How to Deal with Fogging on the Outside of the Car Windshield on Rainy Days?

There are several solutions to deal with fogging on the outside of the car windshield on rainy days, which are as follows: 1. First, adjust the air vents to the front windshield, turn on the air conditioning cooling function, and use the external circulation mode. With the maximum fan speed, it usually takes only about ten seconds to quickly "blow" away the fog on the glass. 2. Use the external circulation mode for defogging. However, this method is not as fast and may take some time. It is not suitable when the external environment is poor, such as when there is a lot of dust. For effective defogging with external circulation, the correct vent position should be set to blow both the front windshield and the footwell, or only the front windshield. Additional tips for driving on rainy days: 1. Turn on the windshield wipers when driving in the rain. Adjust the wiper speed according to the intensity of the rain. Some cars have an automatic adjustment feature. 2. If the weather is gloomy with thick clouds and poor visibility, turn on the driving lights. 3. Reduce speed when driving in the rain, as heavy rain can cause hydroplaning. Although this phenomenon is not common, it is important to be cautious, especially during heavy rainfall and when turning. Always slow down in advance and pay attention to deceleration.

What is the spark plug model for the New Alto?

The spark plug model for the New Alto is NGK platinum spark plugs. Under normal maintenance conditions, car spark plugs should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine, so it is recommended to follow the user manual. The following standards can be used as a reference 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. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, remove the high-voltage wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for external debris like leaves or dust and ensure they are cleaned thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the removed high-voltage wires according to the firing order and secure the cover.

What kind of road surface is indicated when the headlights change from far to near?

When driving, if the headlight illumination distance changes from far to near, it indicates that the vehicle is approaching an uphill slope, or is nearing the bottom of a downhill slope, or is approaching a curve. Additional information: 1. From near to far: When the headlight illumination distance changes from near to far, it indicates a sharp curve ahead, a large pothole, the vehicle reaching the top of a hill, or an upcoming steep downhill slope. 2. Moving from the center to the side of the road: When the headlights shift from the center to the side of the road, it indicates an upcoming curve in the opposite direction of the illuminated side. If the lights shift from one side of the road to the other, it means the vehicle is entering a series of curves. 3. Shadows appearing and disappearing: If shadows continuously appear on the road ahead and disappear as the vehicle approaches, it indicates shallow continuous depressions on the road. If the shadows do not disappear, there may be significant depressions or transverse ditches. 4. Dim light: If the headlights illuminate the road surface with dim light, it indicates an asphalt road. If the road appears bright and the light is clear, it indicates a gravel road.

Examination Process After One Year of Holding a B2 Driver's License?

B2 driver's license examination after the one-year probation period mainly tests knowledge of road traffic safety laws and regulations, safe and civilized driving, emergency handling, etc. After the exam, there is also a mandatory traffic accident case warning education session lasting no less than half an hour. Even with a perfect score, the exam is still required. Basic introduction to B2 driver's license: 1. Purpose of B2 driver's license: It allows driving heavy and medium-duty trucks or large, heavy, and medium-sized special-purpose vehicles. Heavy and medium-duty trucks are mostly trucks, such as the large dump trucks commonly seen on roads, which fall under the category of heavy-duty trucks. Large, heavy, and medium-sized special-purpose vehicles refer to vehicles equipped with special devices or equipment, such as sprinkler trucks, concrete mixer trucks, fire trucks, etc. 2. Other permitted vehicle types: Other vehicle types permitted under the B2 license include C1 (small cars), C2 (small automatic transmission cars), C3 (low-speed trucks), C4 (three-wheeled cars), and M (wheeled self-propelled machinery), which is the same as the B1 driver's license.

Why is the brake of Buick Excelle soft?

There are several reasons for the soft brake of Buick Excelle: 1. Air in the brake oil pipe: If air enters the oil pipe, the brake oil will appear insufficient in strength under high pressure. Although there is still braking force, the maximum braking force is significantly weakened. At this time, the air should be exhausted at the maintenance station in time; 2. Water in the brake: The brake system is actually composed of a set of hydraulic system. The brake caliper is braked by the hydraulic transmission of brake oil. When braking, the brake pads and brake discs generate heat through friction. These heat is transmitted to the brake oil through the brake cylinder, eventually leading to the increase of the temperature of the brake oil. When the brake oil is at high temperature, water will vaporize to form compressible gas. These gases are not fixed in position and quantity in the brake pipeline, resulting in soft brakes; 3. Oil leakage in the brake oil pipe: Oil leakage in the brake master cylinder or brake oil pipe cannot ensure sufficient oil pressure; 4. Replacement of oversized tires: Too large tires will lead to insufficient brake torque and weakened braking force; 5. The brake pads are too soft: The material of the brake pads is too soft and the high-temperature performance is poor. Brake pads that meet national standards should be replaced.

What are the models of oil nozzles?

The models of oil nozzles include M10*1, M8*1, and M6*1. More information about oil nozzles is as follows: 1. Low-pressure oil nozzle: Uses the power of combustion air to atomize fuel oil. Its advantages are lower power consumption for atomization and better atomization quality. The disadvantages are the complex structure of the nozzle itself, limited air preheating temperature, and smaller nozzle specifications. It is suitable for small heating furnaces without superheated steam. 2. High-pressure oil nozzle: Uses high-pressure superheated steam or compressed air for atomization, providing good and stable atomization quality. The combustion air does not directly contact the oil spray port, so air preheating is not limited, and the adjustment range is relatively large. It is easy to automate in centralized control and air-fuel ratio adjustment. The disadvantage is slightly higher energy consumption for atomization. This nozzle is suitable for large and medium-sized heating furnaces or general heating furnaces with superheated steam supply. 3. Mechanical atomization oil nozzle: A typical mechanical atomization oil nozzle is a high-speed rotating cup-shaped device. The oil forms a thin film adhering to the cup wall in the rotating cup and is atomized by centrifugal force at the cup mouth. Due to its rotating mechanism, this nozzle has a complex structure, and the atomization flame angle is too large, making it rarely used in heating furnaces.
