Should the Engine Be Turned Off When Refueling a Car?

What is the reason for engine shaking at idle but not when accelerating?

The reasons for engine shaking at idle but not when accelerating are: 1. Changes in fuel injection volume; 2. Malfunction in the fuel pump pressure regulator or sensors causing faulty fuel injection correction signals; 3. Cracked vacuum booster pipe; 4. Carbon buildup or dirt on the throttle body, or incorrect positioning of the throttle position sensor. The connection points between the engine and the frame are equipped with engine mounts, which absorb vibrations generated during engine operation. An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, electric motors, etc. Idling results in low engine speed, which can propel the vehicle forward under light load conditions.

What does the tire pressure warning light with an exclamation mark mean?

Tire pressure warning light with an exclamation mark indicates that the tire pressure is either too low or too high. The normal tire pressure range for car tires is between 2.2 and 2.5. Excessive tire pressure concentrates the vehicle's weight on the center of the tread, leading to rapid wear in that area. Insufficient tire pressure can cause uneven tire contact with the road surface, increased wear, higher rolling resistance, and greater fuel consumption. Tire pressure refers to the air pressure inside the tire. In automotive maintenance, the engine is considered the heart of the car—its failure can lead to the end of the vehicle's life. Similarly, tire pressure is like the blood pressure of the car, playing a crucial role in the vehicle's performance and power.

Does having different tire tread patterns front and rear affect the car?

Tire tread patterns being different front and rear can affect the car, with specific impacts including: 1. It can affect the service life of the tires and lead to increased fuel consumption; 2. It can cause an imbalance in the grip of the four tires, making the car prone to skidding or veering while driving, and posing a risk of side slipping in rainy conditions, which is a safety hazard; 3. It can affect the comfort of the car's ride. The main function of tire tread patterns is to prevent slipping, ensuring driving safety, braking, shock absorption, and smooth changes in driving direction. Tires are generally composed of three parts: the outer tire, inner tube, and flap. The inner layer of the tire has a rubber layer with excellent air tightness, gradually moving towards lighter weight. The outer tire mainly consists of the carcass, tread, sidewall, and bead, with the carcass and bead forming the force-bearing structure of the car's pneumatic tires.
