Ford IDI injector specifications.
Spray pattern on IDI (Indirect Injection) injectors means nothing. The fuel is sprayed into a precup which has a rough interior that breaks up the fuel into small droplets just before combustion.
An IDI Leaking injector is NOT considered as Leaking when POP Tested if the droplet holds in place on the "Needle/Nozzle" for a period of Five (5) seconds.
An IDI Ford/Navistar Diesel engine is Factory timed to 8.5* to 9.0* BTDC using the pulse method @ 2000 RPM. The Factory quartz pulse pickup is located on #1 injector on a Truck engine and is located on #4 injector in a Van engine. At those spec's, fuel is injected at 23/1000 of second BTDC.
