Abstract

The invention relates to the design of combustion chambers and allows an increase in engine power by increasing the burning rate of the fuel. The main combustion chamber is communicated via a nozzle with a vortex combustion chamber and is limited to the surfaces of the cylinder, its head and the bottom of the piston. The central cavity (CV) 7 is diametrically placed in the bottom of the core, adjacent to the nozzle at one end and made with a cylindrical generatrix. The depth of CV 7 decreases at both ends. CV 7 communicates with two curved grooves 11 and 12, located on both sides of it. At the bottom of the piston, a buffer cavity 13 is made in the zone of max. removed 1 and from the nozzle and two cavities 14 and 15, symmetrically placed about the axis 16, CV 7, tapering in the direction of the nozzle and adjacent to it. The notches 11 and 12 are located under the valves at a depth of lesser depth CV 7, and communicate with each other at the same depth with cavity 13 and two symmetric cavities 14 and 15. Zones 17 and 18 of cavity 13 and cavities 14 and 15 are made with a depth that decreases in the direction of the periphery of the piston head. CV 7 is made from the side of the nozzle with a width equal to the diameter of the nozzle. Bottom m. B. made of heat insulating material and secured to the floor using a dovetail type joint. Such an embodiment of the engine leads to the most complete use of air by creating vortex and turbulent flows in the overgrown space, reducing the burning period of unburned fuel in the vortex combustor and ensuring the fuel burns out when the engine is forced up near the top dead center. 2 3. p.
