super efficient engine design


Try putting your elbow on the table with your palm up and dropping a bowling ball from the ceiling on to your palm, and then rethink your statement. The pressure in a combustion chamber at (TDC) is about 2000 psi it has been tested and just like when the ball hits your palm. Then move your elbow off to the side of table and catch the ball again that is like 90 degrees to the crank. Then you can see your own test data. I can only give the test data when engine is built.

Confusing power density with efficiency.
Could you please expand on your statement? It makes no sense to me.

The bowling ball might apply more torque to your elbow at 90 degrees, but this has nothing to do with efficiency, and does nothing to support your claim.

I don't like people throwing around credentials, but you should understand that there are experts here. I am a professional engineer and have spent the last seven years developing internal combustion engines. I analyse data (or predictive data) to make judgements on efficiency and this is the only way to make progress.

In an earlier post you said that you base your claims on earlier tests. For the third and final time, please share this data.

i base my claim on tests from models years ago and i have answers for any question.

It is a fact that it takes as much energy or force to stop a mass in motion, as to start it moving again. If that energy or force drives a shaft at a total mechanical advantage at 90 degrees is that not more efficient? If the heavy pistons push against the cylinders back and forth through compression and combustion, four times per cycle and the cylinder is attached to the gears that drive the shaft, would this not be more efficient ?
I would like to talk more about of the technical issues on building a test model.

So you have no test data, and no thermodynamic arguments to support your claim of very high efficiency. Sorry, that's not how we do things here at the PF. If you can produce either of those things, send me a PM. This thread is closed for lack of scientific content.
