Abstract
A cylinder gas recirculation system device of an internal combustion engine based on pressure differential driving is provided, the overall device includes a recirculation intake and exhaust system and a gas storage system. An intake control valve on a cylinder block, a surge tank, and an exhaust control valve on the cylinder block are sequentially connected to form a gas recirculation subsystem of the cylinder block of the internal combustion engine. Two adjacent subsystems are in communication through an intake pipe. Positions of intake and exhaust pipelines may be anywhere between the top and bottom dead centers of a piston in a cylinder, and intake and exhaust valves of the gas recirculation may share the same valve. Different valves may also be used, and the intake and exhaust pipelines of the gas recirculation are arranged on the same side of the cylinder in double layers.
