FIELD: mechanical engineering; dual-fuel internal combustion engines. SUBSTANCE: device has control linkage, exhaust manifold and bypass member with outlet branch pipe for delivering exhaust gases into gas turbine and bypass branch pipe. Bypass member has double-acting valve for overlapping inlet hole of outlet branch pipe or bypass branch pipe. Valve is made in form of rotary gate with lever rigidly secured on valve axle and coupled with control linkage, including control member and operating mechanism. Control member consists of supply source, winding selector switch, two independent windings, core, rod and two limit switches. Rod is rigidly coupled with core. Limit switches are installed on end face covers. One lead of each winding is connected to, other leads being connected through limit switches and winding selector switch to different terminals of supply source. Operating mechanism consists of bell crank mounted onrotary axle, tie-rod, lever and locking unit. One end of bell crank is hinge-coupled with rod of control member. Second end of bell crank is hinge-coupled through tie-rod with lever rigidly secured on valve axle. EFFECT: provision of delivery of exhaust gases, when operating on liquid fuel, into bypass branch pipe and, when operating on gaseous fuel, into outlet branch pipe and further on into turbine, simplified control and improved reliability of device. 10 dwg
