Coates International, Ltd. Has Been Contacted by Certain People, Entities and Institutions to Explain How the Company Can Claim That the Coates CSRV Patented Internal Combustion Engine Is the Most Advanced in the World

WALL TOWNSHIP, NJ--(Marketwired - Jul 9, 2015) - Coates International, Ltd. (OTC PINK: COTE) (the "Company") Directors asked Company President and CEO, Mr. George J. Coates, to respond.


The poppet valve engine has been around for more than 100 years and the poppet valves, camshafts, cam followers, rockers, tappets, and push rods are the biggest problems in the design of the poppet valve internal combustion engine. Manufacturers have tried everything to make the poppet valve engine more efficient adding more poppet valves, overhead camshafts, turbo chargers, and super chargers. All of these attempts have made very little improvements that will never meet with new regulations, EPA and carbon reduction world standards, it will be quite impossible to create a poppet valve engine that will meet the new required standards of internal combustion engine thermal efficiencies.

On the other hand, here at Coates International, Ltd. we have designed the most advanced CSRV internal combustion engine in the world. We claim this because of the following:

1. In a N.14 or 855 Cummins industrial engine, we eliminate 2,700 parts and components out of that engine.

2. Eliminate the oil pressure supply to the head of the engine and only utilize the engine oil pressure for the cranks shaft bearing supply to the lower half of the cylinders.

3. We replace all 2,700 parts with only two assembly CSRV rotating shafts and two floating seals for each cylinder.

4. Greater volumetric efficiency up to double that of the poppet valve has been achieved.

5. Utilizing higher compression ratios of 12 to 1 and up to 20 to 1. Poppet valve engines in vehicles using gasoline are approximately 11 to 1, Caterpillar, Cummins 8.5 to 1 operating on natural gas and only operate as stand by emergency systems and not constant operating service.

6. The Coates CSRV engines have been independently tested and have proven results with more (H.P.), higher (R.P.M.s), lower fuel consumption, higher thermal efficiencies while producing lower harmful emissions released into our atmosphere.

7. The Coates CSRV engines operate on natural gas, CNG, LNG, propane, hydrogen, gasoline, diesel, and a combination of these fuels.

8. Poppet valves cannot operate higher than 8.5 to 1 compression ratio operating on LNG, CNG because the poppet valves are constantly in the combustion chamber and get red hot, when the constant temperature of the combustion chamber exceeds 2,400° F when it does, it manufactures No X. (oxides of nitrogen) and Co. (carbon monoxide) and uses much more fuel the engine thermal efficiency is reduced. The governments around the world are asking the impossible of the poppet engine.

9. The Coates CSRV Spherical Rotary Valve System constantly rotates away from the combustion chamber heat using incoming air to cool the inlet and cooling the exhaust with a water cooling system through the center of the exhaust assembly shaft; 35 gallons of water per minute.

10. There is no servicing or adjusting or maintenance to the CSRV system for the life of the engine.

11. Engine oil changes are extended to 50,000 miles or more.

12. The reason poppet valve engines do not last operating on natural gas; this fuel does not have any lubricating properties contained in it. As a result, number 1. piston rings in poppet valve engines wear out in a very short time.

13. The Coates CSRV engines incorporate the patented Coates sequential fuel injection system that injects a minute amount of diesel fuel in with the natural gas that the engine operates on. This prevents excessive wear on number one piston rings.

  • Incorporating higher compression ratios
  • Incorporating greater volumetric efficiencies
  • Less moving parts
  • Utilizing a stoic metric mixture throughout the acceleration curve creates the highest thermal efficient internal combustion engine

All this technology was invented and designed by Mr. George J. Coates and his son, Gregory G. Coates, over more than 20 years. Many patents have been awarded from the USA and from most industrial countries around the world.

All of the above technology and design is the reason that we call this CSRV engine ((the most advanced internal combustion engine in the world.)) There is nothing out there that compares.

I hope this answers all of the questions that we have been receiving.

There can be no assurance that the Company will be successful in any of its endeavors.
