Abstract

Изобретение позвол ет снизить механическую напр женность двигател  путем уменьшени  динамики цикла, а также теплонапр женность дополнительной камеры сгорани  (КС). В цилиндр через КС 4 при помощи впускного клапана 10 с фазами работы, совпадающими с фазами работы впускного клапапроизвод т подачу дополнительна 1 1 него воздуха, сжатого до давлени , превьшающего давление сжатого воздуха , подаваемого в цилиндр через клапан 11, При поступлении воздуха в КС 4, а затем в цилиндр через канал 7 клапана 10 при открытых клапанах 6 и 10 через форсунку 5 впрыскивают первую порцию топлива в количестве 5-15% от общей цикловой подачи топлива в двигатель после завершени  процесса продувки на такте впуска и в цилиндр направл ют из КС 4 топливо- воздушную смесь, а затем дополнитель- ный воздух, который предварительно нагревают или охлаждают. 2 з.п. ф-лы, 2 ил. о (ЛThe invention allows to reduce the mechanical stress of the engine by reducing the dynamics of the cycle, as well as the thermal stress of the additional combustion chamber (CS). Into the cylinder through CS 4 with the help of the inlet valve 10 with the work phases coinciding with the work phases of the inlet valve, an additional 1 1 him of air is supplied, compressed to a pressure that exceeds the pressure of the compressed air supplied to the cylinder through valve 11, When air enters the COP 4 and then in the cylinder through the channel 7 of the valve 10 with the valves 6 and 10 open, through the nozzle 5, the first portion of fuel is injected in an amount of 5-15% of the total fuel supply cycle to the engine after the purging process is completed during the intake stroke and into the cylinder of COP dissolved Aulus 4 fuel-air mixture, and then The additional air which is heated or cooled. 2 hp f-ly, 2 ill. o (l
