What Are the Hazards of Engine Oil Leakage?

Engine oil leakage hazards are as follows: 1. The main hazard is the loss of engine oil, causing waste and environmental pollution. 2. Severe cases may lead to insufficient engine oil, resulting in engine damage, and even potential vehicle self-ignition. Common causes of engine oil leakage are as follows: 1. Damage to the front/rear crankshaft oil seal causing leakage. 2. Damage to the oil pan gasket or loose screws causing leakage. 3. Damage to the oil pump gasket or loose screws causing leakage. 4. Damage to the oil pan drain plug gasket, missing installation, or looseness causing leakage. 5. Improper assembly, damage, or loose screws of the timing gear cover gasket causing leakage. 6. Blockage of the rear crankshaft oil return thread by dirt causing leakage. Improper machining of the oil return thread or excessive coaxial deviation between the threaded journal and the oil seal seat hole causing leakage. 7. Poor sealing of the oil cooler/oil filter/valve cover gasket/distributor housing mounting hole causing leakage. 8. Deformation of the camshaft bearing rear cover/rocker arm cover or connecting rod cover/engine bracket plate, or poor gasket sealing causing leakage.

Do Rear Passengers Need to Wear Seat Belts?

Sitting in the rear seats of a car, passengers are required to wear seat belts. Article 51 of China's "Road Traffic Safety Law" stipulates that when a motor vehicle is in motion, the driver and passengers must use seat belts as required by regulations. During vehicle operation, if the driver or passengers fail to wear seat belts, it constitutes a violation of the law. Sitting in the rear seats without wearing a seat belt not only seriously endangers the safety of the front-seat occupants but also poses safety risks to oneself. The following are precautions for using seat belts: Regularly check the technical condition of the seat belt; if damaged, replace it immediately. The seat belt should be worn as much as possible across the hips and chest, forming a horizontally placed V-shape over the pelvis and rib cage. It should be used by one person only; sharing between two people is strictly prohibited, and the seat belt should not be twisted during use. When using the seat belt, avoid placing it over hard or fragile objects, such as mobile phones, glasses, or pens in pockets. When the seat is unoccupied, return the seat belt to the retractor and place the buckle in the storage position to prevent it from hitting other objects during emergency braking. Do not tilt the seat back too much, as this may affect the effectiveness of the seat belt. Ensure the buckle is securely fastened to prevent it from coming loose under external force and failing to provide protection.

Why Are Nails Always the Culprits of Flat Tires?

Rubber has a certain degree of tolerance. When the pointed tip of a nail comes into contact with a moving tire, the impact and load can cause the rubber to be instantly punctured. Many people don't pay attention to objects lying flat on the ground, and a small portion of them happen to have their sharp ends pointing upward. As soon as the wheel rolls over them, a puncture occurs. Some objects lie flat and aren't punctured by the front wheel, but due to the dynamic force of the vehicle's movement, they may flip to a sharp-up position just in time for the rear wheel to run over them. Below are relevant details: 1. Tire Material: The surface of a tire is made of rubber, which is not an absolutely rigid material. 2. Tire Load-Bearing: The weight of the vehicle and passengers is distributed across four tires, meaning each tire bears a significant load. Imagine a freely rolling tire passing over a nail with no load—it would be very difficult for the nail to puncture the tire. 3. Cause of Puncture: Rubber has a certain degree of tolerance. When the pointed tip of a nail comes into contact with a moving tire, the impact and load can cause the rubber to be instantly punctured.

Can the Shadow Leopard be equipped with a rear wing?

Shadow Leopard can be equipped with a rear wing. Advantages of installing a rear wing: It can improve driving stability. In addition to its aesthetic function, the main purpose of installing a rear wing is to provide necessary stability for the vehicle at high speeds. Especially for high-power vehicles, the rear wing can play a certain balancing role when cornering at high speeds or passing through complex road sections. Disadvantages of installing a rear wing: The fewer protrusions on the car's surface and the smoother the lines, the lower the wind resistance. The added rear wing will undoubtedly increase wind resistance. Since most sedans mainly drive on urban roads, the vehicle cannot reach the speed at which the rear wing can function effectively. The larger the wing, the greater the low-speed resistance, and the increase in the overall weight of the body will inevitably lead to higher fuel consumption. Precautions for installing a car rear wing: The height of the rear wing should be appropriate, and the size should be moderate. It should not extend beyond the trunk. Apart from poor appearance, it is also not allowed by road traffic safety laws. Of course, it should not be too small either, as a too-small wing can only serve as a decoration. Generally, the gap between the main wing and the body should be less than 2cm.

Does the car air conditioning system need cleaning?

Car air conditioning systems do require cleaning. More relevant information is as follows: 1. The function of a car air conditioning system is to provide a comfortable and healthy environment for passengers. During the operation of the air conditioning, the evaporator absorbs heat from the car to lower the temperature inside. Due to its low surface temperature, it remains in a damp state, which makes it prone to accumulating germs, dust, and other debris, especially in vehicles without an air filter. While driving, a large amount of dust and dirt can enter the air intake of the air conditioning system, accumulating in the air ducts and on the surface of the evaporator. On one hand, this can block the ventilation holes of the evaporator, reducing airflow; on the other hand, in a high-humidity, enclosed environment, it can breed a large number of harmful bacteria. These bacteria float in the air inside the car as it circulates, causing symptoms such as dizziness, fatigue, and nausea. Prolonged exposure can lead to respiratory diseases, posing health risks. 2. If not cleaned for a long time, when you turn on the air conditioning, you may notice musty, smoky, or foul odors, which are the root causes of health hazards. Therefore, regular cleaning is essential, especially before using the air conditioning in summer and the heater in winter. Generally, cleaning every 40,000 kilometers is recommended, including the evaporator and air ducts, followed by replacing the air filter.
