TWO-STROKE INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: engine has crankcase 1 with by- passing passage 2 and inlet port 2, cylinder 4 with blowing ports 5 and piston 6 positioned inside it, above- piston space 7, head 8 of cylinder 4 provided with spark plug 9, crankshaft 10 set in two bearings 11, connecting rod 12 with a plate positioned in under-piston space 13, flange 14 with connecting pipe 15 for supplying fuel, passage 16 of flange 14, and locator 17 which provides a space between flange 14 and connecting rod 12 with the plate. When crankshaft 10 rotates, piston 6 moves forward. When piston 6 moves upward, rarefication occurs in under-piston space 13 and fuel mixture enters space 13 through passage 16. When piston 6 moves back, connecting rod 12 overlaps passage 16 and mixture enters cylinder 4. EFFECT: enhanced efficiency. 8 dwg
