Claims (1)

Двигатель внутреннего сгорания с регулированием степени сжатия состоящий из вспомогательного поршня, пружины, системы гидравлического управления перемещением вспомогательного поршня в зависимости от нагрузки двигателя, отличающийся тем, что он дополнительно снабжен вставкой, а во вспомогательном поршне выполнено отверстие для форсунки, при этом вставка и поршень совместно образуют две масляные полости, пружина установлена в нижней полости, а верхняя сообщается с системой смазывания двигателя, причем полости сообщаются между собой через прямой и обратный клапаны и образуют в совокупности систему гидравлического управления перемещением вспомогательного поршня в зависимости от давления газов в цилиндре двигателя.An internal combustion engine with compression ratio control consisting of an auxiliary piston, a spring, a hydraulic control system for moving the auxiliary piston depending on the engine load, characterized in that it is additionally equipped with an insert, and an opening for the nozzle is made in the auxiliary piston, while the insert and piston are combined form two oil cavities, the spring is installed in the lower cavity, and the upper communicates with the engine lubrication system, and the cavities communicate with each other h Through direct and non-return valves, they together form a hydraulic control system for the movement of the auxiliary piston, depending on the gas pressure in the engine cylinder.
