Can the Fuel Pump Be Cleaned?

The fuel pump can be cleaned, as it is a crucial component for a vehicle. The fuel pump determines whether the car operates normally. If the pump becomes too dirty, it may lead to issues such as poor circulation and increased fuel consumption. Therefore, cleaning the fuel pump is necessary. More details are as follows: 1. Fuel pumps can be categorized into injection-type and self-priming-type. The injection pump is mainly used in car engines to ensure the diesel engine's low-speed and high-speed operation limits, maintaining a relative balance between fuel injection and rotational speed. 2. After starting, the self-priming pump's impeller rotates at high speed, directing water flow into the volute casing. Water then enters the pump, completing the self-priming process. 3. Vehicles have very high requirements for fuel pumps. Generally, fuel pumps are produced by a few specialized manufacturers worldwide and are highly precise and essential components of a car.

Is it necessary to press the brake when starting an automatic transmission car?

Starting an automatic transmission car requires pressing the brake. The specific reasons are explained below: 1. When starting an automatic transmission car, it is essential to press the brake. If the brake is not pressed, the car will not start. This is a specially designed feature to prevent the car from lurching forward or rolling backward during ignition. 2. Additionally, the gear of an automatic transmission car must be in P (Park) or N (Neutral) to start. If the car could start in N without engaging the handbrake or pressing the brake, it could roll, making the requirement to press the brake a safer design.

Can a car with a spare tire run on the highway?

It is possible to drive on the highway with a spare tire installed, but for non-full-size spare tires, the speed should not exceed 80 km/h. The usage methods for various types of spare tires are categorized as follows: 1. Full-size spare tires have no restrictions on mileage or speed and can replace any temporarily or permanently unusable tire. Since full-size spare tires have the same dimensions as the original tires, there is no need for concern. 2. Non-full-size spare tires can only be used on non-driving wheels, and the maximum speed should not exceed 80 km/h. This is because these spare tires have slightly smaller diameters and widths compared to the other four tires and are only intended for temporary use. 3. Run-flat tires (commonly known as "anti-burst tires") do not lose air or lose air very slowly when punctured. They can maintain their driving profile, and the tire bead remains fixed to the rim, ensuring the car can drive stably for an extended period or temporarily to a repair station.

Why does the car shake at low speeds?

There are several main reasons why a car may shake at low speeds: 1. Toe-in: Due to collisions during driving, the steering tie rod and steering cross rod may deform, various ball joints may wear out and become loose, or tire wear may become irregular, causing the toe-in to increase or decrease. 2. Wheel dynamic balance: After driving a certain distance, the original wheel dynamic balance weights may be lost, or the wheel hub may deform, causing the front of the car to sway and the steering wheel to shake at high speeds. 3. The lateral push rod ball joint may be loose or the bracket may be loose, leading to unstable driving. 4. The wheel hub bearings may be loose, and the left and right steering knuckle ball joints may be severely worn, causing inaccurate front wheel alignment.

What Causes Abnormal Noises After Starting the Car?

Abnormal noises after starting the car can be attributed to the following main reasons: 1. Aging or loosening of engine mounts: Engine mounts are rubber blocks placed between the engine and the car frame. Their purpose is to reduce vibrations and provide cushioning during engine operation, as well as to secure the engine in place. Once these mounts age or become loose, the engine may start to shake, resulting in abnormal noises. 2. Engine misfire noise: An engine misfire mainly refers to one or more cylinders not functioning properly. This is usually characterized by noticeable intermittent exhaust gas flow and severe shaking of the exhaust pipe, which is often related to faults in the ignition coil.
