Tomorrow I'll finish grabbing a second set of manifold to play with, I'll be installing boost/intake temp/EGT/EGP sensors along with rebuilding the turbo.

As part of an independent study I am working with retrofitting existing diesels to use ethanol air stream injection to reduce diesel consumption/increase performance(in bursts). Why ethanol? Another student is working on a system for farms to make ethanol from waste silage, and this will tie in with it.



As for performance; why couldn't you add a nozzle to squirt alcohol/water into the exhaust PRE-turbo? This could in theory causing it to spool up on-demand giving you more off the line. Match that with injection in the air stream, and in theory you've got a nice little boost.

I was thinking of adding either one nozzle at the EGR port, or 5 evenly spaced along the manifold. I'll probably do both and record measurements, they call it a study for a reason, right?


As for fuel economy, we are assuming that the alcohol is homebrewed and around $0.75/gal worst case scenario


I need more holes in my project, so let loose with any/all comments!
