The working principle of a plug-in hybrid is that during driving, the plug-in hybrid vehicle charges the power battery through energy recovery. However, due to the larger capacity of the power battery in plug-in hybrid models, when the vehicle is driven by the engine at a relatively stable speed, a portion of the engine's torque is used to drive the motor for power generation, thereby charging the power battery. Advantages and disadvantages of plug-in hybrid electric vehicles: 1. Compared with non-plug-in hybrid vehicles: Plug-in hybrid vehicles have a larger battery capacity, which can support longer driving distances. If every trip is short-distance and there are good charging conditions, plug-in hybrid vehicles can be used without refueling, functioning as pure electric vehicles, thus possessing the advantages of pure electric vehicles. 2. Compared with pure electric vehicles: Plug-in hybrid vehicles have a much smaller battery capacity, but they are equipped with traditional internal combustion engines, transmissions, drivetrains, fuel lines, and fuel tanks. Therefore, when charging is not possible, as long as there are gas stations, they can continue to drive without being limited by charging conditions.

External or Internal Tire Pressure Monitoring: Which is Better?

Tire pressure monitoring systems, whether internal or external, each have their own advantages and disadvantages. The choice can be made based on the specific needs of your vehicle. Advantages and disadvantages of internal tire pressure monitoring devices: Advantages: Installed inside the tire, they replace the original valve with a sensor-equipped valve, with minimal external protrusion. Once installed, they are virtually maintenance-free (lasting over 5 years without issues). Disadvantages: Installation is complex and requires wheel balancing. Advantages and disadvantages of external tire pressure monitoring devices: Advantages: Easy installation. No need to replace the valve, no wheel balancing required, and often no need for inflation or deflation. The owner may only need to screw the sensor onto the valve. Disadvantages: Not suitable for SUVs with higher tire pressure. Inflation and deflation require removing and reinstalling the sensor. External sensors are prone to damage from foreign objects. How tire pressure monitoring works: Pressure sensors installed inside the tire measure the tire's air pressure, and a wireless transmitter sends this information from inside the tire to a central receiver module. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and misalignment, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends the tire cords, reducing elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, the tire is more likely to be punctured, leading to internal cracks, blowouts, or even tire bursts.

How Many Chances Are There for the First Attempt at Subject One Exam?

The "Regulations on the Application and Use of Motor Vehicle Driving Licenses" clearly stipulates that there are two attempts for the Subject One exam on the same day. If the first attempt is failed, a free retake is allowed for the second attempt. If the second attempt is also failed, the Subject One exam for this session is terminated, and the candidate can only schedule another exam after ten days. Subject One, also known as the Subject One theory exam or driver theory exam, is part of the motor vehicle driving license assessment. The exam content includes driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The exam is conducted on a computer with a time limit of 45 minutes. To pass the Subject One exam, a score of 90 or above is required. The exam consists of 100 questions, including single-choice and true/false questions, with each question worth 1 point (total score: 100). If 11 questions are answered incorrectly during the exam, the system will automatically submit the exam and end the session. Subject One exam content includes: driving license and motor vehicle management regulations; road traffic conditions and rules; road traffic safety violations and penalties; road traffic accident handling regulations; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject One exam precautions: Candidates should dress appropriately (no slippers allowed) and are prohibited from bringing electronic devices or bags into the exam hall. They must bring their ID card and queue to enter the waiting area. Observe the precautions and procedures displayed on the screen, and store personal belongings in lockers before entering the exam hall. After identity verification, candidates will be assigned seats and begin the exam. Ensure the camera is properly aligned and follow exam discipline. If the first attempt is failed, a retake is allowed on the same day. If the retake is also failed, the candidate must pay to reschedule. After the exam, queue to collect the score report and sign it—failure to sign renders the result invalid. There is no limit to the number of times Subject One can be scheduled. Each subject exam allows one retake if the first attempt is failed. If the retake is also failed or skipped, the exam session is terminated, and the applicant must reschedule. In contrast, Subject Two and Subject Three only allow five exam attempts, with rescheduling permitted after ten days. If the Subject Three safety and civilized driving knowledge exam is failed, the passed road driving skills exam results remain valid. The driving test consists of three subjects: Subject One, Subject Two, and Subject Three. Subject One refers to the road traffic safety laws, regulations, and related knowledge exam; Subject Two refers to the field driving skills exam; Subject Three is divided into two parts: road driving skills and safety and civilized driving knowledge exams. The safety and civilized driving knowledge exam is conducted after Subject Three, so it is commonly referred to as Subject Four. However, the official term (as per the Ministry of Public Security Order No. 123) does not include "Subject Four."

What is the identification of emergency phones on highways?

Highway emergency phones are marked with a black telephone inside a dark green square frame. Below is a partial introduction to emergency phones: 1. On highways, emergency phones are installed at regular intervals for requesting towing in case of vehicle breakdown or reporting accidents. It is a dedicated line that only connects to the highway traffic command center. 2. No dialing is required for use. There is a button on the phone panel - simply press it with your index finger, release after a moment, and you can communicate with the traffic command center. Before speaking, confirm your location's kilometer marker, time, general vehicle malfunction details, or accident scale and casualties to facilitate coordinated arrangements by relevant departments.
