The reasons why a scooter cannot start include: 1. Incorrect ignition method: Pressing the ignition switch without twisting the throttle may fail to start the engine. In such cases, try twisting the throttle appropriately to check if the ignition method is correct. Some riders may prefer twisting the throttle excessively when starting, but this can make it harder to start the engine and may cause the spark plug to malfunction. 2. Improper maintenance: Check the following in sequence: whether the fuel level is sufficient, whether the spark plug electrodes are functioning normally, whether the engine oil level is adequate, whether the rated operating temperature of the oil is higher than the actual temperature, and whether the air filter is clogged. Different grades of engine oil are suited to different temperature environments. Using high-viscosity oil in low-temperature conditions may make it difficult for the engine to function, leading to startup failure.

When my scooter fails to start, I usually consider several common factors. The most frequent issue is battery problems, such as insufficient charge or aging failure, especially after prolonged parking. If pressing the start button yields no response or only a clicking sound, it's likely a battery issue. Then there's spark plug damage or carbon buildup causing ignition failure, manifesting as the engine turning over but not firing. The fuel system shouldn't be overlooked either—low fuel levels or a clogged carburetor can starve the engine. Once, my bike stalled on a rainy day, and it turned out to be water in the fuel tank; it ran fine after cleaning. Compression system failures like piston or cylinder leaks are rarer but worth checking in older models. For safety, I recommend checking the battery and fuel level first—it saves effort and hassle. Don't make my mistake of rushing to repairs only to regret not acting sooner. Regular maintenance can prevent most troubles.

Why Does the Engine Sound Louder After an Oil Change?

The reasons for a louder engine sound after an oil change include: 1. The oil viscosity does not match, which can easily lead to carbon buildup, causing the engine noise to increase. 2. The main function of the exhaust pipe is to expel exhaust gases and reduce engine noise. If there is an issue with the exhaust pipe, the engine noise will definitely change. 3. There are more and more counterfeit oil products on the market, so car owners should pay attention to the quality of the oil when purchasing. 4. Excessive oil can create significant resistance, affecting power output, increasing fuel consumption and carbon buildup, reducing engine power, and causing excessive noise.

How to Obtain a C4 Driver's License?

c4 driver's license is processed at the local vehicle management office and requires an examination. In some areas, the theoretical test for the c4 license has been delegated to district vehicle management offices, allowing applicants to obtain the license by passing the test at these offices. A c4 license permits the holder to drive three-wheeled motor vehicles (originally three-wheeled agricultural transport vehicles). Below are the contents of the C4 driver's license examination: 1. Subject 1: The test typically consists of answering 50 questions, with each question worth 2 points. The test duration is 45 minutes, and a passing score is 90. 2. Subject 2: Pole weaving test: The test site is set up with several iron poles, usually spaced three meters apart. The examinee must navigate a motorcycle in an S-shape through the poles back and forth once, without crossing the boundary lines or stepping on the ground with their feet during the ride. 3. Subject 3: The test mainly includes recognizing various road signs, understanding traffic police hand signals, and knowing how to handle different situations while riding a motorcycle.

What are the reasons for low pressure in car air conditioning?

Here are the reasons for low pressure in car air conditioning: 1. The opening degree of the expansion valve (or orifice tube) is too small. 2. Insufficient refrigerant in the system. 3. Blockage in the expansion valve or low-pressure side. 4. The compressor runs continuously, or the variable displacement fails. The following are the functions of car air conditioning: 1. It is used to adjust and control the temperature, humidity, air cleanliness, and air flow in the car compartment to the optimal state, providing a comfortable riding environment for passengers and reducing travel fatigue. 2. It creates good working conditions for the driver and serves as an important ventilation device to ensure safe driving.

Should Engine Oil Be Changed When It Turns Black?

Engine oil has a certain lifespan, limited by both time and mileage, and does not necessarily need to be changed just because it turns black. There are several methods to determine whether engine oil should be replaced: 1. Smell Test: Pull out the dipstick and smell it closely. If there is a strong sour or foul odor, it indicates the oil has deteriorated and should be changed. 2. Rub Test: Take out the old oil and rub it repeatedly between your thumb and forefinger. Good-quality oil will feel smooth, produce little grit, and cause no friction. If you feel impurities, poor viscosity, or even a rough texture, it should be replaced. 3. Color Test: Place a few drops of old oil on a clean white filter paper. After the oil seeps in, high-quality oil will leave no powder, feel dry and smooth to the touch, and show a clear yellow infiltration zone. If it appears dark brown or black with impurities, it should be changed. 4. Light Test: Hold the dipstick at a 45-degree angle under light to observe the oil droplets. If the droplets are clear with no visible grit, the oil is still good. If there is a lot of grit, it should be replaced.

What is the function of the OFF button in a car?

The OFF button in a car is used to turn off the vehicle stability control system. The vehicle stability control system is enabled by default. If you need to disable it, press and hold the OFF button. The function of the vehicle stability control system is to intervene when the vehicle is taking a high-speed turn and the front or rear wheels, which have driving and steering functions, start to slip. The ESP (Electronic Stability Program) will automatically brake other wheels and intervene with the engine management system to prevent skidding and loss of control. There are several situations where you might need to turn OFF the system: 1. When the vehicle is stuck in mud or sand during off-road driving. 2. When aggressive driving such as drifting is required. 3. When snow chains are installed on the vehicle.

How to Apply for Vehicle Inspection in Another Province?

Currently, the traffic management authorities have fully implemented cross-province inspection for small cars, trucks, and medium-sized buses. Applicants can directly inspect their vehicles and obtain the inspection certificate in provinces other than the vehicle's registration location without needing to go through the entrustment inspection procedure. However, large passenger buses and school buses cannot be inspected in another province and must return to the vehicle's registration location for inspection. Inspection time requirements: Small and micro non-operational passenger vehicles are exempt from inspection for the first 6 years. For vehicles older than 6 years but less than 10 years, inspection is required every two years; for vehicles older than 10 years but less than 15 years, annual inspection is required; for vehicles older than 15 years, inspection is required every 6 months. Operational passenger vehicles must be inspected annually within the first 5 years; after 5 years, inspection is required every 6 months. Trucks and large and medium-sized non-operational passenger vehicles must be inspected annually within the first 10 years; after 10 years, inspection is required every 6 months. Imported vehicles, like other vehicle types, can undergo regular inspection at any inspection station. Inspection precautions: Vehicles that fail inspection must be repaired within a specified time limit. If they still fail after the deadline, the vehicle management office will confiscate their license plates and prohibit further driving. Vehicles that do not undergo inspection without reason or fail inspection are not allowed to drive on roads or transfer ownership. Vehicles that meet scrapping conditions or exceed the prescribed service life will not be inspected, and their license plates will be revoked, their records deleted, and they will be scrapped.
