Spherical Rotary Valve Diesel Engine Developed

LITTLE ROCK, Ark., March 5 -- 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.
