The Incredible Shrinking Engine

Have a look at this, I stumbled across this and found it an interesting read.

This would have been news if it was 1950.

just a we bit old technology.

'Turning on a car's turbocharger...'

Uhhh what the??

[Black_Widow34]

how can this be old if it has not been used yet? i know there is 100 octaine petrol with ethenol but thats different to this...

i hope this is a joke...

did you all read it properly? yes they use a turbo, but they use the standard type fuel injection (injectors firing before the valves), then they have another injector built into the head to fire ethanol into the cylinders on the compression stroke when the valves are shut.

there must be something about engines that calms him down.........

I think some people are not getting it,

This is a quote taken out of the article...

"Cohn and his colleagues have created a design that they believe could triple the power of a test engine, an advance that could allow automakers to convert small engines designed for economy cars into muscular engines with more than enough power for SUVs or sports cars. By extracting better performance from smaller, more efficient engines, the technology could lead to vehicles whose fuel economy rivals that of hybrids, which use both an electric motor and a gasoline engine. And that fuel efficiency could come at a fraction of the cost"

Now to me that sound like a bloody good idea.

Remember we are talking about direct injection and not throttle body injection with the use of ethanol.

Now is put the question out, can this be done to a throttle body injection were simular results can be achieved, 2x or more power out put with unbelievable fuel economy.

these things have been around for years, theres always some new engine design around, yet theres only 1 main design that we still use (i think rotaries are still in too smaller numbers to count)

but none the less i still love reading about these things, and i think you hould find this somewhat interesting:

MYT engine have a look around on this site, theres not as much info as i've seen elsewhere, but the basics are" 14 inches in diameter, and length, 150mpg in biodiesel, and somewhere in the vicinity of 850HP (cant remember exactly)
