It is caused by the wear or damage of the rod bearings. The connecting rod bearings on the car have considerable clearance, which causes the vehicle to move even more. As the piston shifts direction, the metal begins to collide with other metal, resulting in the knocking sound. As the load and speed rise, the amount of noise produced will increase.

Spark plugs deteriorate and become destroyed with time, resulting in a diminished amount of sparking. When the sparks are delayed, the engine may make a knocking noise as it accelerates, which is caused by the delayed sparks.
