Title:
OPPOSED-PISTON INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2023/238418
Kind Code:
A1
Abstract:
Provided is an opposed-piston system, in which an intake compression cylinder (1) and an expansion exhaust cylinder (2) are individually provided, and a rotating perforated columnar valve (3) and an ignition combustion chamber (4) are formed therebetween. A valve mechanism is disposed on the cylinder side-surface side. A disc cam (7) moving in tandem with the rotation of the crank actuates an intake valve (33) and an exhaust valve (34) at the cylinder side-surface through a movable fulcrum type rocker arm (8). The movable structure of the rocker arm also sets the opening/closing amount of the intake valve (33) and the exhaust valve (34), such amount matching the operational state of the engine. Two connecting rods can be easily connected to one piston because a piston pin (18) and a piston pin (30) absorb the variations in the engine occurring when the two connecting rods are connected to the one piston.
