cylander presure is the reason for det in a petrol engine as well
and timing will not always fix it
run to lean ... you get det and burnt valves
run to rich .. you get bore wash
run to much timing you get det and burnt valves
run to little timing you get massive egt's
run to much compresson .. you get det
run to little compression.. it wont go
then we go onto cam phasing air intake temps the quality of your swirl and tumble boundry layer effects pulse tuning of the intake and the exhaust, valve material
there are so many reasons you get det its not funny in a petrol engine .. seriously
if all you have to do with a d is thrown in fuel and boost untill it goes bang then you have it easy
petrols and more specifically 2 strokes make d's look like kids playfrom a tuning aspect
so please ... dont make it sound like a petrol is eazy ... when its far from it
The point was, you can't use timing on a diesel to avoid detonation. If you've got it, then a few degrees of advance or retard won't stop it.
Basically you've gotta pull any fuel that can detonate, right back to where it won't.
well honestly thats simple stuff ant it ... do you think det sould go away by itself ?
welcom to the world of getting the most you can from a engine
