COMBINED POWER UNIT WITH DOUBLE CRANKSHAFT Russian patent published in 2023 - IPC F02B33/22 F02B37/00 F02B41/06 F02B75/02 F02G3/02 F02G5/02 

FIELD: mechanical engineering.

SUBSTANCE: invention relates in particular to power plants operating in conjunction with an internal combustion engine. The proposed combined power plant system includes turbocharger 1 and a combined engine consisting of working part 3, pneumatic part 4 and compressor part 5. Each of the parts has a cylinder-piston group (CPG), as well as a cylinder block head (CBH) with an intake and exhaust manifold system, with a valve mechanism. Pneumatic part 4 and compressor part 5 are connected by common first crankshaft 6. Working part 3 includes a second crankshaft, at the output of which second gear 12 is installed, connected by rigid gear 13 with the first gear 11 installed at the output of the first crankshaft 6. At the same time, the outlet of turbocharger 1, which pumps air through the pipeline, is connected to the inlet of compressor part 5, and the outlet of compressor part 5 is connected to the inlet of working part 3. The inlet of working part 3, containing the exhaust gases, is connected to the inlet of pneumatic part 4, and the output of pneumatic part 4 is connected to the inlet of turbocharger 1.

EFFECT: increased efficiency of the system, increased efficiency using exhaust gas energy with a simple design and compact placement of assemblies.
