Wrong injector type

Hello,

Yesterday I found that on my 1.9JTD 85kW engine are fitted wrong injectors. Bosch code is 0445110002. It seems they are from older engine model 77kW. The correct injectors should be 0445110119. What is the injector class of the older type? Now it is set to class 2. Is it correct? Can it cause any problems if I use incorrect injectors? Car runs without problems except smoke of unburned diesel on cold start.

I'm not sure but injectors are rated with a maximum flow rate, so it could be that injectors for one engine (77kw) might be the same as on a more powerful engine (85kw).

How do you know they're the wrong type? Did the car come with those from new, or did you buy it second-hand?

Some year ago injectors were changed in local workshop. Old ones were leaking. I was told replaced injectors were also used, but in good condition. Accidentally I compared part numbers in ePER and Bosch of existing and old ones, and I see that I'm using injectors from 77kW (CF2?) engine.It is interesting can it cause some problems, for example burned pistons due different spray pattern or similar?

It *could* .. I'd guess the injectors might initially deliver less fuel than the injectors from the more powerful version... though the ECU and sensors would be able to work out that the mixture is too lean and tell the injectors to spray more.

It'd probably run okay... but if those injectors were perfect for the engine, then Alfa would not have used the other type. The other injectors (019) are the proper ones for the car for a reason...

I don't know what the precise differences are... but the 002 or 019 number could describe the shims/spray pattern of the injector etc. since the rest of the part number is the same, so the 019 injector is mostly (but not 100%) identical to the 002.

looks like they are different see the chart listed in post 75 here

1.9 8V 74kW CR-IPS19-ZEREK10S-BOSCH 0 445 110 119 DSLA144P1295 6x 0,165

1.9 8V 85kW CR-IPL17-ZEREK20S-Bosch 0 445 110 276 DLLA142P1607
judging from that data the number of holes size and spray angle is wrong, unless is there any chance they had fitted nozzles from a 119 injector to body of a 002 injector ?
theres a pdf below that chart to compare part numbers

here you can compare flow
Attachment 421081
they don't look too far apart in flow figures id bet its hard to tell if you did swap in fact those 002 have higher total flow
0 445 110 002 CR/IPS19/ZEREK10S Fiat >18,4 >73,6 140 145 150 8,2 9,2 6,4 9 10 3,2 4 4,8 3,4 4,8 5,2 5,5
edit wrong injector 019 instead of 119
see below for 119 data
the response time is slightly slower on the 002 at 145 vs 135 again probably not notice.
if in doubt consult a local injection specialist for a chat even the guys who did the job, they may explain differences in more detail, or even do a deal on refitting 119 injectors ?

Thank you for detailed information. But you took 019 figures instead of 119. Anyway I think I have lean burn wtih all consequences I don't think workshop has fitted 119 nozzles on 002 body.

well spotted ,my mistake.
0 445 110 068

0 445 110 088

0 445 110 119 >23 >92 130 135 140 10 11,5 8 11 13 4,4 4,8 5,4 3,8 6,4 6,8 7,4


0 445 110 002 >18,4 >73,6 140 145 150 8,2 9,2 6,4 9 10 3,2 4 4,8 3,4 4,8 5,2 5,5

ok these do look a fair bit lower but as you say you will be on lean side of normal so more mpg and unless your short of max power ?
