Ignition Delay is an concept in internal combustion engine that measures a lag between SOI and start of combustion process.

In TDi engines usual ignition delay is about 5° crankshaft angle at cruise speeds and partial load. In cold engine it could be 10° crankshaft angle or just 2.5° crankshaft angle at full load.

ECU compensates for various engine conditions.
