  • Patent number: 6988358
    Abstract: Provided is an engine having positive displacement chambers containing pistons and an external combustion chamber which utilizes the compression energy in compressed natural gas from a high pressure main line and compressed air in combination with the energy released during combustion of the fuel to drive the pistons. Energy expended compressing the natural gas and air are recovered. Also provided is an electrical generator driven by the engine.
    Type: Grant
    Filed: March 4, 2004
