Reasons for a motorcycle stalling automatically: 1. Fuel supply failure. The solution is to check if there is fuel in the carburetor. If there is no fuel, it indicates a blockage in the fuel line from the fuel tank to the carburetor, which should be cleaned and unclogged. 2. Engine overheating. The solution is to check if there is lubricating oil in the crankcase. If the lubricating oil is insufficient or absent, inspect the oil pan or drain plug for leaks. After identifying and fixing the issue, refill with the specified amount of lubricating oil. 3. Electrical circuit failure. Sudden stalling caused by an electrical circuit interruption will not show any abnormal signs in the engine beforehand. Causes of sudden electrical interruption include loose or disconnected connectors, broken wires, or short circuits. The solution is to check all connectors, clean off any oil stains, increase the clamping force of the connector tabs, and enhance contact strength to ensure stable connectivity.

What is the proper air pressure for painting?

Painting normally requires an air pressure of 0.3~0.6Mpa. Painting: Paint is a type of synthetic lacquer made from nitrocellulose, resins, pigments, solvents, etc. It is typically applied evenly onto surfaces using a spray gun, offering water resistance, oil resistance, and quick drying. It is used for painting cars, airplanes, wooden objects, leather, etc. This substance is toxic and can have certain effects on the body. The toxicity varies depending on the brand due to differences in ingredient composition. Special care should be taken during use to avoid inhalation and skin contact. Air pressure spraying method: Air pressure spraying is a type of spraying technique. It involves atomizing the paint with compressed air and spraying it onto the surface of the substrate (plastic or other materials) through a nozzle. This method is suitable for coating porous materials and substrates that should not be saturated. Air pressure spraying is further divided into suction-type spraying and pressurized air spraying.

Will a car lose acceleration power when it gets too hot?

Yes, a car that has become overheated can experience a loss in acceleration power. Here are the relevant explanations: 1. Ignition system failure: Aging ignition coils or spark plugs that haven't been replaced for a long time can lead to insufficient ignition energy and poor combustion. This results in weak engine acceleration and the illumination of the engine fault light; low pressure caused by fuel system malfunctions can also contribute. 2. Excessive engine carbon buildup: This can impair fuel atomization, leading to poor combustion of the air-fuel mixture, excessive exhaust emissions, and weakened engine acceleration. 3. Engine system malfunctions: These can cause the engine to enter an emergency operating mode, thereby limiting power output and resulting in poor acceleration. Examples include failures in engine sensors such as oxygen sensors, air flow meters, crankshaft position sensors, knock sensors, etc. Signal faults from these sensors can trigger the engine's emergency operation mode, slowing down acceleration.

How to sense the position of the wheels?

Use the steering wheel as a reference for observation. Here are the specific methods to sense the position of the wheels: 1. Sensing the left wheel position: When driving on a road with marked lines, use the steering wheel as a reference. Observe the leftmost edge of the steering wheel, then look straight ahead. As the edge line extends forward and aligns with the road's edge line, a perpendicular tangent line to the steering wheel's edge will pass exactly over the left tire. This helps determine the correct position of the wheel. 2. Sensing the right wheel position: Similarly, using the steering wheel as a reference, when you see the rightmost edge of the steering wheel, look outward an additional 10 centimeters. This creates a line extending to the right front, and the extension of this line indicates the correct position of the right front wheel. Of course, it's undeniable that different sitting postures may result in slight variations.

Why Can't I Find Information After Accumulating 12 Points?

If you can't find information after accumulating 12 points, it's because the violation information has not yet been uploaded to the computer network. Attend Study Session: Motor vehicle drivers must, within fifteen days, attend a seven-day study session on road traffic safety laws, regulations, and related knowledge at the traffic management department of the public security organ where the driver's license was issued or where the violation occurred. Take the Exam: After attending the study session, the vehicle management office must administer a road traffic safety laws, regulations, and related knowledge exam within twenty days. Pass the Exam to Clear Points: Those who pass the exam will have their points cleared and their driver's license returned. Those who fail will continue to attend study sessions and retake the exam. Those who refuse to attend the study session or take the exam will have their driver's license suspended by the traffic management department of the public security organ.

What is the reason for pressing the left line at the second curve during serpentine driving?

Pressing the left line at the second curve during serpentine driving is due to improper speed control, failure to identify the correct reference point, or turning the steering wheel too quickly and abruptly. S-curve entrance: When entering from the left, keep the vehicle as close to the right line as possible before turning the steering wheel to the left; when entering from the right, keep the vehicle as close to the left line as possible before turning the steering wheel to the right. During the movement, the front of the vehicle should follow the edge line. When turning left, the front of the vehicle should follow the right line; when turning right, the front of the vehicle should follow the left line. S-curve exit: When exiting to the left, turn the steering wheel half a turn to the right as the front wheels just leave to avoid the rear wheels pressing the line; when exiting to the right, turn the steering wheel half a turn to the left as the front wheels just leave to avoid the rear wheels pressing the line. Whether turning left or right, always observe through the large circular mirror to maintain a distance of about 30 centimeters between the vehicle body and the edge line.
