The battery capacity of small cars ranges between 32ah and 80ah. Among them, the battery capacity of vans is 36ah, 40ah, 45ah, or 48ah, while that of sedans is 45ah, 54ah, or 60ah, and pickup trucks have battery capacities of 60ah or 80ah. Car batteries are divided into three types: conventional batteries, dry lead-acid batteries, and maintenance-free batteries. Conventional batteries: composed of lead and lead oxide; Dry lead-acid batteries: the negative plate has a higher storage capacity; Maintenance-free batteries: consume less electrolyte and do not require distilled water replenishment during their service life. Car battery maintenance methods: Regular inspection is necessary during use to keep the battery clean and dry, ensure the vent holes are unobstructed, and clean the exterior of the battery periodically; After the car is turned off, minimize the use of electrical appliances inside the vehicle; Car batteries have a limited lifespan, so they should be replaced regularly; If the vehicle is not used for an extended period, it should be started periodically.

Is Antifreeze Different for Diesel and Gasoline Vehicles?

Generally speaking, automotive antifreeze is not differentiated between gasoline and diesel vehicles. Below is relevant information about automotive antifreeze: 1. During cold winter parking, antifreeze prevents the coolant from freezing, which could otherwise crack the radiator and damage the engine cover or block. Antifreeze is not only for winter use; it should be used year-round. 2. The first function of antifreeze is corrosion prevention. Most parts of a car are made of metals like copper, iron, aluminum, and steel. Over time, these metals can corrode and rust when exposed to high temperatures and water. Antifreeze plays a significant role here by not only preventing corrosion in the engine's cooling system but also offering anti-corrosion and anti-rust properties. 3. The second benefit is its higher boiling point. Water boils at 100°C, whereas high-quality antifreeze typically has a boiling point above 110°C. Therefore, during summer use, it prevents the coolant from boiling over.

How many photos are taken for speeding?

At least three photos. Here is the relevant content introduction: 1. Two methods: one is to lay induction coils underground and install digital cameras on the crossbar to capture red-light running, and the other is to install cameras for real-time recording of speeding, red-light running, illegal parking, etc. 2. Three photos: Regardless of the method, at least three photos will be taken of the violating vehicle—one is an instant violation photo, one is a license plate recognition photo, and one is a panoramic photo. Regardless of the method, the cameras operate 24/7, and the photos are generally retained for one week. 3. Information comparison: After receiving the photos, the command center will compare the license plate information with the vehicle management office’s data to retrieve comprehensive vehicle information, such as the owner, model, color, etc. Then, the information processing staff will enter the data into the Beijing Public Security Traffic Management Bureau’s website so that the violating owner can check it.

What are the differences between platinum and iridium spark plugs?

Compared to platinum spark plugs, iridium spark plugs offer slightly better performance. Here are the specific differences between the two: 1. Performance differences: Iridium spark plugs have a higher melting point, allowing the electrodes to be made thinner and more focused. Compared to platinum spark plugs, iridium spark plugs perform slightly better. Platinum spark plugs have a melting point slightly lower than iridium and are priced at half the cost of iridium spark plugs, offering relatively better cost performance. 2. Stability differences: Under the same specifications, the performance of spark plugs only differs in electrode material. The main distinctions lie in lifespan and stability. In harsh environments, iridium spark plugs are more pressure-resistant and stable than platinum ones. However, iridium and platinum spark plugs from different brands and specifications cannot be directly compared. For example, platinum spark plugs installed in Mercedes-Benz vehicles will undoubtedly outperform mainstream iridium spark plugs in the market in terms of performance and stability.

What are the solutions for fogging on the outside of car windows?

Solutions for fogging on the outside of car windows include: 1. Car defogger: Evenly spray the car defogger on the inner surface of the car glass and wipe it clean; 2. Soap method: Slightly moisten the soap to make it softer, clean the glass, then evenly apply the soap over the entire glass surface, wait for the soap to dry on the glass, and remove the dried soap with a tissue or newspaper; 3. Use the car defogger button: On the car dashboard, you can see a 'front' button, which is the front window defogger, and a 'rear' button, which is the rear window defogger. Turn on the front and rear window defoggers. Initially, the fog on the glass may become heavier, but soon the fog will be dried by the warm air from the air conditioner, and the water vapor inside the car will disappear. The windows will remain fog-free for a long time, and the interior of the car will become warmer.
