitrogen and oxygen. These three harmful gases are transformed into harmless gases, thereby purifying the vehicle's exhaust. Abnormal Engine Operation: The engine may experience issues such as misfiring, spark plug oil leakage, or oil blow-by. When the throttle is increased, the engine does not run smoothly and powerfully.

Is there a fee for vehicle inspection re-examination?

There is a fee for vehicle inspection re-examination. The annual vehicle inspection includes several testing items. If any item fails, the corresponding item will require a certain debugging fee and re-inspection fee before it can be tested again. However, failed items generally get one re-examination opportunity. If they still fail, the vehicle owner must take the car to a repair shop for maintenance and then pay again for re-inspection. Emission Test: The emission test is the first item in the annual inspection, mainly checking whether the vehicle's exhaust emissions of harmful gases and substances such as hydrocarbons and PM particles meet the standards. Violation Check: This primarily verifies whether the vehicle owner has any unresolved traffic violations. If there are no violations, the staff will stamp the documents, and the inspection can proceed. Otherwise, the owner must resolve the violations before returning for the annual inspection. Exterior Inspection: This mainly checks for damage to lights and glass, changes to the suspension, and the condition of the sunroof, body, tires, and other exterior parts. On-Road Test: The on-road test is essentially the final inspection item, primarily assessing the vehicle's braking performance, lighting system, horn, chassis, and other components.

What Causes the Noise After Replacing the Three-Way Catalytic Converter?

After replacing the three-way catalytic converter, the noise in the car may be caused by a cracked shell or a damaged filter. Cracked Shell: Visit a repair shop to have a technician perform welding. It is not recommended for car owners to remove the three-way catalytic converter themselves, as this involves disassembling the oxygen sensor, which requires certain technical skills. Damaged Filter: Replace it again. Lifespan of the Three-Way Catalytic Converter: The service life of a three-way catalytic converter ranges between 80,000 to 100,000 kilometers. The specific lifespan depends on the vehicle's usage conditions, as well as the quality of the fuel used and the driving environment. Composition of the Three-Way Catalytic Converter: The three-way catalytic converter generally consists of four parts: the shell, damping layer, substrate, and catalyst coating. The shell is made of stainless steel to prevent oxide scale from falling off, which could clog the substrate. The damping layer is composed of gaskets or wire mesh pads, serving to seal, insulate, and secure the substrate. To protect the substrate from damage caused by vibration, thermal deformation, and other factors, the gasket is made of expanded mica and aluminum silicate fibers, bonded with adhesive. The substrate is made of honeycomb-shaped ceramic materials, though many also use metal (including stainless steel) materials. The catalyst consists of precious metals such as platinum, rhodium, and palladium, sprayed onto the substrate to form the purifying agent.
