Not always, sometimes yes, if you have 21:1 compression ratio (NA diesel) Turbo diesels are usually 16-19:1. If one wants to use E85 and convert it with spark plugs and all that, I don't think that 21:1 with turbo will work?
In study they had turbo diesel TDI engine and that has 16.5:1 compression I guess?
So to get it to work, it is perhaps needed to lower compression a bit to level they had in that study?
That is why I would like to read whole study to learn more parameters from it so I could tell what would be needed with application in my mind.
