Here are methods to prevent poor visibility of car mirrors on rainy days: 1. Use cleaning products: Use soap, dishwashing liquid, or other cleaning products. Wet a clean cloth, apply soapy water or dishwashing liquid evenly on the mirror, and wipe it clean after drying. 2. Water repellent: There are many specialized water repellents for car mirrors available on the market. A simple spray forms a nano-functional film on the mirror surface, reducing the contact area between rainwater and the mirror. This prevents water from forming droplets and allows it to slide off quickly, achieving effective water repellency. 3. Install rain deflectors: Installing rain deflectors is a common method to prevent poor visibility of mirrors on rainy days. Rain deflectors effectively reduce the chance of rainwater falling on the mirrors, ensuring clear visibility.

Driving in the rain can be frustrating when the rearview mirror gets blurry. Here’s some practical advice from a 20-year veteran driver: Before setting off, clean the mirror with dish soap mixed with water—it leaves a water-repellent film when dry. While driving, remember to turn on the heated mirror function, which is now standard in most cars priced around 100,000 RMB. If your car lacks this feature, keep a microfiber cloth in the door pocket for quick wipes at red lights. Another great upgrade is installing wider rain deflectors—just 30 RMB on Taobao—which can block about 70% of rainwater. In heavy downpours, I adjust the AC vents toward the side windows to reduce fogging from temperature differences. Combine these tricks, and even the fiercest storm won’t faze you.

How to Repair a 12V Battery After It Runs Out of Power?

12V battery depletion can be repaired using the pulse repair method, which involves applying pulse voltage to the battery. This method can instantly achieve a pulse voltage between 60V and 300V, effectively repairing the depleted battery. It is a relatively safe method and poses no harm to the human body. The reasons for battery depletion include: 1. After the vehicle is stopped, the key is not removed or the vehicle is not completely turned off, leading to battery depletion; 2. Damage to the vehicle's generator, which prevents normal charging of the battery, resulting in depletion; 3. Short circuits in the vehicle's electrical system, causing battery depletion; 4. After the vehicle is parked, the headlights are not turned off, external dashcam power is not unplugged, or external seat heaters are not disconnected, which can also lead to battery depletion.

What are the symptoms of a broken car transmission?

The symptoms of a broken car transmission include noticeable clunking sounds, perceptible vibrations, and issues such as difficulty shifting gears, gear slippage, or a complete loss of gears. The transmission is a crucial component of a vehicle, responsible for altering the driving force and expanding the torque and speed of the driving wheels. The performance of the transmission is key to evaluating the power, fuel efficiency, and drivability of engineering machinery. Transmission systems mainly include: mechanical transmission, hydraulic transmission, and hydrostatic transmission. Transmissions can be manually shifted or power-shifted, with structures categorized as fixed-axis or planetary types. The torque and speed range of engines in engineering machinery is relatively small, making it insufficient to meet the requirements for traction and driving speed under various working conditions. Therefore, a transmission is employed to address these needs.

What Causes a Car Battery to Not Charge?

Generator belt aging, severe battery degradation, power cable detachment at the battery socket, or poor contact can cause a car battery to not charge. Generator belt aging: The engine directly drives the generator via the belt, and the generated electricity is then rectified and voltage-regulated before charging the car battery. Therefore, any abnormality in the belt will naturally prevent charging, necessitating timely replacement. Severe battery degradation: A car battery not charging is often due to deep discharge, meaning that when the vehicle is turned off, some onboard devices remain operational, continuously draining the battery. Over time, this will significantly accelerate battery degradation, leading to a situation where the battery no longer holds a charge. In such cases, replacing the battery is the only solution. Power cable detachment at the battery socket or poor contact: If the socket is detached, check for oxidation at the battery socket. If poor contact is the issue, simply reinserting the cable once may resolve it. Car battery charging precautions: Before charging, check the electrolyte level; do not charge if the electrolyte is insufficient. During charging, monitor the electrolyte density, voltage, and temperature. Ensure the charging area is well-ventilated and strictly no smoking or open flames. Never leave the battery unattended while charging.

What is the function of ABS in a car?

The function of ABS in a car is to prevent wheel lock-up during braking. Without ABS, emergency braking can cause the tires to lock up, resulting in longer braking distances and a tendency for the vehicle to skid or fishtail. ABS controls the locking of wheels by regulating the pressure of the brake fluid, keeping the wheels on the verge of locking while still rolling. The primary function of ABS is not to shorten the braking distance but to maintain the directional stability of the car during braking as much as possible. This system plays a significant role in driving safety, which is why ABS is now a mandatory feature in vehicles. The components of the ABS system include: the ABS module, ABS master cylinder, brake lines, and wheel speed sensors.
