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. The actual change from Euro 3 to Euro 4 doesn't correspond to the availability date of Euro 4 injectors but is spread over a period of at least one year. The chart below gives some idea of the distribution of Euro 3 and 4 cars by build date. Note that 130 hp Euro 3 cars become 125 hp as Euro 4 and 155 hp Euro 3s become 152 hp as Euro 4. Ford does show any change in horse power for 115 hp cars. This data is just a sample of 50 cars taken from eBay.
In the Mondeo the transition from long nozzle injectors to short nozzle takes place in June 2003. June 2003 is also the transition date where two box ECU moves to one box. F-Super / Formidable will not read from or program the C2i injector codes with the two box ECUs. I'm not sure about the Transit dates.

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 |
