What Does TDC Stand For?
TDC stands for Top Dead Center
Top Dead Center (TDC) refers to the highest point in the cylinder of an internal combustion engine where the piston reaches its uppermost position. This critical position in the engine's cycle is essential for determining timing and performance, as it marks the end of the compression stroke and the optimal point for spark ignition in gasoline engines. Accurate knowledge of TDC is vital for engine tuning, valve timing adjustments, and ensuring efficient engine operation.
