LITTLE ROCK, Ark., March 5 /PRNewswire/ -- Jeff England, CEO of McLean, England & Associates, LLC of Little Rock, Arkansas states, We believe the spherical rotary valve combustion engine will be the 'bridge' technology that will take this country and the rest of the world from the inherently inefficient tappet valve engines we drive today to the hydrogen combustion and fuel cell engines of the future.
McLean, England & Associates, LLC owns the Exclusive License for the Coates Spherical Rotary Valve Technology for North America. Their license covers Trucks in Classes 2C through 8, Motor Homes and Buses. Any motor vehicle weighing over 8,000 pounds intended for use on public roads is included in their license. George Coates, President of Coates International, Ltd., the inventor, started this diesel engine on February 26, 2003. This is the first time since Rudolf Diesel invented the diesel engine over 110 years ago that a piston diesel engine has run without the assistance of a cam driven tappet valve train.
The Coates Spherical Rotary Valve (CSRV) engine has only two moving parts in its head compared to over 100 moving parts in a conventional tappet valve head. Their head can be retrofitted to any existing engine block.
There are twelve (12) patents issued with respect to this technology. There are five (5) additional patents pending. Preliminary tests indicate an increase in fuel efficiency, higher horsepower, and lower emissions with less service and maintenance requirements because the head operates lubrication free. This eliminates the need to change engine oil because it's not contaminated by the combustion process, states Mr. England.
A nationally recognized independent lab located in San Antonio, Texas will perform the EPA emission certification tests early this summer. We plan to make this technology available to all engine manufacturers once certified.

YEAA AND A 300 SHOT OF nawwwssss...LOL

ACTUALLY WOW..cool

 

Wow, is that thing actually as big as it looks in the pic?!

 

I remember reading something about this around a year ago. I wonder if this will have any impact on engine construction for the big auto makers.

 

Yeah, I read about this too. They bolted their head unto a ford 302 and it made 75% more HP. It's like taking the valve out of the port completly and slamming it back in. Also the path for the air to flow is so much better. It is very interesting!

the 302 thing sounds farmiliar...hmmm..I remeber something about it...and was like WOW...you think this is the valve and camless engine GM was working on?? or possibly working with him to do??
75% more power thats alot..almost doubled it..anywho..

sounds really interesting..

 

Who ever said the internal combustion engine's days were numbered? With technology like this, it will be around for awhile longer at least. Considering how inefficient modern IC engines are, its not surprising that technology has made the leaps and bounds that it has in the last 20 years. Very interesting indeed.

 

I just don't know how they seal those things off...

Asuming they could seal it and it were reliable, what if you combined all the latest technologies:

Variable Valve Timing
DOD
Direct Fuel Injection
CVT

How efficient could you make it?

 

They had a story on that in the Chicago Tribune just the other day..I thought it was interesting then too..and it showed a pic on how it will work...intriguing

 

ya it siounds awesome, I remember the article, with the 302, that company (maybe this one) has stopped working on regular engines, and sticks to something else. I wanted those heads very badly, but they were priced around 10-12,000 dollars. Which isn't worth the price, I could build a blown engine for cheaper that would push more power. If it were just slightly cheaper they could have sold so many of them, but instead were all given the shaft! Oh well maybe someday soon

 

so is this right, instead of a valve there is a hollowed out ball that trurns, instead of a valve?, i am sure it could work, but wouldn't the seem become an issue? even though i am sure that the power would more then compensate for a leak, also wouldn't this allow for like a 10k plus rpm range? like i said before it seems rational, (i didn't say that before)...anyways, i could of thought of this!!!!! where is all the genius for the automotive industry, i thought people got rich doing this

"I just don't know how they seal those things off...

Its a patented process, If the Automakers knew, they would have developed this technology a long time ago as well.

"Asuming they could seal it and it were reliable, what if you combined all the latest technologies:"

It can be sealed (obviously, it works on a high PSI diesel) and its much more than reliable. Think: NEVER dropping a valve or any part in the valvetrain in any circumstance/race.



"Variable Valve Timing "- No need to vary valve as the enherent varrying in valve lift is in response to a cyl heads inability to fill the combustion chamber in response to RPM of the engine. THis technology will definitely fill the chamber to the Nth rpm.

"DOD-" I am not sure of this point right now as the technology is new and Gm's DOD utilizes a valve that slips into place and prevents the cyl from firing etc... However, i don't see how it couldn't be implemented.

"Direct Fuel Injection-" DEFINETELY..

"CVT-" ??? WHat is this abbrev? Constant velocity transmission?

"How efficient could you make it?"

Enherently the COATES SRV is much more efficient as a standard pushrod motor. think upwards of 30+% alonewithout any other mentioned technology's
The elimination of valvetrain components (read friction) frees up alot of HP, a sealed cylinder head ( means no oil into the combustion chamber), the allowance of higher Compression ratios without detonation etc..
Foremost is the fact that it is sooo Clean burning that it doesn't necessitate the use of catalytic converters..freeing up another 20+ hp dependant upon the engine.


Is it the future of the internal combustion engine?
MORE THAN YOU KNOW.

The thing I don't understand is why isn't this used? These coates heads have been around for 10 years. If it were so great with no tradeoffs, they'd be in use now...

There must be a catch...

 

Continuously Variable Transmission. The gears of the transmission change tall to low in any amount necessary by the engine. This eliminates the need for shifting any gears. Imagine accelerating with a high performance CVT. You mash the gas and right when you get traction, the gearing instantly goes to your horsepower peak at 6000 rpms and as you accelerate, it stays there at 6000rpm's the entire time while the gear ratios continuously change to smaller ratios on a continuous intreval. Great for high performance in that you will always accelerate with your greatest power output. It will save gas in that you can accelerate with the RPM's always at a minimal amount at nearly idle. This transmission is the way of the future.

 

The only catch that I can think of is that the heads are patented and the manufacturer is asking a high price for the set, area of what, $10,000 up? Now if any auto manufacturer wanted to use them think of the higher cost since a regular head costs what, wild guess of $500. Now if you were an auto maker wouldn't you rather wait till the patent runs out or the heads get in the price range of a regular head and then use them not slapping the extra $10,000 on a car? Think you would pay about $25k for a freakin sunfire. $19K if not more for a Kia Spectra, common, that would be ridiculous.
