What Does ATDC Stand For?

ATDC stands for After Top Dead Center Gasoline And Diesel Engine Timing

ATDC, or After Top Dead Center, refers to a specific timing measurement in the context of gasoline and diesel engine operation. It indicates the position of the piston relative to its highest point in the cylinder, allowing for precise timing of fuel injection and ignition. Understanding ATDC is critical for optimizing engine performance, improving fuel efficiency, and reducing emissions in internal combustion engines.
