There will be a problem of excessive engine sound, and many car owners have been troubled by this problem. What exactly is causing the loud engine sound?
1 There is carbon deposit
Because old engine oil becomes thinner with use, more and more carbon deposits accumulate. When the engine oil is thin, it is easy to channel the oil, causing more and more carbon deposits and losing a lot of power. When new engine oil is replaced, the engine cannot adapt to the viscosity of the oil, which may increase the speed, causing the engine to be noisy.
2 sound insulation
If you hear the engine running normally outside but feel the noise is too loud in the car, it means your vehicle has poor sound insulation. The vehicle’s seals should be inspected to see if there are any signs of aging. Or increase the sealing effect of the vehicle and try again to see how the noise is.
3 coolant
Everyone knows the role of coolant. When its temperature is too low, problems are likely to occur, and the engine noise will become louder. This should be checked and replaced to avoid other problems.
4 shock absorbers
Everyone knows the role of shock absorbers. Generally, when passing a speed bump, we can feel whether the shock absorbers on the car are good or not. When there is a problem with the shock absorbers on the car, the problem of loud engine noise will occur.
5 Deflagration and detonation
When knocking occurs, that is, after the spark plug flashes, the end combustible mixture spontaneously ignites. At this time, the flame center formed by the spark plug igniting the mixture and the new flame center formed by the self-ignition of the end mixture are in opposite directions and at the speed of impact. spread, producing a sharp knocking sound and increasing engine noise.
