What are the symptoms of a faulty fuel pump in a car?

When a car's fuel pump is damaged, the engine typically exhibits symptoms such as sluggish acceleration and abnormal noises. Below are detailed descriptions of the car's condition when the fuel pump is faulty: Sluggish Acceleration: There is a jerking sensation during sudden acceleration; the car is difficult to start and requires prolonged turning of the key. Abnormal Engine Noises: Unusual noises occur while driving; the engine shakes, and the engine warning light comes on. Fueling Precautions: When refueling the car, avoid waiting until the fuel warning light comes on, as this can shorten the fuel pump's lifespan. The fuel pump is a critical component of the car's fuel supply system: If the fuel pump fails while the car is in motion, it can directly cause the vehicle to become immobile, operate poorly, or exhibit symptoms like labored acceleration.

What Damage Can Hail Cause to Cars?

Hail falling from high altitude carries significant kinetic energy and can be quite destructive. Even ordinary-sized hail can damage vehicles, causing harm to windshields and paint surfaces, with the extent of damage depending on the size of the hailstones. Below is a detailed introduction to the hazards hail poses to cars: When hailstones are relatively small: For example, the size of soybeans, the impact is minimal and typically does not cause damage to the car. Vehicles have a certain level of impact resistance, and in most cases, they remain unharmed unless the car body or glass quality is poor. When hailstones are larger: Such as the size of a one-yuan coin, some as big as eggs, or even tennis balls, these heavier hailstones can smash cars, leading to shattered glass, dents, and other body damage. Precautions during hailstorms: Try to park the car in a sheltered area, preferably in an underground parking lot. If the car must remain outdoors, covering it with a thick blanket can help minimize damage. When caught in a hailstorm with no place to take shelter, quickly move to the back seats of the car to avoid injury from potential windshield shattering.

What is the difference between P gear and electronic handbrake?

The difference between P gear and electronic handbrake lies in their functions: P gear is a common gear position in automatic transmission models, designed to lock the vehicle's axle when stationary on a slope. The electronic handbrake is a technology that achieves parking braking through electronic control, operating on the same principle as the mechanical handbrake—both utilize friction between the brake disc and brake pads to control parking braking. The only difference is that the control method has shifted from the traditional mechanical handbrake lever to an electronic button. Automatic transmission allows the driver to control the accelerator pedal according to driving needs, automatically shifting into different gears based on engine load and the vehicle's operating conditions.
