Abstract
An air intake route leads air drawn in from outside into a diesel engine. The air intake route is provided with an air intake manifold and an EGR device is provided which supplies some of the exhaust to the air intake route. An introduction path for introducing exhaust supplied from the EGR device is provided inside of the air intake manifold, and an exhaust port of the introduction path is arranged downstream from and near the intake entrance in the air intake manifold. By this means, exhaust gas performance can be improved without increasing the engine size.
