A part of the fuel carried by the near-wall flow in the piston clearance is equal to S. mixed with the air there and burned. The second (smaller) part is reflected in the direction of the toroidal recess 8. During the combustion of this portion of fuel, as well as fuel distributed along the length of the flare from the side of the piston, air is used, the amount of which is proportional to the value of the volume V. 0.2-0.26, ot, within 0.65-2, as well as wholesale, mitigating the elevation h of the height of the central conical protrusion 10 above the end surface of the collar 9, preventing the sprayer from touching the piston and ensuring the most complete displacement of air to the periphery of the chamber, allowingie to provide the best efficiency.
