FIELD: mechanical engineering; internal combustion engines. ^ SUBSTANCE: proposed internal combustion engine contains cylinder, cylinder head, piston spark plug, shaped intake with valve and exhaust channel with valve. Cylindrical projections made on piston and in cylinder head are symmetrical relative to cylinder axis and they overlap when piston is near TDC. Holes for torch ignition of lean mixture are made in projection of head. ^ EFFECT: improved antiknocking properties of engine. ^ 2 dwg |
