Waste Motor Oil / Re: Is it possible? Combustion chamber size?

Richard With a siphon nozzle the compressed air will siphon the fuel through
the nozzle. The metering pump is a pump that pumps a small (metered) amount of
fuel through the nozzle. If your system needs 1 gph this pump will pump 1gph.
I built my own metering pump using a J type fuel oil pump (I think any type
would work) coupled to a DC gear motor and a speed controler that I could vary
the speed thus vairing the oil output. Just bench tested this by timing run
time and measuring output. The DC motor I got had a max speed of 100 RPM and my
max output is over 1 GPH. I found the DC motor on e-bay for around $50and the
speed controller was about $50 also, the pump I had from an old burner. So I
don't have much invested but have been very happy with the results. Hope this
helps
