[11] Air Pressure Engine (Pneumatic) - 6 cylinder (V6) - 348 ccm

This is a working model of a V6 engine.

Video: https://youtu.be/xf3Yl7T8agw

Specs:

• Version: 11
• Type: V6 (60°)
• Displacement: 348 ccm (58 ccm each)
• Min. pressure: 2 bar (29 psi)
• Max. tested pressure: 7 bar (102 psi)
• Max. speed: ~1000 rpm

Warning:

• This project does not contain instructions. I wouldn't recommend printing it. Use it as inspiration to design your own model.

Note:

• The model in the video has the old camshaft. The new camshaft has improved performance by around 60%.
• I've used regular PVC pipes as cylinder sleeves to reduce friction and improve the seal of the piston rings (like seen in the previous model).
• The timing belt is not printed. Check out details below.
• It took me nearly 200 hours to print all the parts using an Anycubic i3 Mega S. Keep that in mind.
• Additional parts as bearings, belts and screws are expensive (~100$).
• Sanding down the pistons will take some time.
• There will be no more work/updates on this model.
• You'll need a huge compressor to run this thing.
