Is driving at 140 km/h harmful to a new car?

Driving at 140 km/h can be harmful to a new car. During the break-in period, it is generally recommended not to exceed 100 km/h on highways. Driving tips: When driving, it is also important to avoid sudden acceleration or flooring the gas pedal. Wait until the vehicle reaches normal operating temperature before engaging in aggressive driving. As long as this driving style is not sustained over long periods, it usually won't cause significant damage to the vehicle. Break-in period introduction: The break-in period, also known as running-in, refers to the initial driving phase for a new car or a major overhauled vehicle, typically covering 1000~1500 kilometers. This mileage is essential for ensuring proper contact, friction, adaptation, and stabilization of mechanical components.

What Causes a Small Truck's Air Conditioning to Not Cool?

The following are the specific reasons why a small truck's air conditioning may not cool: 1. Insufficient or low refrigerant: This may be caused by a minor refrigerant leak. You can observe this through the sight glass on the dryer tank. When the air conditioning is running normally, if continuous bubbles appear in the sight glass, it indicates insufficient refrigerant. If obvious bubble flipping occurs, it indicates a severe lack of refrigerant, and adding refrigerant will solve the issue. 2. Loose drive belt of the car air conditioning compressor: If the drive belt is loose, the compressor may slip during operation, leading to reduced transmission efficiency and a drop in compressor speed. This results in decreased refrigerant compression and delivery, causing the air conditioning to not cool. If the compressor drive belt is too loose, it should be tightened. If it cannot be turned by hand, the belt is too tight and should be slightly loosened. If tightening is ineffective or the belt shows cracks, aging, or other damage, a new drive belt should be installed.

What are the causes of crankshaft oil seal detachment?

Crankshaft oil seal detachment may be caused by the failure to use non-petroleum-based lubricants during the pressing process, or the parallelism between the rear oil seal pressing surface and the rear oil seal seat mounting surface not meeting the technical requirements of the assembly drawing. Failure to use non-petroleum-based lubricants during the pressing process: If non-petroleum-based lubricants are not used during the pressing of the crankshaft oil seal, the oil seal may become loose or even detach after the engine has been in use for some time (for example, some engine manufacturers may use engine oil instead of relatively expensive non-petroleum-based lubricants to reduce production costs). Parallelism between the rear oil seal pressing surface and the rear oil seal seat mounting surface not meeting technical requirements: This can lead to uneven deformation of the rear oil seal lip due to uneven force distribution. After the engine has been in use for some time, the oil seal lip may deform or the entire seal may twist, resulting in oil seal failure and engine oil leakage.

Why does the newly replaced battery charger always fail to fully charge?

The newly replaced battery charger may fail to fully charge due to reasons such as insufficient charger current, excessively high charging environment temperature, or mismatched charger parameters with the battery. Insufficient charger current: The charging time is prolonged, and the battery cannot be effectively fully charged within the expected time, causing the charger not to switch off the indicator light. Excessively high charging environment temperature: When the charging environment temperature exceeds 45 degrees Celsius, the charging voltage at the battery terminal cannot reach the limited voltage value, and the charging current remains at a high level, failing to drop to the inflection point current value, thus preventing the charger from switching off the indicator light. Mismatched charger parameters with the battery: This leads to long-term overcharging or undercharging of the battery, eventually causing water loss in the battery and preventing the charger from switching off the indicator light.

Can a Tablet Be Installed on the Car's Central Console?

A tablet cannot be installed on the car's central console. The reason is that the car's infotainment system operates in a harsh environment, directly affected by temperature fluctuations and vibrations. While the vehicle body provides external protection, the temperature variations are significant. However, the car's infotainment system must be capable of starting in low temperatures, operating normally in high temperatures, and ensuring that its components remain undamaged on bumpy roads. Its reliability and durability requirements are higher than those of any other electronic product. Door Lock Switch: Most central console switches consist of a master switch and sub-switches. The master switch is installed on the driver's side door, while the sub-switches are installed on other doors, allowing individual control of each door. Door Lock Actuator: The central locking actuator is used to execute the driver's commands, either locking or unlocking the doors. Door lock actuators come in three types: electromagnetic, DC motor, and permanent magnet motor. All these mechanisms change polarity to reverse their movement direction, thereby performing the locking or unlocking action. Door Lock Controller: The door lock controller is the control device that provides the actuator with pulsed current for locking or unlocking. Regardless of the actuator type, the direction of the current is reversed to move the linkage left or right, achieving the lock or unlock function.

Is It Normal for Summer Tires to Exceed 60 Degrees?

It is normal for summer tires to operate between 90-110 degrees Celsius, and a tire temperature of 60 degrees will not affect driving. Preventing excessive tire temperature: To control tire temperature from getting too high, the first step is to manage driving speed. When a vehicle moves at high speeds, most of the kinetic energy is absorbed and converted into heat, causing the tire temperature to rise. This accelerates rubber aging and reduces the fatigue resistance of the cord layers, leading to early tire separation or blowouts. Therefore, limiting driving speed is crucial for controlling tire temperature. Impact of summer driving on tires: In summer, road surface temperatures often exceed 70 degrees Celsius. Driving in hot weather makes it difficult for tires to dissipate accumulated heat due to high external temperatures, causing a rapid rise in tire temperature and an increase in internal pressure. This accelerates rubber aging, leading to cord layer separation or blowout damage. Hence, extra attention should be paid to controlling tire temperature and driving speed during hot weather.
