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.

What is the function of car coolant?

The function of car coolant is to carry away excess heat generated during engine operation, allowing the engine to operate at normal working temperature. Insufficient coolant: When coolant is insufficient, the engine will overheat during operation, leading to damage of engine components. In severe cases, it may cause engine burnout or spontaneous combustion. Therefore, once insufficient coolant is detected, it should be replenished promptly. Additionally, after 6 years of vehicle use, the coolant should be inspected or replaced. Composition of coolant: Engine coolant is not ordinary water but a solution composed of base fluid and water. Due to the requirements of modern automotive technology, various additives are included to address issues such as cavitation, chemical corrosion, electrochemical corrosion, and scale formation, thereby protecting different types of engines. Since the chemical compositions of additives like rust inhibitors and antifoaming agents vary among different types of coolant, they should not be mixed. For example, coolants used in Japanese car models generally contain phosphates but strictly exclude silicates and nitrite additives.

Why is the car air conditioning not cooling but not short of refrigerant?

The reasons why the car air conditioning is not cooling but not short of refrigerant are as follows: 1. Quality and purity of refrigerant: The quality and purity of refrigerant play a crucial role in the operation of the car air conditioning system. Usually, inferior refrigerant will lead to low efficiency of the air conditioning system. 2. Condenser and radiator: The heat dissipation condition of the condenser and radiator will also affect the performance of the air conditioning. If not cleaned for a long time, the condenser and radiator may be covered by dust and debris. 3. Usage of refrigerant: Many car owners believe that the more refrigerant in the air conditioning system, the better. However, this is not the case. During the refrigerant charging process, the amount of refrigerant should be neither too much nor too little. Too little refrigerant will result in insufficient pressure in the air conditioning pipes, while too much will cause excessive pressure. In both cases, the air conditioning system cannot operate normally to provide cooling. 4. Quality of the expansion valve: The expansion valve is an important component in the refrigeration system, usually installed between the liquid storage tank and the evaporator. An inferior expansion valve will prevent the refrigerant from functioning as it should.

Are High-Speed Charging Piles Widely Available?

No. Not all highway service areas have charging piles, and they are not yet fully widespread. In recent years, the government has been vigorously constructing new energy vehicle charging piles to address the current charging issues for such vehicles. Additional details are as follows: 1. Function of Charging Piles: Similar to fuel dispensers at gas stations, charging piles can be fixed on the ground or walls and installed in public buildings (such as office buildings, shopping malls, public parking lots) and residential community parking lots or charging stations. They can charge various types of electric vehicles according to different voltage levels. The input end of a charging pile is directly connected to the AC grid, while the output end is equipped with a charging plug for electric vehicles. Charging piles (or charging posts) can implement timed charging, metered electricity usage, and cost calculation, serving as public terminals for purchasing electricity. 2. Charging Methods: Charging piles generally provide two charging methods: regular charging and fast charging. Users can swipe specific charging cards on the human-machine interaction interface provided by the charging pile to select the charging method, charging time, print cost data, etc. The display screen of the charging pile can show data such as charging amount, cost, and charging time.
