Rotary engine – how it’s made and how it works!


The rotary engine was an early type of internal-combustion engine, usually designed with an odd number of cylinders per row in a radial configuration, in which the crankshaft remained stationary in operation, with the entire crankcase and its attached cylinders rotating around it as a unit. Its main application was in aviation, although it also saw use before its primary aviation role, in a few early motorcycles and automobiles.

In a conventional piston engine, the same volume of space does 4 different jobs – exhaust, combustion, compression and intake. The rotary engine does the same 4 jobs but, each happens in its own part of the housing. In this engine there is a cylinder for each of the 4 jobs, with the piston moving from one to the next, continually. ┬áIn the video below you can see how a rotary engine is put together and after that you can see how it actually works!
