Company Coates International Ltd Other OTC

Coates International, Ltd. is engaged in developing the Coates Spherical Rotary Valve (CSRV) system technology, which is adaptable for use in piston-driven internal combustion engines of various types. The Company's CSRV Engines produce only ultra-low levels of harmful emissions while in operation. Engines operating on the CSRV system technology can be powered by a selection of fuels. The CSRV system is designed to replace the intake and exhaust conventional poppet valves used in almost all piston-driven stationary, automotive, motorcycle and marine engines. Unlike conventional valves, which protrude into the engine combustion chamber, the Coates rotary valve system utilizes spherical valves that rotate in a cavity formed between an over two-piece cylinder head. The Coates rotary valve system uses approximately 1/10th the moving parts of conventional poppet valve assemblies. The Company has adapted its technology to industrial engines to power electric generators.
