Should the Engine Be Turned Off and the Key Removed When Refueling a Car?

When refueling a car, it is necessary to turn off the engine and remove the key for the following reasons: 1. Electrical leakage may occur, which can easily cause a car fire. If the engine is not turned off, the vehicle's engine and some electrical equipment inside the car remain operational. During the refueling process, these electrical devices may experience electrical leakage, leading to a short circuit in the wiring. If sparks are generated, it can easily cause a car fire. 2. The vehicle's exhaust pipe continuously emits exhaust gases, which may produce sparks and cause an accident. When the engine is running, the exhaust pipe continues to emit exhaust gases. Besides the high temperature of the exhaust pipe, sparks may also be generated during exhaust emission. 3. The operation of electrical equipment inside the car generates heat, which can easily ignite the vehicle. The working of electrical equipment produces a significant amount of heat, causing the gasoline in the fuel tank to evaporate more quickly. When the concentration of gasoline vapor near the fuel tank reaches a certain level, any spark generated during the engine's operation can ignite the car, potentially even reaching the fuel nozzle and causing more severe consequences.

Is it harmful if windshield washer fluid splashes outside during refill?

It is harmless if windshield washer fluid spills out during refill. There will be no adverse effects or corrosion. Automotive windshield washer fluid is mainly composed of water, alcohol, ethylene glycol, corrosion inhibitors, and various surfactants. It primarily serves functions such as cleaning, antifreeze, antifog, antistatic, lubrication, and corrosion prevention. Below are specific details about windshield washer fluid: 1. Most inferior-quality windshield washer fluids are mixtures of water and alcohol, which not only damage the gloss of car paint and the hardness of rubber strips but may also cause color differences or swelling/dissolution in rubber or plastic components in severe cases. If washer fluid accidentally spills outside during refill, it may flow near the air conditioning intake. The volatile odor of the fluid can also enter the cabin through the car's air conditioning ventilation ducts. The gases emitted by inferior-quality washer fluids are harmful and can become hidden health hazards for car owners. 2. It is recommended to use high-quality windshield washer fluid. Premium washer fluids are made from deionized water and various eco-friendly additives, offering functions like dirt removal, antifreeze, antistatic, and corrosion prevention. Some superior-quality washer fluids even feature rapid snow/ice melting, antiglare, and antifog properties, significantly enhancing driving safety.

Why does the cooling fan keep running after the car is turned off?

It is normal for the cooling fan to continue running even after the car key is removed. Generally, it will stop after a few minutes. The purpose of the cooling fan is to dissipate heat from the engine. If the relevant sensors detect that the engine temperature is high, the cooling fan will start running. Even if the car key is removed, the fan will continue to operate because it is controlled by the car's computer, and it will keep running until the engine temperature drops to an acceptable level. Here is some relevant information: 1. The fan is not controlled by the key. The power for the cooling fan comes directly from the battery. As long as the battery has power and the engine temperature remains high, the fan will automatically run until the temperature decreases. Additionally, some owners may notice that the fan continues to run after removing the key and then try restarting and turning off the engine, only to find that the fan stops. This happens because the temperature thresholds for the engine-off state and the driving state are different. 2. When using the car, it is important to monitor the coolant temperature regularly. If the temperature becomes abnormally high, it is necessary to replace the coolant in time to avoid unnecessary damage to the engine. It is also essential to clean debris from the radiator periodically, as this affects the radiator's cooling efficiency.

Will the license be issued immediately after passing Subject 3?

No, you still need to take Subject 4. After passing the Subject 3 practical road skills test, you must complete the final subject, which is the Subject 4 theoretical test. Only after passing the Subject 4 theoretical test can you obtain your driver's license. Subject 4, also known as the Subject 4 theoretical test or driver's theoretical test, is part of the motor vehicle driver's license assessment. The main content includes: safe and civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident handling knowledge. Each driving school has different regulations. Some driving schools require students to collect the license themselves from the vehicle management office, while others may assist students by collecting it in advance and notifying them to pick it up directly from the driving school. After passing the test, applicants must receive no less than half an hour of traffic safety and civilized driving education, as well as accident case warnings. They must also participate in a license oath ceremony. The vehicle management office will issue the motor vehicle driver's license on the same day the applicant attends the oath ceremony. For those applying to add a permitted driving category, the original driver's license must be surrendered.

Can Shengsheng Return Trucks Accept Orders Without Stickers?

Shengsheng return trucks cannot accept orders without stickers. Here is some additional information about vehicle stickers: The annual inspection label must be displayed. The annual inspection pass label and compulsory motor vehicle insurance label must be affixed to the upper right corner of the front windshield. Failure to display the annual inspection label can result in penalties. According to Article 13 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," motor vehicle license plates must be hung in designated positions at the front and rear of the vehicle, kept clear and intact. Introduction to Shengsheng Return Trucks: Shengsheng Return Trucks is a logistics and truck-finding APP specializing in intra-provincial medium and short-distance full truckload, carpooling, and inter-provincial long-distance LTL (less-than-truckload) transportation services.

What is the difference between L and T engines?

There are the following differences between L and T engines: 1. The intake system of an L engine is naturally aspirated, while the intake system of a T engine is equipped with a forced induction system. 2. The main difference between these two engines lies in their working principles. Cars with the same displacement but equipped with a T engine tend to have more power. Naturally aspirated engines have a long history of use and development, and their technology is now relatively mature. They offer smoother power output, stability, and reliability, which are the advantages of naturally aspirated engines. As for turbocharged engines, they are essentially improved versions of naturally aspirated engines. The addition of a turbocharger enhances the power of small-displacement engines. However, while turbocharged engines provide strong power, they also come with certain drawbacks, such as increased fuel consumption and fluctuating power output (since the turbocharger only activates when the engine reaches around 1,500 RPM). The issues of unstable power output and higher fuel consumption in turbocharged engines have been significantly addressed by manufacturers through continuous technological advancements, reducing the abruptness and improving fuel efficiency. 3. In terms of manufacturing, naturally aspirated engines have relatively simpler production processes and are easier to maintain. On the other hand, turbocharged engines, due to their more intricate internal components, may incur higher repair costs if damaged.
