WebNov 17, 2024 · Luckily, finding Top Dead Center (TDC) in an engine is far less taxing from a theoretical standpoint. TDC refers to the position of the Number One piston relative to the deck surface of the cylinder block. This is used as an indicator for at least two of the more critical aspects in an engine: ignition and cam timing. WebIn both types, each full rotation of the crankshaft produces two strokes of the piston, one moving inwards towards the head of the cylinder, followed by a second which withdraws the piston back to its initial position. A 4-stroke engine fires once every second rotation of the crankshaft (every fourth stroke of the piston).
