I have an idea that essentially stolen from many different sources. Russell Bourke is the first person that I found to have made this engine back in the 60s. I want to make one also. I have found a bunch of papers and some plans for the engine. Unfortunatly none of the drawings show any dimensions. But everything is scaled correctly so I can add dimensions fairly easily... My friend is good at CAD drawing (or so he says, i have yet to see it.) And i hope that he get's the program here so that i can start making the pics of it. I dont know exactly how to draw this thing out, but i'd love to make it in cad so that i could bring it to a machine shop of some sort and have them make it.
Some may know this engine as a VLB engine, or a Vaux engine, or a Bourke stroke engine. It has a scotch yoke instead of a crank (dont know the difference, from what i can tell it's the same) The pistons are set up similar to that of a boxer engine in the WRX. if you look up bourke engine in google or mamma you'll see what i'm talking about. I want to make something that i can make an adaptor plate for so i can have it in my car. Supposedly it's supposed to run 20:1 A/F which is rather lean, but apparently any richer and it doesn't work right. It is similar also to a 2 stroke in that when the piston goes to TDC it makes a vacuum sucking in air and fuel, but because of something it doesn't need the same oil in gas thing. One web site suggested using a ECU to control the exhaust valve...but i dont know if i like having an exhaust valve yet. He was talking about useing that if his engine was running at 20k. That speed would work great if i had a hydrolic drive train. But they were talking about how you keep the engine at a constant speed and have the pump do all the variable speed stuff... exactly the same as a locomotive, or a big-o-mine truck (i lived on the iron range in MN, so i know some of the trucks)
but rousell was attempting to make his run with the same old trannies as everyone else had.
Here's my idea. Since the engine is relativly small and easy to work on, i was going to just start by making it carbed, and 2 stroke (no ecu) I want to have the scotch yoke sick out both ends and have identicle ummm..bolts? so that on one end i can bolt up a crank pulley. and on the other end i can hook up either a tranny or another engine. (so that i can make a 2,4,6,8 cylinder...what ever a person wants) Supposedly this thing makes gabs of power at 2k rpm so i dont think it would really be necessary to make an 8, but i wouldnt' really be making it cause you'd just bolt 4 engines together. Since they all run independant one could effectivly blow up and i could still run the vehicle.
Most all the ideas in my head are just someone elses drawings. (except the hole bolt up thing) I just want to make a better engine for my self. If someone else wants it i can get him/ her all the stuff they need to make it their selfs either. Or if your in the area (knoxville TN) i'd be glad to do the work my self... (i'm one of those shade tree mechanics anyway so i'm cheap...PRICES)
First actual question:
Does this seem at all interesting?
Any one know any body that will build something that i make using autocad?
what size should my pistons be? (i was thinking about grabbing the same size as the f22)
but i dont much understand if it's a 87mm bore does that mean the piston measures 87mm? or is it smaller to allow for the rings to fill in the gap?
Any suggestions?

oh by the way good write up you seem pretty intelligent
