Injection volume?

[MeTo]

I’m tinkering with a scenario which requires known injection volume demands. I.e. max fuel volume injected per second, revolution and etc… I forced the order of operation. The quantity is obviously wrong, but I don’t see where?

A basic 90 cc HEUI injector:
(((90cc (injector volume) x 8 (cylinders)) x 1700 (7.3 4 stroke@ red line)) / 946.353 (cc/qrt)) / 60 (seconds) = 21.56 qrts/sec or 5.39 gl/sec

So what’s the madness to all this questions? What are you trying to achieve?

90cc per 1000 strokes

90cc per 1000 strokes

Ahh, I don't remember seeing that. Thank you sir.

According to your equation your OBS redlines at 1700 RPM. Does it really redline that low?

I have a 94.5 and redline is at 4k rpms

With a four stroke, the injectors fire every other stroke. So for calculation purposes, just divide the redline by two. I assumed this was obvious?

It seems obvious after you mentioned it. :doh:
