What is the fuel tank capacity of an average car?

Generally, the fuel tank capacity of small cars ranges from 35 to 45 liters, while that of medium-sized cars ranges from 55 to 75 liters. A full tank typically allows a driving range of approximately 500 kilometers. The size of the fuel tank correlates with the vehicle's displacement: cars with higher fuel consumption have larger tanks, while those with lower consumption have smaller ones. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the tank capacity specified by car manufacturers measures from the bottom of the tank to the safety level, leaving some space between the safety level and the tank opening. This space ensures that the fuel can expand when temperatures rise without overflowing from the tank. If fuel is added up to the tank opening during refueling, the actual amount of fuel may exceed the calibrated tank capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the dashboard, which is marked with 'E' and 'F'. When the needle approaches 'E', it indicates low fuel, while nearing 'F' means the tank is nearly full.

What to Do If There's a Car in Front During Straight-Line Driving in Subject Three Exam?

Upon hearing the "straight-line driving" voice command, if there is a car blocking the exam vehicle ahead, the examinee should prioritize following the examiner's instructions. Typically, in such situations, the examiner will require the examinee to maintain an appropriate distance from the car in front and complete the straight-line driving operation in the current lane. Additional details are as follows: 1. Straight-line driving, as the name suggests, means keeping the driving path in a straight line. After hearing the voice prompt "Please maintain straight-line driving," the examinee should look straight ahead, control the steering wheel with both hands, and keep the vehicle driving straight. 2. To keep the vehicle driving straight, one must learn to focus on a distant point on the road, making it less likely for the vehicle to deviate.

What documents are required for new vehicle inspection?

New vehicle inspection requires the owner's ID card, vehicle registration certificate, compulsory traffic insurance policy, and vehicle and vessel tax payment or tax exemption certificate. The inspection process for new vehicles is relatively simple, mainly focusing on checking the vehicle's exterior, exhaust emission standards, engine specifications, etc. Since the vehicle has not been used before, most parts are in brand-new condition, making it easy to pass the inspection. During the annual vehicle inspection, the main checks include the vehicle's exterior, frame number, engine number, triangular warning sign, fire extinguisher, exhaust emissions, lights, brakes, etc. If any item fails the inspection, the vehicle must undergo repairs and be re-inspected. Precautions for annual vehicle inspection: 1. The insurance policy must not be expired; 2. The vehicle must not be modified; 3. All required materials for inspection must be complete; 4. Safety items such as the in-car fire extinguisher must be properly equipped.

How Should Automotive Clear Coat Be Sprayed?

The most basic requirement for automotive spray painting is maintaining stable air pressure, with the recommended pressure being 6-8 bars! Then adjust the spray gun fan size according to your preference. When spraying, each pass should overlap the previous one by 1/3, ensuring even coverage. First and foremost, when painting a car, do not add too much thinner; it's better to use a little less. When applying the first coat of paint, it's crucial to estimate the amount correctly. If it's insufficient, mix black or white paint with the original paint as a base, then cover it with the original paint. In cold weather, make sure the first coat is completely dry before applying the second coat. If the gloss is too high, pay special attention to the spray gun distance and speed for the second coat. The first clear coat should be applied fully to achieve gloss, with a slightly longer flash-off time in between. This initial coat primarily serves to smooth the paint surface, setting the stage for the second clear coat. If the second, slightly thicker clear coat is applied evenly, it can achieve the best leveling effect.
