Is it acceptable not to display the 2020 inspection compliance sticker?

Currently, the annual inspection sticker must be displayed as there are no relevant policies indicating otherwise. Please note the following points: 1. Penalty for not displaying the sticker: According to Article 13 of the "Regulations for the Implementation of the Road Traffic Safety Law," the vehicle inspection compliance sticker and insurance sticker should be affixed to the upper right corner of the vehicle's front windshield. Failing to display these stickers as required is a violation of the law. If the annual inspection sticker is not displayed, the penalty is a 1-point deduction on the driver's license and a fine. 2. Digitalization of inspection stickers: In 2020, electronic inspection labels were widely promoted to replace the paper version of the annual inspection compliance sticker. Electronic inspection labels hold the same legal validity as the paper version. In provinces and cities where digital inspection stickers have been implemented, displaying the physical inspection compliance sticker is no longer mandatory.

How many kilometers can a car drive when the fuel tank warning light is on?

Generally, when the fuel tank warning light is on, there is approximately 10-12L of fuel remaining in the tank, allowing the car to drive for about 30-50 kilometers. Below are the impacts of low fuel levels: 1. Poor heat dissipation of the fuel pump: It is not recommended to continue driving when the fuel gauge shows empty, mainly to prevent poor heat dissipation of the fuel pump, which could lead to damage and avoid vehicle breakdown. You should refuel as soon as possible after the fuel warning light comes on. It is important to remind everyone to avoid filling the tank completely when refueling; instead, only fill it to 3/4 or 4/5 of the tank's capacity for optimal fuel levels. 2. Damage to the fuel pump: If driving on steep terrain with frequent uphill and downhill sections, fuel consumption will increase, which can also degrade the performance of the fuel pump. Insufficient fuel supply may cause the car to stall and become unable to continue driving, further severely damaging the fuel pump's performance.

How to Solve Abnormal Noise from Car Exhaust Pipe?

The causes and solutions for abnormal noise from car exhaust pipe are as follows: 1. Damaged exhaust pipe: The engine exhaust emits high-temperature and high-pressure waste gas, along with some backfire explosions. In this case, the exhaust pipe needs to be replaced immediately. 2. Engine misfire: The reason why car engines are not as loud as motorcycle engines is that the exhaust processes of each cylinder in a multi-cylinder engine (most car engines are four-cylinder) are interconnected. If one cylinder stops working, the exhaust sequence will be disrupted, causing abnormal noise from the exhaust pipe. In this case, only professional repair personnel can fix the issue.

What are the differences between the imported Kymco 400 and the domestic 400?

The differences between the imported Kymco 400 and the domestic 400 are as follows: 1. Transmission system differences: The transmission system of the imported Kymco 400 is significantly better than that of the domestic Xciting 400. The imported transmission system has less vibration, more linear acceleration, and much less noticeable low-speed vibration compared to the domestic version. Its vibration suppression is excellent, comparable to Japanese scooters. The domestic 400 vibrates particularly noticeably below 20-30 km/h and requires frequent cleaning of the transmission system; otherwise, the vibration becomes too pronounced. 2. Comfort differences: The imported Kymco 400 is better designed in terms of ergonomics, with superior materials, comfort, and handling compared to the domestic 400. The domestic 400 falls short in comfort when compared to the imported Kymco 400. 3. Price difference: The imported Kymco 400 is slightly more expensive.

What is the reason for the urea tank not making noise after parking?

When there is no noise after parking, it indicates a malfunction in the urea pump. The urea pump continues to operate after the engine is turned off to return the unused urea in the pipes back to the urea tank. Otherwise, the urea in the pipes may crystallize, affecting normal use during the next operation. Therefore, the urea pump continues to work for a while after the vehicle is turned off before stopping automatically. Below is an introduction to the urea pump: 1. Working principle and internal composition of the urea pump The urea pump is the core component of the SCR system, known as the "urea dosing pump." Its main function is to pump the urea solution from the urea tank and transport it to the nozzle through the delivery pipe. 2. Working principle of the urea pump The internal composition of the urea pump mainly consists of a diaphragm pump, electromagnetic reversing valve, pressure sensor, urea filter, electric heating system, lead frame, and other components. The exterior is composed of three urea solution pipelines: the spray pipe, return pipe, and inlet pipe. 3. Internal composition of the urea pump There are two types of urea pumps: one is the airless urea pump represented by Bosch, and the other is the air-assisted urea pump represented by Emitec and Cummins.

What is the appropriate wattage and lumens for LED car lights?

For car LED lights, a 35W model typically produces 3200 lumens, which is 91 lumens per watt. Generally, 80-100 lumens per watt is considered most suitable, but the specific choice should be based on the original vehicle's lighting power and individual brightness requirements. Theoretically, higher wattage in LED car lights means greater power and brighter illumination. However, in practice, higher wattage is not always better. Increased wattage leads to higher power consumption and operating temperatures, which demands more effective heat dissipation. Here are some key points about LED car lights: 1. The operating temperature of the LED chip must be kept below 85°C to ensure a lifespan of over 30,000 hours. If the LED wattage is too high, the increased power will raise the operating temperature. Exceeding 85°C will shorten the lifespan of the LED light as temperatures rise. 2. Since car electrical circuits have a rated power capacity, using LED lights with excessively high wattage that exceeds the circuit's load capacity can cause the wiring to overheat and potentially burn out. In terms of luminous efficiency, LED headlights of the same wattage are brighter than the original halogen bulbs.
