who really cares about what bullshit this and that eh? The thread was asking if anyone have heard and/or tried building one, someone with some time on their hands can machine a prototype with steel & aluminium etc. and if someone did it, and connect it up to a microtech or something, it will prove if the theory works or not, but it's just incredible the amount of idiots on this site, if you don't believe in it, then piss off, if you like experimenting and have the required machine and material, try building on for fun, as a hobby~ some people are just plain assholes eh?

lets have a look at some of the bullshit on the site...

"0% harmful exhaust emissions." - as if!! it's combusting (or detonating if you run it lean) a complex hydrocarbon-based fuel - it will have all manner of combustion byproducts like a normal car engine - and if it can run lean, then probably a lot more nasty stuff that your average CAT would normally have to clean up.

I wouldn't know the credibility, but if the exhaust temp. is lowered to what they claimed, then there's a good possibility many harmful gas will be prevented...

"High HP To Weight Ratio." - why does it keep drawing attention to this when it power-output is more likely to be related to fuel consumption and engine capacity?

wouldn't power to weight ratio be related to the amount of junk inside the engine and its efficiency??

thechuckster

"No Oil Changes Needed." - sure? you think that scotch yoke is going to keep that huge center pin rotating with old oil? not a chance.

if the operating temp. is low, and not many moving parts, I would suspect the oil life will be 4-10 times longer than any other 4 stroke engine

Nearly every page of the site directs you to an i8-hosted site that harvests email addresses.

maybe I direct your attention to the first post when I never even posted any web site address? And may I direct your attention again to my second post which mentions these websites are written by third party, this Bourke guy I assume is long dead because may I direct your attention to my second post again which mentions this engine was invented in the early 20s??

Another purpose of the site appears to be to get you to purchase eBooks about the 'inventor' and his scotch yoke engine.

that's the website's author's choice if he wants to make some quick bucks or do what ever with his time

Why are you concentrating on the 'can run really lean and can cope with detonation' story? piston deck destruction has very little to do with the mechanics of the conrod - it's to do with the failed combustion event. The piston and/or head metal fails because it's tried to contain an explosion but has failed. Unless the engine uses diesel-engine pistons then it's not going to cope with super-hot lean combustion that regularly detonates.

the reason why convention engine won't be able to contain the detonation is because the weakest link is at the connecting rods where it blows a hole, I'm sure metal can put up with those little explosions

How about you - 86TT - stay in your little world where every conspiracy theory about oil companies and engine manufacturers hiding wonderful inventions - perhaps you'll find enough time to learn how to cast and machine alloys, machine hard-steel and build your own little 50hp stationary engine?

Have you considered that norbie might actually know what he's talking about? or is everything on the internet the unassailable truth?

i'm not even here to debate if there's any sort of con theories, and not here to debate which knows what they're talking about, because everyone thinks they're the smartest person on earth don't they?

thechuckster

And seriously? who here would build their own engine from raw materials?

It won't be you for sure, but it doesn't mean no one else would, duh!

Say we use petrol as a fuel, and say it offers 34MJ/litre energy. This equates very roughly to 9.4 KWh per litre of fuel of energy potential. If we have an engine producing, say, 200Kw, then it has to use at least 21.2 litres every hour of fuel.

What's this got to do with a 460cc engine producing 50hp in the early 1920s?? what's the current efficiency of today's engine? Why can't another efficient design that is completely different to the 4-stroke be 2-3 times more efficient?
