    • 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.
    • 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。

    • An internal combustion engine 10 comprises a device having a mechanism that moves a cylinder block relative to a crankcase, a worm wheel (wheel) 54 fixed to the mechanism, and a worm 55 meshed with the wheel. The device is disposed at the position in the vicinity of an disposed-face OS1 and within the disposed-face when the disposed-face is viewed from the front. The internal combustion engine drives the worm for rotatably driving the wheel to drive the mechanism. The internal combustion engine has a noise shielding members 61, 62, and 83 arranged so as to cover a meshing portion EG where the wheel and the worm are meshed with each other, when the disposed-face is viewed from the front. The noise generated at the meshing portion is attenuated by the noise shielding member, and propagated to the outside of the internal combustion engine. Consequently, the noise heard at the outside is reduced.
    • 内燃机10包括具有使气缸体相对于曲轴箱移动的机构的装置,固定在机构上的蜗轮(轮)54和与车轮啮合的蜗杆55。 当从前面观察设置面时,该装置设置在配置面OS1附近的位置和配置面内。 内燃机驱动蜗杆以可旋转地驱动车轮以驱动机构。 当从前方观察配置面时,内燃机具有布置成覆盖轮和蜗杆彼此啮合的啮合部EG的噪声屏蔽构件61,62和83。 在啮合部分产生的噪声被噪声屏蔽部件衰减,传播到内燃机的外部。 因此,外界听到的噪音减少了。
