Common Rail Injector Types

Mondeo & Transit Common Rail Injectors

This information is a combination of data from Ford parts lists and a useful catalogue from United Diesel that was pointed out by Mondysteve.

The Month / Year dates generally agree between the two sources but these should not be taken as vehicle build dates.

In the Mondeo the transition from long nozzle injectors to short nozzle takes place in June 2003. I'm not sure about the Transit.

Injector characteristics are shown here: http://www.merlindiesel.com/media/Delphiinjectortestplans.pdf

Below is a plot of the injected fuel volume of four of the common injector types for comparison.

The table shows the test point rail pressures and injection pulse widths:

Idle	Light Load	Mid Range	Mid Range	Max Fuel
250 bar	400 bar	800 bar	1200 bar	1600 bar
700 uS	600 uS	600 uS	1200 uS	1600 uS
