Why is the motorcycle throttle unstable?

Motorcycle throttle instability is caused by either excessive or insufficient fuel supply. The solution to this issue is to clean the carbon deposits in the cylinder. A motorcycle is a two-wheeled or three-wheeled vehicle driven by a gasoline engine, steered by handlebars to control the front wheel. It is lightweight, flexible, and fast, widely used for patrol, passenger and cargo transportation, and also serves as sports equipment. Broadly speaking, motorcycles are categorized into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and touring bikes. A motorcycle consists of five main parts: the engine, transmission system, running gear, braking system, and electrical instrumentation. The running gear mainly includes the frame, front fork, front shock absorber, rear shock absorber, wheels, etc.

Should a scooter use 92 or 95 gasoline?

Scooters typically use 92 gasoline. 92 gasoline has an octane rating of 92 and a heptane rating of 8, making it suitable for vehicles with lower compression ratios. Whether a motorcycle should use 92 or 95 gasoline depends on the motorcycle's manual and its compression ratio. If the engine has a high compression ratio, it is recommended to use 95 gasoline; if the compression ratio is low, 92 gasoline is sufficient. Scooters are equipped with continuously variable transmissions and automatic clutches, without gear designs. After starting, simply twisting the throttle allows the scooter to move, and releasing the throttle will gradually slow it down until it stops. Additionally, scooters have smaller wheels compared to other vehicles, and most of their transmission systems use belt drives. The difference between 92 and 95 gasoline lies in their iso-octane content. The higher the fuel grade, the better its anti-knock performance. For domestic motorcycles, 92 gasoline is recommended due to their lower engine compression ratios. For joint-venture or imported motorcycles, 95 gasoline is advised. If the engine compression ratio is between 8 and 8.9, 92 gasoline should be used. If the compression ratio is between 8.8 and 9.8, 95 gasoline is suitable. For compression ratios above 10, 97 gasoline is required. It's important to note that the manufacturer sets the fuel grade limit for the motorcycle, so a higher fuel grade does not necessarily mean better engine performance. The specific fuel grade for a motorcycle should be chosen according to the manual.

What to Do When the ETC Light Doesn't Turn On?

If the ETC light doesn't turn on or the screen is black, and there's no response when pressing the top button or inserting the ETC card, it may indicate that the ETC device is out of power or damaged. You can take the ETC device and card to a nearby ETC service center for inspection. If the damage is not caused by human factors, the device can be reactivated or replaced with a new one. Here is some relevant information about ETC: 1. When installing ETC, you need to visit a professional service center to have it installed on the windshield of your car. 2. The ETC device consumes power during use but doesn't require manual charging. There is a solar panel on the back of the ETC device that automatically charges it. 3. For newly received ETC electronic tags (OBU devices), when pressing the anti-tamper switch on the back, the red light will briefly turn on, and the screen will display messages such as 'Tag Invalid' or 'Please Insert Card,' indicating that the device is functioning normally and can be activated.

What are the effects of using 95-octane gasoline in a car designed for 92-octane?

Using 95-octane gasoline in a car designed for 92-octane has no short-term effects, but long-term use can reduce the lifespan of the vehicle's ignition system, fuel injectors, and spark plugs, leading to an earlier need for major repairs. This is the consequence of prolonged mixing of different octane-rated fuels. The appropriate gasoline grade can be determined based on the engine's compression ratio. Cars with an engine compression ratio between 8.6-9.9 should use 92-octane gasoline, while those with a ratio between 10.0-11.5 should use 95-octane. If the compression ratio is lower, 92-octane is recommended. However, with the application of new technologies, the compression ratio alone cannot dictate the gasoline grade. High compression ratio engines can also be tuned to use lower-octane gasoline due to other influencing factors such as ignition timing, turbocharging technology, and Atkinson cycle technology. Generally, higher-octane gasoline has a higher octane number and better anti-knock properties. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. Occasionally using the wrong gasoline grade only requires switching back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles designed for lower-octane gasoline, using higher-octane gasoline will not cause damage, but the increased octane number can alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles designed for higher-octane gasoline, using lower-octane gasoline can cause engine knocking. The significantly lower octane number reduces the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance is generated during the upward stroke, making the engine run very unstable. Mild knocking only increases noise without significant engine damage, but noticeable knocking indicates severe engine conditions, affecting driving stability and causing abnormal wear on pistons and cylinders, potentially leading to cylinder scoring. Gasoline selection considerations: Choose gasoline with appropriate volatility based on the vehicle's operating temperature. Gasoline with good volatility ensures easy cold starts and balanced engine warm-up. However, excessive volatility can easily cause vapor lock in the fuel lines, preventing the fuel pump from delivering fuel properly and leading to engine stalling. Also, consider the lead content when selecting gasoline.

What is the difference between w30 and w40 engine oil?

The difference between w30 and w40 engine oil lies in their viscosity standards: 30 represents a kinematic viscosity standard of 30 at 100°C, while 40 represents a kinematic viscosity standard of 40 at 100°C. The primary functions of engine oil are to reduce friction and wear on moving parts, improve the sealing of piston rings, and cool the engine by dissipating heat from moving components. The viscosity of engine oil changes with temperature, so special attention must be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity—5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity: 0W is -35°C; 5W is -30°C; 10W is -25°C; 15W is -20°C; 20W is -15°C; and 25W is -10°C. Better low-temperature fluidity ensures smoother cold starts for vehicles. The second number represents the kinematic viscosity of the oil at 100°C. A higher value indicates better viscosity retention at high temperatures, which can also be interpreted as better lubrication performance under high-temperature conditions. Generally, better low-temperature fluidity ensures smoother cold starts and better engine protection. Engine oil viscosity should not be too high or too low. If the viscosity is too low, it can increase engine wear. If the viscosity is too high, it can increase engine resistance during operation, leading to reduced power and increased fuel consumption. When the engine is running, the oil forms a film on the surfaces of various components, reducing friction and internal resistance. If the oil viscosity is too low, it cannot form a stable film, which will accelerate engine wear. For full synthetic oil, the recommended replacement interval is one year or 10,000 kilometers. For semi-synthetic oil, the replacement interval is slightly shorter, typically every 7,000 kilometers or six months. When selecting engine oil, consider the following: Choose oil based on the engine's requirements. There is no need to use high-grade oil in engines with lower requirements, and lower-grade oil should not be used in engines with higher requirements. Multi-grade oil is preferable due to its cost-effectiveness, longevity, and efficiency, offering better engine protection. Due to its characteristics, multi-grade oil may appear darker and have lower oil pressure compared to conventional oil, which is normal. Since engine oil significantly impacts engine performance and lifespan, always follow the vehicle's manual for selecting the same series, service grade, and viscosity grade of oil. The oil recommended in the vehicle manual is based on the engine's performance and the regional climate, providing guidance and a significant safety margin.
