Изобретение относитс к двигателестроению , в частности двигател м внутреннего сгорани с воспламенением от сжати .FIELD OF THE INVENTION The invention relates to engine-building, in particular compression-ignition internal combustion engines.
Известны двигатели внутреннего сгорани с воспламенением от сжати , содержащие основную камеру сгорани , дополнительную цилиндрическую камеру со вставкой , размещенную в головке цилиндра и сообщенную с основной камерой, и форсунку , установленную в верхней части дополнительной камеры 1.Known internal combustion engines with compression ignition, containing the main combustion chamber, an additional cylindrical chamber with an insert placed in the cylinder head and communicated with the main chamber, and a nozzle installed in the upper part of the additional chamber 1.
Однако указанный двигатель характеризует недостаточно высокое качество смесеобразовани и сгорани .However, this engine is characterized by an insufficiently high quality of mixture formation and combustion.
Цель изобретени - повышение экономичности и унижение токсичности путем улучшени смесеобразовани и сгорани .The purpose of the invention is to increase the economy and reduce the toxicity by improving the mixture formation and combustion.
Указанна цель достигаетс тем, что вставка размешена соосно с форсункой и выполнена с конфузорным участком, большее сечение которого обращено к форсунке , и ступенчатым участком увеличенного сечени , расположенным у входа в основную камеру, причем вставка размещена в дополнительной камере с кольцевым ,зазором , величина которого в сечении ступенчатого у частка не превышает его велиЧИНЫ в наибольшем сечении конфузорного участка.This goal is achieved in that the insert is placed coaxially with the nozzle and is made with a confused section, the larger section of which is facing the nozzle, and a stepped section of increased section located at the entrance to the main chamber, the insert being placed in an additional chamber with an annular gap, the size of which in the section of the stepped section, it does not exceed its size in the largest section of the confused section.
На чертеже показана дополнительна камера со вставкой предлагаемого двигател внутреннего сгорани , продольный разрез.The drawing shows an additional chamber with an insert of the proposed internal combustion engine, a longitudinal section.
Двигатель внутреннего сгорани содержит основную камеру сгорани (не показана ) дополнительную камеру 1 цилиндрической формы и форсунку 2.The internal combustion engine contains the main combustion chamber (not shown) additional chamber 1 of cylindrical shape and nozzle 2.
Дополнительна камера размешена в Additional camera placed in
10 головке цилиндра 3 и в ней размещена вставка 4. Вставка 4 устанавливаетс в дополнительной камере 1 соосно с форсункой посредством трех штифтов 5.10 to the cylinder head 3 and the insert 4 is placed in it. The insert 4 is installed in the additional chamber 1 coaxially with the nozzle by means of three pins 5.
Вставка 4 выполнена с конфузорным участком 6, большее сечение 7 которого Box 4 is made with confused section 6, the larger section 7 of which
15 обращено к форсунке, и ступенчатым участком 8 (срывным диффузором) с увеличенным сечением относительно среднего участка 9, расположенным у входа 10 в основную камеру сгорани . Вставка 4 разме20 шена в дополнительной камере 1 с кольцевым зазором 11. Величина кольцевого зазора 11 в сечении ступенчатого участка 8 (срывного диффузора) не превышает величины кольцевого зазора 12 в наиболь15 is facing the nozzle, and a stepped section 8 (shear cone) with an increased cross-section relative to the middle section 9, located at the entrance 10 to the main combustion chamber. The insert 4 is spaced in the additional chamber 1 with an annular gap 11. The magnitude of the annular gap 11 in the cross section of the stepped section 8 (stall diffuser) does not exceed the magnitude of the annular gap 12 in most
