Start-stop batteries have specific markings on their exterior, including: st, q85, n55, efb, iss, agm, etc. Start-stop batteries allow the car to automatically shut off when temporarily stopped and restart the engine when the car moves forward, thereby achieving energy savings and emission reduction, lowering tailpipe emissions. The function of the battery is to store electrical energy, supplying power for car starting, ignition, lighting, signals, and audio-visual equipment. Its working principle is: car batteries use lead-acid batteries based on the primary cell principle. When the load is connected, the lead on the negative plate reacts with sulfuric acid to form lead sulfate and lose electrons, while the lead oxide on the positive plate reacts with sulfuric acid to form lead and water, gaining electrons, thus generating an electric current.

Is the Audi Q5 body made of aluminum alloy or iron?

Audi Q5 body uses high-cost imported aluminum in multiple areas. The materials used in the body and maintenance methods are as follows: Materials used in the Audi Q5 body: The Audi Q5 does not use aluminum material for the entire body, but high-cost imported aluminum is used in multiple areas. The Q5 features aluminum front and rear five-link suspension materials, which are five times lighter than iron suspensions, resulting in reduced unsprung mass. Additionally, it has aluminum engine hoods and tailgates, and even the brake pedal linkage is made of aluminum alloy. Maintenance of the Audi Q5 body: Do not park the car under direct sunlight for extended periods. Also, regularly clean dust from the door seals to prevent accelerated aging. If the car is left in the sun for too long, it can cause the door seals to age faster, leading to wind noise and impact sounds between the door and door frame.

What are the consequences of not scrapping a motorcycle that has reached its end-of-life period?

Motorcycles that have reached their end-of-life period but have not been scrapped will face the following consequences: 1. If the motorcycle owner fails to legally complete the deregistration process, the vehicle management department will not process any new vehicle registration or transfer procedures for them; 2. The vehicle management department will also revoke the registration certificate, license plate, and driving license for those who fail to obtain the inspection qualification mark within the specified period; 3. For those who fail to complete the deregistration procedures within the deadline, a mandatory deregistration notice will be issued. A motorcycle is a flexible and fast means of transportation, powered by a gasoline engine and steered by handlebars to control the front wheel. It can be a two-wheeler or three-wheeler, known for its light weight, agility, and speed, widely used for patrol, passenger and cargo transportation, and as sports equipment.

What is the capacity of car windshield washer fluid?

Car windshield washer fluid capacity is approximately 1.5 liters. Windshield washer fluids are categorized into summer-use 0°C fluid and winter-use -20°C or -35°C fluid. The functions of windshield washer fluid are: 1. Maintaining clear visibility through the windshield while driving; 2. Extending the lifespan of both the windshield and wiper blades; 3. Preventing window icing in winter; 4. Eliminating static electricity on windows. The method for adding windshield washer fluid is: 1. Activate the wiper switch, causing the fluid to spray from nozzles below the windshield; 2. Continue until nozzles stop spraying, then open the washer fluid reservoir cap to add fluid; 3. Reactivate the wiper switch to clear remaining fluid; 4. When no more fluid sprays out, refill the reservoir and securely close the cap.

What Causes the Noise When Braking in Reverse?

Reasons for noise when braking in reverse: When braking in reverse, which is opposite to the vehicle's forward direction, there is a certain amount of clearance between the brake pads and the rear end of the bracket. Therefore, during braking, the brake pads impact the rear surface of the bracket, resulting in abnormal noise. The working principle of braking mainly relies on friction. By utilizing the friction between the brake pads and the brake discs, as well as between the tires and the ground, the kinetic energy of the moving vehicle is converted into heat energy through friction, bringing the car to a stop. To mitigate the noise when braking in reverse, a thin layer of lubricating grease can be applied to the parts where the brake pads connect with the brake caliper bracket. This can help improve the phenomenon to some extent.

Why does the engine light sometimes turn on and sometimes off?

The engine warning light sometimes turning on and sometimes off indicates there is an issue with the engine. The intermittent nature of the light suggests the problem is not yet severe. When the issue does not affect normal driving, the engine warning light will turn off, but it will illuminate when a fault is detected. Common causes include: 1. Excessive carbon buildup in the throttle body or engine internals. 2. A faulty oxygen sensor leading to an imbalance in the air-fuel mixture. This often occurs with prolonged low-speed city driving. 3. Fuel injector leakage causing continued fuel supply after throttle release, resulting in an overly rich mixture at low speeds and unstable idle. In severe cases, this may cause the engine to stall. 4. Use of substandard gasoline with excessive metal content, poisoning the oxygen sensor. The solution is to switch to a different gas station.
