  • Linear fluid engine
    Patent number: 7261070
    Abstract: A linear fluid engine includes a power transfer cylinder that is driven by combustion of fuel in a combustion cylinder to pressurize a power transferring fluid. Some of the power transferring fluid is used to power a subsequent compression stroke in the combustion cylinder and, optionally, the intake/exhaust valves on the cylinder. A controller controls the compression stroke and intake/exhaust valve operation based on a stored control algorithm.
