65 MPG Split Cycle Engine the Next Big Thing?

04/06/2012 1:45 PM

http://www.greencarreports.com/news/1074840_65-mpg-split-cycle-the-next-direction-for-gasoline-engines#comment-10001281 Is this something really new? What are the chances of it catching on? Does it make sense to you? Is it cost effective? Is it limited to small vehicles?

Well a turbocharged 4 cyl that get 65mpg, The diesels already get better than that, I think...Really need more facts...Here's a 1.5 lt rated at 74 mpg...

http://www.nextgreencar.com/view-car/12784/SEAT-Ibiza-Diesel-Manual-5-speed

Here's a whole list starting at 86mpg...

But of course this is only half the equation, the costs associated with the vehicle must be considered...The amount of power being produced is good comparison....

This Scuderi design has been illustrated on YouTube for some years now. It is one of hundreds (perhaps thousands) of modifications to the basic Otto Cycle engine that looks so promising, yet has failed, so far, to make it into production. Mazda brought us the Miller Cycle engine in the Millenia 20 years ago, yet where is it now? There have been dozens of clever rotary designs and scavenged 2-strokes, including those of Ralph Sarich. He became a millionaire selling his patents to nearly all the major engine manufacturers, yet no-one followed through.

The big question is: why not? The usual reason given is that the improvements were not regarded as worth the capital investment required. No doubt also that many were put off by the Wankel Rotary Engine fiasco, which bankrupted NSU. Motor manufacturers are a very conservative lot and, like airlines, many are never far from bankruptcy.

What we need is a billionaire entrepreneur to put up the money to fund a new engine for motor vehicles. When I see how Apple were sitting on $70 billion in cash a year ago (probably even more now), I have to wonder why they, (or Gates, Buffet, Trump, Turner etc.) don't try and do something for useful with their money. Too busy rolling around in it perhaps.

It is very possible that all proven or patented improvements that supposed to enhance and maximize MPG engines performance were all bought outright, kept in vaults for safe keeping by those rich people who have heavily vested interests in oil productions and other by products!

That is OLD technology. That they have some gimmick to apply for a Patent over is irrelavent.

There is NOTHING new in automotive, its the most over-engineered field there is.

The 1985 Chevy Chevette diesel got 65 mpg highway.

The only thing needed to get higher mileage is higher compression.

"Atkinson cycles extract more energy from combustion, but produce less power."

Means less efficiency, when more energy is rejected in heat.

Another warmed over, old idea looking for funding.

And the Big Lie (every scam has one, people who dont understand Physics fall for them)

"Essentially, the engine can do more work per crankshaft revolution. The paired cylinders work as a team, rather than every man for himself."

Two cylinders have more loss than one. Less fuel is required to move TWO cylinders which costs efficiency.

All this is is a hidden supercharger.

PS, this is nothing but a warmed over "pre-combustion chamber" from the 19TWENTIES, which was designed due to spark plug problems
