The actions taking place in the engine cylinder can be classified into four stages or strokes. “Stroke” refers to piston movement. A stroke occurs when the piston moves from one limiting piston to the other. The upper limit of piston movement is called TDC (top dead center). The lower limit of piston movement is called BDC (bottom dead center). A stroke is piston movement from TDC or from BDC.
