Изобретение относится к области двигателестроения. а более конкретно - к усовершенствованию конструкции поршня, направлено на улучшение виброакустических характеристик ДВС и других поршневых машин. Усовершенствование конструкции предлагаемого поршня заключается в том, что поршень снабжен специальной неметаллической или композиционной полимерной вставкой, выполненной в виде цилиндра с эксцентричным отверстием под поршневой палец, установленной в предварительно увеличенные отверстия бобышек поршня вместо поршневого пальца. Указанная вставка многофункциональна, т.к. обеспечивает не только дезаксаж поршневого пальца, но и смещение центра масс поршня относительно продольной оси, уменьшение массы поршня и демпфирование вибрации. Благодаря многофункциональности вставки при работе двигателя происходит существенное улучшение виброакустических характеристик.The invention relates to the field of engine manufacturing. and more specifically, to improve the design of the piston, aimed at improving the vibro-acoustic characteristics of ICE and other piston machines. The improvement of the design of the proposed piston consists in the fact that the piston is equipped with a special non-metallic or composite polymer insert made in the form of a cylinder with an eccentric hole for the piston pin installed in the pre-enlarged holes of the piston bosses instead of the piston pin. The specified insert is multifunctional, because It provides not only decontamination of the piston pin, but also displacement of the center of mass of the piston relative to the longitudinal axis, reduction of the mass of the piston and vibration damping. Due to the versatility of the insert during the operation of the engine, there is a significant improvement in vibro-acoustic characteristics.
