Atkinson Cycle Engine

[Tom T]

Here is some pictures of a Atkinson Cycle Engine I built last year. This engine makes all 4 strokes in a single turn of the crankshaft and each stroke is a dfferent length.I measured them on this model and got power 1.250 exhaust 1.5 intake .75 compression .5 :roll:
The plans where by Vincent Gingery. I added the radiator.
I am now building this engine in super size. Will post pictures soon.

That's a pretty piece of model work.
You know I have to ask if you have a running video.....
I'd love to see that in motion.

Great work!!!!

Lovely bit of work there Tom.
As Rick said, got a vid to let us admire it even more.

Quite an interesting engine Tom.

What RPM does it tick over at?

Do you have a close up of the center of the crankshaft that shows the exhaust push rod workings?

Nice looking engine, Tom. Do you have much problem with vibration?

Kenny the engine has a regular carburtor and can be varied from about 200 to 1300.
Chuck it runs smooth no vibrations.
I will try to get a video up . Tom

Hi Tom,
I'm a newbie in this interesting forum and I saw some minutes ago your great Atkinson cycle engine from D. Gingery.
I'm planning to build one in the next months too.
I want to cast the flywheel with an ZN / AL alloy. For a former IC engine I casted
the flywheel with this method too.
My actual question is the following:
The weight of the flywheel with my kind of alloy is twice as much as the AL-flywheel of the Gingery version.
The original crankshaft has a diameter of 11.1 mm. Do you think a 15 mm
crankshaft diameter for the AL / ZN alloy ( density is about 5 ) is strong enough ?

kind regards from Germany
