Abstract
Provided is an engine device for which an increase in width can be suppressed due to the size of an EGR cooler. The engine device comprises: a cylinder block; a cylinder head; an exhaust manifold; and an EGR cooler. The cylinder head is disposed above the cylinder block. The exhaust manifold is disposed on one side surface of the cylinder head and circulates exhaust gas exhausted from the cylinder head. The EGR cooler is disposed below the exhaust manifold and cools EGR gas constituting a portion of the exhaust gas exhausted from the exhaust manifold.
Claims12
An engine device comprising:
- a cylinder block;
- a cylinder head located above the cylinder block;
- an exhaust manifold, located on one side surface of the cylinder head to distribute exhaust gases exhausted from the cylinder head and, and having a pipe section;
- an EGR gas inlet connected to the cylinder head via the pipe section of the exhaust manifold;
- and
- an EGR cooler,
- fixed to a side surface of the cylinder block at a bottom surface of the EGR cooler and
- located below the exhaust manifold to cool EGR gas that is part of the exhaust gases exhausted from the exhaust manifold, and
- extended along a longitudinal direction of the exhaust manifold and located within a length of the exhaust manifold.
