and some detalied calc on how you got this too pls
STRONG SELL phimx wrote
2. To increase the D13 by 20% requires a Stirling with an output of 55.93 kW, approximately a 9 fold output of the existing in-spirit Stirling. Totally impossible !
It is that simple. Show me I'm wrong !!!!!!!!!!!!
and this one to how did you come to this detailed calcs pls
1.A 20% increase in output from In-spirit's Stirling, to 7.68 kW, can only improve the 375 HP D13 by 2.7% . The paper you cite, a theoretical WHR proposition, improves efficiency by 6.7%
come on....sonny...wheres the calcs? ......promise we wont laught .....honest
Oldblue: You write “ so how did you get the 7.76kw? detalied calcs pls”
Are you saying you cannot figure out where 7.76 kW came from? You want detailed calcs of 20% of 6.4 kW ? I think this is maths for 10 or 11 year olds.
You also write “ how did you figure out the burner for the charger is 100 kg” The answer is in my post it says “the Charger weighs 350 kg but you don't need the burner. So a wild guess, 250 kg”
Do you understand what a wild guess is ?
those arnt detailed calcs still everyone one off them below pls all 3 with detailed axb/c etc calcs not....
Are you saying you cannot figure out where 7.76 kW came from? You want detailed calcs of 20% of 6.4 kW ? I think this is maths for 10 or 11 year olds.
what is 20% of 6.4kw you do realise that the 20% is for the volvo penta heat exchnager and not the charger.... 6.4kw is the modulated max output off the charger and has nothing to do with the vovlo penta heat exhanger??
yes i think this is maths for a 10-11 year old...

1.A 20% INCREASE IN OUTPUT FROM IN-SPIRIT'S STIRLING, TO 7.68 KW, CAN ONLY IMPROVE THE 375 HP D13 BY 2.7% . THE PAPER YOU CITE, A THEORETICAL WHR PROPOSITION, IMPROVES EFFICIENCY BY 6.7%”
Admittedly if you have trouble with simple percentages this might cause you a lot of grief. So now we have established that the Charger output has increased by 20% to 7.68 kW, how does that affect the D13.
Well the purpose of using the Stirling engine/Charger is to gain some additional useful work from the huge amount of energy that is blown out of the exhaust to the atmosphere. Are following ?
Since the Stirling can produce a total of 7.68 kW from this waste heat, it adds to the output from the D13 without using additional fuel.
Now another one of those tricky percentages coming up.
The D13 produces 375 HP from the lowest power output engine. Now go online and find out what 1 horse power is in Watts. I’ll save you the bother, you may spend all day doing that. 1 Horse Power = 745 W. So how many HP is 7.68 kW. Very tricky, watch carefully
7680/745 = 10.3 HP. Very sly of me, I changed kW to Watts.
Voila, the Stirling produces 10.3 HP. Now that represents … percentage alert...
10.3/375 = 2.75 %
So the D13 has produced an additional 2.75% more output by adding the Stirling.
So the next big problem, at least for you ! If you wanted to increase the output of the D13 by 20% how much electricity would the Stirling have to produce.
Percentage alert … 20% of 375 HP = 75 HP. We need a Stirling from In-spirit to produce 75 HP. BUT in-spirit don’t Have such a thing, they only have a device purportedly producing 10.3 HP. They would need to start all over again and design a massive Stirling engine and they are incapable of that!
well that proved it really.....dont ever ever design anything it will fall down or blow up...key thing below and if you dont realise what im saying im wasting my time with you....
and by the way i have actually designed/routed diesel generator exhaust lines.......
what is 20% of 6.4kw you do realise that the 20% is for the VOLVO PENTA HEAT EXCHANGER (stirling test)and not the CHARGER.... 6.4kw is the modulated max output off the CHARGER and has nothing to do with the vovlo penta heat exhanger?
and because off the above what you have below is nonsense
the 6.7% is for the rankine cycle they tested which wasnt enought to be viable (according to that paper)we seem to be able to produce 20% (stirling engine test)again this is for the VOLVO stuff and has nothing to do with the CHARGER...all imho etc etc
and that nonsense below is nothing to do with me and quite frankly anyone with minor engineering would be rolling around the floor laughting
so the stuff under
Oldblue: You write
is nothing to do with me but is phimx's work nothing to do with me at all just to clear that up
oldblue, better to not type and be thought a fool, then to respond and confirm it...
im sorry but did your hired help just make a fool out off himself? have you read the rubbish down there?
Oldblue: I think I'll let others decide who is the fool.
Oldblue: Read In-spirit's words
" During the demonstration, the novel three stage heat recycling process increased engine efficiency by approximately 20% ...
Engine efficiency increased by 20%
You waffle on about heat exchangers, they aren't mentioned.
Which engine efficiency increased by 20%. The Stirling or the D13 ??????????????
Try and put together a coherent answer i.e.
The Stirling
or
The D13
ok here goes note i give the rns you dont
https://www.lse.co.uk/rns/INSP/product-update-d9it7ko3xw1k3hi.html
The WHR system utilises Inspirit's proprietary Sterling engine technology, and its compact nature enables it to be positioned in the exhaust system after the catalytic converters with the energy being directly transferred as an electrical output. During the demonstration, the novel three stage heat recycling process increased engine efficiency by approximately 20%, driven by waste heat from e.g. a Volvo Penta D13 series engine. In addition to the efficiency improvement and heat reduction, the WHR system is also expected to have the additional significant benefit of reducing noise.
all there if you cant understand it.....ild go back to pschiatrity
phimx wrote below and this stuff below is gold......lol

and i found this on a google search looks genuine enought to me

looks like they tried a rankine and only got 6.7% efficency table 4.10?
from below looks like they have done the same process and got 20% and that was 3rd nov 2020
this as always all imho etc etc DYOR!!! amazing what you can find on google if you get thro the adds...
now director share holding note the price 0.0725!!!! now he must off know this was coming as we gave him the authorisation to do it with the agm so hes bought from GIS to himself at 0.0725 and is now diluting himself...???

The Company announces that yesterday John Gunn, Chairman and CEO of the Company acquired 78,569,746 Ordinary Shares in the Company from Global Investment Strategy UK Ltd ("GIS") via a market transaction at a price of 0.0725 pence a share. John Gunn is Chairman of, and a 52.89% shareholder in Octagonal Plc, which wholly owns GIS.
placing for 1 billion shares

The board will also be seeking other opportunities that it considers will best enhance value for shareholders.
should find out on thursday there abouts with a tr1 i for one am really looking forward to see who bought them
all imho etc etc DYOR and good luck everyone that actually owns shares!!!

So you are saying In-spirit increased the D13 efficiency by 20%. So the Stirling produced 75 HP from the waste heat i.e 20% of 375 HP.
Where did In-spirit get this huge amount of electricity from, it certainly wasn't from the only Stirling they have been supposedly developing for the last 10 years, which supposedly develops 10.3 HP ????
It was all a modelling exercise. Now to produce that 75 HP they need to design a far bigger Stirling..... From scratch.
its like teaching physics to a child
http://www.crayola.co.uk/
To others: it seems obvious to me that the In-spirit Stirling had its efficiency increased by 20%. Perhaps we could have guessed that. So what we know is if we blow the exhaust from a 375 HP engine costing £60,000 we can get an extra 1.28 kW from In-spirit's Stirling engine. But what do Volvo get ? An extra 2.75% efficiency, pretty poor improvement considering the additional cost and weight.
Oldblue: where does the 75 HP come from??
do you just come up with random numbers do you have one off those randon number balls?
Oldblue: how will In-spirit produce 75 HP from their 10.3 HP Stirling to improve a D13 by 20%
You don't have a clue do you ?
Oldblue: You're in good company though, because John Gunn doesn't know how they are going to do it either.
phimx your trying to calculate stuff which we dont have the info to calculate and are just looking silly please stop
