Description

и служащий дл  перекрыти  выходных окон 5 на режиме принудительного холостого хода.and serving to shut off the output windows 5 in the mode of forced idling.

Запорный орган 17 (см. фиг. 1) может быть выполнен за одно целое с винтом качественного регулировани  состава смеси.The locking member 17 (see Fig. 1) can be made in one piece with the screw for qualitative adjustment of the mixture composition.

На режиме холостого хода во впускной тракт двигател  подаетс  из канала холостого хода топливо-воздушна  смесь (траектори  показана пунктирными лини ми). Выход щий из сопла 12 дополнительный воздух обеспечивает перемешивание топлива и воздуха и испарение жидкой фазы топлива.In idle mode, the engine air intake manifold is fed into the engine intake tract from the idle channel (the trajectory is shown in dashed lines). The additional air discharged from the nozzle 12 provides for mixing of the fuel and air and evaporation of the liquid phase of the fuel.

Гомогенизаци  смеси осуществл етс  как в проточном канале 18 проставки 6, так и в канале 19 впускного трубопровода 7.The homogenization of the mixture is carried out both in the flow channel 18 of the spacer 6 and in the channel 19 of the inlet pipe 7.

Торцова  поверхность 20 выступа 9 выполнена под острым углом к торцовой поверхности фланца карбюратора. Благодар  этому обеспечиваетс  подача потока дополнительного воздуха под тупым углом к направлению движени  смеси из канала холостого хода, что повыщает турбулизацию потока смеси, интенсифицирует испарение жидкой фазы топлива и перемешивание паров последнего с воздухом .The end surface 20 of the protrusion 9 is made at an acute angle to the end surface of the carburetor flange. Due to this, additional air is supplied at an obtuse angle to the direction of movement of the mixture from the idling channel, which increases the turbulence of the mixture flow, intensifies evaporation of the liquid phase of the fuel and mixing of the latter vapor with air.

Дл  повышени  одпородности смеси при соосном расположении карбюратора 1, проставки 6 и впускного трубопровода 7 диаметр канала 13 выполн етс  меньше диаметра канала 18 примерно на 0,2 мм, что обеспечивает пе- .ft 506314To increase the uniformity of the mixture with coaxial arrangement of the carburetor 1, spacer 6 and inlet pipe 7, the diameter of the channel 13 is smaller than the diameter of the channel 18 by about 0.2 mm, which provides 506314

рекрытие фланцем карбюратора 1 выступа 9 на 0,1 мм. Соответственно диаметр канала 18 меньше диаметра канала 19 также на 0,2 мм.the flange of the carburetor 1 protrusion 9 by 0.1 mm. Accordingly, the diameter of the channel 18 is less than the diameter of the channel 19 by 0.2 mm.

Claims (2)

1.Устройство дл  гомогенизации смеси в двигателе внутреннего сгорани , содержащее карбюратор с каналом холостого хода и дроссельной заслонкой, имеющей утолщение дл 1. A device for homogenizing the mixture in an internal combustion engine, containing a carburetor with an idling channel and a throttle valve having a thickening for перекрыти  окон канала, и размещенную между карбюратором и впускным трубопроводом проставку, снабженную пазом и выступом , образующими с торцовой поверхностью фланца карбюратора соединенную с источником дополнительного воздуха камеру с выходным соплом, имеющим длину по дуге окружности проточного канала карбюратора 30-40°, отличающеес  тем, что, с целью увеличени  полноты сгорани  топлива и снижени  токсичности отработавщих газов, в канале холостого хода установлен подвижный запорный орган, св занный с системой управлени , например, электронной или вакуумной.blocking the channel windows and a spacer placed between the carburetor and the inlet pipe, provided with a groove and a protrusion, forming a chamber with an outlet nozzle having a 30-40 ° length along the circumference of the carburetor flow channel, which is different from the carburetor flange; that, in order to increase the completeness of the combustion of fuel and reduce the toxicity of exhaust gases, a movable shut-off organ is installed in the idle channel associated with a control system, for example, electronic or vacuum. 2.Устройство по п. 1, отличающеес  тем, что, с целью обеспечени  подачи дополнительного воздуха под тупым углом к направлению движени  смеси из канала холостого хода, торцова  поверхность выступа выполнена под острым углом к торцовой поверхности фланца карбюратора.2. The device according to claim 1, characterized in that, in order to provide additional air at an obtuse angle to the direction of movement of the mixture from the idling channel, the end surface of the protrusion is made at an acute angle to the end surface of the carburetor flange. лl LL 5 12 205 12 20 Фиг 3Fig 3
