At the same time, air flows from the overpiston space to the front edge of the torch, because a raft is formed on the front front of the torch a cloud consisting of a large number of moving droplets, and a view that allows air to penetrate into the middle of the fuel torch. In addition, the misalignment of the channels and fuel torches leads to the heat; the twisting of the fuel jet The aim of the invention is Intensification of the mixture formation and combustion of the mixture.....; To achieve this goal, the day after the () shn is additionally equipped with hollow conical holes with holes.. - -. .

The npiH4eM cylinder head has a recess in which the piston protrusion is located at the top dead center when the piston is in position.
Двигатель внутреннего сгорани работает следующим образом,The internal combustion engine works as follows
В момент впрыска топлива через многосопловуго форсунку 1 в камеру сгорани 6 оси шипов 8 совпадают с осчми 10 сопл форсунки 1. Вследстви высокого нагрева шипа 8 повьгп аетс температура в центральной зоне факела и ускор етс продесс испарени капель тохглива.At the moment of fuel injection through the multi-nozzle 1 into the combustion chamber 6, the axes of the spikes 8 coincide with the 10 nozzles of the nozzle 1. Due to the high heating of the spike 8, the temperature in the central zone of the torch increases and the evaporation of the drops of toglive is accelerated.
При движении поршн вверх воздух вытесн етс через соединительные каналы 7 и отверсти 11 шипов 8, турбулизирует зар д и создает благопри тные услови дл перемешива ни впрыскиваемого топлива.When the piston moves upward, the air is forced out through the connecting channels 7 and the openings 11 of the spikes 8, turbulizes the charge and creates favorable conditions for mixing neither the injected fuel.
Дл увеличени интенсивности по .дачи воздуха из пристеночной зоны камеры в центральные зоны факелов на поршне 5 и крышке 2 цилиндров 3 Могут быть выполнены выступы, отъедин ющие часть воздушного зар да пристеночной зоны от ее основного объема.In order to increase the air flow rate from the near-wall zone of the chamber to the central zones of the plumes on the piston 5 and cylinder head cover 2, protrusions can be made to separate part of the air charge from the near-wall zone from its main volume.
При этом шипы 8 могут быть размещены на поверхности крышки 2 цилиндров 5, а соединительные каналы 7обраэованы зазором между крышкой 2 цилиндра 3 и днищем 4 поршн 5.In this case, the spikes 8 can be placed on the surface of the cover 2 of the cylinders 5, and the connecting channels 7 are determined by the gap between the cover 2 of the cylinder 3 and the bottom 4 of the piston 5.
Под действием движущегос поршн этот зар д подаетс в центргшьную зону факела.Under the action of a moving piston, this charge is supplied to the centrifugal zone of the torch.
Дл интенсификации 1 урбулизации гор чей смеси шипы изготавливают изIn order to intensify 1 the urbanization of the hot mixture, the spikes are made of
металлов, имеющих различные теплоемкости и теплопроводности, а также выполн ют различной- длины.metals having different heat capacities and thermal conductivities, as well as having different lengths.
Таким образом, достигаетс последовательность воспламенени факелов , распыленного топлива и вли ние на скорость и полноту его выгорани .Thus, a sequence of ignition of torches, atomized fuel and the effect on the speed and completeness of its burnout is achieved.
Подвод нагретого воздушного зар да в центральную зону факела распыленного топлива и нагрев этой зоны поверхност ми шипов в камере сгорани интенсифицируют процессы смесеобразовани и сгорани , происходит более полное сгорание топлива в се- . редине факелов.The supply of heated air charge to the central zone of the atomized fuel plume and the heating of this zone by the spike surfaces in the combustion chamber intensify the processes of mixture formation and combustion, a more complete combustion of the fuel takes place in the north. torches
