Injector - Fuel Injection Timing
Check actual fuel-injection advance vs design - the indicator-diagram sanity check for 2-stroke or 4-stroke engines.
Δ timing
1.50°
Status
Early - reduce pre-stroke / VIT
Formula, assumptions, and limits
±0.5° is the tuning tolerance. Early injection → high Pmax + NOx. Late → high EGT + reduced efficiency. Modern common-rail systems adjust electronically.
