<p>The engine has two piston systems preferably working in counter stroke from a common crankshaft. A complementary heat exchanger absorbs heat from one piston system via a change over valve, a by pass and a cooler. The size of the heat exchanger is dependent upon the temp. difference between both sides of the heat exchanger. The heater construction depends upon the fuel type and the cooling is achieved by slip stream. The system could also be used with engines working on the Stirling principal and using a Rhomben gear.</p> |
