I love my Diesel engines, have several of them, father-in-law was a brilliant diesel engine mechanic.
Diesel contains more energy potential then gasoline (Diesel has more calories) it's the workhorse of liquid fuels. Compression ration is way higher in a diesel engine (~20:1 compression ratio) where the fuel/air mix is ignited solely by pressure and not a spark plug. To achieve the very high compression ratio required to ignite the diesel fuel mix you need a longer stroke to achieve the higher pressure, long stroke engines inherently have bigger heavier crank throws and all that results in crazy high torque specs relative to a gasoline engine. Diesel is more dense and burns slower then light fuels, so a long stroke is ideally suited to getting the most energy possible out of the fuel.
