What are the Internal and External Circulation in a Car?

Internal circulation in a car refers to the process where the air inside the vehicle is heated or cooled and then recirculated back into the cabin. External circulation, on the other hand, involves drawing in outside air, heating or cooling it, and then introducing it into the cabin, facilitating gas exchange between the interior and exterior of the vehicle. Uses of internal and external circulation: 1. In cold weather, after starting the car and waiting for the engine temperature to reach normal levels, activating internal circulation can quickly raise the cabin temperature; 2. During high-speed driving, external circulation can be turned on as needed to maintain cabin temperature while ensuring fresh air supply. Advantages and disadvantages of internal and external circulation: The advantage of internal circulation is the rapid cooling or heating effect of the air conditioning system, while the drawback is that prolonged use may lead to poor air quality inside the cabin. The advantage of external circulation is maintaining clean air inside the cabin, but the downside is slightly less effective cooling or heating due to the influx of outside cold or hot air.

What is a Half Shaft?

Half shaft, also known as drive shaft, refers to the shaft that transmits torque between the gearbox reducer and the drive wheel. It has a universal joint at each end, connecting to the splines on the universal joint, the reducer gears, and the inner ring of the hub bearing. The function of the half shaft is to transmit power between the differential and the drive wheels. Modern vehicles commonly use two types of half shafts based on their support configurations: full-floating and semi-floating. The full-floating half shaft only transmits torque and does not bear any reaction forces or bending moments. When paired with independent suspension, it helps improve vehicle comfort, making it widely used in various types of vehicles. The full-floating half shaft is easy to install and remove; during maintenance, simply unscrew the fixing bolts to extract the half shaft, while the wheel and axle housing can still support the vehicle, facilitating vehicle maintenance. The semi-floating half shaft transmits torque while bearing all reaction forces and bending moments. Its support structure is simple and mainly suitable for pickup trucks and SUVs with lower comfort requirements. However, this type of half shaft support is troublesome to remove, and if the half shaft breaks during driving, it may cause the wheel to detach, posing a safety hazard.

What Are the Gears in an Automatic Car?

Here is an introduction to the gears of an automatic transmission car: 1. All gears: The gears of an automatic transmission include P, R, N, D, 2 or S, and L or 1. 2. Parking gear: P stands for Parking gear, also known as the parking position. 3. Other gears: R is for Reverse, N is for Neutral, and D is for Drive, also known as the driving position. 4. Sport mode: S or 2 represents Sport mode. 5. Low gear: L or 1 is for Low gear, also known as first gear. Below is additional information on gear selection when an automatic car is stopped at a red light: 1. Less than 20 seconds: If waiting for less than 20 seconds, use D gear along with the foot brake. 2. More than 30 seconds: If waiting for more than 30 seconds in traffic, use N gear along with the handbrake. 3. More than 2 minutes: If waiting for more than 2 minutes, use N gear along with the handbrake and finally turn off the engine.

How Long Does It Take to Get a Driver's License After Passing Subject Four?

After completing Subject Four, the license is issued on the spot, usually within about 2 hours. Subject Four, also known as the Subject Four theory test or driver's theory 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 knowledge on handling traffic accidents. The Subject Four test consists of 50 questions, primarily in the form of case studies, images, and animations, with a full score of 100 and a passing score of 90. After the implementation of the Ministry of Public Security's Order No. 123, the Subject Three test was divided into two parts: in addition to the road test, a safety and civilization knowledge test was added, commonly referred to as 'Subject Four,' which assesses 'driving ethics.' Because this test is conducted after Subject Three, it is commonly referred to as the Subject Four test. Officially, there is no Subject Four. Before the test, students can study traffic regulations through driver's mock test software on mobile or computer devices.

What is the difference between China United Petroleum and PetroChina?

The differences between China United Petroleum and PetroChina are as follows: They have different predecessors: China United Petroleum Co., Ltd. is a petroleum foreign trade company jointly established by China National Petroleum Corporation and China National Chemicals Import & Export Corporation; while Sinopec is a super-large petroleum and petrochemical enterprise group reorganized and established by the state in July 1998 on the basis of the former China Petrochemical Corporation. It is a state-owned company solely funded by the state, an authorized investment institution, and a state-controlled company. They operate in different regions: They are located in different regions, with China United Petroleum having more oil fields, while Sinopec has more refineries. "PetroChina" and "Sinopec" are basically divided between the "north" and the "south". That is, the north is the territory of China United Petroleum, and the south is the territory of Sinopec. However, in recent years, this situation has seen some breakthroughs, just like China Netcom and China Telecom started to expand southward and northward respectively.
