Motorcycle starts but won't move due to automatic centrifugal clutch failure, drive belt breakage, or spark plug burnout. Below are specific explanations: Automatic centrifugal clutch failure: Improper clutch operation causes it to get stuck without returning to position, resulting in the motorcycle starting but unable to accelerate or move. A faulty automatic centrifugal clutch requires replacement or repair. Drive belt breakage: Usually caused by pulley or belt malfunction. The rear transmission system needs to be disassembled for inspection. If the belt is broken or has significant gaps, it must be replaced. Spark plug burnout: Water ingress or blockage in the carburetor leads to spark plug burnout. Check if the fuel line is clogged. Loosen the bottom screw of the carburetor to let gasoline flow for a while before tightening it. If dirt enters the carburetor, inspect the spark plug. The carburetor needs cleaning or replacement after prolonged use, and a burnt spark plug must be replaced.

What to Do If You Fail the Subject 4 Exam?

Subject 4 shares many similarities with Subject 1 in terms of test items, but Subject 4 focuses more on practical driving experience. Therefore, during preparation, it's essential to review questions thoroughly, practice extensively, and consider how you would react as a driver in similar real-life situations. This approach not only reinforces your understanding of the questions but also greatly benefits your future driving on the road. Subject 4 is just "one step away" from obtaining your driver's license—passing it will make your dream come true. However, if you fail the Subject 4 exam, don't lose heart or be discouraged. Remember, as long as you are within the 3-year validity period of the driving test, the number of retakes for Subject 4 is unlimited, unlike Subjects 2 and 3, which allow only 5 attempts. The 3-year validity period starts from the date you passed Subject 1, not from the date of your driving test registration. During the exam, face the test content head-on without avoidance. Reflect on your mistakes and deductions from each attempt, adjust your mindset, and strike while the iron is hot. Don't give up hope—trust in your abilities and maintain a positive attitude. Take the exam seriously in terms of tactics but lightly in strategy. Don't fear the test. Persistence leads to victory! Everyone is a winner!

Does Using the Heater in Winter Increase Fuel Consumption?

Using the car heater does not consume any fuel. Here's a detailed explanation: Principle of the Heater: The heat generated by the heater actually comes from the engine's heat. If the driver doesn't use the heater in summer, the heat is dissipated through the radiator cooling cycle. When using the heater in winter: Part of the heat generated by the engine is used to cool the engine after passing through the radiator, while another part enters the car's interior through the heater ducts. Therefore, using the heater in winter does not increase the vehicle's fuel consumption. The so-called increase in fuel consumption is because it takes longer for the engine to reach its normal operating temperature in winter compared to spring, summer, and autumn, which naturally leads to higher fuel consumption, but this is unrelated to using the heater.

Can a National 5 Vehicle Be Upgraded to National 6?

Generally, vehicles meeting the National 5 emission standards cannot be upgraded to National 6 emission standards. Specific Regulations: The National 6 emission standard is an upgraded version of the current National 5 emission standard. It imposes stricter limits on the emissions of CO (carbon monoxide), THC (total hydrocarbons), NMHC (non-methane hydrocarbons), NOX (nitrogen oxides), and PM (particulate matter mass) compared to the National 5 standard. Additionally, it introduces new regulations on PN (particulate matter number) emissions. Emission Regulations: According to estimates, under the National 6 emission standard, light-duty gasoline vehicles will see a reduction of approximately 50% in carbon monoxide, hydrocarbons, non-methane total hydrocarbons, and nitrogen oxide emissions compared to the National 5 phase, with particulate matter emissions reduced by about 40%. For heavy-duty diesel vehicles, nitrogen oxides and particulate matter emissions will be reduced by more than 60% compared to the National 5 phase.
