Возвратно-поступательное движение поршн 3 преобразуетс во вращение кривошипа 6 при помощи шатуна 4, т г 7 и 8 и коромысел 9 и 11. Степень сжати в двигателе измен етс путем изменени положе- ни рычага 10, качающегос в корпусе вокруг оси, проход щей через точку 16, при помощи черв чной передачи, св занной с электродвигателем 14. Так как длины рычага 10 и коромысла 9 равны, а ось качани рычага 10 проходит через точку 16, совпадающую с осью креппени шатуна 4 с коромыслом 9 при положении поршн о ММ Г, то на всех режимах регулировани степени сжати двигател положение поршн 3 относительно цилиндра 2 в будет неизменным , те. неизменным будетпопныи объем двигател , равный сумме рабочею объема и объема камеры сгорани . При изменении степени сжати будут мен ть- с лишь рабочий объем и обьем камеры сгорани . 13 двигателе с описываемой кинематической схемой при незначительном перемещении приводного звена незначительно мен етс рабочий обьем, но резко измен етс значение степени сжати , что позвол ет повысить эффективность ее регулировани и упростить приведение расчетных показателей двигател к действительным.The reciprocating movement of the piston 3 is converted into rotation of crank 6 by connecting rod 4, t 7 and 8 and rocker arms 9 and 11. The compression ratio in the engine is changed by changing the position of the lever 10 swinging in the housing around the axis passing through point 16, by means of a worm gear, connected with the electric motor 14. Since the lengths of the lever 10 and the rocker arms 9 are equal, and the swing axis of the lever 10 passes through the point 16, which coincides with the axis of the connecting rod 4 and the rocker 9 when the piston is in the MMG then in all modes of regulation of the degree of compression vigatel position of the piston 3 in the cylinder 2 will be unchanged, those. unchanged will be the engine volume equal to the sum of the working volume and volume of the combustion chamber. When changing the degree of compression, only the working volume and volume of the combustion chamber will change. 13, the engine with the described kinematic scheme, with a slight movement of the drive link, the working volume varies slightly, but the degree of compression changes dramatically, which makes it possible to increase the efficiency of its regulation and simplify the reduction of the engine's calculated values to the actual one.
