Will traffic police check if changing from 16-inch to 18-inch wheels?

Changing from 16-inch to 18-inch wheels will be checked by traffic police. Here are the relevant details: Introduction: Illegal modification of motor vehicles will result in fines and an order to restore the original condition. If the structure, construction, or characteristics of a registered motor vehicle are altered, the owner must apply for a modification registration with the vehicle management office within ten days of the change; otherwise, they will be penalized according to the law. Notes: If owners wish to modify their wheels, they must not change the wheel size. Otherwise, the modification will not pass the annual inspection, and if discovered by traffic police, it will result in fines, making it not worth the effort. It is recommended that unless the wheels are damaged, owners should avoid unnecessary modifications.

Will sleeping in a car with windows closed cause suffocation?

No, but it is not recommended. Here are the specific details: Introduction: When the car is turned off and the engine is not running, sleeping inside will not cause suffocation. Even with the windows closed, the car body structure has some gaps, so the interior is not completely airtight. The oxygen concentration inside will not be too low to cause suffocation, though you may feel groggy upon waking up. Precautions: If the engine is left idling and you sleep in the car without opening the windows, this is inadvisable and poses a life-threatening risk. When the engine idles, incomplete fuel combustion produces carbon monoxide, which can accumulate inside the car. At certain concentrations, it can lead to poisoning. It is best to open the windows slightly to allow air circulation when sleeping in a car.

What do ex-factory price and transaction price mean?

In China, the so-called ex-factory price refers to the manufacturing price of the car itself, excluding insurance, purchase tax, license plate, etc. Below is specific information about it: Introduction: Transaction price = ex-factory price + various insurances + purchase tax + vehicle and vessel use tax + bridge toll (some places have this, some don't) + license plate fee. If it's a loan, there will also be service fees, interest, mortgage, and other such costs. Notes: In some places, there is another price called the all-inclusive price: generally, it refers to the price that includes getting the vehicle's license plate, allowing you to pick up the car and drive away directly. This price is similar in meaning to the on-the-road price, but it mainly emphasizes that it includes the cost of obtaining the license plate.

Several Reasons Why a Car's Air Conditioning Isn't Cooling?

Refrigerant being too much or too little, compressor damage or aging. Here are the detailed introductions of relevant information: Introduction: In the air conditioning system, the proportion of refrigerant has certain requirements, too much or too little will affect the cooling effect of the air conditioning. If the refrigerant is too little, the amount of refrigerant sprayed into the evaporator by the expansion valve will decrease, thus the cooling capacity of the refrigerant will also drop. Conversely, too much refrigerant will affect its heat dissipation, because more heat dissipation means greater cooling capacity. Compressor damage or aging: The air conditioning compressor is an important component to ensure the normal operation of the car's air conditioning. If the vehicle is relatively old and the air conditioning is not cooling, it is highly likely that the air conditioning compressor has problems such as looseness or aging, affecting the transmission efficiency, thus leading to unsatisfactory cooling effect. It is necessary to check whether the drive belt is broken, and then listen for any noise inside the compressor, these can all be used to judge.

Why does the fault code keep appearing after changing the engine oil?

If the fault code keeps appearing after changing the engine oil, it may be due to oil incompatibility. It is recommended to try a different engine oil. Here is some extended information about engine oil: Increased fuel consumption: When adding engine oil, the oil level should be between the upper and lower marks on the dipstick. If too much oil is added, the engine temperature will rise, causing the oil to expand in volume. This increases the pressure in the oil chamber and the running resistance, leading to reduced power and increased fuel consumption. Overfilling engine oil: If too much oil is added, the crankcase breather pipe may leak oil, and the increased pressure in the crankcase can cause the oil seal to loosen under the pressure, resulting in oil leakage.

Why does the car move forward instead of reversing on a steep slope?

R gear is the reverse gear. As long as the handbrake is not engaged or the brake pedal is not pressed, and the car is running, it will inevitably roll forward or backward according to the characteristics of physical inertia. Here are the relevant details: Introduction: For front-wheel steering vehicles, the driving trajectory is more sensitive to the steering wheel when reversing. Slightly turning the steering wheel too much will cause the front of the car to swing outward, and there is even a risk of overturning. There are often videos online of off-road vehicles losing control and overturning when reversing after failing to climb a slope, mainly due to excessive steering corrections at high speeds while moving backward. Precautions: If the speed is too high, the braking distance becomes longer, which is unsafe. Moreover, at high speeds, the ABS is more likely to activate when braking. On roads with insufficient traction, if the ABS is triggered, it can be quite terrifying, as the braking system may enter a deadlock state.
