CSRV Engine Technology

The Most Thermally Efficient Internal Combustion Engine Ever Developed

Revolutionary Innovation

The CSRV (Coates Spherical Rotary Valve) Engine represents a breakthrough in mechanical engineering—a fundamental reinvention of the internal combustion engine. Developed by George J. Coates, this revolutionary technology addresses the core inefficiencies of traditional poppet valve systems that have dominated engine design for over a century.

    Key Achievement: The CSRV Engine achieves unprecedented thermal efficiency through innovative spherical rotary valve technology, reducing losses and maximizing power output while minimizing emissions.
