Here are the solutions for foggy windows when using the car heater: 1. First, set the air conditioning to the heating mode, press the AC button to activate the compressor, turn on the internal circulation, and direct the airflow toward the windshield. 2. After the fog clears, turn off the compressor. At this point, only hot air will be blowing. After a few minutes, fog may reappear on the glass. Reactivate the compressor and repeat this process 3-5 times. After that, you won't need to use the compressor anymore, and the windows will remain fog-free. 3. Adjust the temperature to a suitable level. Whether to use internal or external circulation afterward depends on whether the surrounding environment affects window fogging.

What is the original spark plug model for Dongfeng Peugeot 408?

Dongfeng Peugeot 408's original spark plug is NGKILZFR5B, and SUNIEDIRIT03 three-pin needle spark plugs can also be used. The spark plug is an important component of the gasoline engine ignition system, which introduces high voltage electricity into the combustion chamber and makes it jump across the electrode gap to generate sparks, thereby igniting the combustible mixture in the cylinder. The spark plug mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. The Dongfeng Peugeot 408 is the first model developed by Dongfeng Peugeot after introducing the EMP2 modular platform. The vehicle has a length, width, and height of 4750 mm, 1820 mm, and 1488 mm respectively, with a wheelbase of 2730 mm. In terms of appearance, the front face design of the Dongfeng Peugeot 408 is inspired by the iconic Lion's Eye headlights, integrated with the engine hood, presenting a bright and penetrating look, strongly reflecting the Peugeot brand image.

How long is the interval between Subject 3 and Subject 4?

After passing Subject 3, there are three scenarios for the Subject 4 exam schedule: 1. Taking the exam directly on the same afternoon; 2. No appointment required within 9 days—you can take the Subject 4 exam at the designated location by presenting your ID within 9 days of passing Subject 3; 3. Scheduling after 10 days, with successful appointment depending on factors such as current exam volume, student priority, and temporary arrangements at the test center. The specific scenario depends on the driving school's arrangements. Subject 4, also known as the theoretical exam or driver's theory test, is part of the motor vehicle driver's license assessment. It primarily covers: safe and civilized driving requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident procedures. The Subject 4 exam consists of 50 questions, primarily in the form of case studies, images, and animations, with a full score of 100 and a passing grade of 90.

What does the 4S in a 4S store mean?

It refers to a four-in-one automobile sales department, which includes vehicle sales channels, retail parts sales, vehicle after-sales service, and comprehensive information feedback. The full name is Automobile Sales Service 4S Store, which emerged in 1998 and originated in Europe, offering relatively comprehensive services and strict management. Below is an introduction to 4S stores: 1. Business scope of 4S stores: In a region, there will be several 4S stores for a brand, mainly determined by the scale of the city. There is competition among each 4S store, even though they belong to the same brand. According to the current situation in China, standard 4S stores only exist in cities and above, while some county-level cities do not have automobile 4S stores. 2. Characteristics of 4S stores: They are established according to the manufacturer's unified standards, follow a uniform model, and are authorized by the manufacturer to sell only a single brand of vehicles. Within the price range allowed by the manufacturer, they attract customers with the lowest possible prices, reflect the brand's related value, and maintain the brand's reputation. However, it is important to correctly understand that 4S stores should not be regarded as automobile manufacturers.

Can you turn right when the straight arrow is red?

No. For arrow traffic lights, you can only turn right when the right-turn arrow is green, and you must be in the right-turn lane to do so. If you are in the straight lane, you cannot turn right regardless of whether the straight arrow is red or green. Below is some relevant information about turning at straight arrow signals: 1. Motor vehicle signals and non-motor vehicle signals: At intersections without non-motor vehicle signals or pedestrian crossing signals, non-motor vehicles and pedestrians should follow the motor vehicle signals. When the light is red, right-turning vehicles may proceed if they do not hinder the passage of released vehicles or pedestrians. 2. Right-turn lane signal settings at intersections: When the signal is a circular light, if there is no 'No right turn on red' sign at the intersection, you may turn right; if there is such a sign, right turns are prohibited. Check if there is a 'No right turn' sign at the intersection—if there is, you cannot turn right; if not, you may turn right. When the arrow is red, if there is a right-turn arrow signal, you can determine whether a right turn is allowed based on the color of the right-turn arrow light.

How Does the Automotive Air Conditioning System Work?

Here is a detailed introduction to the working process of automotive air conditioning: 1. Compression process: The compressor draws in low-temperature, low-pressure refrigerant gas from the evaporator outlet and compresses it into high-temperature, high-pressure gas, which is then discharged from the compressor. 2. Heat dissipation process: The high-temperature, high-pressure superheated refrigerant gas enters the condenser, where it condenses into a liquid due to the reduction in pressure and temperature, releasing a significant amount of heat. 3. Throttling process: The refrigerant liquid, which is at a higher temperature and pressure, passes through the expansion device, causing its volume to increase and its pressure and temperature to drop sharply, exiting the expansion device as a mist (fine droplets). 4. Heat absorption process: The mist-like refrigerant liquid enters the evaporator. Since the boiling point of the refrigerant is much lower than the temperature inside the evaporator, the refrigerant liquid evaporates into a gas. During the evaporation process, it absorbs a large amount of surrounding heat, and the low-temperature, low-pressure refrigerant vapor then re-enters the compressor.
