How many meters does the straight-line driving in Subject 3 end?

There is no fixed distance for straight-line driving in Subject 3, but it is approximately around 100 meters. The main challenge of this test item is to keep the vehicle moving in a straight line. Some people think that driving at a slower speed can ensure straight-line driving. However, it is important to note that there is also a speed requirement for straight-line driving, and the vehicle must reach the specified speed to pass. Below is relevant information: Straight-line driving test rules: If the direction control is unstable and the vehicle cannot maintain straight-line driving, the test is directly failed; if the specified speed is not maintained, 10 points are deducted; if the vehicle deviates more than 30 cm during driving, the test is directly failed. Subject 3 test content: preparation before starting, light simulation test, starting, straight-line driving, gear shifting operation, lane changing, pulling over, driving straight through intersections, left turns at intersections, right turns at intersections, passing through pedestrian crossings, passing through school zones, passing through bus stops, meeting vehicles, overtaking, making U-turns, and night driving.

Is the Temporary License Plate Number the Same as the Official License Plate Number?

Temporary license plates and official license plate numbers are different. Temporary license plates are randomly assigned numbers for temporary use, with a validity period of three months. Official license plates require selecting a number at the local vehicle management office for registration. Below are the conditions for applying for a temporary license plate: 1. When driving a vehicle from the place of purchase to the place of use, a temporary license plate must be applied for at the vehicle management office in the place of purchase. 2. When transferring vehicle registration and after paying for the official license plate, a temporary license plate must be applied for at the local vehicle management office to drive back to the original location. 3. For a new vehicle in the local area that has not yet obtained an official license plate and needs to be driven to another location for modifications, a temporary license plate must be applied for locally. After modifications are completed, a temporary license plate must be applied for at the local office to drive back to the original area. 4. When purchasing a vehicle locally and needing to drive it to another location, a temporary license plate must be applied for locally to drive to the other location; the same applies vice versa. 5. Vehicles that have not yet been permanently registered and require temporary trial use.

What are the conditions for an engine to start?

Engine starting requires three basic conditions: fuel, spark, and cylinder pressure. The engine converts other forms of energy into mechanical energy. The function of an automobile engine: It serves as the power-generating device for a car, acting as the heart of the vehicle, determining its power, fuel efficiency, stability, and environmental performance. Depending on the power source, automobile engines can be classified into diesel engines, gasoline engines, electric vehicle motors, and hybrid systems. Common gasoline and diesel engines are both reciprocating piston internal combustion engines that convert the chemical energy of fuel into the mechanical energy of piston movement to generate power. Engine maintenance methods: Use high-quality engine oil, use qualified coolant, regularly clean radiator scale, periodically remove carbon deposits from the car, replace the three filters on time, and maintain reasonable engine speed.

What is the method for changing brake fluid?

Open the car hood, locate the brake fluid reservoir, and remove the reservoir cap to inspect the quality of the brake fluid. Use a syringe to extract all the old brake fluid from the reservoir, then refill it with new brake fluid. During the extraction process, avoid splashing the fluid on yourself to prevent corrosion from the brake fluid. Other methods for changing brake fluid are as follows: 1. Locate the two brake lines on the master cylinder in the engine compartment. Use a line wrench to loosen them until brake fluid begins to flow out. Once the reservoir is empty, tighten the lines. 2. Refill the brake fluid reservoir, lift the vehicle, and have one person sit inside to pump the brake pedal several times and then hold it down. Another person underneath the vehicle should use a wrench to loosen the bleeder screw on the brake caliper, allowing brake fluid to drain. Follow the farthest-to-closest principle: bleed the left rear, right rear, right front, and left front calipers in sequence. 3. Lower the vehicle, refill the reservoir, lift it again, and repeat the bleeding process for all four calipers in the same order. Once completed, tighten all bleeder screws and check for leaks to ensure a complete brake fluid replacement.

What Causes a Modified One-Button Start to Fail to Ignite?

The reasons why a modified one-button start fails to ignite are as follows: Steering Wheel Lock: The steering wheel lock is a simple anti-theft feature. When the car is turned off, if the steering wheel is rotated a certain angle from its centered position in one direction, it will make a "click" sound and lock. In this state, the one-button start function will not work. The solution is to turn the steering wheel left and right while pressing the engine start button to release the tension and unlock the steering wheel. Gear Not in Park: This is another important safety logic set by manufacturers for vehicle owners. Consider this: if the car could start directly while in reverse or drive gear, the vehicle would lurch forward or backward during ignition. Therefore, manufacturers have implemented this setting for safety reasons.

What are the symptoms of chassis abnormal noise?

The symptoms of chassis abnormal noise are as follows: Universal joint failure of the drive shaft: It may be caused by a broken dust cover or oil leakage that was not repaired in time. The solution is to replace the new universal joint of the drive shaft. Interference between components: It may be caused by collision or the installation of other equipment, which causes mutual influence between two components. The solution is to repair or replace the relevant components to eliminate interference. Loose bolts or nuts: It may be caused by long-term driving on roads with poor conditions, natural loosening of bolts, improper disassembly and installation that damages the bolts, insufficient tightening torque, or incorrect bolt specifications. The solution is to tighten or replace the bolts and nuts.
