Stihl 31 ccm FC / FS 44 40 36 (work in progress)

grabcad

This 2-stroke engine comes from a Stihl weedwacker (FC/FS 44/40/36) and has approximately 31ccm displacement. The design is over 20 years old, with work in progress on modeling the cylinder, crankcase, and internals. Remaining components to be modeled include the crankcase cover, inlet port, and exhaust. If you'd like to contribute to the project, renders or simulations are greatly appreciated. Additionally, feel free to download and use the model, just remember to credit the author if uploading it elsewhere.
