50:1 CR on pump gas - Ebadulaev Engine Cycle

[u666sa]

Not quit sure where to stick this information, this new engine cycle relies on electronics, Megasquirt is the ultimate ECU for it. Please read this information, share, and build your own prototype. This is not a spam, this is a plea. Nothing is sold, information is given to you, so you are aware of it, and hopefully research, build, and demand more powerful and fuel efficient cars from the manufacturers. Links to scientific papers and videos of working prototypes at the bottom.

Apparently this subject is 8+ years old now, and companies haven't picked up the patented work, even though working prototype engines have been constructed and shown to work. There is a new engine cycle, called Ebadulaev Engine Cycle, which allows high compression ratios (50:1 on gasoline, and 60:1 on diesel) on pump gas, without engine detonation.

Just to give you an idea, for the first prototype a 75 hp 1.6L engine was taken, these engines are about 8L/100 km efficient (29mpg), after conversion to ebadulaev cycle horsepower increased to 180 hp, and at the same time fuel economy increased to 4L/100km, or 58mpg. All this at 21:1 CR, instead of theoretically optimal 50:1.

Let's put these practical performance gains in terms of American engines, let's take a 5.0L coyote. 180hp from 1.6L is 112,5hp per liter, for a 5.0L engine it would mean 562,5 hp, theoretically, keep in mind that our original 1.6L four banger is highly restrictive, and it's head and intake only made 75 hp from the factory, so on practice we don't really know how many hp per liter will be with coyote engine. How about fuel efficiency? It should increase by 50%, so if it was 20 mpg originally, it should now be 40 mpg! Theoretically of course. Where have you seen tuning which increases at the same time power and fuel economy?

This is not a scam or spam, or dream, it is what it says it is. There are working prototypes. You don't need to buy anything, all the information is free, just research and build it. I want this information to go viral and hopefully someday we'd have fuel efficient powerful cars.

Let me try to explain how it works. In conventional 4 cycle internal combustion engine, cylinder pressure is highest at top dead center, but the power which can be transferred to the crank shaft, is achieved at it's highest peak at only 45 degrees past top dead center. This is physics, connecting rod makes a perfect pivot at 45 degrees past TDC. However, at 45 degrees past TDC pressure in combustion cylinder is more than half less that it was at the very top. This is why 4 stroke internal combustion engines are so inefficient. Ebadulaev engine cycle raises compression ratio of the engine and uses electronics to prevent detonation, in the end you get ultimate pressure at 45 degree pivot, resulting in better engine efficiency, i.e. more power and less fuel consumption.

Here is the first prototype made by Gadgi Ebadulaev himself, the man himself is driving it.

Here is another prototype made my somebody else.

This work has stalled at this point and hasn't gone past several prototypes made by individual motor heads. This is because there is virtually no car industry in Russia, even Lada we had to buy from Italians. Our best motors are descendants of the original Fiat, and they are virtually unchanged since the 70s. It is up to western companies to put this into production. I hope more people would find out about this new engine cycle.

The only problem I see is I don't understand Russian.

Also not speaking russian and just clicking through some videos, I fail to see why you call this a new "engine cycle". From what I can read you just raised the compression?
As far as I know compression ratios that high aren't commonly used primarily because the gains simply don't justify the disproportionately high wear and strain on the material.

Use google translate for the scientific paper, it will tell you more, why it is called engine cycle http://www.iga-motor.ru/raboti/1.doc

Unfortunately I know, this is all in Russian, I'm too busy right now to translate it. As far as I know, first prototype made by Mr. Ebadulaev is still working after all these years. One prototype made by another guy from Ukraine blew up because he used distributor for ignition and a carb, which you don't want to do in this application.

My Russian definitely not up to the task, however you have posted a rather long invitation to consider this item (your English seems rather good) - why don't you offer a few more facts to promote the credibility that this "unusual" concept requires.
I am particularly interested in "using electronics to prevent detonation". Isn't that what all of our efforts on these forums and utilizing the MS product has at its foundations? Seeing as how a Diesel is a "heat of compression" ignition format - how is this engine for one example - going to avoid igniting small amounts of accumulated carbon on pistons, oil naturally entering the chamber, or the aluminum bits themselves which once started would go up like a mini reactor?
But I keep a pretty open mind, not too many of us will translate those documents, why don't you offer up the Coles Notes rendition of what is at the heart of this departure from traditional internal combustion tech?

I'm skeptical, I admit, but curious and would also like to read some tech details; trying to keep that "open mind" that all novel concepts deserve.

Hi. I fail to understand how exactly the crankshft is modified in order to work in a different cycle. There are some ideas among engineers to use alternative crankshaft sytems (wobble plate, cams instead of cranks etc), but the potential gain in total efficiency is rather of a range of a few percent. Could you help me extract this information from of all this interesting stuff you have linked in your post?

+1 to the question about the knock control.

In general, if you neglect the fuel auto-ignition properties and calculate just theoretical efficiency of the otto cycle, the increase of the CR above 25-30 could not bring any significant improvement. Concerning the heat losses and mechanical efficiency, it can be only worse.
