If I remember correctly, some to the military aircraft of WWII used
water injection. There was a mode in which maximum demand was made on
the engine, and it was necessary to add water injection to prevent the
engine from explodeing under the pressure. Evidently the water cooled
the fuel air charge sufficiently to prevent the engine from flying apart
under such a load, known back then as "Military Power".
