Engine buzzing noise may be caused by engine failure or exhaust pipe leakage. Here are the specific details: 1. One situation that can cause engine buzzing is when the car is in the wrong gear while driving. A mismatch between the car's speed and gear can lead to engine buzzing, but this is not an engine fault. The noise will disappear when the car's speed matches the gear. 2. During driving, the engine's load increases, requiring the throttle opening to be increased and more fuel to be supplied. If the throttle is dirty or not opened to the optimal position, it can result in poor mixture ratio inside the engine, causing a buzzing noise during acceleration.

What are the effects of disconnecting the negative terminal of a car battery?

Disconnecting the negative terminal of a car battery will cut off all power to the vehicle, making it unable to start. Below is an introduction to car batteries: 1. Introduction: A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. 2. Classification: Car batteries are divided into conventional lead-acid batteries, dry-charged batteries, and maintenance-free batteries. Typically, when people refer to a car battery, they mean a lead-acid battery. The normal service life of a car battery ranges from 1 to 8 years, depending largely on the condition of the vehicle. 3. Principle: It uses lead plates filled with sponge lead as the negative electrode, lead plates filled with lead dioxide as the positive electrode, and 22-28% dilute sulfuric acid as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy.

How often should the tires on the Volkswagen Tayron be replaced?

The tire replacement cycle for the Volkswagen Tayron is 60,000 to 100,000 kilometers. Most original tires are from the Hankook brand, while some use Maxxis and Dunlop. The tire sizes vary according to the configuration, including 215/65-R17, 235/55-R18, and 235/50-R19 models. Below are the steps to replace the tires on the Volkswagen Tayron: 1. Park the vehicle on a level surface. If a breakdown occurs on the road, place a safety warning sign at least 150 meters behind the vehicle. Use a specialized tool to remove the tire nuts, loosening them in a diagonal sequence. 2. Position the jack directly under the support point and slowly raise the vehicle. Once lifted to a sufficient height, the tire can be removed. If the tire is tightly fitted and difficult to remove, a few firm kicks may help. 3. Install the new tire and manually secure the nuts. Tighten the nuts with a specialized tool, again using a diagonal tightening sequence. Only after the vehicle is lowered and the tire touches the ground should the nuts be fully tightened.

Is it normal for the Roewe RX5 oil dipstick to be at the third mark when the engine is cold?

It is normal for the Roewe RX5 oil dipstick to be at the third mark when the engine is cold. There is an upper limit and a lower limit. Checking the oil dipstick is simple: park the car on a level surface, turn off the engine, pull out the oil dipstick, and when the engine is cold, the oil level should be above 3/4 of the way between the upper and lower marks. Here is some relevant information: 1. The oil dipstick is accurate whether checked when the engine is cold or hot. When the engine is cold, the oil level should be above 3/4 of the way between the upper and lower marks, and when the engine is hot, the oil level should be above 1/2 of the way between the upper and lower marks, indicating sufficient oil. 2. When checking the oil dipstick with the engine cold, it shows the total oil capacity, while when checked with the engine hot, it shows the amount needed to meet the engine's lubrication requirements.

Solutions for Rear Displacement of the Right Front Wheel After a Collision

After the collision, perform a thorough re-inspection and realign the steering. The methods for tire maintenance are as follows: 1. Perform wheel alignment and tire rotation: Conduct wheel alignment and tire rotation every 10,000 kilometers traveled. 2. Check tire pressure: Tire maintenance also includes regular pressure checks. Tires exceeding the specified pressure will significantly reduce their lifespan, while tires below the specified pressure can lead to poor braking performance, difficulty or heaviness in steering, and also reduce tire lifespan. 3. Pay attention to the tread wear indicators: The tread wear indicators are located in the main drainage grooves of the tire and appear as trapezoidal rubber protrusions. When the tire tread wears down to the level of the wear indicators, the tire must be replaced. During the rainy season, to prevent the vehicle from slipping on wet roads, the tire tread depth must be maintained at least 3mm. 4. Inspect tire condition: Regularly check the tires to promptly identify issues such as bulges, cracks, cuts, punctures, valve rubber aging, and abnormal tire wear. Pay special attention to inspecting the wear on the tire tread and edges.

What is the ground clearance of the Vezel?

The ground clearance of the Vezel is 170MM. The Vezel adopts a front MacPherson suspension structure, which is a mainstream suspension layout. Its advantages include occupying less space, which is beneficial for the layout of the engine compartment, and the lower control arm is made of steel. The front suspension subframe is a full-frame steel subframe, equipped with an engine underguard and an aluminum heat shield in the engine compartment. The lower control arm is connected to the subframe via rubber bushings. More details are as follows: 1. Generally, the ground clearance of a sedan should be between 130mm and 200mm, ensuring that it doesn't scrape the chassis when encountering small bumps. However, overall, the ground clearance of sedans is relatively low, mostly below 150mm. 2. According to relevant regulations, the minimum ground clearance refers to the distance from the lowest point of the chassis (excluding wheels and suspension) to the ground when the vehicle is fully loaded and stationary. In fact, the height of the chassis has both advantages and disadvantages. Vehicles with higher ground clearance, such as full-size SUVs, have better off-road capability, while sedans with lower ground clearance are more prone to scraping the chassis.

How to Reverse Without a Backup Camera?

Here are the steps to reverse without a backup camera: 1. Find a suitable parking spot. Then drive forward parallel to the car in front, maintaining a distance of about one to one and a half steps (approximately 50~80 cm) from the adjacent car until your vehicle aligns with the B-pillar of the neighboring car. 2. Shift into R gear and quickly turn the steering wheel fully in the corresponding direction. Reverse until your car is at about a 45-degree angle to the parking space, which is usually when you can see the license plate of the rear car in the left side mirror. 3. Quickly straighten the steering wheel and continue reversing straight. During this process, pay attention to the rearview mirrors. 4. When the front of your car aligns with the rear of the car in front, quickly turn the steering wheel fully in the opposite direction and continue reversing. Open the window to observe and guide the left rear wheel into the parking space. 5. Once the left front wheel enters the parking space, straighten the steering wheel. Then adjust the car's position as needed.
