Brake system is a series of specialized devices that can forcibly reduce the driving speed of a vehicle. The brake system is mainly composed of four parts: energy supply device, control device, transmission device, and brake. The main functions of the brake system are to slow down or even stop a moving vehicle, maintain a stable speed for a vehicle going downhill, and keep a stationary vehicle from moving. Classification of brake systems: The brake system used to slow down or even stop a moving vehicle is called the service brake system; the brake system used to keep a stationary vehicle in place is called the parking brake system; the brake system that ensures the vehicle can still slow down or stop when the service brake system fails is called the emergency brake system; the brake system that assists the service brake system in reducing or maintaining speed during driving, but cannot stop the vehicle urgently, is called the auxiliary brake system. During driving, the service brake (foot brake) is generally used to facilitate slowing down and stopping while moving forward, not just to keep the vehicle stationary. The parking brake is only used when the service brake fails. After the vehicle comes to a complete stop, the parking brake (hand brake) should be used to prevent the vehicle from sliding forward or rolling backward.

Do spark plugs need to be replaced after driving 25,000 kilometers?

Generally, spark plugs do not necessarily need to be replaced after a car has driven 20,000 kilometers. Spark plug replacement cycle: Under normal maintenance conditions, spark plugs should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is recommended to follow the instructions in the user manual. You can refer to the following standards for maintenance and replacement: platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. How spark plugs work: Under high voltage, the air between the center electrode and the side electrode of the spark plug rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain level, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties and forming a discharge channel, resulting in a "breakdown" phenomenon. At this point, the gas forms a luminous body, known as a "spark." Along with the heat expansion, a "crackling" sound is also produced. The temperature of this electric spark can reach as high as 2,000-3,000°C, which is sufficient to ignite the air-fuel mixture in the combustion chamber of the cylinder.

How to Close the Hood of a Corolla?

The method to close the hood of a Corolla is to lower the hood support rod with one hand while holding the hood with the other hand, then slowly lower it. When the hood is about 30 centimeters from closing, release it to let it fall freely. A 'clunk' sound indicates successful closure. Below are additional details about closing the hood of a Corolla: 1. Precautions: Before closing the hood, always ensure the support rod is placed back into its clip. Closing the hood while the support rod is still extended may cause the hood to bend. Check and confirm that the hood is fully closed and locked. If the hood is not properly locked, it may open while driving, leading to serious accidents, injuries, or even fatalities. 2. Function: As the hood is a crucial part of the vehicle, any issues with it can affect normal car usage. Like other car components, the hood serves important functions. Learning the correct way to open and close the hood is essential. Regular maintenance of the hood can prolong its lifespan and prevent disruptions to normal vehicle use due to hood damage.

Can a BMW Key Still Work After Being Soaked in Water?

Key may not work after being soaked in water. If the soaking time is long and the key has short-circuited due to water ingress, it needs to be disassembled and dried to determine if it can still be used. Here is some additional information: 1. Wipe with tissue: If a car key gets wet, it's similar to a phone getting wet—do not press the buttons immediately, as this can cause water to seep into the inner layers faster. Use a dry cloth or tissue to wipe the surface clean, and use highly absorbent tissue to clean the inside. 2. Dry with cold air: Use a hairdryer on the cold setting to dry the key. Never use hot air, as the internal circuit board should not be exposed to high heat. Alternatively, you can place the key in a breathable bag and then into a dry rice container, as rice is highly absorbent and can draw out moisture. 3. Wipe with alcohol: Use a cotton swab dipped in high-concentration alcohol to gently clean the internal button contacts and other parts, as high-concentration alcohol has strong water-absorbing properties.

What to Do When the BMW Fuel Tank Cap Won't Open?

Methods to handle a stuck fuel tank cap: 1. If the fuel tank cap is stuck or rusty: Insert a small wooden piece into the gap of the fuel tank cap to pry it open, remembering to pull the fuel tank cap release switch. 2. If the fuel tank cap spring loses elasticity: You can install a small spring (not too soft or too long) on the protruding rubber pad of the fuel tank to increase the elasticity between the fuel tank cap and the locking mechanism. 3. If the fuel tank cap hinge or latch is worn out: Apply lubricating grease to the hinge and latch of the fuel tank cap. 4. If the fuel tank cap is misaligned: Some cars have thinner sheet metal, which may cause the fuel tank cap to misalign. In this case, visit a repair shop to realign it. 5. If there is a control circuit issue: For cars with remote-controlled fuel tank caps, besides the above issues, the small motor on the fuel tank cap might be burnt out, usually requiring motor replacement. 6. If the fuel tank cap is frozen or too dirty: If the fuel tank cap is stuck due to freezing weather or excessive dirt, clean or thaw it first instead of forcing it open to avoid secondary damage.

What Causes Weak Airflow from BMW X3's Air Conditioning?

Reasons for weak airflow from BMW X3's air conditioning: 1. Incorrect air direction: Check if the wrong air direction is selected. If the air is directed towards the windshield or side windows, it may feel like there's less airflow into the cabin. 2. Blower motor malfunction: A faulty blower motor can reduce airflow from the vents. Short circuits or decreased power in the blower motor will naturally result in weaker airflow. If the blower motor is the issue, it's recommended to have it inspected and repaired by a 4S shop or professional repair service, as this is not something owners can fix themselves. 3. Dirty air filter: A clogged air filter can obstruct airflow. The air filter is designed to remove impurities from the air entering the cabin. If too many impurities accumulate, airflow from the vents will be affected. Regularly clean the air filter using a vacuum cleaner to remove dust or an air compressor gun. If the filter is excessively dirty, replacing it is advisable. 4. Condenser blockage: A blocked air conditioning condenser can also lead to reduced airflow. Since the condenser is located at the front of the vehicle and is difficult to clean, it's best to leave this task to professionals to ensure thorough cleaning.

What to Do When the Car Fogs Up in Rainy Weather?

Here are the methods to deal with car window fogging in rainy weather: 1. Preventive measures such as applying anti-fog spray: Spray a small amount of anti-fog agent on the car windows (inner side) and wipe them clean to remove dirt and stains. While polishing the glass, a thin transparent protective film is formed on the surface, which effectively prevents the formation of fog caused by moisture condensation, especially suitable for cold winters. Alternatives to anti-fog spray include dishwashing liquid, soapy water, glycerin, alcohol, or salt water. After drying, wipe off excess residue with chamois or a soft dry cloth to ensure the car windows remain fog-free for several days. 2. Air conditioning cooling method: Use the air conditioning's cooling and dehumidifying function to reduce air humidity and eliminate fog. In summer, especially when multiple people enter the car, if the air conditioning is not turned on promptly, the high humidity from exhaled breath can quickly cause the windshield to fog up. At this point, turn on the air conditioning to blow cold air onto the windshield. Using the dehumidifying function, the fog on the windshield can be removed quickly. However, if the humidity is too high and the air conditioning is not effective enough, slightly open a window to rapidly reduce the humidity inside the cabin. Of course, combining both methods can yield faster results.
