This five-cylinder radial engine demonstrator was designed by the Luxxo CAD AI from an engineering-challenge request. It has 64 parts, measures 249 × 237 × 60 mm and weighs 2.2 kg, in steel S235. Below you can read the request, the main specifications and the problems the AI flagged, and download the STEP, STL, DXF and A3 drawing for free.
The request
“Design a cutaway five-cylinder, four-stroke radial engine demonstrator.”
First line of a 14-line brief. The brief demands derived master-rod geometry, a cam ring, valve timing over 720° and clearance checks.
Specifications
- Bore × stroke
- 35 × 30 mm
- Displacement
- 5 × 28.9 = 144 cm³
- Firing order
- 1-3-5-2-4, fires every 144°
- Cam ring
- 3 lobes per track at 1/6 crank speed, opposite rotation
- Master / articulated rod
- 60 / 46 mm
Flagged by the AI
- Articulated rods make the slave pistons deviate up to about 0.8 mm at mid-stroke, so the compression ratio varies slightly per cylinder.
