Why did Detroit diesels consume so much oil?

Given the huge difference between thier engines power density and the comparison engines on thier site one can only assume that the comparison engines are infact 4-stroke engines. I bet an ordinary direct injected 2-stroke engine with the same displacement as the OPEC engine would perform...

That 2/4 stroke engine is a good idea. I wonder how it would work with a multi plane crankshaft.

Here's a link showing the great interest direct injected 2 strokes are recieving from manufacturers. http://www.snowgoer.com/output.cfm?id=1836523.

Patprimer Untill a couple of days ago I hadn't even heard of Orbital. Please dont dismiss what I'm saying on the sole grounds that it sounds like a sales pitch.

The link to the scooters is here http://www.orbeng.com.au/orbital/directinjection/motorcycle2s.htm.

Modern direct injected 2-stroke scooters have lower emissions than thier 4-stroke equal displacement catalytic converter toting compatriots and weigh less, further widening the efficiency gap.

Why build a 4-stroke over a two stroke? Assuming both engines utilise direct injection a 2-stroke is fundamentally better is it not?
