Laterally-arranged oil supply double-wall-collision flow guide type oil-gas mixing system

The invention discloses a laterally-arranged oil supply double-wall-collision flow guide type oil-gas mixing system. The system is suitable for an opposed piston engine. A combustion chamber adopts adeep pit type combustion chamber, and a guide arc is arranged on the peripheral wall surface in front of a combustion chamber deep pit and on the oil supply side of the combustion chamber; the guide arc serves as a lateral wall surface oil beam wall attachment point, and the hole diameter of a multi-hole oil sprayer is designed so as to ensure that the splitting length of oil beams sprayed out ofthe oil spraying holes is larger than the distance from the oil spraying holes to the lateral wall surface oil beam wall attachment point, so that sprayed fuel oil firstly collides with the guide arcto form wall surface jet flow stripping and then deflects towards the center of the combustion chamber deep pit; the fuel oil mainly exists in a liquid state before collision; and a flow guide pit isformed in the side, away fro
