INTERNAL COMBUSTION ENGINE Russian patent published in 2009 - IPC F02B67/04

Abstract RU 2345231 C2

FIELD: engines and pumps.

SUBSTANCE: invention is related to propulsion engineering, in particular to internal combustion engines. Invention makes it possible to increase diameter of crankshaft support end, which in its turn makes it possible to increase diameter of flywheel fastening bolts location circumference, diameter of bolts thread and finally to provide higher capacity and torque without increase of engine dimensions and weight. Internal combustion engine comprises crankshaft, drive gear installed on crankshaft tailpiece, unit of intermediate gears, gear of power takeoff for drive of internal loads and flywheel fixed in crankshaft tailpiece by bolts. Support end of crankshaft is combined with front end of drive gear or projects from it. Ratio of flywheel fastening bolts thread screwing length to diameter of thread makes 0.6...0.9.

EFFECT: higher capacity and torque without increase of engine dimensions and weight.
