Here are the possible reasons for severe body vibration when accelerating: 1. Damaged spark plugs. 2. Worn spark plug electrode gap leading to insufficient spark. 3. Incomplete combustion of the air-fuel mixture causing vibration during acceleration. 4. Cracks in the ceramic part of the spark plug resulting in no spark, causing one cylinder to misfire which also leads to acceleration vibration. 5. Poor quality gasoline leading to inadequate fuel injector atomization, causing incomplete combustion in the cylinder and resulting in idle vibration. It is recommended to use higher octane gasoline after finishing the current tank and perform a fuel system cleaning.

What is the reason why the Benben M gear is normal but the D gear cannot shift up?

The reason why the Changan New Benben automatic transmission sometimes cannot engage is that the gear lock is locked or it is in P gear. Engaging P gear: When driving, shifting from P gear to other gears, Japanese cars generally require pressing the shift lock switch, while German cars generally require stepping on the brake. The P gear also has the function of a handbrake; it will not roll back on slopes below 15 degrees, but on steeper slopes, the handbrake must be applied. Checking the brake: You can try unlocking the gear lock with the key. If it still doesn’t work, then check whether the brake lights come on when you step on the brake. If the brake lights do not come on, the brake switch is damaged. The car computer cannot detect whether the brake is pressed, so the gear cannot be engaged. The brake switch is located below the brake pedal and can be replaced by yourself.

Will Water Enter the Fuel Tank When Refueling on Rainy Days?

No. Here are the specific details: Introduction: Because the engine's air intake goes through the air filter, which is located in the engine compartment and covered by the hood, water generally does not enter. Precautions for driving on rainy days are as follows: Maintain good visibility by promptly turning on the windshield wipers when driving in the rain, and also turn on the low beams and fog lights when the weather is dim. Prevent wheel skidding, as the car's braking performance deteriorates in the rain, making it prone to skidding. Important Notes: If encountering heavy rain, especially powerful thunderstorms that significantly reduce visibility, drivers should turn on all hazard lights and fog lights as a warning to prevent accidents caused by vehicles behind not seeing them. Additionally, the horn's sound has strong penetration in the air, traveling far and serving as an effective alert.

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.
