Изобретение относитсй к машиностроению и может быть использовано при производстве дизелей преимущест- венно с газотурбинньЕМ наддувом.The invention relates to mechanical engineering and can be used in the production of diesel engines mainly with gas turbine supercharging.
Цель изобретени - улучшение приемистости дизел .The purpose of the invention is to improve diesel pickup.
На фиг. 1 представлена сх ема предлагаемой системы; на фиг. 2 - узел I на фиг. 1; на фиг. 3 - схема подключени системы через наход щийс под давлением резервуар.FIG. 1 shows the scheme of the proposed system; in fig. 2 — node I in FIG. one; in fig. 3 is a diagram of connecting the system through a pressurized reservoir.
Компрессор 1 соединен с цилиндрами 2 двигател посредством впускного трубопровода 3. К турбине 4, кинематически св занной с компрессором 1, подсоединен выпускной трубопровод 5 двигател . Трубопровод 6 предназначен дл подачи топлива в цилиндры 2 двигател от его топливной системы (не показано). Во впускном трубопроводе 3 размещена дополнительна рас- пыливающа форсунка 7, котора подключена трубопроводом 8 к топливной системе двигател через запорный клапан 9, св занный с задатчиком режима работы дизел . Форсунка 7 может быть подключена к трубопроводу 8 через наход щийс под давлением от постороннего источника 10 воздуха резервуар 11.The compressor 1 is connected to the cylinders 2 of the engine through the intake manifold 3. To the turbine 4, kinematically connected with the compressor 1, is connected to the exhaust manifold 5 of the engine. Pipeline 6 is designed to supply fuel to the cylinders 2 of the engine from its fuel system (not shown). In the inlet pipe 3, an additional spray nozzle 7 is placed, which is connected by pipe 8 to the engine fuel system via a shut-off valve 9 connected to the diesel engine operation unit. The nozzle 7 can be connected to the pipeline 8 through a reservoir 11 which is under pressure from an external source of air 10.
В процессе работы двигател воздух в цилиндры подаетс от компрессора 1 по впускному трубопроводу 3, аIn the course of engine operation, air is supplied to the cylinders from compressor 1 via intake manifold 3, and

топливо подаетс из топливной системы по трубопроводу 6. В момент на- броса на дизель нагрузки по команде от задатчика режима работы дизел 5 открываетс запорный клапан 9, сое- . дин гощий топливную систему двигател с дополнительной распыливак цей форсункой 7. При этом происходит рас- пыл дополнительного количества топ10 лива во впускном трубопроводе 3, образование хорошо перемешанной топли- вовоздушной смеси и подача ее в цилиндры . Улучшение смесеобразовани даже при невысоком значении общегоfuel is supplied from the fuel system through pipeline 6. At the moment of launching a diesel load, on command from the unit for setting the operating mode of diesel 5, a shut-off valve 9 opens, connecting. The engine is fueling a fuel system with an additional spray nozzle 7. In this case, an additional amount of top 10 is dispersed in the intake manifold 3, a well-mixed fuel-air mixture is formed and fed to the cylinders. Improving the mixture formation even at a low total
15 коэф(1)ициента избытка воздуха позвол ет уменьшить неполноту сгорани топлива в переходном режиме, увеличить развиваемьтй крут щий момент и улучшить приемистость дизел . Топли20 во к форсунке 7 может подаватьс из резервуара 11, давление в котором создаетс посторонним источником 10 воздуха.15 coefficients (1) of excess air permits to reduce the incompleteness of fuel combustion in a transient mode, to increase the developed torque and improve the acceleration of diesel. The fuel 20 in to the nozzle 7 can be supplied from the reservoir 11, the pressure in which is created by the foreign air source 10.
Применение предлагаемой системыApplication of the proposed system
