deleting an HCCI engine
#2
(12-08-2019, 05:56 PM)6T56 Wrote: HCCI engines are heavily reliant on egr gas to control combustion and keep cylinder temps in check. If the egr gas is removed you lose the ability to control combustion and with such high compression ratio's you will certainly have cylinder temp and pressure to high right? How is all this accounted for in the delete programs?

you would need to take this heavily into account.  Completely redoing the timing maps and editing any modifiers to the managers with a retard across the board.  Then obviously charge flow will have to be heavily remapped to reflect this removal of EGR to run safely and keep cylinder pressures in check.

If not you melt it down, lower the final crank angle and take out the crank/wrist pin/rod, put a hole in a piston, or crack the head and push the gasket.

There is much more but this would be the general overview.
