cycles

[Phil Lamovie]

Hi John et al,


...but an engine cycle is 720 degrees and therefore, at 7000RPM,  with
an 80% duty cycle the max pw is 13.7ms.

Yes John your quite right a 4 stroke IC engine has a working cycle
that
encompasses 720 degrees of crank. On the other hand an Injector is
not any IC engine and has a duty cycle that is of one revolution only.

This does of course give rise to the question... are you only
injecting every second revolution of the engine ? If so that may
establish part of the reason for the stumble you are experiencing.

Phil
