What Causes the Abnormal Noise When the Car Bumps?

Here are the specific reasons for the abnormal noise when the car bumps: 1. Shock absorber failure: Check if there are gaps in the shock absorber or if the suspension is faulty. If the shock absorber is leaking oil, it may be due to a faulty oil seal gasket, and the shock absorber needs to be replaced. Generally, the service life of a shock absorber is 80,000-100,000 kilometers. 2. Excessive clearance in the steering tie rod ball joint: There may also be abnormal noise when turning. In severe cases, steering wheel vibration and tire wear may occur. 3. Excessive clearance in the lower control arm: Or the lower control arm may be loose. The lower control arm connects the axle and the frame, helping to cushion the impact of bumpy roads on the car.

Can a car air conditioning compressor still be used if it's leaking oil?

It is recommended to replace the compressor. Here are the specific details: 1. Complex replacement: Replacing the compressor shaft seal is very complicated and requires specialized maintenance personnel from the compressor manufacturer to complete it using professional fixtures. Additionally, the compressor needs to be disassembled. If the shaft seal is damaged, the main shaft may also be affected. The chances of repairing internal compressor failures are relatively small, as most repair stations do not have genuine replacement parts or the necessary installation fixtures. 2. Relevant advice: After stopping the refrigeration system, start the compressor every two weeks for 3 to 5 minutes. The benefit of this is that the refrigeration oil is delivered to the shaft seal, preventing it from drying out and reducing its sealing effectiveness.

How much engine oil should be added to the Envision?

Envision's engine oil capacity is approximately 4.5L. After adding oil, you can check the oil dipstick for the exact level. Here are some related details: 1. Engine oil, also known as engine lubricant, serves multiple functions including lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the 'blood' of a car. 2. The oil dipstick is used to measure the static oil level height, indicating whether the engine oil level is within the proper range. Standard oil dipsticks have clear upper and lower limit marks, and as long as the measured oil level falls between these two marks, it is considered acceptable.

What are the symptoms of incorrect engine timing?

Incorrect engine timing can cause symptoms such as delayed ignition, poor acceleration, engine shaking, and insufficient power. It is recommended to visit a 4S shop to adjust the timing belt and restore vehicle performance. If the ignition is too late, it may cause difficulty in starting or insufficient power; if the ignition timing is too early, the engine may produce a metallic knocking sound (similar to "clattering") when suddenly accelerating during operation. Engine timing is divided into two types: 1. Valve timing refers to the timing mechanism (including the camshaft, valves, rocker arms, etc.) that supplies the combustible mixture to the cylinder at the correct time and exhausts the waste gas at the correct time; 2. Ignition timing refers to igniting the combustible mixture in the cylinder at the precise moment to drive the piston and perform work.

What is the difference between monochrome and color display screens in the car computer?

The difference between monochrome and color display screens in the car computer lies in their functionality: monochrome screens display some basic functions; color screens offer more media features and are more aesthetically pleasing with vibrant visuals. The car computer display screen generally refers to the screen on the dashboard, primarily showing the vehicle's current status information, such as instant fuel consumption and average speed. The difference between the car's central control screen and the car computer display screen is their location: the car's central control panel is positioned between the driver's seat and the front passenger seat for easy access by both the driver and passenger; the car computer display screen is located directly in front of the driver's seat for convenient observation by the driver.
