FIELD: power plant engineering; engines and compressors; stationary, mobile and transport power plants of various applications. SUBSTANCE: cylinder-piston group is made in form of two-stage central symmetrical cylinder block with combination two-stage piston. Gas exchanger and gas timing system is combined with air cooling system. Engine can operate as engine and as compressor. Piston is hinge-connected by means of elongated tubular rod with end of lever of V-shaped connecting rod of accurate gear ratio transmission rectilinear guide mechanism on base of flat hinge four-member mechanism. Wall of diesel engine portion of cylinder block has air channels made in form of through longitudinal holes communicating with cylinder compressor space and with atmosphere through air cleaner. Working space of scavenging receiver communicates, through maximum pressure relay, with compressor space of cooling system and is coupled with other design members of combination heat engine. EFFECT: enlarged operating capabilities and sphere of application owing to combining working functions of main units and systems, improved power, dynamic and performance characteristics. 5 cl, 3 dwg |
