4 cylinder in-line compressed air engine

3D model description

In-line 4 cylinder engine running on compressed air and printable in 3D (with some additional elements like ball bearings, screws, O-rings, plastic balls, inner tube seals...).

The engine exceeds 3500 rpm with the 10x5 propeller tested.

The single-cylinder version was created by Tom Stanton, I first derived a two-cylinder version then a three-cylinder version and finally this 4-cylinder version.

There are a lot of modifications compared to the monos, bi, and tricyliners, especially on the crankshaft.

The whole is assembled with 2mmx8mm screws.

All this is detailed in the editing video

Motor operation up to 70Psi !

I only have to create the V6 version to finish this series on compressed air engines;)

filament used: PLA

print height: 0.15mm

3D printing settings

You don't need supports, all supports have been included into the design.
