What Causes Poor Fueling Performance?

[DiAlyssa]

The reasons for poor fueling performance are as follows: 1. Clutch Slippage: Clutch slippage mainly manifests as the vehicle's speed not increasing with the engine's RPM during acceleration. The engine's power is not fully transmitted to the drive wheels, resulting in weak driving performance, especially noticeable when going uphill. 2. Engine Issues: The car's power comes from fuel combustion, and the engine is responsible for supplying fuel and converting chemical energy into mechanical energy. Therefore, when the car experiences poor fueling and slow acceleration, the engine system should be a key focus for inspection. 3. Ignition System Problems: If the spark plugs have poor ignition, leakage, or poor atomization, it can also affect the engine's acceleration.
