Abstract

A method of automatic control of the load of naval engines, in which engine speed is controlled, by means affecting the supply of] fuel to the engine or engines, and in which the positions of the fuel pump are detected and They compare with predetermined limit values, such that when: these limit values are exceeded, a signal is transmitted; corrector in the form of a pulse train to a servo system that acts to adjust the pitch of the ship's propeller or propellers in a staggered manner, with one step of adjustment for each pulse of the pulse train, where, when widely exceeded At said limit values the correction signal is first transmitted directly to the servo system, as a continuous signal, so that an adjustment of the continuous step is then carried out, the correction signal being made again as a pulse train when the limit values are very close.
