Abstract
Двигатель внутреннего сгорания, содержащий блок цилиндров, чугунную втулку цилиндра, чугунную крышку цилиндра, стальную прокладку газового стыка между втулкой и крышкой цилиндра, скрепленные при помощи силовых шпилек крепления цилиндрового комплекта к блоку цилиндров, отличающийся тем, что с целью повышения эффективности уплотнения газового стыка камеры сгорания между втулкой цилиндра и крышкой цилиндра прокладка газового стыка выполнена прямоугольного сечения, толщина которой соизмерима с шириной, из материала, твердость которого ниже твердости сопрягаемых втулки цилиндра и крышки цилиндра на 10÷15%, и размерами, обеспечивающими напряжения сжатия в прокладке от усилия затяжки силовых шпилек крепления цилиндрового комплекта ниже предела текучести материала прокладки на 15÷20%, а на поверхностях газового стыка втулки цилиндра и крышки цилиндра выполнены выступающие зубчики треугольного сечения, шириной и высотой составляющие 2÷5% от ширины прокладки газового стыка и располагающиеся в средней по ширине зоне прокладки.An internal combustion engine comprising a cylinder block, a cast iron cylinder sleeve, a cast iron cylinder cover, a steel gasket of a gas joint between the sleeve and the cylinder cover, fastened with power studs to secure the cylinder kit to the cylinder block, characterized in that in order to increase the sealing efficiency of the gas joint of the chamber of combustion between the cylinder bushing and the cylinder cover, the gas joint gasket is made in a rectangular section, the thickness of which is commensurate with the width, from a material whose hardness the hardness of the mating cylinder liner and cylinder cover by 10 ÷ 15%, and dimensions that provide compressive stresses in the gasket from the tightening force of the power studs of the cylinder kit below the yield strength of the gasket material by 15 ÷ 20%, and on the surfaces of the gas joint of the cylinder bushing and the cover protruding teeth of triangular section are made of the cylinder, with a width and height of 2 ÷ 5% of the width of the gas joint strip and located in the middle width of the gasket zone.
