AI Thread Summary
The discussion centers on the efficiency comparison between a one-moving-part Rankine engine and a Stirling engine. One participant claims that their research suggests the Rankine engine could outperform the Stirling engine but lacks mathematical proof to support this assertion. The conversation highlights the importance of mathematical validation in scientific claims, emphasizing that without it, the argument lacks credibility. Participants stress the need to consult existing literature and professional studies to substantiate claims about engine efficiency. Overall, the debate underscores the necessity of rigorous analysis in evaluating engine performance.

Can a one-moving-part Rankine engine be more efficient than a Stirling engine?
 
Engineering news on Phys.org
Welcome to PF.

What has your research so far indicated?
 
My research indicates that a single-moving-part Rankine can out perform a Stirling but I don't have the math to prove it ... :-(

The "math to prove it" would depend on numerous factors. What do you think those might be? Under what circumstances "can" it happen?

Which appears to mean your personal attempts to wave your hands.

Have you looked at the literature to see if any professionals in the field have investigated this topic, and if so, what they found?

Without math you're just waving your hands. That's not a good way to investigate a scientific question.
 

Thread 'A practical way to vaporize fuel for high MPG?'

Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...
