    Any Actual Need For Pilot Injections Other Than Cold Weather Cold Starts?

    I can totally see the need for the pilot injections for cold weather cold starts, to pre-warm the combustion chamber for the main injection event, but after warmup, it seems to me that there is no use for the pilot injections other than noise management, and emissions (limiting NoX). Anyone know if this is true?

    My inclination is to get rid of pilot injections after the warmup cycle, and see what that does to my efficiency.

    There are some discussions in the Cummins section of the forum on single event tuning, might get you headed in the right direction
