Fuel injection time change
Fuel injection time change
(OP)
Hello everybody:
For stationary medium speed, Miller Cycle engines, burning residual fuel oil Nº 6, in order to improve their performance (mainly with the fuel consumption), some ideas have been proposed.
One of them is to change the fuel injection time. At this moment, the start of injection is at 12º BTDC and, it is proposed to change it to 11º BTDC.
Even when in a general manner I know what happens when the injection time is delayed, I would like to hear your comments in this forum.
Thanks in advance.

Thanks to all for your comments.
BrianPetersen: actually, I do not know what is the timing for the maximum torque output for these engines.
In the beginning of commercial operations that timing was 11,4º BTDC. Almost a couple of years later, the manufacturer recommended to change it to 12º in order to improve the performance.
Nowadays, after a lot of gathered experience (and not a few problems) some people are suggesting to return back to 11º.
