Thats what I've been told.
Knocking noise in a diesel is created when the piston skirt hits the inside wall of the sleeve on the down stroke.
And I've been working on them since 1982.
You want a quiet diesel, make it a Gas Turbine.
in a gasoline motor the pistons are installed so the skirt lays flat on the upstroke.
diesel pistons are 180* out so they lay flat on the down stroke.
so you are not really hearing detonation, only the slap of piston against cylinder.
BTW the Cetane #s are supposed to be clearly visible from the pump nozzle.
