Wood gas and the preparation of diesel fuel

Did World War II navies seriously consider wood gas as warship fuel?

They examined it without adopting it for warships; even flexible diesel engines still needed suitable fuel preparation.

Wood gas was examined as a wartime warship fuel, but navies did not take the idea into use. Admiral Graf Spee illustrates the preparation still required for diesel fuel. Its supplied crude oil had to be degassed before it could be used in the engines. A diesel engine's ability to accept different fuels still depends on making each fuel suitable for the machinery.
