What does PQ mean in vehicle safety inspection?

PQ in vehicle safety inspection means: 1. PQ is a term used in oil testing. 2. In oil testing, PQ refers to the amount of ferromagnetic particles in the oil, and the PQ value is also known as the mechanical wear index. Relevant information about vehicle safety inspection PQ is as follows: 1. The impact of PQ value on oil performance: If a large PQ value is detected during the inspection, it indicates that the oil contains a high amount of ferromagnetic particles, which further suggests that the mechanism may have severe local wear. 2. Working principle: The tested oil sample is slowly and steadily delivered by a double-tube infusion pump to the tray bracket above the magnet pole through the oil delivery tube. The ferromagnetic wear particles in the oil are adsorbed on the surface center of the tray bracket under the influence of a strong magnetic field. Meanwhile, the oil flowing through the strong magnetic field area is drawn back by the double-tube infusion pump through the return tube. Then, a cleaning solution with strong dissolving power and good volatility (such as tetrachloroethylene) is used to clean the inner wall of the oil delivery tube and the surface center of the tray bracket. After cleaning, the magnetic force acting on the ferromagnetic wear particles remaining on the surface center of the tray bracket is measured by the precision electronic balance through the tray, and the iron content reading (Fe value) of the oil is directly provided.

What is the traffic violation code 10390 and how is it penalized?

10390 refers to the traffic violation of motor vehicles violating parking regulations. It does not incur demerit points but carries a fine ranging from 20 to 200 yuan. Below is a detailed introduction to traffic violation codes: 1. Meaning of violation codes: Traffic violation codes are a set of encoding regulations established by the Ministry of Public Security for traffic violations committed by motor vehicles and pedestrians. 2. The first digit of the code: This is the behavior code, which includes numbers 1 to 5 and 7, 8. 1 indicates motor vehicle traffic, 2 indicates non-motor vehicle traffic, 3 indicates pedestrian or passenger traffic, 4 indicates highway traffic, 5 indicates other regulations, 7 indicates implementation rules of provinces, autonomous regions, or municipalities directly under the central government, and 8 indicates local regulations of cities (prefectures, autonomous prefectures, or leagues). 3. The second digit of the code: This is the demerit point classification code, which includes numbers 0, 1, 2, 3, 6, and 7. 0 indicates no demerit points, 1 indicates 1 demerit point, 2 indicates 2 demerit points, 3 indicates 3 demerit points, 6 indicates 6 demerit points, and 7 indicates 12 demerit points.

What are the symptoms of valves not closing tightly?

The symptoms of valves not closing tightly are as follows: 1. Difficulty in cold starting; 2. Unstable idle speed; 3. Body shaking and abnormal noises; 4. Weak acceleration; 5. Severe air leakage may cause the engine to fail to start. Additional information: 1. Whether the valves can close tightly directly affects the engine's starting performance and power output. During engine operation, the intake and exhaust valves are in a state of high temperature and high-speed movement. This rapid opening and closing cause the valves and valve seats to collide with each other, widening the contact surface and creating grooves. The high-temperature, high-pressure, and high-speed environment of the intake and exhaust valves makes the working surfaces prone to carbon deposits, burns, and pitting, leading to poor sealing between the valves and valve seats. 2. When the working surfaces of the valves and valve seats widen, the contact area increases. When the valves close, the unit area pressure on the valve seats decreases (the spring force of the valve springs remains unchanged), and this reduced unit area pressure also results in poor sealing between the valves and valve seats. Therefore, worn valves should be repaired or replaced promptly to avoid the aforementioned issues.

Is a tire pressure of 2.8 high in summer?

Summer tire pressure of 2.8 is very high. Generally, the lower limit of the standard tire pressure for car tires is sufficient. For example, the lower limit for standard tires is 2.4bar. If the car is often parked outdoors, the tire pressure can generally be about 0.1bar lower than the standard to avoid tire blowouts due to high temperatures. This is not normal. According to the provisions and requirements of the international GBT2978-2008 standard, the tire pressures for different tires are as follows: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; Maximum pressure: Should not exceed 3.5bar. Hazards of excessive tire pressure: The friction and adhesion of the tires will decrease, affecting braking performance; It can cause steering wheel vibration and deviation, reducing driving comfort; Accelerates localized wear of the tread pattern in the center of the tire, reducing tire lifespan; Increases body vibration, indirectly affecting the lifespan of other components; Causes excessive stretching and deformation of the tire cords, reducing the elasticity of the tire body and increasing the load on the car during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, and the impact can cause internal cracks and explosions, leading to tire blowouts.

Is a residence permit still required to obtain a driver's license in Foshan?

In Foshan, non-locals do not need to apply for a residence permit to obtain a driver's license. Currently, a residence permit is not required to take the driver's license test anywhere. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," there are two scenarios for taking the driver's license test in a different location: 1. Within the same province. Residents from different cities can apply directly with their ID cards and do not need to submit a residence permit or temporary residence registration certificate. 2. From another province. Residents working across provinces can apply for a small car driver's license anywhere in the province after obtaining a residence permit from any city within that province.

Is it necessary to install rain guards?

In general, it is not necessary to install rain guards. However, if the owner lives in a city with frequent rainy weather, installing rain guards can make driving more convenient. Rain guards are mainly installed on the left and right rearview mirrors and side windows of the car, serving functions such as maintaining clear rearview mirror visibility, shielding from rain, and blocking sunlight. Advantages of rain guards: 1. During rainy weather, when the window is slightly opened for ventilation, rain guards can prevent rainwater from entering the car interior; 2. To a certain extent, they can block direct sunlight from shining on the driver; 3. Installing rain guards on the left rearview mirror can prevent rainwater from blurring the mirror, allowing the driver to better judge the vehicles behind.
