Doyle Rotary Engine

[Lonny Doyle]

For those of you that do not know me my name is Lonny Doyle.

I too have designed a split cycle engine that is quite different than the Scuderi and Tour Split cycle designs.

I own a small CNC aircraft machine shop that we use to design and build our prototypes. We also use the machine shop to fund our research.

I was told by some engine investors that the reason they invested was that independent research had shown that the engine had great potential.

So we now have an independent lab working on a P/V diagram that will estimate the potential efficiency of the DRE. It will be interesting to see what they come up with.

On a side note we have been trying to complete the latest prototype as funds permit. We are very close. Hopefully we will have it ready to test in the next few months.

Keep working Lonny because I believe you can do it. When you get to the point of investors don't forget to send me an invitation.

Can you give an idea how long you think it will take to develop an engine the size required to run one of these mammoth generators?

[Lonny Doyle]

If I had unlimited funds, (5 million or so) I feel I could have one ready for testing in less than a year.

The DRE has quite a few less parts than the Scuderi engine so it makes the task of building and testing a little less daunting.

If that is true they may be able to deliver the first engine for the PPA they have just received. I didn't think they could get it done within that time frame - and I know you are only giving your opinion but your opinion means a lot to me.

We have finally received the first draft of the research on the DRE cycle.

It is far more extensive than I expected.

The team that worked on it started by creating a model to describe the conventional Otto cycle to establish a base line.

They then modified it to describe the DRE.

They supplied us with an Excel model that allow us to change the timing of each event and also the physical dimensions of each component. We can use this to quickly see how the engine responds to different setups. 

I have attached the final report, I had to break it in three parts because of the file size limit of the forum.

My son is still working on updating the Doyle Rotary site with the PV analysis by UTA, information about our recent Doyle Cycle prototype and other progress updates. He made a single informative page so that we can start sharing our info: DRE Info Page

Let us know if you find any typos or if there is anything needs to be clarified. Also, Adam says that the site might not be optimized for every device so if you have problems viewing things on your ipad, phone or computer please let us know so he can fix them.

Hey Lonny,

There is one spelling mistake. Under "End Goal", first sentence, optimised should be optimized.

Other than that it looks good. Easy to read, not too much clutter. Great job.

Lonny, building the two cylinder in line split took 14 days or .......14 month's?

[Lonny Doyle]

14 days

Thx

Hallo Loney,

Lots of  new relevant information (your site),

Have to find the time and carefully learn it.

That's the right approach to move forward.

Thx

Have you been able to build the proto-type, has it been tested for effeciencies?

[Paul]

Peace out!
