Ignition Delay aka ID (Abbreviation for Ignition Delay) refers to a time frame:
- diesel engines - between SOI and self-ignition of fuel mix inside the engine cylinder. Usual ignition delay is considered to be 5° CsR, and varies with cylinder temperature/pressure. With cold engine and partial loads, it may be as high as 10°. In an engine with optimal operational temperature and full load, ignition delay may be as low as 2° CsR.
- petrol engines - it takes to fully ignite the mixture with a spark plug. Typically, 15-35° BTDC depending on the engine speed.
ECU compensates for various engine conditions.
