SYSTEM FOR CONTROLLING INTERNAL COMBUSTION ENGINE POWER Russian patent published in 1994 - IPC

FIELD: engine engineering. SUBSTANCE: system has piston compressor 3 coupled to space of crankcase 4 by compression space 5 through check valve 6 positioned within a piston of compressor 3, control lever 10 kinematically connected with centrifugal controller 9, valve 11 for fuel supply set in pipe line 1 for supplying fuel, and crankcase fluid pressure valve 7. Valve 1 and valve 7 are located in the same plane and are in contact with each other through a body of lever 10. When a load on the engine is changed centrifugal controller 9 displaces control lever 10 which ether increases flowing section of valve 11 for fuel supply and tightening of a spring of valve 7 resulting in increasing pressure in the chamber or decreases both fuel supply and pressure of fluid in crankcase by discharging it through a drain opening of the valve. EFFECT: enhanced reliability. 1 dwg
