What is the headlight in Subject 3?

The headlight in Subject 3 refers to turning on the low beam to provide illumination for the driver. The headlight, also known as the front headlamp, is installed on both sides of the front of the car and is used for road illumination during nighttime driving. There are two types: two-lamp and four-lamp systems. The lighting effect of the headlights directly affects nighttime driving operations and traffic safety. Usage requirements: When using the car, it is necessary to have good illumination while avoiding dazzling oncoming drivers. When using the headlights, the following points should be noted: Keep the headlight lens clean, especially when driving in rain or snow, as dirt and dust can reduce the headlight's illumination performance by 50%. Some models are equipped with headlight wipers and washers. When two cars meet at night, both should switch from high beam to low beam when they are 150 meters apart to ensure driving safety. To maintain the performance of the headlights, after replacing them or every 10,000 km driven, the headlight beam should be checked and adjusted. Regularly inspect the bulbs, wiring sockets, and grounding for oxidation or looseness to ensure good contact performance and reliable grounding. If the connections are loose, turning on the headlights may cause current surges due to circuit interruptions, which can burn out the filaments. If the connections are oxidized, the bulb brightness may decrease due to increased voltage drop at the connections.

What are the advantages and disadvantages of air suspension?

Air suspension has the advantage of automatically adjusting the stiffness of the springs, but the disadvantage is that the purchase or optional cost is very high, and the maintenance cost is also particularly high. The function and working principle of air suspension are as follows: Function of air suspension: Air suspension systems are mostly used in off-road vehicles that frequently drive under harsh road conditions to ensure that the vehicle can smoothly pass through muddy, waterlogged, gravel, and other road surfaces. The most important point is that the elastic coefficient of the spring, or the stiffness of the spring, can be automatically adjusted as needed. Working principle of air suspension: Models equipped with air-adjustable suspension will have ground clearance sensors near the front and rear wheels. Based on the output signals from these sensors, the vehicle's computer will determine changes in the body height and then control the air compressor and exhaust valves to automatically compress or extend the springs, thereby reducing or increasing the chassis ground clearance to enhance high-speed body stability or off-road capability.

What to Do If You Forget to Get Your Car Inspected?

If the delay is within 1 year, there will be no fine. However, if the delay is between 1 to 3 years, a certain amount of late fees will be charged upon the next inspection. If the car has not been inspected for over 3 years—meaning it has missed three consecutive inspection cycles—the vehicle's registration will be canceled according to regulations. When to Perform Vehicle Inspection: For small and micro non-commercial passenger vehicles, new cars require inspection every two years within the first 6 years, and annually after 6 years. Medium-sized and larger vehicles require annual inspection. Vehicles can undergo inspection up to 3 months before the inspection deadline. Inspection Preparation: Ensure the vehicle's braking performance is good; handle any traffic violation records before the inspection; pay attention to the cleanliness of the chassis.

How Long Does It Take for a Car to Arrive at the 4S Store After Production?

It usually takes about 7 days to a month for a car to arrive at the 4S store after production, depending mainly on the transportation distance and the efficiency of the staff. Below is some relevant information: Concept: A 4S store, fully known as an Automobile Sales Service 4S Store, is a car sales enterprise that integrates four functions: vehicle sales (Sale), spare parts (Sparepart), after-sales service (Service), and information feedback (Survey). Business Scope: A 4S store is a car sales outlet that combines vehicle sales, maintenance, spare parts, and information services. Typically, a 4S store operates under a single brand in a region, with one or several dealerships distributed at relatively equal distances. These stores are built according to the manufacturer's unified design requirements for both interior and exterior, involving substantial investment and presenting a luxurious and impressive appearance.

What Causes the Boiling Water Sound When Starting the Engine?

Because the engine experiences a significant jolt at the moment of starting, impact sounds may occur in areas with excessively small gaps. Adjusting the deformed gaps can eliminate these abnormal noises. The boiling water sound from the engine is considered an abnormal noise and requires repair. Engine abnormal noises can generally be categorized into: Abnormal noises during cold starts, abnormal noises during rapid acceleration, and abnormal noises during idle. Abnormal noises caused by aging or loosening of the engine mounts. Engine mounts, also known as rubber mounts or engine brackets, are typically installed between the engine and the vehicle body, connecting the two and securing the engine in place. Their most important function is to provide cushioning and vibration damping. Once the engine mounts age or become loose, engine vibrations will intensify. During maintenance, the following aspects should be noted: If components such as the fuel filter, oil filter, air filter, hydraulic oil filter, and various filter screens become excessively dirty, the filtering efficiency will decrease, allowing more impurities to enter the oil passages and cylinders, accelerating wear on mechanical parts and increasing the likelihood of faults. Severe clogging can also prevent the vehicle from operating normally. Excessive piston temperatures in the engine can lead to overheating, melting, and cylinder seizure. Overheating of rubber seals, V-belts, tires, and other components can cause premature aging, reduced performance, and shortened lifespan. Overheating of coils in electrical equipment such as starters, generators, and regulators can easily lead to burnout and scrapping. Vehicle bearings should be kept at an appropriate temperature; overheating will cause the lubricant to deteriorate quickly, ultimately leading to bearing failure and vehicle damage.

Is it unnecessary to purchase auto damage insurance after several years?

Whether it is necessary to purchase auto damage insurance depends on the model of the vehicle and the financial situation of the owner. Below are the relevant details: Age limit: Private vehicles older than 8 years are generally not covered. Although it is possible to purchase auto damage insurance for vehicles over 10 years old, the coverage amount will be very low due to significant depreciation. Few insurance companies are willing to cover vehicles over 10 years old, and compensation is provided on a proportional basis. Definition of auto damage insurance: Auto damage insurance refers to the compensation provided by the insurance company within a reasonable range when the insured or an authorized driver causes damage to the insured vehicle during an accident. Coverage scope: This insurance does not cover theft, robbery, standalone glass breakage, standalone wheel damage, etc. Therefore, not all vehicle damages will be compensated by the insurance company after an accident.
