What Causes the Slight Grinding Sensation When Accelerating?
1 Answers
The causes of a slight grinding sensation when accelerating include deteriorated engine oil, belt slippage, and clutch wear. Below are detailed explanations: 1. Deteriorated Engine Oil: Over time, engine oil gradually deteriorates. Engine oil has a service life and needs to be replaced when it expires. Additionally, if the oil becomes contaminated or degraded, it should be replaced promptly. Failure to replace the oil in time or the use of deteriorated oil can increase friction between components such as the cylinder valves and guides, as well as hydraulic lifters, leading to abnormal noises when accelerating. Solution: Replace the engine oil. 2. Belt Slippage: Parking in rainy conditions can cause belt slippage. When a belt slips, it produces abnormal noises. Belt slippage generates high friction heat, causing the belt to stretch further and worsen the slippage. Solution: Visit a repair shop to adjust or replace the belt. 3. Clutch Wear: The clutch is prone to wear over extended use and requires regular maintenance. If pressing the accelerator results in the vehicle revving without proportional power output, this indicates slippage—often due to worn clutch plates. A grinding noise may indicate damage to the clutch release bearing. Solution: Visit a repair shop for replacement or servicing.
