Sealing oil serves to prevent the leakage of hydrogen generated by the combustion in automobile engines, while also purifying the oil. The following is an introduction to automotive sealing oil: 1. Sealing oil system: The function of the sealing oil system is to supply oil to the sealing bearing and simultaneously separate hydrogen, air, and moisture from the oil, thereby purifying it. 2. Principle of sealing oil: A continuous flow of oil is injected between the high-speed rotating rotor and the stationary sealing bearing to form an oil film that seals the gas, preventing the internal hydrogen from leaking and external air from entering. To maintain this continuous oil film, the oil pressure must be higher than the hydrogen pressure.

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.

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.

What are the symptoms of a faulty transfer case in a Mitsubishi Pajero?

The symptoms of a faulty transfer case in a Mitsubishi Pajero include the inability to switch to four-wheel drive mode or unusual noises while driving. Here is additional information: 1. Introduction to the transfer case: The transfer case is a device that distributes the engine's power, sending it to the rear axle or simultaneously to both the front and rear axles. The transfer case is essentially a component found in four-wheel-drive vehicles. As four-wheel-drive technology has advanced, transfer cases have also evolved, resulting in various distinct types. 2. Part-time four-wheel-drive transfer case: Part-time four-wheel-drive vehicles typically operate as two-wheel-drive vehicles but can switch to four-wheel-drive for off-road conditions. The part-time four-wheel-drive transfer case is a purely mechanical device. When engaged in four-wheel-drive mode, this type of transfer case creates a rigid connection between the front and rear axles, enabling a 50:50 power distribution between them, which significantly enhances the vehicle's off-road capability.
