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 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 more than 18 months.

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 doesn't show any change in horse power for 115 hp cars. This data is just a sample of cars taken from eBay. There are 66 cars represented. Each pink blob is a car and you can read its hp off the Y axis and its build date off the X axis (years are shown along the top). The green line indicates whether a car is Euro 3 or Euro 4. There don't appear to be any 3s in 2006 and there shouldn't be any 4s prior to September 2003.

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
