[Diy_efi] Diesel EFI?

[Frey, Richard K]

I was under the impression that one of the big advantages of the CRD is that the injectors can inject fuel and various times during the power stroke.  That is to say a pilot flame is initiated at one point, injection of additional fuel at different times as the piston travels downward.  So, the ecu would have to be able to open the injector at various times and durations during one power stroke.  I am not sure that the megasquirt can do that.  Then again, I am not necessarily up to speed on the megasquirt capabilities.  Absent taking advantage of such injection timing, I'd think the mechanical injector would be just as good.  Certainly simpler.

Guys, this is my first post to this list!

I have been reading most of it for a couple of years now ...
I have an old Toyota Diesel truck so I was unable to work on an EFI project (it has the mechanical injection pump).

Recently I was thinking about 2 options, one is changing the pump to a common rail setup, and then put in an EFI system that controls the Injectors.
2nd option is getting a new Toyota D4D engine (without the ECU) and adding an EFI system to it.

I was thinking about MegaSquirt, as the last V3 is supposed to be able to provide sequential Injector signal ... Is it enough for a Diesel?

I would appreciate any comment on the subject!

Thanks,

Yakir Green
