How many exam attempts are allowed per subject one booking?

Each subject exam allows two attempts. If you fail twice, you need to reschedule the exam. Subject one exam content: Basic knowledge of motor vehicles; laws, regulations, and road traffic signals; fundamental knowledge of safe and civilized driving; basic operational knowledge of motor vehicle driving. Subject one exam process: Follow the staff's arrangements and collect your driving school file in an orderly manner in the waiting room; Bring your ID card and undergo inspection by the supervising officer; Mobile phones must be turned off when entering the exam area; Do not make loud noises in the exam area; Legal and regulatory materials are not allowed in the exam room (or must be placed in your bag); After the exam, retain your ID card and submit your file at the "submission window" in front of the exam room. Students who pass the exam will sign at the exit under the guidance of the staff and then leave the exam room; Students who fail the exam can leave the exam room and wait for the driving school staff to notify them of the retake time.

What Are the Reasons for a Car Not Moving?

Reasons for a car not moving include: 1. Battery depletion: The battery voltage is below the rated value, preventing the starter from operating normally; 2. Fuel flow obstruction: Long-term dirt accumulation in the fuel lines, and at lower temperatures, water mixing with debris blocks the fuel lines, resulting in no oil pressure in the engine's fuel supply pipe, causing failure to start; 3. Poor ignition system performance: Insufficient ignition energy, excessive fuel accumulation in the cylinder, exceeding the ignition limit concentration, making normal operation impossible. Solutions for a car not moving are: 1. Charge the battery; 2. Place the car in a warm environment or clean the fuel lines; 3. Check the ignition system to eliminate the cause of low ignition energy.

How can beginners determine the position of their car tires while driving?

Beginners can determine the position of their car tires through the following methods: Using the nodes of the vehicle's wipers to determine the position of the wheels: However, this method is not suitable for all car models. The sizes of wipers vary among different models, and the driver's sitting posture also differs, which may lead to slight inaccuracies when determining the position of the wheels. Using the vehicle's steering wheel to determine the position of the left-side wheels: Since the steering wheel in China is on the left, it is relatively easier to determine the position of the left front wheel. The leftmost edge of the steering wheel, when extended forward in a straight line, indicates the position of the left-side wheels. If this line coincides with the road markings, it means the car is driving on the line. Using the emergency hazard light button switch in the vehicle: Nowadays, the emergency hazard light switches in many vehicles are designed in the center of the dashboard. While driving, the extension line of the hazard light switch's position can be used to determine the position of the right-side wheels.

Is Valve Noise Related to Engine Oil?

Valve noise is related to engine oil. The following are the relevant reasons: Insufficient Engine Oil: When the engine oil level is insufficient, the oil level drops to a certain extent, allowing air to enter the hydraulic lifters through the oil passages, creating gaps and causing valve noise. Sludge in Oil Passages: During engine operation, engine oil circulates through the hydraulic lifters. When sludge forms in the engine, it can clog the oil passages, causing the automatic gap adjustment function of the hydraulic lifters to fail, resulting in valve noise. Incorrect Oil Viscosity Selection: When the engine is severely worn, using oil with a lower viscosity (e.g., 20 or 30 viscosity oil) can also cause valve noise. In such cases, switching to a higher viscosity oil (e.g., 40 or 50 viscosity oil) can eliminate the valve noise.

What is the difference between MT and CVT?

MT and CVT both refer to types of automotive transmissions, with the difference being that MT stands for manual transmission, while CVT is an automatic transmission. Below are the relevant introductions about MT and CVT: MT: MT requires manually shifting the gear lever (commonly known as the gear stick) to change the gear engagement position inside the transmission, altering the gear ratio to shift the car's speed. Most manual transmissions in passenger cars are four or five-speed gear transmissions, typically equipped with synchronizers for easier shifting and reduced noise. When operating a manual transmission, the clutch must be depressed to move the gear lever. CVT: The gear ratio in a CVT is not a series of discrete points but a continuous range of values, for example, it can vary from 3.455 to 0.85. The structure of a CVT is simpler than that of a traditional transmission, with a smaller size. It does not have the numerous gear pairs of a manual transmission nor the complex planetary gear sets of an automatic transmission. Instead, it primarily relies on the primary and secondary pulleys and a metal belt to achieve stepless variation of the gear ratio.
