What are the pros and cons of installing a rearview camera?

A rearview camera, also known as a parking assist system, reverse visual system, or vehicle monitoring system, is widely used in various large, medium, and small vehicles for reversing or driving safety assistance. The pros and cons of installing a rearview camera are as follows: 1. A rearview camera can effectively prevent scratches on the car, making reversing safer. 2. A rearview camera can easily handle various complex reversing environments. 3. It may void the warranty on the vehicle's wiring. 4. If the vehicle catches fire and subsequent inspection reveals that the cause of the fire is related to the wiring, the 4S shop may not be held responsible.

Can You Still Drive with a Shaking Car?

Normally, a car should run smoothly without significant shaking during operation. If you can clearly feel noticeable shaking, you can still continue driving as long as the warning light is not on, but you should drive at a lower speed and promptly take the car to a repair shop to diagnose the cause of the shaking. However, if the car shakes violently, produces unusual noises, and the warning light is on, you should immediately stop and call for assistance. Below are specific reasons for car shaking: 1. Engine Shaking: Issues such as carbon buildup, misfiring cylinders, or engine knocking can cause the engine to shake, leading to body vibration. When checking for engine-related shaking, also inspect the condition of the engine mounts, as one of their functions is to reduce the transmission of engine vibrations to the car body. 2. Brake Shaking: Brake shaking is often caused by grooved brake discs. You can feel obvious unevenness by touching the surface of the brake disc, and in severe cases, the edges of the brake disc may protrude significantly. Depending on the thickness of the brake disc, you can choose to machine it or replace it with a new one. 3. Gear Shift Shaking: Gear shift shaking may result from severely worn clutch plates or insufficient clamping pressure. This type of shaking caused by clutch issues is not noticeable during steady driving but becomes apparent during gear shifts or rapid acceleration. 4. High-Speed Shaking: High-speed shaking could be due to improper wheel balancing or abnormal tire wear. Wheel balancing refers to the even distribution of mass around the wheel's circumference; otherwise, the wheel will shake severely at high speeds. If the tire surface exhibits wave-like abnormal wear, it will not only cause shaking but also produce significant tire noise while driving.

Why Does the Engine Sound Louder After an Oil Change?

The reasons for a louder engine sound after an oil change include: 1. The oil viscosity does not match, which can easily lead to carbon buildup, causing the engine noise to increase. 2. The main function of the exhaust pipe is to expel exhaust gases and reduce engine noise. If there is an issue with the exhaust pipe, the engine noise will definitely change. 3. There are more and more counterfeit oil products on the market, so car owners should pay attention to the quality of the oil when purchasing. 4. Excessive oil can create significant resistance, affecting power output, increasing fuel consumption and carbon buildup, reducing engine power, and causing excessive noise.

How to Obtain a C4 Driver's License?

c4 driver's license is processed at the local vehicle management office and requires an examination. In some areas, the theoretical test for the c4 license has been delegated to district vehicle management offices, allowing applicants to obtain the license by passing the test at these offices. A c4 license permits the holder to drive three-wheeled motor vehicles (originally three-wheeled agricultural transport vehicles). Below are the contents of the C4 driver's license examination: 1. Subject 1: The test typically consists of answering 50 questions, with each question worth 2 points. The test duration is 45 minutes, and a passing score is 90. 2. Subject 2: Pole weaving test: The test site is set up with several iron poles, usually spaced three meters apart. The examinee must navigate a motorcycle in an S-shape through the poles back and forth once, without crossing the boundary lines or stepping on the ground with their feet during the ride. 3. Subject 3: The test mainly includes recognizing various road signs, understanding traffic police hand signals, and knowing how to handle different situations while riding a motorcycle.

What are the reasons for low pressure in car air conditioning?

Here are the reasons for low pressure in car air conditioning: 1. The opening degree of the expansion valve (or orifice tube) is too small. 2. Insufficient refrigerant in the system. 3. Blockage in the expansion valve or low-pressure side. 4. The compressor runs continuously, or the variable displacement fails. The following are the functions of car air conditioning: 1. It is used to adjust and control the temperature, humidity, air cleanliness, and air flow in the car compartment to the optimal state, providing a comfortable riding environment for passengers and reducing travel fatigue. 2. It creates good working conditions for the driver and serves as an important ventilation device to ensure safe driving.

Should Engine Oil Be Changed When It Turns Black?

Engine oil has a certain lifespan, limited by both time and mileage, and does not necessarily need to be changed just because it turns black. There are several methods to determine whether engine oil should be replaced: 1. Smell Test: Pull out the dipstick and smell it closely. If there is a strong sour or foul odor, it indicates the oil has deteriorated and should be changed. 2. Rub Test: Take out the old oil and rub it repeatedly between your thumb and forefinger. Good-quality oil will feel smooth, produce little grit, and cause no friction. If you feel impurities, poor viscosity, or even a rough texture, it should be replaced. 3. Color Test: Place a few drops of old oil on a clean white filter paper. After the oil seeps in, high-quality oil will leave no powder, feel dry and smooth to the touch, and show a clear yellow infiltration zone. If it appears dark brown or black with impurities, it should be changed. 4. Light Test: Hold the dipstick at a 45-degree angle under light to observe the oil droplets. If the droplets are clear with no visible grit, the oil is still good. If there is a lot of grit, it should be replaced.
