The utility model discloses an internal combustion engine system. Particularly, an opposed piston engine is provided with a plurality of air inlets surrounding the wall of a cylinder. The internal combustion energy system aims at obtaining fluid with high swirl rate through the minimum pressure drop. The internal combustion energy system is provided with air collecting chambers which are roughly spiral, and the central line of each spiral air collecting chambers spins toward the inside. Further, the area of cross sections of the spiral air collecting chambers is reduced in the flowing direction. The area is reduced with the fluid entering the air inlets from the air collecting chambers, and accordingly, the speed of the fluid in the air collecting chambers cannot be reduced abruptly when the fluid approaches the downstream end. An air inlet system is provided with a plurality of spiral air collecting systems which are connected with a plurality of groups of air inlets which are not communicated with each other. High swirl rate can be generated due to the spiral shape, and flowing energy can be reduced limitedly.
