Is it allowed to drive at 60 km/h on the highway?

Is it possible to replace only one tire after 3000 kilometers?

It is not necessary to replace two tires after 3000 kilometers. If the tire wear is not severe, you can replace just one tire. Function of car tires: Car tires are one of the important components of a vehicle. They directly contact the road surface and work together with the car's suspension to mitigate the impact during driving, ensuring good ride comfort and smooth driving. They also ensure good adhesion between the wheels and the road surface, improve the vehicle's traction, braking, and off-road capability, and bear the weight of the car. The important role of tires in vehicles is increasingly recognized. Tire classification: Tires can be classified by size into full-size tires and non-full-size spare tires. Full-size tires: Full-size spare tires have the exact same specifications as the other four tires on the vehicle and can replace any temporarily or permanently unusable tire. Non-full-size tires: These spare tires have slightly smaller diameter and width compared to the other four tires, so they can only be used temporarily and should only be installed on non-driving wheels. Additionally, the maximum speed should not exceed 80 km/h.

What are the maintenance methods for pure electric vehicles?

The maintenance methods for pure electric vehicles are: 1. Correctly grasp the charging time; 2. Protect the charger; 3. Charge daily; 4. Periodically perform deep discharge of the battery; 5. Avoid power loss during parking; 6. Avoid high-current discharge. Pure electric vehicle models include: NIO ES6, Junfeng E17, GAC GE3, Zotye Cloud 100, BYD Qin, etc. Taking the 2020 NIO ES6 as an example, it belongs to a mid-size SUV with body dimensions of: length 4850mm, width 1965mm, height 1758mm, and a wheelbase of 2900mm. The 2020 NIO ES6 is equipped with a permanent magnet motor, with a maximum power of 160kW and a total motor torque of 610Nm, paired with a single-speed fixed gear ratio transmission.

What is the white smoke from car exhaust?

White smoke from car exhaust is caused by water in the cylinders, which produces white smoke when expelled. Low temperature can generate white smoke: When starting the car at low temperatures, white smoke is a common phenomenon, especially during cold starts on winter mornings. This is not a malfunction but occurs because the metal cylinder walls are colder in winter. The heat generated by the engine causes water droplets to form on the cylinder walls, and white smoke is naturally produced during combustion. This condition disappears once the engine warms up. Cylinder head gasket damage can produce white smoke: After normal combustion of gasoline, water and carbon dioxide are produced. When water encounters high temperatures, it turns into steam, which condenses into water mist upon encountering cold air in the exhaust system, appearing as white smoke. This is a normal phenomenon. However, if the exhaust pipe continues to emit white smoke even after driving for over ten minutes, it indicates a damaged cylinder head gasket. If water enters the cylinders, white smoke will also appear because a damaged cylinder head gasket compromises the seal between the cylinder block and cylinder head, allowing water to enter. The water in the cylinders turns into steam under high temperatures. A damaged cylinder head gasket is a serious issue and requires replacement by the car owner.

Is It Normal for the Transmission to Make a Clicking Sound?

The presence of a clicking sound in the transmission is an abnormal phenomenon. Its functions include: 1. Changing the transmission ratio; 2. Expanding the torque and speed of the driving wheels; 3. Enabling the vehicle to reverse; 4. Facilitating gear shifting or power output in the transmission. Transmission maintenance methods: 1. Replace automatic transmission fluid every 12 months or 20,000 kilometers; 2. Avoid coasting in neutral; 3. Regularly check the fluid level; 4. Avoid skipping gears when upshifting; 5. Do not force the transmission into neutral; 6. Do not shorten the idle warm-up time; 7. Avoid gear grinding when shifting; 8. Clean the transmission; 9. Do not start driving immediately without warming up the vehicle; 10. Perform regular maintenance on the automatic transmission. The causes of clicking sounds in the transmission include: 1. Wear and damage to bearings; 2. Wear of transmission components or the use of low-precision replacement parts; 3. Insufficient or overly viscous lubricant leading to poor lubrication; 4. Loose bolts on the transmission housing.

How to Read the Water Temperature Gauge in a Car?

The method to read the water temperature gauge in a car is to observe the position of the gauge's needle. The water temperature gauge uses 'C' to 'H' to indicate the water temperature, where 'C' represents 60 degrees and 'H' represents 110 degrees. The normal temperature range is between 80 and 100 degrees. When the engine's water temperature rises into the high-temperature zone, the water temperature gauge will light up. In this case, you should stop the car and let it idle for 5 minutes before turning off the engine. Wait until the water temperature indicator returns to the normal state before restarting the car to continue driving. Reasons for high engine water temperature: 1. Insufficient coolant – a lack of coolant leading to high water temperature is quite common; 2. Problems with the cooling fan – issues with the engine's cooling fan can also cause the engine water temperature to rise; 3. Issues with the circulation water pump – if the water pump malfunctions, the water circulation on the engine's heat conduction side cannot proceed normally, resulting in high water temperature. It is important to detect and resolve these issues early to avoid more significant failures.

What Causes Loud Abnormal Engine Noises?

Engine abnormal noise is loud because the foot pad is damaged and aged after long-term use. Engine: An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. The engine is suitable for both power generating devices and the entire machine including the power device (such as gasoline engines, aircraft engines). The engine was first born in the UK, so the concept of the engine also comes from English, and its original meaning refers to "mechanical devices that generate power". Engine abnormal noise: The engine is the heart of the car and needs to withstand long-term and high-load work. Over time, the internal parts of the engine will inevitably experience wear and aging. The most direct phenomenon of component failure is the engine making various abnormal noises during operation. Compared with the abnormal noise of accessories installed outside the engine, the abnormal noise inside the engine cylinder is slightly more difficult to determine the source of the fault because it cannot be visually observed and inspected.
