The Bourke Engine

Hello!
I see there are several posts throughout this forum regarding the Bourke Engine. I am happy to see there is an interest with regard to other possible applications.

The scotch yoke bottom end (crankcase) was specifcally designed to allow for perfect sinusoidal operation. Russell Bourke spent many years figuring out just what the perfect ratio and geometry was for the reverse cam effect scotch yoke design which had been around for decades before his research began in the late 1940's.

The primary difference and what makes the Bourke scotch yoke design unique is that Russell Bourke was the first in history to figure out the correct and best way to use the scotch yoke in reverse.

Prior to that time, the scotch yoke mechanism was used to multiply the torque input at the shaft (crankshaft) into pressure many times greater than otherwise needed to produce work.

After Russell figured out what the best ratio/geometry was, he then discovered imperically a much more efficient way to convert thermal energy into torque (horsepower) from hydrocarbon fuels. This discovery was not simply stumbled upon. It was Russell's primary goal. The 'Bourke Cycle' was born!

More efficient conversion of hydrocarbon fuels to squeeze maximum power out of a pound of fuel than conventional engines could. Russell knew way back then that if engines were not drastically improved upon, many nagative effects on our environment and man kind himself would be suffered. We are now suffering those consequences today in more ways that Russell invisioned back in the 1950's!

The Bourke engine is still to this day valuable and can still make the positive changes that he designed his engine to perform if put to use! It would be a wonderful engine to convert other fuels such as HHO into super efficient rotary power!

Evidently, many on this forum feel that the scotch yoke mechanism itself has other applications and advantages. I agree!

Bourke Engine

Hi David,

I felt for a long time that this engine with Firestorm plugs could probably run on pure hho...even smaller amounts produced by the boosters.

Here are a few posts in regards to a solenoid motor using this system:

For anyone who hasn't seen the concept running on a Bourke Engine, this animated graphic from one of David's websites shows it very well...the links are in his signature of the first message that he started this thread with.

Bourke Engine

Hi,
wow!
Looks like this thread is really screamin with posts! (kidding)
From what I was told, many are interested in seeing the Bourke engine put to different use such as the Teal motor setup.
I am not sure if I want to put in the time to tinker with Teal's setup as it takes lots of time, energy, money and effort to do something like this.
Making the engines connecting rods act as soleniods is a piece of cake provided one wants to wind the coils in the first place which I could do.
Just how much interest i.e. how many of you are truly interested in seeing a real Bourke engine run in this way?

Hi,
I am interested in this type of engine. I already read all the info I could find on it and watched all the videos. I got some serious motor builders extremely interested, but as always, money is a factor. If we get someone with money also interested in this, then we could try to build a small replica of this engine. So far we are thinking of using small pistons and cylinders like those in wood cutting motor saws.
Thanks,
Jetijs

Jetijs, spark the plug like this

Jetijs,

Power the spark plug with this circuit:
YouTube - Water Sparkplug | Electroradiant Event

You may be able to power it by water.

200 CID using 5 1/2 " jugs from a deisel

5.5/2=2.75\ so Pi * 2.75*2.75*4.2099=100*2=200 cid

The Stroke ratio I have chosen "from Russ's guidelines was calculated at 5.5/1.306444... the range is suggested as an application guide. ie: Long stroke gives greater HP, I chose the shorter stroke to get Lower HP at any given rpm.

Jetijs, Aaron, David
I would concur that it should be possible to build any size engine. I have long thought that a small enough engine could easily run on hydroxy gas, but really it all comes down to getting the parameters correct. I want to know what the bore is in the 30 CID engine. if I could get that I would be off and running to construct a 10% model. Furthermore, Russ suggested relying on already made parts like rings; Knowing this will allow you to customize your build. After doing some calcs, I would figure the 30 CID is supposed to be 3" Bore and 1 1/2 stroke figured and a 1.4 ratio for the stroke.
BTW, if you adhere to the notes Russ said approximately 1.33-1.66 area for the stroke calculation you should be in good shape.

One of the most serious obstacles is in harnessing this rotational energy.
I will design a clutch system that will qualify for this task. Essentially there are designs that use an "over-center lock", that you can apply whatever pressure "adjustable", you want that can be set at the pressure you desire. So if yo go beyond that pressure the clutch plates will slip until the driven shaft matches the input rotation speed.

I have started serious contemplations about building some of these engines.

Everything to me seems like a strategy in essence so Lots of thinking before building.

I have a lathe, Most attachments that I need; however, I must to put together a fantastic foundry to cast parts and equipment. I need more space in my shop,

I have talked so a couple of the forerunners in this quest who have serious desires in seeing this technology flourish.

Please get in touch with me if you have any documentation that is relevant. Ideas or fumbles you see....

Zane

Ideas for successful Bourke cycle engine

I talked to two of the mechanics where I work and received a couple of ideas that will make figuring out the supplies and details to make the start of your build much easier.

Look for a motorcycle type engine at junk yards that have 4 cycle independent jugs. From there Pick up the complete engine. You can use the block to make molds of the attachments to the cylinders and melt down all unneeded aluminum. You can also use the pistons to cast your own blanks because the original pistons are not designed for the Bourke application. The diameter needs to have an interference tolerance and the top of the piston must be fashioned to allow the intake and exhaust transfer ports to operate correctly. You will also have the correct sized rings to fit your new pistons. No guessing, you can order new from the factory. OEM parts.

I thought about this while talking to my brother and now it just dawned on me that the stroke is not going to be correct but "what the hell", So what the stroke is may be negligible at this point. I guess I should get one and find out how if possible I could make this work. My inclination would tend to make me believe the stroke is going to be too large to use the same crankshaft but on second thought; here is the scenario.

Crank say 2.5" Normal stroke
Crank with scotch yoke "let's say 1.75"
So now we have 3/4 " to make up at the bottom of the cylinder. This can be easily done by Extra metal spacers at the bottom where the Rod seal is. This would take up the space needed to get the precharge in the correct balance to measure 50 psi for the transfer port.




Just a little help.
Contact me with any Ideas help or fumbles
