<HTML>There have been lots of discussions on different types of possible burners for steam generation but I have not heard mention of injection carburetors as used on aircraft for this purpose. The books I have show what is just a carb body with a low pressure injector in it and the meetering system that controls it. The injection carburetor has a couple benefits over a standard carb including operation at any angle, complete shutoff of the fuel when the throttle is off (no puffs of smoke from unburnt fuel) and pressurized fuel feed for easier, more accurate tuning under varying conditions.
Has anyone ever experimented with or built any of these devices ?</HTML>

<HTML>Peter,
Sounds very interesting, do you have any sources of info for them?
Essentially the Doble cab and the Fish carb injected the fuel into the carbureter throat as the fuel was under a few inches of water pressure, not sucked in like a regular carb.

<HTML>Peter,
Yes, did once work with a Bendix injection aircraft carburetor from an Allison V-1710.
The only reason for this type was to insure constant mixture when the plane was inverted or othwise flying in anything but level flight, like in combat.
Hard to get, very complex what with all the ancillary controls and for a steam car, totally unnecessary.
Today the now abandoned single point injection carburetors that G. M. used would surfice; but are needlessly complex for a steam car burner.
Forget it, unless you are planning on driving upside down.
