Why does the Geely Boyue's engine RPM not increase when stepping on the accelerator?

[DeIan]

There are many reasons why the engine cannot reach the desired RPM, including engine component wear leading to reduced power, increased resistance due to tire wear or insufficient tire pressure, road conditions, wind direction, wind force, driver experience, and traffic conditions. Clutch Slippage: One of the most common reasons for the car's speed not increasing when stepping on the accelerator is clutch slippage. Clutch slippage is mainly characterized by the car's speed not increasing with the engine RPM during acceleration, as the engine's power is not fully transmitted to the drive wheels, resulting in weak driving performance, especially noticeable when going uphill. The primary cause of slippage is insufficient friction of the clutch friction plate, such as shifting gears too early or disengaging gears improperly, prolonged driving in a semi-clutch state, coasting with the clutch pedal depressed, incomplete gear engagement or disengagement, or applying excessive throttle when the gear is not fully engaged, leading to abnormal wear of the clutch plate. Engine System: Of course, if the car's speed does not increase when stepping on the accelerator, it could also be due to issues with the engine. The power source comes from fuel combustion, and the engine is responsible for providing fuel and converting chemical energy into mechanical energy. Therefore, when experiencing weak acceleration or slow speed increase, the engine system should also be a key area for inspection.
