Well the Fawker is at it again... trying to elevate his status by making degrading statements about folks he clearly knows nothing about... IMO the Fawker is likely an insecure and resentfull, social invalid, wanna be substandard engineer who has some fantasy of actually doing something cool but he's stuck in some office calculating the strength of a beam for someone who is actually building something cool.... when anyone else comes along and suggest anything he doesn't understand he slams it... Example: He think his IDI comet combusting chamber is as efficient as DI even though most every one else in the engine engineering world states a 5-7% increase in efficiency for DI over IDI... I guess all those engineers are wrong... there also seems to be confusion about other subjects such as increasing the expansion ratio, larger bores being more efficient and this pesky little broblem of comparing one engines efficiency to another... he thinks it just can't be done... bottom line? I guess it's hard to maintain superiority when you have a closed mind and clearly don't understand the subject matter...
Kiss my ass.
DI has an approx 5% thermal efficiency that IDI, thermal efficiency is only one of the components of efficiency.
Charge mixing efficiency is another one, and IDI beats DI hands down, especially at low RPM, by a wedge more than 5%
Fuel vapourisation efficiency is another one (the injector doesn't do all the work) and again IDI beats DI hands down.
Charge combustion pressures ramp and lot nicer with IDI than DI, and this is another source of efficiency.
DI on the other hand is a LOT cheaper to make, cuts cylinder head costs by as much as 20%, and considering cylinder head cost can account for 30% of engine costs that is a lot of money.
"All those engineers" are not wrong, they are just being selectively quoted by the marketing droids, the engineers in question don't get to speak in a public forum.
Fatty you seem to think this is some sort or popularity contest or barracking at the hustings, the one who can get most people to side with him is the victor and thus proven right.
It don't work that way, right is right even if nobody believes it, because basic engineering principles don't care if you even exist, much less what you choose to believe in.
You lot are all the same, you roll out the same tired old snippets that are always quotes from somewhere else, and when challenged on them the pot is empty and you have no more to give.
NOT ONE SINGLE basic fact or reasoned argument have you been able to come up with.Your entire argument basically boils down to GF is a wanker.
When I was a punk kid and getting to motorbikes in a bad way (after years spent fettling english iron) I bought all the japanese bike marketing bullshit too, and I used to go on to my old man about all the fabulous new things the japanese had invented and developed, nothing new under the sun, he said, I, like you, said rubbish.
He then said, if you can find any japanese bike with anything that is a genuine innovation, I will personally buy you any japanese motorcyle you like... now I was working and could afford any new japanese motorcycle anyway, but you never look a gift horse in the mouth.
The (long) conversation went like this.
me - OK, honda have made a water cooler vee four
dad - so? AJS made a water cooled vee four in 1933, and it was blown too.
etc

You talk now like I did back then, you talk like someone quoting shampoo adverts, ooh it's got lipids, ooh it's hypo allergenic, ooh it's recommended by the blah foundation.
You don't realise that lipids are just bunches of molecules that congregate in spherical form and are hydrophobic, hypoallergenic is not found in ANY medical dictionary, being a term devised by marketers in 1953 to sell a cosmetic by making it sound medical, and the blah foundation is not an independent government / medical body, but a trade foundation owned and operated by the cosmetics manufacturers.
You got all the buzzwords, but you don't even realise that basically you are talking shit.
Shall we eat this tub of axle grease labelled margarine A with LDL lipids or margarine B with HDL lipids, because hey WE NEED TO LOWER OUR BODIES CHOLESTEROL.
Do we? Seeing as cholesterol in MANUFACTURED by the body (about 2 grams a day) because the body needs it as an essential building block for our sex hormones and vitamin d. SO even if you understood all those buzzwords, which you don't, you go and buy some food product thinking it will lower cholesterol, which it won't, because 85% is produced IN THE BODY, while labouring under the impression that lowering your cholesterol is a good thing, which is isn't, unless you want to be a eunuch with a vitamin deficiency.
No, ALL THAT STUFF IS MARKETING BULLSHIT, it sure sounds technical, that is the idea, but it doesn't mean anything except BUY ME NOW!
================
NAME ONE SINGLE DIESEL ENGINE MANUFACTURER who offers any engine in DI or IDI, just take your pick.
just name one.
You can't
You don't know enough to understand why.
When pressed all you have is marketing sounbites, your knowledge lacks any depth, so you revert to ad hominem attacks against those who would point this out to you.
Twice now I've said $100 your blower design has prior art. Why won't you discuss it? not sure of yourself? or is this a project that doesn't exist anywhere outside of a CAD drawing? Or is it that merely making statements is enough in your world?
I am currently working on a desktop cold fusion device.
