It may well be that I've misunderstood the 30% efficiency I've read in several places.Maybe the number was supposed to represent overall efficiency,and wasn't clearly stated.But this is what I wanted.Someone telling me where I'm wrong.Not just dismissing everything.If I've made a mistake,I want to know where it is.Thank you.I misunderstood overall efficiency figures to represent combustion efficiency figures it seems.But other then that,am I in the right ballpark in understanding the other basic comparisons with different types of engines?
Tom W.the thread that origionated this was "Regular instead of Super!???".
It started about fuel saving ripoffs.I described the most common one that keeps popping up useing magnets on the fuel line,and brought up two vapor carb designs I know of that seem to work fantasticly.I got ridiculed some and got very frustrated over the matter.I admitted that in my opinion,at least 80,000 miles worth of testing should be done before anyone could say any vapor design can be said to work exactly as claimed.Now I'm trying for a good discussion of the three main factors determining engine efficiency.So far so good.
I'm currantly suffering due to broken back and fractured neck pain,which makes concentration difficult at times.So I'm sorry to all here that I can't remember exact numbers alot of the time.Or where some of my info originated anymore.But I still remember all the basic theories.And I remember all the applications to my many years of experience as a mechanic.That's why I can't make exact quotes for you here in most cases.But I'm not ignorant either.And I'm more then willing to learn what I don't know,or be corrected where I may have confused some facts.
