ABSTRACT:
A heat regenerative external combustion engine is disclosed herein. The ene includes fuel inlet means which extends along the exhaust passage and/or combustion chamber in order to preheat the fuel. To provide for preheating by gases in both the combustion chamber and the exhaust passage, the combustion chamber is arranged annularly around the drive shaft and between the cylinders. This configuration also is advantageous in that it reduces the noise of combustion. The engine of the invention is particularly well-suited for use in a torpedo.
