Изобретение относитс  к машиностроению , а именно двигателестрое:нию ,в частности к организации рабочих процессов в дизеле с разделенной камерой сгорани .The invention relates to mechanical engineering, namely engine building, in particular, to the organization of work processes in a diesel engine with a divided combustion chamber.

Известны, способы смесеобразовани  и воспламенени  в дизеле путем подачи воздуха в надпоршневое пространство , отделени  части воздуха и размещени  ее в дополнительной емкости посто нного объема, сжати  воздуха в надпоршневом пространстве с частичным вытеснением сжатого воздуха в дополнительную емкость и впрыска топлива в дополнительную емкость дл  воспламенени  и последующего истече ни  продуктов неполного сгорани  в надпоршневое пространство Methods are known for mixing and igniting in a diesel engine by supplying air into the overpiston space, separating a part of the air and placing it in an additional tank of constant volume, compressing the air in the over piston space with partial displacement of compressed air into the additional tank and injecting fuel into the additional tank for ignition and the subsequent expiration of the products of incomplete combustion in the supra piston space

Однако из-за необходимости подбирать сечение канала дл  обеспечени  стабильного смесеобразовани  и начала горени  в определенный момент времени данный способ отличаетс  сложностью и недостаточной надежностью регулировани  начала процесса смесеобразовани  и горени .However, due to the need to select a channel section to ensure stable mixing and start of combustion at a certain point in time, this method is characterized by complexity and insufficient reliability of controlling the start of the process of mixing and burning.

Целью изобрет.ени   вл етс  улучшение стабильностиначала процесса воспламенени .The aim of the invention is to improve the stability of the ignition process.

Дл  достижени  поставленной цели сжатый воздух .в процессе вытеснени  дел т на два потока, один из которыхTo achieve this goal, the compressed air is divided into two streams during the displacement process, one of which

перемешивают с топливом, подаваемым в дополнительную емкость, а вторым при открытии дополнительного канала воспламен ют образовавшуюс  смесь. На чертеже показан двигатель внутреннего сгорани , продольный разрез по камере сгорани .mixed with fuel supplied to the additional tank, and the second when the additional channel is opened, the resulting mixture ignites. The drawing shows the internal combustion engine, a longitudinal section through the combustion chamber.

Камера сгорани  дизел  разделена на две части основную 1, сосредоточенную в надпоршневом пространствеDiesel combustion chamber is divided into two parts: the main one, concentrated in the above piston space.

цилиндра и дополнительную емкость 2, сообщающиес  между собой соединительным каналом 3 и дополнительным каналом 4, перекрываемым клапаном 5. Соединительный канал 3 соединен питающим .каналом 6 с промежуточнойa cylinder and an additional container 2, which are interconnected by a connecting channel 3 and an additional channel 4, closed by a valve 5. The connecting channel 3 is connected by a supply channel 6 to an intermediate

камерой 7, в которую подаетс  топливо из подвод щей магистрали 8 через обратный клапан 9. С помощью канала 10 малого сечени  промежуточна  камера 7 соединена с основной камерой 1. Канал 4 выполнен с сечением, обеспечивающим минимальное гидравлическое сопротивление при перетекании газа из дополнительной емкости 2 вa chamber 7 into which fuel is supplied from the supply line 8 through a check valve 9. With the help of a channel 10 of a small section, the intermediate chamber 7 is connected to the main chamber 1. Channel 4 is made with a cross section providing minimum hydraulic resistance when gas flows from the additional tank 2 into
