\"DIESEL ENGINES: Four main Fairbanks-Morse 10-cylinder opposed piston 38D - 8 & 1/8\" two-cycle diesel engines. Opposed piston engines have two pistons arranged in opposite positions in each cylinder connected to crank shafts at the top and bottom of the engine. As the pistons travel toward each other they compress the air between them. At their closest point the space becomes a combustion chamber as fuel is injected. The resultant expansion caused by combustion pushes the pistons apart which causes the crank shafts to rotate. The upper and lower crank shafts are connected by a vertical drive gear. The main engines produced 1,600 horsepower at 720 rpm, and 1,280 at 650 rpm.\"
These were the better engines used in the US boats. At the start of the war, a number of boats were built with a US built variant of the German M.A.N. engines, which were given the unfortunate acronym, H.O.R. The boats were, of course, known as HOR boats. (For the non-English, HOR would be pronounced as Whore\" The HOR engines were a disaster and all boats had the engines changed during the war.
2-cycle engines do not necessarily use more fuel. Cummings has made popular 2-cycle, super-charged truck engines for decades.
