07/30/25 3:47am
Car engine's normal idle speed ranges between 500 to 800 revolutions per minute. The maintenance methods for engines include: 1. Regularly changing engine oil and oil filters; 2. Maintaining good ventilation in the crankcase; 3. Periodically cleaning the fuel system; 4. Regularly cleaning the radiator; 5. Periodically cleaning the crankcase. An engine is a machine capable of converting other forms of energy into mechanical energy, suitable for power generation devices. Based on structural functions, engines are categorized into: 1. External combustion engines: Fuel burns outside the engine; 2. Internal combustion engines: Fuel burns inside the engine; 3. Gas turbines: Combustion produces high-pressure gas, which is used to rotate the turbine blades to output power.

What procedures are required for license plate transfer?

The procedures required for transferring a car license plate are as follows: 1. The required documents for license plate transfer include: the original ID card of the seller (copy required); the original ID card of the buyer (copy required); the original vehicle purchase invoice or the last transfer invoice (copy acceptable). 2. Other procedures and materials: the motor vehicle registration certificate of the vehicle to be transferred (copy required); the original vehicle license (copy required); the used vehicle sales contract and other materials. 3. License plate transfer between spouses is possible: Spouses can transfer license plates to each other. Taking Shenzhen as an example, according to Article 50 of the "Shenzhen Small Passenger Car Increment Regulation Management Implementation Rules," if one spouse transfers a locally registered vehicle under their name to the other spouse who has no car and no valid quota, the transfer can be directly processed with valid documents such as a marriage certificate, without the need to apply for a quota. This means that as long as the other party has no car and has not applied for a quota, the vehicle can be transferred to their name at any time.

Does installing tires backwards have any impact?

The impacts of installing tires backwards are as follows: Installing tires backwards can reduce the tire's grip, create uneven resistance on both sides, decrease the vehicle's braking effectiveness, make it prone to veering off course, cause unstable steering, and hinder water drainage during rainy weather, leading to potential safety hazards. Additionally, if tires are installed backwards, the vehicle's comfort will be affected, and tire wear will accelerate, causing the tires to wear out prematurely. Extension: 1. There are many methods to identify the correct side of a car tire, and the most direct way is to observe the English markings on the tire sidewall. The sidewall marked with "INSIDE" indicates the inner side (the side facing inward), while the sidewall marked with "OUTSIDE" indicates the outer side (the side facing outward). 2. Alternatively, you can identify the correct side by checking the manufacturing date on the tire sidewall. The manufacturing date on the tire sidewall is not displayed as XX year XX month XX day, but rather as a simple 4-digit number. For example, if you see the number 3513 on the tire sidewall, it means the tire was produced in the 35th week of 2013. The side with the production date is the outer side of the tire.

What is the purpose of a compressor?

Compressor is the power core of an air conditioning refrigeration system. It can compress the inhaled low-temperature, low-pressure refrigerant vapor to increase its temperature and pressure, making the refrigerant circulate inside, and achieving cooling effect through thermodynamic conversion. If we compare the refrigeration system to the human body system, the refrigeration compressor is one of the most important components in the refrigeration system, serving as the core and heart of vapor-compression refrigeration systems. Below is an introduction to compressors: 1. It extracts refrigerant vapor from the evaporator to maintain a certain evaporation pressure inside the evaporator; increases pressure by compressing low-pressure, low-temperature refrigerant vapor into high-pressure, high-temperature superheated vapor, creating conditions for condensation at higher temperatures; transports and propels the refrigerant to flow within the system, completing the refrigeration cycle. Thus, the process of raising refrigerant vapor from low pressure to high pressure and the continuous flow and transportation of gas are all accomplished through the operation of the refrigeration compressor. 2. Based on different principles of increasing gas pressure, refrigeration compressors are classified into positive displacement refrigeration compressors and dynamic refrigeration compressors. Positive displacement refrigeration compressors directly compress refrigerant vapor in a variable enclosed volume to reduce its volume and thereby increase pressure. Types of positive displacement refrigeration compressors mainly include reciprocating (also known as piston type), screw type, scroll type, rolling rotor type, vane type, and rotary vane type.

Can I still drive if my car has 12 points deducted?

The motor vehicle can still operate normally. The driving license has no points left to deduct. Traffic violation points are assigned to the driver rather than the vehicle. If a driver accumulates 12 points within a scoring cycle due to driving that vehicle, the traffic police department should confiscate their driver's license. During the period when the license is confiscated, the driver is not allowed to drive any motor vehicle. Below is extended information about driver's licenses: 1. Handling method: The driver must report to the traffic management department of the public security organ at the place where the motor vehicle driver's license was issued or where the violation occurred within fifteen days to participate in a seven-day study of road traffic safety laws, regulations, and related knowledge. After the motor vehicle driver completes the study, the vehicle management office should conduct an examination on road traffic safety laws, regulations, and related knowledge within twenty days. If the examination is passed, the points will be cleared, and the motor vehicle driver's license will be returned; if the examination is not passed, the driver must continue to study and take the exam. Drivers who refuse to participate in the study or take the exam will have their motor vehicle driver's license suspended by the traffic management department of the public security organ. 2. Motor vehicle handling method: The vehicle will not be prohibited from operating on the road just because its driver has accumulated 12 points. As long as there is a qualified driver, the motor vehicle can still be driven normally on the road.

What is the difference between car coating and crystal coating?

Car crystal coating and regular coating differ in brightness, working principles, and scratch resistance. The specific differences are as follows: Brightness difference: Crystal coating produces a diamond-like 3D iridescent effect, whereas regular coating only creates a crystal-clear mirror finish. Principle difference: Regular coating works by penetrating protective agents into the car paint to enhance its protection. Crystal coating, on the other hand, forms a protective layer of certain thickness on the paint surface, creating a solid shield. Scratch resistance difference: The thickness of the film layer formed by crystal coating is 2-3 times that of regular coating, resulting in significantly better scratch resistance.

Is It Normal for the Car Fan to Keep Running After the Engine Is Turned Off?

This is a normal phenomenon. If the engine coolant temperature at the moment of parking is higher than the acceptable soaking temperature for the engine, the vehicle's computer will automatically calculate the fan's operating speed and duration, thereby controlling the fan's operation automatically. The higher the engine temperature, the longer the fan will run after parking. When the engine coolant temperature drops below the soaking temperature, the fan will shut off to protect the engine and extend its service life. Below are common faults related to the car's cooling fan: 1. Whether the coolant temperature has reached the required level: Most car radiator fans operate based on electronic temperature control. Therefore, the fan will only start running normally when the coolant temperature inside the car reaches the required level. If the temperature is too low, the radiator fan will not operate. Thus, if your car's radiator fan fails to turn on, the first thing to check is whether the coolant temperature has met the requirement. 2. Relay malfunction: If the coolant temperature is appropriate but the car's radiator fan still does not work, the issue might lie with the fan's relay. A faulty relay can prevent the radiator fan from operating. 3. Issues with the temperature control switch: If neither of the above issues is present, then the temperature control switch should be inspected. Sometimes, faults in this component can also affect the operation of the car's radiator fan, so it is important to check this as well.
