Abstract
Цилиндропоршневая группа двигателя внутреннего сгорания, содержащая цилиндр и поршень, в поршневой канавке которого установлено компрессионное кольцо с конусной рабочей поверхностью, отличающаяся тем, что внутренняя поверхность цилиндра выполнена в виде усеченного конуса с большим основанием в нижней части цилиндра и с меньшим основанием в верхней части цилиндра, а рабочая поверхность компрессионного кольца выполнена в виде конуса с уклоном к своему верхнему торцу, причем угол конуса рабочей поверхности кольца αк меньше угла конуса цилиндра αц на величину его изменения в результате термодинамических изменений размеров цилиндра в процессе работы двигателя.A cylinder-piston group of an internal combustion engine comprising a cylinder and a piston, in the piston groove of which there is a compression ring with a conical working surface, characterized in that the inner surface of the cylinder is made in the form of a truncated cone with a large base in the lower part of the cylinder and with a smaller base in the upper part of the cylinder and the working surface of the compression ring is made in the form of a cone with a slope to its upper end, and the cone angle of the working surface of the ring αk is less than the cone angle ilindra αts the amount of change as a result of thermodynamic changes sizes of the cylinder during engine operation.
