Is it recommended to replace the original car screen with an Android screen?

Nowadays, when purchasing a car, it generally comes with an original multimedia display screen. However, the navigation system on the original car screen is troublesome to update, and it usually only supports MP3 playback, while videos and other formats cannot be played. Under suitable conditions, it is recommended to replace it with an Android display screen for better functionality. Below is an introduction to the car central control system: 1. Central locking system: There are many types of central locks installed in cars, but their basic components mainly include door lock switches, door lock actuators, and door lock controllers. 2. Switches: Most central lock switches consist of a master switch and sub-switches. The master switch is installed on the driver's side door, allowing the driver to lock or unlock all doors in the car. Sub-switches are installed on other doors and can control a single door individually. 3. Actuators: The central lock actuator is used to execute the driver's commands to lock or unlock the doors. Door lock actuators come in three types: electromagnetic, DC motor, and permanent magnet motor. Their structures all work by changing polarity to reverse the direction of movement, thereby performing the locking or unlocking action.

What are the main contents of the secondary maintenance of a car?

The main contents of the secondary maintenance of a car are: 1. Replace the oil in the oil pan, and clean the oil pan, oil pump, and oil collector with kerosene; 2. Check and adjust the valve clearance; 3. Tighten the bolts of the cylinder head, intake and exhaust manifolds, and muffler, and check whether the gaskets of the above parts are intact; 4. Check the clutch and adjust the free travel of the clutch pedal as needed; 5. Check the fastening condition of each part of the transmission and gear shifting mechanism. The secondary maintenance of a car, in addition to the primary maintenance operations, mainly involves checking and adjusting safety parts that are prone to wear or deformation after a certain period of use, such as steering knuckles, steering rocker arms, brake shoes, suspension, etc., as well as disassembling and inspecting tires, performing tire rotation, checking and adjusting the working condition of the engine and exhaust pollution control devices, etc. These maintenance operations are performed by maintenance companies.

Where to Add Engine Oil to a Car?

Engine oil is added from the oil filler port on the left side of the engine. To perform operations such as changing the oil, simply unscrew the oil filler cap in the reverse direction. When reinstalling the oil filler cap, lubricate the cap opening with oil from the dipstick, then smoothly tighten it in the clockwise direction until it is securely in place. Basic steps for adding engine oil: 1. After the car is parked and the engine is turned off for about ten minutes, pull out the dipstick and wipe the oil traces clean with a cloth. 2. Reinsert the dipstick into the dipstick tube, then pull it out again to check the oil traces. Normally, the oil level should be between the upper and lower marks on the dipstick, slightly above the middle line. 3. If the oil level is below the lower mark, it indicates insufficient oil, and you should add oil immediately. While adding oil, continuously pull out the dipstick to monitor the oil level. 4. When topping up the oil, try to use the same type of oil as the one already in the engine to avoid mixing different brands or grades of oil.

What are the waterproof and breathable products for car headlights?

There are many waterproof and breathable products for car headlights. Currently, some of the better domestic brands include Dongguan PUWEI and Shanghai PUW. Advantages of waterproof and breathable products for car headlights: Automotive waterproof and breathable products can reduce condensation in headlights, block most contaminants, and maintain long-lasting brightness. Headlights are constantly exposed to various weather conditions, road conditions, and environments that may affect vehicle performance. Splashing water, humidity, automotive oil, road debris, and dust can all degrade headlight performance, affecting both appearance and safety. Rapid temperature drops can cause internal pressure to decrease, drawing in contaminants, increasing fogging, and potentially leading to headlight failure. Using PUW waterproof and breathable membranes for car headlights provides benefits such as preventing water fog, balancing pressure differences, preventing pressure buildup, dustproofing, and oil resistance. Extended industrial applications of car headlight waterproof and breathable products: These products can also be applied to car headlights, electric toothbrushes, electric hair clippers, electric shavers, mobile phones, car wiper motors, LED outdoor lighting, and more.

What is the definition of the 4 wires in a reverse camera?

DC power plug connects to the reverse light, generally only the red wire is connected, along with the red wire on the RCA plug, providing the signal for reverse video switching to the head unit. The RCA connector transmits the video signal from the camera to the head unit. Below are detailed introductions about reverse cameras: 1. Selection of reverse cameras: (1) For passenger cars, consider the camera model (optional waterproof and night vision features), screen size (3, 5, or 7 inches), and power supply voltage (12V). For large vehicles like trucks and buses, 24V is sufficient. (2) For large vehicles, selection should be more cautious. The operating conditions of large vehicles differ significantly from passenger cars. For example: harsh driving environments on construction sites, extreme temperatures, high frequency of reverse gear usage, and long working hours. Large vehicles typically use a 24V power supply, so reverse cameras designed for passenger cars cannot be used. Therefore, when selecting a product, ensure it is the right fit rather than being influenced by price or other factors. 2. Considerations: When choosing a reverse camera, ensure compatibility with your vehicle model by evaluating the camera model, power supply voltage, screen size, waterproofing, shock resistance, and anti-interference capabilities.

Is Yunliang Modification Legal?

Yunliang modification is legal. In 2016, Yunliang showcased four legally modified vehicles at a modification car exhibition, where the 'legalization' of automotive custom modifications became a hot topic. The four legally modified vehicles displayed by Yunliang at the exhibition—Justice, Tundra, Pickup Version Wrangler, and Savannah—attracted significant attention from attendees and became the highlight models of the event. Below is an introduction to car modifications: 1. Body Modification: This includes changing the car's color or adding decorative elements to the exterior or interior, enhancing the aesthetic appeal of the car's surface or interior. 2. Performance Modification: Performance modifications involve the car's braking system, suspension system, intake system, etc. Braking system modifications may include installing high-performance, high-temperature-resistant brake pads or larger brake discs. Suspension system modifications can involve replacing shock absorbers or reinforcing the suspension structure, with shock absorber replacement being the most popular choice among car owners. Additionally, modifying the car's air filter can improve the rate of air exchange.
