Duty Cycle

[Kev.O]

Had a quick read, but i couldn't find anything that explained why its used, as i said, cant see a reason for it, have to ask Richard for an explanation.

 

I couldn't find a reason, just presumed it was required, hence why it was in there. Thanks for looking Dick.

Is it possible that the restrictor is being fitted to match the pressure with the injector?

As its worked out as pressure drop over area perhaps the original pressure/flow is worked out with a certain sized injector if you used a larger injector then you may need to restrict the flow to maintain the pressure.

 

Hope that makes sense

Cant see how this would make any difference to water injection as the pressure is and should be constant, and needed to ensure good atomisation from 0.2mm up to 1.00mm jets, any restriction would compromise that, the injector as such HSV, in essence behaves like a fuel injector, but it is in fact remote from the jet, so is just a metering device, any restriction after this would have a negative impact on the jets atomisation, especially when using the larger jets.

Right, i was looking at it from the point of view that it would be a constant flow pump of a set value and then you match a restrictor to whichever atomiser you decide is appropriate. In which case you would need a restrictor as the restriction to the flow = pressure.

From what you posted i assume the difference is that little as to be a negligeable effect
