Изобретение относитс к области машиностроени и может быть использовано дл обработки отработавших газов двигател внутреннего сгорани , преимуш,ественно дизел .The invention relates to the field of mechanical engineering and can be used for treating exhaust gases of an internal combustion engine, mainly diesel.
Известен способ каталитической обработки отработавших газов двигател внутреннего сгорани путем подвода к ним топлива и подачи его на катализатор.There is a method of catalytic treatment of exhaust gases of an internal combustion engine by supplying fuel to them and feeding it to the catalyst.
Однако осуществление такого способа довольно затрудпительпо, поскольку, поступа на катализатор, топливо и продукты его разложени усложн ют работу, чрезмерно повыша температуру катализатора. Кроме того, неполное сгорание топлива вызывает повышенное содержание сажи в отработавших газах п образование нагара п кокса, что может привести к дезактивации катализатора.However, the implementation of such a method is rather difficult, since entering the catalyst, the fuel and its decomposition products complicates the operation by excessively raising the temperature of the catalyst. In addition, incomplete combustion of the fuel causes an increased soot content in the exhaust gases and the formation of carbon n and coke, which can lead to deactivation of the catalyst.
Целью изобретени вл етс уменьшение загр знени катализатора сажей.The aim of the invention is to reduce the pollution of the catalyst with soot.
Целью изобретени вл етс уменьшение загр знени катализатора сажей.The aim of the invention is to reduce the pollution of the catalyst with soot.
В основу изобретени поставлена задача осушествить процесс впрыска топлива в таком диапазоне температур, при котором происходит сгорание топлива и сажи, но не происходит окислени других компонентов отработавших газов.The invention is based on the task of improving the fuel injection process in such a temperature range, at which the fuel and soot are burned, but no other components of the exhaust gases are oxidized.

Дл этого топливо подают при температуре катализатора приблизительно от 260 до . Подавать топливо при температуре катализатора нпже 260°С нецелесообразно, поскольку топливо при этой температуре практически не сгорает.For this, the fuel is supplied at a catalyst temperature of from about 260 to. It is impractical to supply fuel at a catalyst temperature of 260 ° C, since the fuel at this temperature practically does not burn.
При температуре катализатора выше 370°С также нецелесообразно подавать топливо, поскольку сажа будет сгорать и без добавлени топлива, а значительное увеличение температуры катализатора усложнит его работу.When the temperature of the catalyst is above 370 ° C, it is also impractical to supply fuel, since soot will burn without adding fuel, and a significant increase in the temperature of the catalyst will complicate its operation.
При осушествлении данного способа нет необходимости использовать отдельные запальные устройства.When implementing this method, there is no need to use separate ignition devices.
Предельные значени температур можно измен ть в зависимости от типа двигател , катализатора и видов топлива, подаваемого на катализатор.The temperature limits may vary depending on the type of engine, catalyst, and types of fuel supplied to the catalyst.
