What is the total number of cars in China?

As of September 2018, the total number of motor vehicles in China reached 322 million, including 235 million cars. The following is relevant information about car ownership: Definition: Car ownership (car-parc) refers to the number of vehicles in a region, usually referring to vehicles registered locally. However, car ownership is different from motor vehicle ownership, as the latter includes motorcycles, agricultural vehicles, etc. Problems caused by the increase in car ownership: Although China's car ownership per thousand people is still less than half of the world average, the traffic congestion and air pollution caused by the rapid increase in the number of cars have reached a very serious level. Almost all major cities suffer from severe traffic congestion, and before National Day, Beijing repeatedly experienced unprecedented traffic jams. Air pollution caused by vehicle exhaust emissions has become the main source of pollution in many large cities.

What is the difference between service brake and parking brake?

Service brake and parking brake have the following differences: Working principle: The parking brake refers to the handbrake, while emergency braking is mainly distinguished from anticipatory braking, which means taking immediate braking measures when an emergency is detected to stop the vehicle in the shortest possible time. Engine braking refers to using the engine's drag force to implement braking, such as when going downhill for a long distance. If the brakes are applied for too long, the brake pads may burn out. In such cases, you can shift to a lower gear and coast at idle speed, using the engine's drag force to control the vehicle's speed. Usage scenarios: The brake is the braking system. Brakes are divided into service brakes (foot brake) and parking brakes (handbrake). During driving, the service brake (foot brake) is generally used to slow down or stop the vehicle while moving forward, not just to keep the car stationary. The parking brake is used only when the service brake fails. When the vehicle comes to a complete stop, the parking brake (handbrake) should be applied to prevent the vehicle from sliding forward or rolling backward.

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.
