Abstract

PURPOSE: Four cycle internal combustion engine which may be light and compact compared to its output.
CONSTITUTION: At upper and lower ends of the cylinder 2 are arranged the cylinder heads 7. In the piston 1 which is vertically and slidably arranged in the cylinder 2 is vertically provided the connection rod 9 passing through the central through-hole 8 in the lower cylinder head 7. The lower end of the connection rod is connected to the crank 6 via the connecting rod 5. In each of the cylinder heads 7 are arranged the intake valve 10, the exhaust valve 11 and the ignition plug 12. At both ends of the cylinder 2 are formed the combustion chambers 3, 3. In this case, both the upper combustion chamber 3 and the lower combustion chamber 3 are arranged such that the opening and closing of the intake valve 10 and the exhaust valve 11 and a high voltage application timing against the ignition plug 12 are displaced by one cycle and thereby two combustions may be provided per one cylinder during two rotations of the crank shaft 13.
