R34ztune, it's "Corky" Bell, unless you where being funny! On page 183 of his book "Maximum Boost" he discusses VATN turbos however does not get into any downsides yet explains the benefits to being utilized in the SICE. After a little research the main negatives I've found for the VATN is the...
R34ztune, I more agree with trying to gain overall efficiency from the conversion of thermal losses from as an efficient a process as possible. Agreed any time electronic controls can be incorporated in managing the means for gaining the efficiency, the better.
I've built/modified many turbo...
In all the designs including the one posted; am I the only one, but I see lots of parasitic loss and just lots of rotating mass and parts, not much less than what is already in our in-efficient SICE's (or non S) now. Whats your estimated efficiency rating of this? is it multi fuel? What's it's...
"a catalyst after all is to burn the unused fuel." Just a note to that statement. It would be more like the exhausting of spent hydrocarbons and wasted heat energy. With modern cars all the fuel is utilized in the combustion chamber. There is an issue as to how much of the internal chemical...
I can't believe the Chicago school district is going to put them in all there schools. I watched the video with the school superintendent not finding it suprizing however. Why is there no non affiliated third party testing this with qualified equipment? God that bugs me. Some one is a damn good...
Who said anything about "choking the turbine side down"? That was not what I implied and not the only way to gain faster spool up while not changing the A/R of the turbine side.
Your two reasons for utilizing the belt driven supercharger is well understood but was wondering why not hybrid a turbo or utilizing design changes for the turbine side to improve boost response. We mated a Holset turbine and a Schwitzer compressor housing and impeller to achieve the same for my...
Hi Pat, it's been a few weeks since the last entry here and was wondering what you ended up doing/deciding? I had thoughts on this subject. Sometimes the threads just end!
Thermal barriers are designed to keep more heat energy to do work in the chamber against the piston. Yes, intake temperatures are critical. Looking back at SAE papers and in John Heywoods books, developing and maintaining "ideal" intake and or charge temperatures are part of the efficiency of...
I agree with black2003cobra. I didn't see any video's of an operating engine...are there any? Also still sounds like a bunch of parasitic loss there. How do they get 80% efficiency with rotational and frictional losses, unless I'm just not seeing it.
It doesn't seem that anyone mentioned the horrid look of it, or is that just my taste? I agree also, where is or are the working models? The specs don't look like they're written by techs but by marketing and tech editors at best. Am I missing a link to or a video of a working Bike? A Diesel...
Perhaps I'm missing something in your question, but here's some thoughts. I've run Lighter element gasses in my draw through system as well as liquid fuels. Over 35K miles later I've never experienced any problem with my set up. First off we mated a Holset with a Schwitzer to meet my desired...
Some thoughts come to mind:
First I'm a bit confused in regards to the diagrams in your paper. There is heat being absorbed by water to later be used to be injected into the chamber. This will create pressure as you indicate and at some point disassociation. I did notice you keep Low pressure 1...
I read the pdf you listed above. I assume your thoughts are: disassociation of the water molecules would bring the water closer to a phase change that once introduced to the combustion chamber at the proper timing, while incorporating injected oxygen, would create the extra power that was also...
