Abstract

Изобретение относитс  к области машиностроени , в частности к шатунно-поршневым группам двигателей внутреннего сгорани . Целью изобретени   вл етс  повышение КПД и расширение фазы газораспределени  путем обеспечени  задержки поршн  в верхней и нижней мертвых точках независимо от вращени  вала. Устройство содержит приводной вал 1 и шатун 2, шарнирно св занный с поршнем 3, на котором установлен эксцентрик 4 с поводком 5, взаимодействующим через т гу 7 с кронштейном 6, установленным на шатуне 2. При вращении приводного вала 1 за счет смещени  осей эксцентрика 4 и шатуна 2 происходит задержка поршн  3 в верхней и нижней мертвых точках, что позвол ет расширить фазу газораспределени  и повысить КПД. 3 ил.The invention relates to the field of engineering, in particular to the connecting rod-piston groups of internal combustion engines. The aim of the invention is to increase the efficiency and expansion of the camshaft phase by providing a delay of the piston at the upper and lower dead points, regardless of the rotation of the shaft. The device contains a drive shaft 1 and a connecting rod 2, pivotally connected to a piston 3, on which an eccentric 4 is installed with a driver 5, which interacts through a pull 7 with a bracket 6 mounted on a connecting rod 2. When the drive shaft 1 rotates due to the displacement of the eccentric 4 axes and the connecting rod 2, the piston 3 is delayed at the upper and lower dead points, which makes it possible to expand the gas distribution phase and increase the efficiency. 3 il.
