Combustion chamber structure

The utility model discloses a combustion chamber structure which comprises a cylinder body, a cylinder cover is arranged on the top of the cylinder body, and a plurality of flow guide grooves are formed in the top of the cylinder cover. An air inlet pipe is welded at the diversion trench of the cylinder cover; a bulge is arranged at the welding part of the air inlet pipe and the diversion trench; the piston is arranged in the cylinder body in a sliding mode, the protrusion arranged at the bottom of the air inlet pipe is matched with the flow guide groove in the cylinder cover, air flow entering the cylinder is guided, concentrated and powerful air flow is formed, and therefore the tumble ratio and the turbulence energy are improved; the shape of the top face of the piston is optimized, in the compression process, airflow is guided to do circular motion, tumble forming is promoted, and the combustion efficiency is improved. 本实用新型公开了一种燃烧室结构，包括缸体，缸体顶部设有缸盖，所述缸盖顶部设有多个导流槽；缸盖在导流槽处焊接有进气管，进气管与导流槽的焊接处具有凸起；缸体内滑动设置有活塞，通过
