Dead Center


the extreme position of a piston in the cylinder of a piston engine, at which the motion of the piston changes direction. The piston position at the greatest distance from the crank is known as top dead center, and the position closest to the crank is known as bottom dead center. When the piston is at dead center, its velocity is zero, and the forces acting upon it do not generate an impulse (momentum) for displacement of the crank. In theoretical mechanics the positions of the piston at dead center are sometimes called limit positions (points).
