What causes severe shaking when starting a cold BMW?

BMW experiences severe shaking when starting cold due to the following reasons: 1. Severe engine carbon buildup: When there is excessive carbon buildup inside the engine, the gasoline sprayed by the cold start injector is largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts, making it difficult to start and causing shaking. 2. Ignition system issues: Poor performance of the ignition system, such as spark plug misfiring, can lead to severe shaking when starting the car cold. 3. Unstable fuel pressure: Abnormal fuel pump supply pressure or incorrect readings and poor performance of the intake pressure sensor can cause body shaking. 4. Aging engine components: Worn-out components leading to engine mount issues can transmit vibrations to the steering wheel and cabin, causing shaking at idle.

What is the working principle of run-flat tires?

Run-flat tires work by utilizing sturdy sidewalls to provide support. Inside the tire, there is a device called a support ring, which can support the tire from the inside, preventing it from being crushed and also stopping the tire from detaching from the wheel rim. Run-flat tires are designed to continue functioning even after a puncture, and they are marked with the RSC (Run-Flat System Component) symbol on the sidewall. Structurally, run-flat tires are not significantly different from regular tires, except for the reinforced design on the sidewall. This reinforcement allows the tire to continue supporting the vehicle's weight and maintain driving even when it loses air pressure suddenly. The main difference between run-flat tires and traditional regular tires lies in the thicker and more robust tread design of run-flat tires, along with their stronger sidewalls that resist deformation. In the event of a puncture or sudden loss of pressure, the vehicle can still travel up to 250 kilometers at a speed of 80 kilometers per hour. The sturdy sidewalls ensure that the tire and wheel rim do not deform, keeping the vehicle's center of gravity stable and enhancing driving safety.

What Causes Small Bulges on the Side of Car Tires?

Here are the possible reasons for small bulges on the side of tires: 1. During tire usage, frequent friction with hard objects, prolonged overloading of the vehicle, or long-term use under non-standard tire pressure can all lead to bulging. 2. If bulges appear in multiple areas of the tire, it is largely due to quality issues. Defective products caused by manufacturing defects can also result in tire bulges. Problems in the raw materials or manufacturing process, including insufficient rubber composition, can lead to inadequate hardness and thickness of the tire sidewall, causing frequent bulging. 3. Impact on the tire, such as suddenly hitting a curb, quickly driving over a speed bump, or running over a large pothole, can cause severe compression. The internal air pressure increases, and the weak sidewall may bulge outward. 4. Poor road conditions, such as driving at high speed over rocky or rough roads, especially hard and uneven surfaces, or protruding manhole covers, can significantly impact the tire. Inconspicuous but highly damaging road irregularities can also be a major cause of bulges. 5. During vehicle use, avoid parking the car tilted against curbs to prevent sharp edges from puncturing or cutting the tire sidewall. When driving over speed bumps, slow down to minimize wear and thinning of the tire sidewall, which can lead to bulges. When purchasing or replacing tires, buy from authorized dealers to ensure quality reliability.

How to Stop the Wiper in the Middle?

1. First, power on the car: then activate the wiper function, setting the wiper to any gear. 2. Observe the wiper: when it reaches the appropriate position, turn the key to the OFF position. This will stop the wiper in the middle of the windshield. Wipers, also known as windshield wipers, are primarily used to remove raindrops and dust from the car's windshield, enhancing the driver's visibility and improving driving safety. Due to legal requirements, almost all vehicles are equipped with wipers. Rear windows of hatchbacks and SUVs also have wipers. Besides cars, other means of transportation like trains and trams are equipped with wipers. Even some engineering machinery, such as cranes, have wipers installed.

How to Remove the Cigarette Lighter After Pushing It In?

You can try to pull it out by hand, but avoid using excessive force. Gently twist and pull it vertically. If you notice the cigarette lighter glowing red and functioning normally, it indicates that the retaining spring in the socket is damaged. Replacement steps are as follows: 1. Locate the vehicle's fuse box for electrical components; it may be in the glove box or under the center console, depending on the model. 2. Open the fuse box cover and refer to the fuse location diagram attached to the inside of the cover to find the cigarette lighter fuse. 3. Use the provided fuse puller to remove the blown fuse and replace it with a new or spare cigarette lighter fuse.
