FIELD: mechanical engineering; engine shaft speed governors. SUBSTANCE: proposed diesel-generator is designed for use as ac source with provision of three nominal operating duties. Levers 8,10 of control mechanism are connected by tie-rods 11, 12, 21 and 23 with generator pole selector mechanism 14, articulated lever rotation mechanism 3 and control lever 15 of turbocompressor bypass valve 16. Bypass valve 16 is installed between intake and outlet branch pipes of turbocompressor. Control mechanism has three degrees of freedom. EFFECT: increased efficiency of overcoming peak loads, reduced materials usage and cost of power-generating plant. 2 cl, 2 dwg
