What are the reasons for the particularly loud engine noise in the Lavida?
1 Answers
Lavida engine noise is particularly loud for reasons including carbon deposits, poor sound insulation, low coolant temperature, shock absorber noise, or engine knocking and detonation. Carbon deposits: As engine oil becomes thinner with use, carbon deposits accumulate. Thinner oil can lead to oil leakage, causing more carbon deposits and significant power loss. When new oil is added, the engine may not adapt to the oil's viscosity, potentially increasing the RPM and resulting in louder engine noise. It is recommended that owners clean the carbon deposits promptly. Poor sound insulation: If the engine sounds normal from outside but noisy inside the car, it indicates poor vehicle sound insulation. Check the vehicle's sealing strips for signs of aging or improve the sealing effect to reduce noise. Low coolant temperature: When the coolant temperature is too low, issues may arise, and engine noise can increase. It is advisable to check and replace the coolant to avoid further problems. Shock absorber noise: Shock absorber performance can usually be assessed when driving over speed bumps. If there are issues with the shock absorbers, engine noise may become louder. If problems are detected, it is recommended to replace the shock absorbers promptly. Engine knocking and detonation: Knocking occurs when the spark plug ignites the mixture, and the remaining combustible mixture auto-ignites. This creates opposing flame fronts that propagate at high speed, producing sharp knocking sounds and increasing engine noise. Owners should check and replace the spark plugs as needed.
