摘要：
Provided is an engine with an EGR device in which an EGR pipe is cooled easily and a length of the engine is suppressed to be increased by totally improving a structure of an engine case or an arrangement of the EGR pipe.
An engine with an EGR device includes an engine case k, and an EGR pipe 6 that introduces an EGR gas g into an intake path 8, the EGR pipe 6 being arranged to pass through an inside of the engine case k. A part of the EGR pipe 6 in the engine case k is arranged to face a cooling water path in the engine case k. The engine case k is defined by a cylinder head 2. The cooling water path is arranged to surround a whole circumference of the EGR pipe.
