Is an Engine Not Being Broken Not Considered a Scrapping Standard?

Generally, when the vehicle reaches 10 years of age, even if the engine is not broken to the point of being irreparable, the vehicle management department will still enforce mandatory scrapping. Regarding engine repair: By replacing parts, the engine can be fixed, but the issue lies in the cost. Components like the cylinder block, cylinder head, crankshaft, and camshaft are relatively expensive, making the replacement costs quite high. Remanufactured engines involve repairing used engines through specific processes, allowing them to be reused with performance and power consumption differing by about 10% compared to original factory engines. Five bad habits that most easily lead to engine scrapping: Driving at high gear with low speed, adding excessive engine oil, using mismatched fuel grades, not warming up the engine or overheating it, and not replacing the timing belt in a timely manner.

Is a slightly deformed small car wheel hub a big problem?

A slightly deformed small car wheel hub can have significant impacts and is highly likely to cause direct fracture of the hub if it hits an obstacle while driving. About wheel hub material: Aluminum alloy, as a metal material, can be bent back into shape like a straightened wire, but after two or three attempts, it will break—let alone a large wheel hub. If the hub is forcibly restored to its original shape, it may look new externally, but its internal structure becomes very fragile. If the repaired area is impacted again during driving, the hub could fracture directly, leading to a serious traffic accident. Repair method: First, cushion the dented area with sponge or cloth, then use a hammer to forcefully flatten the dent. The flattened area will be uneven, so use body filler (commonly known as putty) to smooth it out. Afterward, roughen the inside of the hub with sandpaper to prepare for the next step—painting.

Can the Engine Be Restarted After Water Intake?

After a vehicle has been submerged in water, it is strictly prohibited to attempt a restart. The reasons are as follows: 1. Damage to the Engine Block: If the vehicle stalls during water submersion, it indicates that water has entered the engine. Since water is incompressible, the piston cannot reach its original top dead center position, resulting in a shorter piston stroke and a noticeable downward shift in the top dead center position. Attempting to restart the engine under these conditions can cause the piston connecting rod to bend, and in severe cases, damage the engine block, leading to irreparable harm. 2. No Compensation from Insurance Companies: Any damage caused by restarting the engine after water intake will not be covered by insurance. Moreover, attempting to restart the engine after water intake is a serious violation of insurance claim principles, making the claim ineligible. In such situations, the first course of action should be to push the vehicle out of the water, then call for roadside assistance or contact a nearby repair station to have the vehicle towed away for inspection and repairs.

Why does the display screen remain on after removing the car key?

There are two main reasons for this issue: first, the key switch may be faulty, causing the vehicle to remain in the power-on position without completely turning off the electrical appliances. Second, the power supply of the central control screen may be malfunctioning, preventing it from automatically shutting off. More relevant information is as follows: 1. Damaged central control screen power supply: If the central control screen does not turn off, it might be due to a damaged power supply, which requires immediate attention. Otherwise, the vehicle may fail to start the next day due to battery drain. 2. Five numeric dots appear on the central control screen: These dots are actually part of the screen calibration process and do not indicate damage to the vehicle. After prolonged use, the touch points on the screen may become less responsive, prompting the system to automatically display a "Screen Calibration" page. Simply tap the five dots on the screen in order, and the system will automatically calibrate the screen. After calibration, the touch points will return to normal. If the central control screen becomes unresponsive, you can also manually enter the screen calibration program to correct it.

What is the reason for the absence of manual mode in a semi-automatic transmission?

Semi-automatic transmission not having manual mode may be caused by a malfunction in the data program module information. Gear lever manual mode: This type of manual mode, operated through the transmission gear lever, is currently the most common. The specific method of use is to switch the transmission gear lever to M or S mode after the vehicle is started/while driving, and then shift gears by pushing the gear lever forward or backward. As long as the vehicle is in the started state, the manual mode can be engaged for gear shifting using the above method. If you need to switch back to D mode (automatic mode) while driving, simply move the gear lever from the manual mode position back to D mode. Steering wheel paddle shifters: Steering wheel paddle shifters can be understood as an extension of the manual mode. They are merely an "additional control method" added to vehicles that already have a manual mode. As a quick-shifting mechanism, paddle shifters are located behind the steering wheel, allowing the driver to shift gears without taking their hands off the wheel, making the operation more convenient and efficient.
