This is a reciprocating engine working on the four strock cycle in two crankshaft complete turns and in a radial arrengement ;
There is one master connecting rod to wich is atached an even number of slave connecting rod , the master connecting rod is linked to the crankshaft via the master pin . This arengement is very easy to cool by air and is very short but not aerodynamic efficient
movie 1.328 MB warning this is a big file !
it show the cinematic of the valves ; pistons ;connecting rods ; and crankshaft during one complete cycle
ps the tooted gears may seem to spin backward ! this is due to the computer display refresh rate being somewhat a multiple of the number of tooth that passed at a given place during the time between 2 frames (stroboscopic effect)
