SUPERCHARGED INTERNAL COMBUSTION ENGINE Russian patent published in 2014 - IPC F02B67/10 F02B33/36 

FIELD: engines and pumps.

SUBSTANCE: proposed engine comprises cylinder with piston and displacement compressor. Said piston is engaged via two co-rods with two parallel crankshafts timed by two gears. Said compressor is composed of toothed compressor discs fitted on crankshafts of diameter 2r of teeth pitch circle equal to diameter DC of timing gear pitch circle. Compressor disc tooth length b is set subject to engine piston cylinder working volume, supercharge degree e and diameter DC at the following ratio $$b=e^{1/n}*R_X^2*X/\left(m*{\eta }_V*D_C\right),$$ where n is polytropic exponent of air compression in compressor, RX is the piston outer circle radius, X is piston stroke, m is the compressor disc tooth pitch, ηV is the compressor volume efficiency.

EFFECT: simplified and compact design, higher mechanical efficiency.
