How do you determine duty cycle my injector pw is 11.3 at 5800rpm I am running a 400 with a mini ram 24pd injectors.Thanks for all replys.

 

just for being easy to use.
At 6,000 rpm.
Divide by 60
so you have 100 revolutions per sec.
or
.010 secs
means
10 msec.
The above is for a batch fire system.
To read 11.5 at 5,800 rpm means the injectors are static.

If you remember 10 msec at 6,000 rpm., doing the math gets easy. 20 msec at 3,000, or 100msec at 600 rpm, etc.

In one of the final answer postings, I went into some detail about injector sizing. One quick item is as you approach, 90+% DC the injector opening can get erratic, and the injector just open partically, ie lean, not a good thing.

 

Arrgh,
to continue
Duty Cycle is a percentage of time available for an event.
Actual time divided by possible time is DC

If you had 10 msec at 6,000 rpm, that would be 100% Dutyc Cycle. 5 msec at 6,000 rpm would be 50%.

1 msec at idle (600) rpm, would be 1% Duty cycle.
