DB2 IP Fuel Flow Duration

[WisdomWarlord]

Can someone tell me for how many degrees of crankshaft rotation does a stock DB2 IP and stock N/A injectors flow fuel in one injection event?

Thanks

PM Mel or as he is known here Agnem, he owns www.conestogadiesel.com and can likely answer that for ya and then some!

I'm betting its probably about8 or 10 degrees of crankshaft rotation. If you think about it we advance the timing around 9 degrees so thats where the injection starts. Where it ends is somewhere just after top dead center a couple of degrees. I will be watching for some answers to this question from Mell also.

That would depend on what the calibration is for the fueling. So there is no hard and fast answer. The more throttle you give it, the longer it is going to take to squirt that much fuel in, and . If your talking about the maximum amount of time that the cam lobe can spend injecting fuel, the theoretical maximum would be about 10 degrees, but that would mean the roller is riding on the cam all the way around, and you definitely don't want that.
