What are the inspection standards for car headlights?

Should the headlights be adjusted to 0 or 4?

Whether to adjust the car headlights to 0 or 4 depends on the driving conditions and the adjustment of the front headlight axis. If driving without heavy loads, luggage, or on flat roads, choose the normal position "0". If the number of passengers and the load or luggage in the car changes, the front headlight axis will be higher than the normal position. To adjust to the appropriate beam height, the higher the number marked on the corresponding switch, the lower the front headlight axis will be. Method for adjusting car headlights: Find a wall, ensure the ground is level, and park the car about 10 meters away from the wall. Measure the height from the ground to the center of the headlights and the distance between the two headlights. Place a horizontal masking tape on the wall 0.1 meters lower than the headlights, ensuring the tape is centered directly in front of the car. Turn on the headlights and adjust the vertical adjustment screw until the headlight beam is centered on the tape on the wall. Continue adjusting the vertical adjustment screw until the headlight beam is straight ahead. To ensure the adjustment is correct, measure the height of the beam on the wall and the height of the headlights to confirm they are equal. Precautions for using car lights: When a motor vehicle passes through an intersection controlled by traffic lights and turns left, the turn signal should be activated, and the low beam should be used at night. During periods when streetlights are on, or when driving in low visibility conditions such as fog, rain, snow, dust, or hail, the headlights, position lights, and rear lights should be turned on. When a following vehicle is driving close to the vehicle in front in the same direction, the high beam should not be used.

Is the 'Bang' Sound When Pulling the Handbrake a Sign of Breakage?

It is not broken. The sound occurs when the brake pads adhere to the brake discs. Lightly tapping the brakes a few times after starting the car will resolve the issue. Sometimes, this situation can also occur if the car is left unused after washing and driven the next day. Below are specific details about the handbrake: 1. Handbrake: The handbrake operates on the lever principle, using a steel cable to activate the rear wheel braking mechanism. The key components are the locking pawl and gear, which automatically engage together. 2. Pulling the Handbrake (Braking the Rear Wheels): When the handle is pulled, the pawl automatically springs up to catch the next gear tooth, while the connected steel cable gradually tightens, thereby applying the rear wheel brake pads. 3. Releasing the Handbrake (Releasing the Rear Wheels): When the handle button is pressed, the pawl and gear separate. Pressing down the handle then loosens the tightened steel cable, releasing the rear wheel brakes.

Where is the anti-theft control box located in the Buick Excelle?

Buick Excelle's anti-theft control box is located at the lower left corner of the steering wheel, and the key induction coil on the steering column is the anti-theft module. Purpose of installing the anti-theft device: The main purpose of installing the anti-theft central locking system is to control the vehicle's original central locking, achieving the goal of remote lock/unlock operation. Function of the anti-theft device: The vehicle anti-theft control system integrates the anti-theft device with power windows and central door lock control modules for centralized monitoring. When pressing the lock button on the remote control, the central door lock system engages. When the system enters alarm status, the door windows will automatically rise to prevent users from forgetting to close them, eliminating concerns about rain, wind, or theft, thus providing convenience for users.

Does a Small Gear Driving a Large Gear Speed Up or Slow Down?

A small gear driving a large gear results in a reduction in speed. When a small gear drives a large gear, the rotational speed decreases, which is based on the principle of gear ratio. When two gears of different diameters mesh and rotate together, the larger diameter gear naturally turns slower than the smaller one. The speed ratio is inversely proportional to the gear diameters. Below are the specific functions of gear engagement: 1. Changing speed or torque: There are many gears in the transmission and drivetrain. The gears in the transmission are used to change speed and torque, while the main reduction gear in the differential reduces speed and increases torque. 2. Power transmission: Gears serve a power transmission function. Many four-wheel-drive vehicles have numerous gears in the transfer case, which facilitate power transmission. The main reduction gear in the differential also aids in power transmission. Many gears transmit power by meshing with each other. Gears in the steering system also contribute to power transmission. 3. Achieving gear ratios: Different gear combinations in the transmission enable various gear ratios, allowing the vehicle to adapt to different driving conditions.

Is the EA211 spark plug not suitable for double platinum?

EA211 spark plugs cannot use double platinum. Spark plugs, commonly known as sparkers, function by discharging the pulsed high voltage electricity delivered by the high-tension leads, breaking down the air between the two electrodes of the spark plug to generate an electric spark, thereby igniting the air-fuel mixture in the cylinder. The following is an introduction to spark plugs: 1. Main types: The main types include standard spark plugs, projected insulator spark plugs, electrode-type spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs, among others. 2. Function: The purpose of a spark plug is to introduce tens of thousands of volts of high voltage into the combustion chamber and generate an electric spark to ignite the air-fuel mixture. Working in conjunction with the ignition system and fuel supply system, it enables the engine to perform work, collectively determining the engine's performance to a large extent. The electrodes of the spark plug repeatedly and continuously generate ignition sparks to ignite the air-fuel mixture in the cylinder. Meanwhile, other parts of the ignition system generate timed high-voltage pulses, forming sparks and creating explosions to provide the energy required for the engine's power output.

What is the tire pressure for a spare tire?

The air pressure of the spare tire should be between 2.3bar and 2.5bar. During driving, if the tire pressure is too high or too low, or if encountering sharp objects, the car tire may experience a blowout. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes the steering wheel to become heavy and prone to deviation, which are factors detrimental to driving safety; Increases the movement of various parts of the tire, causing abnormal heating due to excessive rolling; Reduces the functionality of the cord and rubber, leading to delamination or cord breakage, and excessive friction with the rim causing damage and abnormal wear at the bead area; Multiplies the friction between the tire and the ground, sharply raising the tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a blowout; Increases tire body deformation, making the tire side prone to cracks, while generating flexing motion, leading to excessive heat, accelerating rubber aging, cord fatigue, and breakage, and enlarging the tire's contact area with the ground, accelerating shoulder wear. Hazards of high tire pressure: Reduces the tire's friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern of the tire, shortening its lifespan; Increases vehicle body vibration, indirectly affecting the lifespan of other components; Overextends the tire cords, reducing the tire body's elasticity and increasing the load on the car during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks and blowouts due to impact.
