Olsryd 9-Cylinder Radial Engine

grabcad

Ok! So a few people in the Grabcad community have uploaded this project in Solidworks format. This is my attempt at the Olsryd radial engine in Pro/E. I will also upload IGES files of the assembly for those of you who cannot open Pro/E files. The engine internals can be animatad in Pro/Mechanism but it will not simulate the valve springs unfortunately. You will need a fast computer to run the analysis! All the CAD files have been modelled from scratch. There is no imported geometry and no files have been used from other GrabCad users. All the parts are fully modelled.by me I've also made some alterations to the design The valve included angle has been reduced from 48 to 42 degrees. This means the valves sit more snugly inside the combustion chambers. The cylinder heads and rocker boxes have been modified to take account of the revised valve geometry and there's more space for adjusting the valve clearances. The engine is timed to be at TDC on the compression stroke on cylinder No.1. The cam drive gears are correctly meshed so that the cam lobes are in the correct position relative to crankshaft position. Engine rotation is anti-clockwise viewed from the front. The cam drive rotates in the opposite direction at 1/8 crankshaft speed. The ignition drive also rotates in the opposite direction. Requested IGS File uploaded 04/02/2015
