Sleeve Valve Engine Model

thingiverse

Attend the Reno Air Races to witness engine sounds that are truly incredible, especially the Sea Fury's Bristol Centaurus engine, which produces a unique low and smooth sound due to its sleeve valve design. However, building a model of this complex engine may be challenging. Alternatively, consider the simpler sleeve valve design used in radio control airplanes, like the one found at http://www.rcvengines.com/how-it-works.htm. To create a fully printable, snap-together model that demonstrates the four strokes of a 4-stroke engine, assemble two parts: the sleeve and upper casing, and the drive shaft, crank, handle, rod, and lower casing. Pin these together, ensuring proper gear mesh alignment and positioning, before securing with clips. Observe how the model's gears simulate intake, compression, expansion, and exhaust strokes when cranked in the designated direction. Note that the arrow on the lower casing was made to stand out through pausing and changing colors during printing using Sailfish firmware.
