Abstract
An internal combustion engine includes an insulated combustion chamber having a fuel mixture inlet and a spark plug nearby the inlet. A series of baffles is configured within the combustion chamber to absorb a shockwave caused by ignition of fuel mixture by the spark plug. A turbine receives reduced-pressure combustion gases from an exhaust-side of the baffles and there is a power takeoff at the turbine.
