Which is Better for a New Car: Coating or Crystal Coating?

Why does the windshield washer fluid warning light come on when there is no shortage of fluid?

Lack of windshield washer fluid warning light is on because the windshield washer fluid warning sensor is damaged. Extended information: The role of windshield washer fluid: 1. Wetting, penetrating, and solubilizing: Surfactants usually have functions such as wetting, penetrating, and solubilizing, thereby playing a role in cleaning and removing dirt; the presence of alcohol and ethylene glycol can significantly reduce the freezing point of the liquid, thus playing an anti-freezing role and quickly dissolving frost. 2. Ensure clear vision: A single-molecule protective layer will form on the glass surface. This protective film can prevent the formation of fog droplets, ensuring that the windshield is clear and transparent, with a clear view. 3. Anti-static: After cleaning with windshield washer fluid, the substances adsorbed on the glass surface can eliminate the charge on the glass surface, providing anti-static performance. The windshield washer fluid contains ethylene glycol, which has a high viscosity and can play a lubricating role, reducing friction between the wiper and the glass and preventing scratches.

Can a C1 driver's license drive a right-hand drive car in Hong Kong?

A C1 driver's license can drive a right-hand drive car in Hong Kong, but it cannot be driven directly. You need to apply for a Hong Kong driver's license before you can drive. Here is more relevant information: 1. How to apply for a driver's license: Applying for a driver's license is also relatively convenient. You need to obtain an application form from the Hong Kong Transport Department, then pay the relevant fees, and you can drive a vehicle in Hong Kong. You can also handle it through an agent. 2. Relevant information about the C1 driver's license: (1) The C1 motor vehicle driver's license is one of the codes for motor vehicle driver's licenses. (2) The driving level of the C1 motor vehicle driver's license includes all the permitted driving models of C2, C3, and C4. (3) The C1 motor vehicle driver's license can drive micro passenger cars, light and micro cargo trucks, light, small, and micro special operation vehicles, and other related models.

Should You Use Internal or External Air Circulation When the Car Interior is Humid?

To dehumidify the car interior, use the internal air circulation mode. Internal circulation quickly removes moisture from the car, while external circulation allows humid outside air to enter, making dehumidification slightly slower. Therefore, to quickly defrost and dehumidify, simply turn on the internal circulation. Internal Circulation: The internal circulation mode of a car's air conditioning system draws air from inside the car into the air conditioning compressor, compresses it, and then blows it back into the car. Use internal circulation when the outside air quality is poor or heavily polluted, such as on dusty roads, in congested traffic, or near chemical plants where there are foul odors or unpleasant smells, to prevent outside air from entering the car. In summer, using internal circulation helps the air conditioning cool the car interior more quickly. External Circulation: The external circulation mode of a car's air conditioning system draws air from outside the car into the air conditioning compressor, compresses it, and then blows it into the car. Periodically turning on external circulation allows fresh air to enter the car. When there are many passengers inside, using external circulation helps maintain fresh air and prevents excessive humidity inside the car, which can cause windows to fog up.

Why Can't Gas Stations Refuel on Rainy Days?

During thunderstorms, gas stations cannot refuel because the fuel nozzle may introduce stray currents into the vehicle's fuel tank, which can increase the movement of unstable gasoline molecules, posing potential hazards such as fires or explosions. Below is relevant information about gas stations: 1. Introduction: A gas station is a retail facility that provides gasoline and oil for cars and other motor vehicles, typically offering fuel oil, lubricants, etc. Due to the flammable, volatile, leak-prone, and static-prone nature of petroleum products sold at gas stations, safety is the top priority. 2. Station Regulations: Smoking or open flames are strictly prohibited; carrying any hazardous materials into the station is forbidden; adding gasoline to a vehicle's carburetor or plastic containers is not allowed; all motor vehicles must be turned off while refueling; any activities that may generate sparks, such as vehicle repairs or striking metal objects, are prohibited within the station.

What does the preliminary test for Subject 1 mean?

Driving schools implement preliminary tests to demonstrate teaching quality and improve the pass rate at the official vehicle management office exams. Candidates must pass the preliminary test before being allowed to take the actual exam at the vehicle management office. This prevents unprepared candidates from directly taking the official exam and lowering the pass rate. Below is an introduction to the four examination subjects: 1. Subject 1: Also known as the theoretical test or driver theory test, it is part of the motor vehicle driver's license assessment. 2. Subject 2: Commonly referred to as the small road test, it includes five test items: reversing into a garage, parallel parking, stopping and starting on a slope, 90-degree turns, and curve driving. 3. Subject 3: Known as the large road test, it assesses road driving skills in the motor vehicle driver's examination. 4. Subject 4: Also called the theoretical test or driver theory test.

Should the Magotan 330 use 92 or 95 octane gasoline?

According to the official car manual recommendation, the Magotan 330 should use 95 octane gasoline. In addition to checking the appropriate gasoline grade in the car manual, you can also find it on the fuel tank cap, which will also be marked. Usually, the gasoline grade can also be determined based on the engine's compression ratio. Cars with an engine compression ratio between 8.6-9.9 should choose 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should choose 95 octane gasoline. However, with the use of some new technologies nowadays, the gasoline grade cannot be solely determined by the compression ratio. A high compression ratio can also be tuned to use lower octane gasoline because, apart from the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also come into play. Generally speaking, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If the Magotan 330 occasionally uses the wrong gasoline grade, simply switch back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower octane gasoline, using higher octane gasoline will not cause damage, but the increase in octane number will change the fuel's ignition point, leading to delayed combustion in the engine. This means the engine's power output and thermal efficiency will decrease, resulting in poorer performance as experienced by the driver. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. Because the octane number is too low, the lowered ignition point of the gasoline may cause premature ignition during the compression stroke. If combustion occurs before the spark plug ignites during the compression stroke, resistance will arise during the upward stroke. This resistance can make the engine run very unstably. If the knocking is imperceptible, it may only increase noise without significant damage to the engine. However, if noticeable knocking occurs, it indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on the pistons and cylinders, and in severe cases, cylinder scoring.
