This is a utility patent application for the design of a large marine engine that is also suitable, in different configurations, for smaller marine applications and many different power generation and transportation applications. The drawings show a ten-cylinder two-stroke engine, cylinders with a 110-inch stroke and 36-inch bore, pistons, connecting rods, and a crankshaft. The pistons are driven by the combustion of liquid hydrogen and liquid oxygen ignited by a sparking system. The engine is cooled via coolant passages in the block and head and lubricated by three separate lubrication systems. It uses cryogenic fuel pumps, electronic fuel injection, and electronic actuators regulated by a remote engine control unit. It is close to a zero emissions design, with only steam, water vapor, and extremely minute quantities of burned lubricants and trace air combustion products heading up the stack.
