ABSTRACT:
A Stirling engine having multiple cylinders arranged in a square cluster with a gas combustor devices for each cylinder integrated into the engine. The combustor devices include individual combustion chamber tubes for each of the cylinder of the engine. Air is introduced into the chambers in a manner which generates a tangential air flow which mixes with a combustible gas injected from a gas nozzle in the center of the tube which provides a highly turbulent combustible gas flow regime. Combustion gases pass through the Stirling engine heat exchangers to transfer heat to the engine. Exhaust gas heats inlet air through a counterflow heat exchanger. The relatively small size of the combustion chamber tubes enables the components of the combustion chambers to reach an equilibrium temperature repidly and minimizes thermal distortion of the components.
