摘要:
High pressure regions (31H to 35H) and low pressure regions (31L to 34L) are created based on the exhaust gas flow at curves in an EGR pipe (30), thereby enabling the exhaust gas pressure at inlets (21b to 26b) of gas introduction passages (21a to 26a) to be adjusted. Accordingly, regardless of the number of cylinders or whether the lengths of the flow paths of the EGR pipe (30) are the same, the exhaust pressure at the inlets (21b to 26b) of the gas introduction passages (21a to 26a) can be appropriately adjusted so any difference in pressure of exhaust gas introduced into branch pipes (21 to 26) can be reduced. In this way, the EGR rates of the cylinders can be made closer or the same such that stable combustion can be achieved, thus enabling stable engine operation to be maintained. The EGR pipe (30) is arranged weaving closely between the branch pipes (21 to 26) so space efficiency can be improved and a sufficient amount of exhaust gas can be introduced evenly into the cylinders.
摘要(中):
基于EGR管道(30)中的曲线处的废气流量来产生高压区域(31H至35H)和低压区域(31L至34L),由此使废气压力为 气体引入通道(21a至26a)的入口(21b至26b)被调节。 因此,无论气缸的数量或EGR管道(30)的流路的长度是否相同,气体导入通路(21a〜26a)的入口(21b〜26b)的排气压力都可以 适当地调整,因此能够减少导入分支管(21〜26)的排气的压力差。 这样,汽缸的EGR率可以更接近或相同,从而可以实现稳定燃烧,从而能够保持稳定的发动机运转。 由于EGR管30紧密配置在支管21〜26之间,所以能够提高空间利用率,并且能够将足够量的排气均匀地导入到气缸内。 p>
