What is the significance of the "20 secondish" time frame? There are easy solutions if you take your tiem. Freddie

Hello! HELLO! WHERE IS EVERYBODY? Are Russ and Cliff and me the only ones interested enough to post on this thread? I waited a long time, hoping someone else would speak up. But no one did. OK.RE McLaren Mercedes Formula 1 team: When you are pushing the limits of a technology, one of the...

I think a lot of readers of this thread did not do the arithmetic! Russ says "Maybe 10% in power and 3 to 5% efficiency." I said that if all the wasted heat could be used, the improvement would be 70/30 = 2,33 times. Obviously, 2.33 is less than 10% or 5%. OR IS IT? 2.33 times is 230 PERCENT! I...

I stumbled across a website that shows combustion pressure curves for normal operation, knocking, and water injection. There is also some detailed text under the graphs. With 1644 hits, I guess a lot of people are interested. For the graphs, go to...

This thread overlaps one on the General Engineering forum titled Vapor Carburetion. It looks like a lot of people are interested in getting better gas mileage by adding the high priced miracle additive known as H2O. Freddie

Russ: "Some of the energy added by the water injection is energy taken away from the regular Otto cycle" Exactly right. But the mechanical energy involved is trivial. The tradeoff is that you are taking energy from a high temperature source (initial combustion) and using it to create steam...

better fuel efficiency thru vapor carburetion The website reference got mangled in copying. The one I was trying to reference was: http://kahuna.sdsu.edu/testcenter/testhome/indexclosedcycles.html insert: /testhome/indexclosed cycles.html This is for an Internal Combustion spark...

Greetings to all: I have found a really neat website for anybody interested in Internal Combustion engines and related Thermodynamics. Go to http://kahuna.sdsu.edu/testcenter/t...osedcycles.html HOWEVER: This presents an Introduction to some important concepts and thus leaves out some other...

Dieudonne: Go to Google and look up Magnetic Levitation. Find the pictures in How Things Work or similar sites. Freddie

My apologies to all. I just discovered that I do not have permission to access this page. And I don't know the routines that I need to get authorized. So thanks to all who participated in what I thought was a worthwhile discussion. Just goes to show ya. Freddie

Rahool: Forget the whole thing. My apologies to all. I just discovered that I do not have permission to access this page. I don't know what the procedure is. So you can just discount everything I said. Hey, if I'm not authorized, obviously, I don't know nuthin'.

Russ Waters: I think a lot of people are interested in engines, but it looks look you and I are the only ones following up on this thread. From a textbook reference on automotive engines: Approx 15% to propel the car, 15% for power train and engine friction. All the rest are HEAT losses. If we...
