Abstract: Изобретение позволяет повысить удельные мощностные и габаритные характеристики двигателя внутреннего сгорания (ДВС). ДВС выполнен с лопастным ротором, содержащим два полых цилиндрических вала, установленных соосно один в другом, при этом внутренний вал жестко связан с парой диаметрально расположенных лопастей, а внешний вал выполнен сборно-разборным и состоит из пары полувалов с фланцами и пары сдвоенных ведущих лопастей, соединенных по торцам с фланцами полувалов разъемными устройствами. Внутрь ведомого вала помещена цилиндрическая втулка, жестко скрепленная со статором двигателя, на основе которой в ДВС выполнена система газораспределения в виде двух групп отверстий, расположенных на полой цилиндрической втулке и на внутреннем валу в зоне камер сгорания. Полость цилиндрической втулки разделена осепоперечной перегородкой на канал подачи рабочей смеси и канал выпуска отработавших газов. Между ведущими и ведомыми лопастями образуются переменные объемы (камеры сгорания). Ведущие сдвоенные лопасти и ведущий вал вращаются в статоре вокруг его центральной оси, а ведомые лопасти - вокруг центральной оси статора и одновременно совершают колебательные движения относительно сдвоенных лопастей. Синхронизация работы валов и их лопастей обеспечивается кулисно-рычажным механизмом. При вращении ведущего вала с лопастями рычаг и оси подвижных шестерен перемещаются вокруг центральной оси двигателя. При этом подвижные шестерни, обкатываясь по неподвижной шестерне, вращаются вокруг своих осей. Круговые движения кривошипов вокруг осей через ползуны и кулису передаются ведомому валу с ведомыми лопастями. 5 ил.
