What is the reason why the scooter cannot accelerate when the throttle is applied?
1 Answers
Scooter's inability to accelerate when the throttle is applied is most likely due to a fuel supply system malfunction. A decrease in the engine's compression ratio can also lead to a reduction in power. If there is too little fuel in the engine, the air-fuel mixture becomes too lean, which results in insufficient gas thrust on the piston after ignition, prolonging the combustion time and causing the engine to generate very high temperatures during operation. If the air-fuel mixture in the engine is too rich, it can cause the scooter to feel sluggish during low-speed operation. Additionally, a clogged air filter can lead to a decrease in power. A clogged air filter can cause the carburetor float level to rise too high, blocking the carburetor's main air passage during engine operation, thus resulting in reduced power. The use of poor-quality fuel in the engine can also lead to a decrease in power, and using gasoline with an incorrect octane rating can cause engine knocking during operation. The engine's power is directly related to its compression ratio. If the engine is used for a long time, internal components will wear out. If some of the main components in the engine wear out, the engine's compression ratio will decrease, leading to a decline in the engine's efficiency.
