most different concept for sure..

Is the Adams in question your great uncle?

[Plymouthy Adams]

no kinship that I know of Don...now if this was a record of one being wrecked or raced illegally..maybe...

Betchta that thing has wicked over steer to the left and wicked under steer to the right.

reminds me of a gasoline powered Hunter ceiling fan...connected to a drive line, trunk mounted...

So is that actually a 2 stroke motor?  I remember that some of the radial engine planes in WWI had cylinders that revolved about the crank, with one non adjustable carburetor feeding a central intake port.  They were basically full throttle or off.  For decreasing speed during landing they would be controlled by turning the spark off and on.  Did this for taxiing also. Those planes were notorious for dumping newbie pilots that did not account for the rotational torque.  they would also dive like a banshee to one side and wallow like a pig in deep mud trying to turn the other way

no Greg..view the film..it is a four stoke engine

Very interesting. No need for a flywheel and watch where you put your hands! Nothing new in the automotive world, only refinements.

Some of those WW1 aeroplanes could turn off cylinders ( ground out) to control speed and power otherwise they were 'WOT' as Greg said.

Anyone that has the opportunity to visit The Rhinebeck Aerodrome should do so. During the summer months of course. Well worth the visit for the airshow as well as all of the static displays.

No need for fuel injection or pump....gravity flow downward and then atomizted gas is thown out to the chambers via the external channels....nice!

Stationary crank shaft is an oxymoron.

[48Dodger]

Ooooh....good point.

Guess its just a Shaft, surrounded by crank rods. lol

I see your observation..as in the ceiling fan idea...this crank is acting as a rotor and the pistons as a stator....but the crankshaft still performs its function though locked in a stationary position do to the very reciprocal action of the rod as the cylinder revolve about the lets say offset axis....it is that the whole idea of the rotating crank in convention makes this appear so abstract..personally I see this as one huge gyro...I would guess this was one massive exercise in balancing the rotating assembly..say you parked it for a week and some mud dobbers built their mud nests in the cooling fins of one cylinder..kinda like comparing chopsticks to the modern fork..both will get you fed..but one does have a distinct advantage over the other..and I bet some folks will opt for the chopsticks..

World wide I am guessing the number of chopstick users is as large or larger than fork users.

 

Stationary crank shaft is an oxymoron.

Its all relative. From the frame of reference of the cylinder, the crank (and car and world) are revolving and it is stationary.

OK, frame of reference is an oxymoron

Ever try and eat Jello with chop sticks

[Plymouthy Adams]

little easier than eating the soup...
