FIELD: engines and pumps.SUBSTANCE: invention relates to ICEs. In compliance with this invention, piston has fluid-drop groove cut on piston bottom side surface some 2-3 mm from fire bottom at the angle of 22 degrees relative to piston axis, 12-13 mm in length and with spherical base of radius r = 1.5 mm.EFFECT: better compression, higher compression ratio, better combustion, lower toxicity of exhaust gases, higher engine output.4 dwg |
