What Happens When a Vehicle's Exhaust Pipe is Blocked?

If the exhaust cannot escape, fresh air cannot enter either, the spark plug fails to ignite, and the vehicle cannot start. Here are the troubleshooting methods for exhaust pipe faults: 1. First, start the diesel engine to a speed of about 700r/min, then perform a fuel cut-off check cylinder by cylinder. When disconnecting the high-pressure fuel pipe of the second cylinder, observe that the exhaust smoke changes from the original gray-white smoke to a large amount of white smoke, indicating an internal fault in the second cylinder. 2. Remove the injector of the second cylinder and check its injection pressure and atomization quality. It is found that the injector nozzle assembly is leaking fuel. After replacing the assembly, reassemble and restart the diesel engine. Observe the exhaust smoke and find that it changes from the original gray smoke to a large amount of white smoke, indicating that water has entered the combustion chamber. The cylinder head, cylinder gasket, and cylinder liner should be disassembled for inspection. 3. After stopping the engine, when disassembling the cylinder head, it is found that four nuts on the first and second cylinders' cylinder head become loose when tightened with a torque of 100N·m. This situation is caused by the cylinder gasket not being properly compressed, leading to water entering the combustion chamber. 4. After re-tightening with a torque of 280N·m as required, start the diesel engine for 5 minutes, and the white smoke from the exhaust pipe disappears, indicating the fault has been resolved.

How to Use the Auto Hold Function?

To use the auto hold function, press the auto hold button on the vehicle to activate it. Once activated, there is no need to press the brake pedal or pull the handbrake; the system will automatically brake the vehicle. The system will release automatically when the accelerator pedal is pressed. Here is an introduction to the auto hold function: 1. Currently, there are two types of electronic handbrake switches on the market. One is a standard button type: pressing it once activates the electronic handbrake, and pressing it again deactivates it. The other is a toggle-type button, similar to a window switch: pulling it up activates the handbrake, and pressing it down deactivates it. 2. Some models label the button directly as "AUTOHOLD," while others use a design with two semicircles enclosing an "A" inside a circle. Although the designs vary, the functions of these buttons are the same. The functions of auto hold are as follows: 1. In situations requiring short stops, such as at traffic lights, the system will automatically brake the wheels after the vehicle comes to a stop to prevent rolling. 2. During uphill starts, the system will automatically brake to prevent rolling backward. Once the vehicle starts moving, the system will release the wheels automatically for forward movement. 3. When parking and locking the vehicle, there is no need to pull the handbrake, as the system will automatically brake the wheels (though this feature is limited to certain models).

Will the vehicle certificate be confiscated during license plate registration?

When completing the registration process, it is mandatory to submit the motor vehicle certificate. After registration, the motor vehicle certificate is stored in the vehicle's file at the vehicle management office. The registration process for motor vehicles is as follows: 1. After purchasing a motor vehicle, you must first pay for compulsory traffic insurance, which can be done directly at the 4S dealership or through an insurance company. The 4S dealership should also provide a temporary license plate. 2. With the compulsory insurance policy, purchase invoice, and motor vehicle certificate, go to the tax bureau to pay the vehicle purchase tax. 3. Take the relevant documents to the service hall to fill out the vehicle registration application form and pay the registration fee. Check at the designated counter whether the vehicle is exempt from inspection. If it is, you can directly print the inspection exemption certificate. Then proceed to the outdoor area for photo-taking and exterior inspection, ensuring you have a fire extinguisher and warning triangle ready. If you have the inspection exemption certificate, no on-site inspection is required. If the vehicle is not exempt from inspection, an on-site inspection is necessary. 4. After the exterior or on-site inspection, return to the service hall to collect the motor vehicle registration certificate and vehicle license at the designated counter. At the same time, you will receive the annual inspection sticker, environmental compliance sticker, vehicle license plate, and anti-theft screws.

How Early Should I Schedule Subject 4?

Subject 4 can be scheduled after passing Subject 3. The Subject 4 theory test, also known as the driver's theory test, is part of the assessment for obtaining a motor vehicle driver's license. After the implementation of the Ministry of Public Security's Order No. 123, Subject 3 was divided into two parts: the road test and the safe and civilized driving test, commonly referred to as "Subject 4," which assesses "driving ethics." Since this test is conducted after Subject 3, it is commonly called the Subject 4 test. Subject 4 Test Content: 1. Depending on the type of driver's license being tested, 50 questions are randomly selected from the corresponding Subject 4 question bank at a set ratio. For car licenses, questions are drawn from a pool of 1,240, while for large vehicle licenses, questions are drawn from 1,235. Each question is worth 2 points. 2. The test duration is 45 minutes. If 12 points (6 questions) are answered incorrectly during the test, the session will be terminated. 3. The test includes true/false questions (Questions 1-22), single-choice questions (Questions 23-45), and multiple-choice questions (Questions 46-50). 4. The test questions include image-based questions, scenario recognition questions, and text-based questions.

What Are the Reasons for a Sudden Increase in Motorcycle Fuel Consumption?

Possible reasons for a sudden increase in motorcycle fuel consumption are as follows: 1. If you notice a significant reduction in the coasting distance of your motorcycle during travel, weakened coasting effect on downhill roads, or increased difficulty in pushing the bike when it's unloaded, you should check whether the tire pressure meets the standard. Insufficient tire inflation can lead to a notable increase in fuel consumption. 2. If you observe front or rear wheel wobbling while riding, immediately check the tire pressure and wear level, and whether the wheels and suspension arms are loose. Severe tire wear or insufficient pressure can frequently cause wobbling, especially on roads with longitudinal grooves. 3. If you hear abnormal noises from the wheel axle during riding or startup, promptly inspect the bearings and brake system for faults. If the wheels do not rotate normally or the brake pads cause the wheel rims to overheat, it will affect speed and stability, leading to increased fuel consumption. 4. Slipping clutch shoes in scooters can impact maximum speed and uphill torque, and may also cause overheating of nearby components. If the engine RPM rises quickly during rapid acceleration but the speed increases slowly, it can be determined that the clutch is slipping. 5. After a motorcycle has traveled 20,000 kilometers, the piston rings typically wear out, leading to air leakage and insufficient cylinder pressure. Cold starts may feel easier, but ignition becomes difficult. Poor cylinder sealing will result in a noticeable increase in fuel consumption.
