Why so much smoke???

[AMassaro]

I'm still learning this diesel performance thing, so take it easy on me guys...



What I'm trying to understand is why these boxes, especially TST and VA duration boxes cause SO much smoke.

A- The smoke is showing an inefficient burn and/or a very rich mixture (I know it's different from gas to diesel but that's the best way I know how to describe it).

B- If we could make less smoke with the same fuel, we'd make more power, no? (more efficient?)

C- Why can't someone find an optimal combination of pressure, duration, timing and boost (twins, compound, or correct single) that will make 500+/1000+ with minimal smoke?

It seems like with todays technology, this shouldn't be that hard to do. Maybe I'm way off base or I don't know my a** from a hole in the ground. . :-laf

you are right, well on boost anyway. it should run clean, i. e. no smoke, or at least very minimal, or it is just waisted fuel. off boost the throttle response can be greatly increased but create smoke. an egt gauge is like an air fuel gauge for a diesel. it should have enough air to keep cool and enough fuel to make the power.

It can be done. Take a look at "AK RAM"s video in his sig. 12. 91 with no smoke.
