Abstract
An EGR passage of an EGR device includes a plurality of EGR introduction passages and an EGR chamber. A plurality of cylinders include a first cylinder subset and a second cylinder subset, each of which is a pair of two cylinders positioned next to each other. An explosion interval between the two cylinders constituting the first cylinder subset is shorter than that of the second cylinder subset. A first total volume being the sum of volumes of two first EGR introduction passages associated with the first cylinder subset and a volume of a portion of the EGR chamber located between the two first EGR introduction passages is larger than a second total volume being the sum of volumes of two second EGR introduction passages associated with the second cylinder subset and a volume of a portion of the EGR chamber located between the two second EGR introduction passages.
