What Causes Car Vibration?

How to judge the distance between cars for beginners?

Methods for beginners to judge the distance between cars: 1. The left one-third of the left rearview mirror and the right half of the right rearview mirror are danger zones for the following car; 2. If the following car is directly behind, when the inner rearview mirror can no longer see the wheels of the following car, it means the distance is less than 20 meters, and sudden braking should be avoided; 3. When the front of the car just touches the edge of the front car's tire, the distance should be about 5 meters; 4. When the front of the car aligns with the lower edge of the front car's bumper, the distance should be about 3 meters; 5. When the front of the car aligns with the front car's bumper, the distance should be about 1 meter; 6. If the front of the car aligns with the lower edge of the front car's license plate, the distance should be about 0.5 meters.

How Many Liters of Transmission Oil Should Be Added?

Transmission oil should be added approximately 4 liters. When replacing the transmission oil, the oil filter screen should also be replaced simultaneously. Precursors to transmission oil replacement include: 1. Vehicle shaking and gear shifting jerking; 2. The dashboard displays a transmission high-temperature warning; 3. The car stalls; 4. Unusual noises occur. The functions of transmission oil are: 1. Keeping the gear shifting system clean; 2. Lubricating the transmission device. Problems that may arise from insufficient transmission oil include: 1. Jerky gear shifting and unsmooth gear changes; 2. When pressing the accelerator, the increase in RPM does not correspond proportionally to the increase in speed—RPM increases normally, but the speed does not rise; 3. Severe cases may lead to transmission overheating and damage, as bearings lack lubrication, increasing the friction factor and making them prone to damage; 4. Noticeable noise, especially when driving at high speeds.

What are the differences between high-power and low-power engines?

Differences between high-power and low-power engines: 1. Different lifespan: The higher the engine power, the shorter its lifespan. Under the same model, the hardware structure of the engine is completely identical. The difference in power is actually determined by the turbocharger's boost intensity to achieve different power outputs, which results in higher fuel consumption and higher maintenance costs in the long run. Low-power engines have a longer lifespan, relatively lower fuel consumption, and lower maintenance costs. 2. Different prices: There is a significant price difference between low-power and high-power versions of the same model. Intuitively, low-power versions are relatively cheaper, while high-power versions are more expensive. 3. Different power: Drivers may feel a lack of power with low-power engines. From the perspective of engine wear, the difference in wear between the two is not significant. Although high-power engines deliver higher performance, the quality standards for engine component materials are also improved to handle prolonged high-load conditions.

How to Install Frameless Wipers?

Installation method for frameless wipers: Press the lower part of the wiper buckle, flip the buckle open, hook it onto the wiper mounting base, and then close the wiper buckle. If there are oil, wax, dirt, or other foreign substances on the windshield, clean them thoroughly before use. Frameless wipers are composed of four components: the wiper rubber blade, the frameless wiper steel strip, the wiper cover, and plastic parts. Wiper maintenance methods: 1. When using the wipers to remove dust from the windshield on sunny days, always spray windshield washer fluid and avoid dry wiping; 2. If there are stubborn or hard contaminants on the glass, clean them manually first; 3. When lifting the wiper blades during car washing or routine cleaning, hold the spine of the wiper blade and gently return it, avoiding snapping it back abruptly; 4. In winter, use an ice scraper to remove ice chips from the windshield surface first to prevent overburdening the wipers.

What Are the Precautions for Car Body Cleaning?

Precautions for car body cleaning: 1. Avoid using water other than soft water, including hot water, alkaline water, and water with high hardness, as these substances can damage the paint. Using hard water for cleaning may leave marks and a film on the car body surface after drying; 2. Avoid using high-pressure water flow to wash the cab of a suction truck, as excessive water pressure can damage the car body paint. If there is stubborn dirt on the car body, soak it with water first and then rinse it off, using a dispersed water flow for spraying; 3. Avoid randomly adding cleaning agents. Do not use laundry detergent, scouring powder, or inferior soap during cleaning, as these cleaning agents contain alkali, which may wash away the oils in the paint and accelerate paint aging. Generally, no cleaning agents are added when washing the car; 4. Avoid touching the car body surface with dirty hands stained with oil or placing oily tools or cloths containing organic solvents on the car body, as this can easily leave marks on the paint or cause the paint to fade prematurely.

What Causes Abnormal Noise During Engine Idling?

Engine idling with abnormal noise can be attributed to the following reasons: 1. Excessive carbon deposits: When there is too much carbon buildup on the throttle body, fuel injectors, or intake manifold, or when excessive carbon deposits accumulate inside the engine, the gasoline injected by the cold start injector can be largely absorbed by the carbon deposits. This results in an overly lean air-fuel mixture during cold starts, causing engine vibration. 2. Low cylinder pressure: After prolonged use of the engine, the gap between each cylinder liner and piston may become inconsistent. During cold starts, without proper lubrication from engine oil, cylinders with larger gaps are prone to leaking a certain amount of high-temperature gas from the gaps. This reduces power output, leading to low oil pressure and cylinder pressure, which in turn causes insufficient power and engine vibration. 3. Faulty ignition coil: If the ignition coil malfunctions, such as cracking and leaking electricity, it can result in insufficient or lack of spark plug ignition capability. Consequently, the air-fuel mixture in that cylinder will not combust properly, leading to engine misfire, difficulty starting, and acceleration vibration.
