Description

一种八缸柴油机脉冲增压排气管
技术领域
本发明涉及一种八缸柴油机,尤其涉及一种八缸柴油机脉冲增压排气管。
背景技术
现有的八缸柴油机脉冲增压排气管采用直列式,包括一台端置的废气涡轮双进口增压器、八根排气支管、四根排气总管和两根二合一脉冲转换器,其排气总管或排气支管的连接处设有金属波纹管或金属垫片。该增压排气管不仅管件繁多,结构复杂,而且占地面积大,成本高。
发明内容
本发明的目的在于提供一种结构简单、紧凑的八缸柴油机脉冲增压排气管。
本发明的目的是这样实现的,一种八缸柴油机脉冲增压排气管,包括排气总管和排气支管,其特征在于:所述排气总管和排气支管为共壁管。
为了提高排气效率,上述两个排气支管与一个排气总管为共壁管。
    为了结构紧凑,布局合理,上述八缸柴油机中的一号缸排气支管、八号缸排气支管与一个排气总管为共壁管,二号缸排气支管、七号缸排气支管与一个排气总管为共壁管,三号缸排气支管、六号缸排气支管与一个排气总管为共壁管,四号缸排气支管、五号缸排气支管与一个排气总管为共壁管。
为了进一步简化结构,上述排气总管为四根且通过一根四合二脉冲转换器与增压器连接。
    为了防止由于热胀冷缩造成排气管变形,上述排气总管的连接处设有波纹管。
本发明具有如下有益效果,本发明的排气总管和排气支管为共壁管,且通过一根四合二脉冲转换器将四根排气总管与增压器连接,不仅结构简单,紧凑,减少了管件,降低了成本,而且减少了管道压力损失,提高了柴油机工作效率。

图2为图1的俯视图;
图3为图2 A-A截面图;
图4为图2 B-B截面图;
图5为图2 C-C截面图。
具体实施方式
 实施例,一种八缸柴油机脉冲增压排气管,包括排气总管1和排气支管2,排气总管1为四根且通过一根四合二脉冲转换器4与增压器连接;其中,两个排气支管2与一个排气总管1为共壁管3;该八缸柴油机中的一号缸排气支管2、八号缸排气支管2与一个排气总管1为共壁管3,二号缸排气支管2、七号缸排气支管2与一个排气总管1为共壁管3,三号缸排气支管2、六号缸排气支管2与一个排气总管1为共壁管3,四号缸排气支管2、五号缸排气支管2与一个排气总管1为共壁管3;共壁管3的连接处设有波纹管5。
