What Causes Oil Leakage Under the Car After Parking?

Why Are Wheels Designed in a Circular Shape?

There are two main reasons why wheels are designed in a circular shape: efficiency and stability. The circular design of wheels helps reduce frictional resistance during movement. The axle, positioned at the center of the circle, rolls along the ground, ensuring smoother operation. By making wheels circular and placing the axle at their center, the distance between the axle and the ground remains constant, equal to the wheel's radius. This consistency enhances driving stability, as the vehicle's cabin is mounted on the axle and only moves smoothly when the wheels operate stably. Additionally, circular wheels minimize friction with the ground during travel, improving acceleration and overall vehicle efficiency.

What are the differences between Borui GE and Borui?

The difference between Borui GE and Borui lies in their powertrains: Borui GE is equipped with a 1.5-liter turbocharged engine and a 1.8-liter turbocharged engine; Borui is equipped with a 1.8-liter turbocharged engine and a 2.4-liter naturally aspirated engine. Both models share the same body dimensions, with a length, width, and height of 4956mm, 1861mm, and 1513mm respectively, and a wheelbase of 2850mm. In terms of exterior design, the Borui GE features flying-wing-style taillights composed of several flip light strips at the rear, which, like the headlights, use full LED light sources. The body sides and rear incorporate multiple chrome strips, along with trendy elements such as a wide horizontal rear end and dual exhaust pipes. The Borui's front grille adopts a square water ripple design with tension, and the lower grille has been updated from a ribbon-style to a blade-style, complemented by a horizontal chrome strip, giving the front face a more layered and three-dimensional appearance.

What is the appropriate normal kPa for wheel pressure?

Wheel pressure is normally appropriate at around 250 kPa. Tires are the only components of a car that come into contact with the ground, and they are crucial for the vehicle's driving stability and safety. Tires are very important for a car, and tire pressure is equally important for the tires. The tire pressure should neither be too high nor too low. If the pressure is too high, it will reduce the contact area between the tire and the ground, leading to decreased tire grip. If the pressure is too low, it can cause wave-like deformation of the tire during high-speed driving, which accelerates tire aging and increases the risk of a blowout. Tires are made of rubber, and rubber products will age over time with prolonged use, so tires need to be replaced regularly.

Why is there hot air when the car's air conditioning is off?

The reasons why there is hot air when the car's air conditioning is off are: 1. The internal circulation mode is not activated. When the air conditioning is turned off, the system automatically switches to external circulation mode to ensure air flow inside the car. The outside air passing through the engine compartment becomes heated; 2. The temperature control is not set to the coldest state, leaving the air mix damper open. This allows heat from the engine coolant to enter the car through the damper. External circulation: Uses a fan to draw outside air into the car. In congested urban areas, the car may fill with exhaust fumes. Internal circulation: Blocks outside air from entering the car, preventing harmful external gases and helping to maintain interior temperature.

Is it harmful to shift into P gear before the car comes to a complete stop?

Shifting into P gear before the car comes to a complete stop can cause significant damage to the vehicle's transmission system. If this practice is repeated over time, it can lead to severe wear and tear on the transmission, and in extreme cases, render the transmission unusable. When you shift into P gear while the car is still moving, it is equivalent to bringing the vehicle to an abrupt halt, forcibly locking the output shaft of the transmission. This can cause mechanical shock to both the parking brake and the locking mechanism of the transmission. The correct procedure for parking and shifting gears is as follows: Before coming to a stop, the car should first decelerate. Once the car is completely stationary, shift from D gear to N gear, engage the handbrake, release the foot brake, and then turn off the engine. After the engine is off, shift from N gear to P gear, and finally remove the key. It is important to note that for automatic transmission vehicles, the brake pedal must be pressed before parking; otherwise, shifting gears will not be possible.

Does a dented car door need to be replaced?

Whether a dented car door needs to be replaced depends on the severity of the dent. If the dent is minor, it can usually be repaired through metalworking techniques. However, if the dent is severe, replacing the door might be necessary. It's important to address a dented car door promptly to prevent rusting. Car doors provide access for drivers and passengers, isolate external disturbances, and to some extent, mitigate side impacts to protect occupants. The quality of a car door is primarily reflected in its crash performance, sealing performance, ease of opening and closing, and other functional indicators. Crash performance is particularly crucial because, during a side collision, the buffer distance is very short, making it easy for passengers inside the vehicle to be injured.
