Both high beams and low beams are used to illuminate the road ahead of the vehicle. The difference between high beams and low beams lies in the distance they illuminate—one shines closer, while the other shines farther. Typically, low beams have an illumination distance of about 30-40 meters and a coverage range of approximately 160 degrees. High beams, on the other hand, have more concentrated light with a brighter spot, allowing them to reach higher and farther distances. Below is relevant information: Switching between high and low beams: While driving, the driver should immediately switch from high beams to low beams under the following circumstances: 1) when an oncoming vehicle is approaching; 2) when the distance to the vehicle ahead in the same direction is relatively close; 3) when the road is already sufficiently illuminated; and 4) when entering a busy street. Additional information: The left symbol with a straight line represents the high beam indicator, while the right symbol with downward-slanting lines represents the low beam indicator. (Some car models may not display an indicator when low beams are activated.) The switch for toggling between high and low beams is usually located on the left side of the steering wheel. As shown in the illustration, when the switch is turned to the low beam position, pulling the lever inward will flash the high beams once, while pushing it outward will keep the high beams on continuously.

At what tread depth should tires be replaced?

Tires should be replaced when the tread depth is less than 2.5mm. A tread depth standard greater than 3.5mm is considered good condition, while between 2.5mm and 3.5mm is normal. When it reaches the minimum limit of 1.6mm, replacement is mandatory. Key considerations for tire replacement include: 1. Selecting tires of the same specification; 2. Replacing the valve stem simultaneously; 3. Paying attention to installation direction and inflation; 4. Checking tire pressure; 5. Performing a four-wheel alignment after replacement. The functions of tires are: 1. Transmitting driving force, braking force, and steering force to enable vehicle operation; 2. Supporting vehicle load; 3. Reducing and absorbing vibrations and impacts during driving to prevent severe vibrations from damaging automotive components.

Is a Lighter Prone to Explode in a Car?

Lighters are prone to explode in cars. The reason for this is: lighters contain pressurized gas. If placed on the dashboard or instrument panel where they are exposed to direct sunlight, the gas inside the lighter will continuously expand after prolonged exposure to heat. Upon reaching a critical point, an explosion can occur, which may cause severe damage to the vehicle. The main component of lighters is liquid butane, which is highly flammable and explosive. At normal room temperature of 20°C, it can explode. When a lighter is placed in an environment exceeding 55°C, its volume will expand. It is recommended that drivers who have the habit of smoking while driving should remember to take their lighters with them when exiting the vehicle to avoid potential hazards.

Can a car battery be charged directly in the vehicle when it's dead?

When a car battery is dead, it can be charged directly in the vehicle. During engine startup, the starter draws a significant current, which a regular charger cannot supply. If the battery is completely dead, the car won't start. However, if the engine can be started, the alternator will then charge the battery. The functions of a car battery include: 1. Providing power to the starting system, ignition system, and electronic fuel injection system during engine startup; 2. Supplying power to vehicle electrical equipment when the engine is off or idling at low speed; 3. Assisting in powering electrical devices when the alternator's output is insufficient; 4. Absorbing voltage spikes in the electrical system to protect electronic components; 5. Storing excess electricity generated by the alternator.

What are the two common cooling methods for engines?

Engines generally have two cooling methods: air cooling and water cooling. Air cooling involves numerous cooling fins on the engine block to increase the contact area with air; water cooling utilizes a cooling system where coolant continuously circulates within the engine to dissipate heat. The main components of an engine include: 1. Valve train; 2. Crankshaft connecting rod mechanism; 3. Ignition system; 4. Cooling system; 5. Lubrication system; 6. Starting system; 7. Fuel supply system. The function of an engine is to convert the thermal energy of gasoline or diesel into mechanical energy by burning the fuel in a sealed cylinder, causing gas expansion that drives the piston to perform work.

Can the original license plate be retained after a car transfer?

Whether the original license plate can be retained after a car transfer depends on different circumstances: 1. If both parties involved in the vehicle transfer are spouses, the original license plate can be retained; 2. If not, the license plate cannot be used on the original vehicle when the vehicle is sold and transferred normally. In this case, a new vehicle license plate must be selected during the transfer process. A vehicle license plate, also known as a car number plate and vehicle driving license, is a hard-coded plate with a unified format and style as stipulated by national vehicle management regulations. It is issued by the vehicle management authority after reviewing, inspecting, and registering the vehicle that has applied for the license plate, and it bears the registration code.
