How to Check the Average Fuel Consumption of a Car?

If the car has a multifunction steering wheel, you can check it by pressing the buttons. If it's not a multifunction steering wheel, you can refer to the vehicle's manual. More extended information is as follows: 1. Fuel consumption per 100 kilometers: This refers to the fuel consumption of a vehicle traveling a certain speed on the road for 100 kilometers. It is a theoretical indicator of the vehicle. 2. Data on fuel consumption per 100 kilometers: The fuel consumption per 100 kilometers is a value measured by the manufacturer in an objective environment using a dynamometer installed on the vehicle's chassis, converted into speed parameters, and then calculated at a specified speed to determine the theoretical experimental fuel consumption data per 100 kilometers for the model. Since most vehicles approach their economical speed at 90 km/h, the theoretical fuel consumption figures publicly announced by most manufacturers are usually the fuel consumption per 100 kilometers at 90 km/h. (Displacement is determined by analyzing the carbon content in the exhaust gas using an exhaust analyzer and the carbon balance method).

What is the difference between a driver's license and a vehicle license?

The difference between a driver's license and a vehicle license lies in their definitions and acquisition methods. Different definitions: A driver's license, also known as a driving permit, is a document issued after passing the driving test, which authorizes the holder to operate a vehicle on public roads. A vehicle license serves as an identification document, containing various information such as the license plate number, owner's name, engine number, seating capacity, etc. It is unique to a specific vehicle, with only one set of engine number, chassis number, and license plate number assigned to each car. Different acquisition methods: To obtain a driver's license, one must enroll in a driving school and pass the required tests. A vehicle license is obtained after purchasing a car by presenting the vehicle's factory certificate, paying the vehicle purchase tax, and purchasing insurance, after which the vehicle license can be issued.

What is the mechanism behind engine shaking faults?

Engine shaking faults occur due to the following mechanisms: 1. Poor combustion state. 2. Engine knocking, poor fuel quality. 3. Dirty engine cylinder interiors, with accumulated carbon deposits, etc. Below are the methods to address engine shaking: 1. Replace the air filter. The air filter is designed to protect the engine and reduce wear, typically requiring replacement around 10,000 kilometers. 2. Replace the spark plugs. After 30,000 to 40,000 kilometers of use, the ignition efficiency of spark plugs significantly decreases, affecting ignition. 3. Adjust the water temperature. High engine water temperature can cause early ignition timing, changes in the air-fuel mixture ratio, thinning of engine oil viscosity, and reduced lubrication performance. 4. Clean the fuel injectors. Gum in gasoline can clog the injector nozzles, leading to inconsistent fuel injection among injectors and uneven cylinder operation. 5. Clean carbon deposits, oil sludge, the throttle body, and the idle speed valve. Over time, the intake ports can become clogged with carbon deposits and oil sludge, obstructing airflow and affecting idle stability.

Can Vehicle Location Be Queried Using License Plate Number?

Knowing the license plate number alone is insufficient to locate a vehicle. License plates serve as unique identifiers for vehicles, allowing identification of the province, city, or county of registration. Vehicle management offices can trace the owner through the plate number, but cannot pinpoint the vehicle's location. Only traffic police departments can track a vehicle's movements via the Tianwang surveillance system. Additional details are as follows: 1. Ordinary individuals cannot access owner information online using a plate number: This constitutes privacy protection, with no public access rights. Traffic police and law enforcement may retrieve owner details through official channels. 2. Owner information is confidential: Not publicly available to all parties. 3. For legitimate inquiries, individuals must present valid credentials to insurance companies: By submitting the target vehicle's plate number through proper channels, one may request owner identification. However, due to stringent privacy protections, the required procedures are complex. Insurance companies will not assist with inquiries motivated by malicious intent such as vendettas or retaliation.

How Long to Charge a Dead Battery at Idle Speed?

When a car is idling, the generator runs at a low speed, resulting in a small charging current. It may take more than 6 hours of high-speed driving to fully charge the battery. Here is more information about idling in place: 1. Reason: Prolonged idling in place can affect the car's engine, leading to increased carbon deposits inside the engine. 2. Correct Practice: After starting the engine, you can drive in gear for a while, which is beneficial for the car's engine, transmission, battery, and tires. 3. Proper Warm-Up Method: Drive at low speed. After idling in place for half a minute to 1 minute, when the engine speed stabilizes, you can shift into gear and drive, keeping the speed below 2000 RPM, shifting gears gently and accelerating steadily. This is the most standard and correct warm-up method, which is energy-saving, environmentally friendly, and reduces carbon deposits.

Will Missing the Subject 4 Exam Affect the Next Appointment?

Missing the Subject 4 exam will not affect the next appointment. Here is some relevant information about Subject 4: 1. Main exam content: Requirements for safe and civilized driving operations, knowledge of safe driving under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident handling knowledge. 2. Retake instructions: If you fail Subject 4, you do not need to retake the previously passed subjects (Subject 1, Subject 2, Subject 3). You can schedule a retake on your own without paying any retake fees. There are no appointment restrictions for the safe and civilized driving theory exam, but the driving skill test permit is valid for three years. If the applicant does not complete the exam within the validity period, the passed subject scores will become invalid.
