There are several different things that can cause a piston to fail. One common cause is excessive wear and tear. Over time, the piston rings can become worn, allowing oil to leak into the combustion chamber. This oil can then burn, creating deposits on the piston head and スカート. These deposits can eventually build up to the point where they interfere with the piston's movement, causing it to shake.
Another common cause of piston failure is overheating. If the engine runs too hot, it can cause the piston to expand and seize in the cylinder. This can also cause the piston to warp or crack, which will further exacerbate the shaking.
If you suspect that your car is shaking due to faulty pistons, it is important to have it diagnosed and repaired by a qualified mechanic as soon as possible. Driving with faulty pistons can cause further damage to the engine, which can be expensive to repair.
