Engine device
An engine device including an exhaust gas purification device above cylinder head through a support pedestal. The support pedestal has a flat portion on which the exhaust gas purification device is mounted, and a plurality of legs which protrude downward from the flat portion and are fixed to the cylinder head. The flat portion and the leg portions are formed integrally. Portions between the legs are each formed in an arch-shape.
1. An engine device, comprising:
an exhaust gas purification device provided via a support pedestal;
a cylinder head with a cylinder head cover; and
a cooling air passage, in which cooling air from a cooling fan flows, formed between the cylinder head cover on the cylinder head and the support pedestal.
2. The engine device according to claim 1 , wherein the support pedestal comprises a mounting portion on which the exhaust gas purification device is mounted, and a plurality of legs fixed to the cylinder head.
3. The engine device according to claim 2 ,
wherein the support pedestal is arranged above one side surface of two side surfaces of the cylinder head that intersects an exhaust side surface and an intake side surface of the cylinder head, and includes as leg portions, an exhaust side leg portion fixed to the exhaust side surface, an intake side leg portion fixed to the intake side surface, and a central leg portion fixed to the one side surface.
4. The engine device according to claim 3 , wherein the cooling fan is provided on the other side surface side of the two side surfaces of the cylinder head.
5. The engine device according to claim 3 , further comprising:
a configuration including an EGR device that returns a part of the exhaust gas discharged from an exhaust manifold to an intake manifold as EGR gas, an EGR cooler that cools the EGR gas, and an exhaust pressure sensor that detects exhaust gas pressure in the exhaust manifold,
wherein the EGR cooler and the exhaust pressure sensor are attached to the one side surface of the cylinder head.
6. The engine device according to claim 3 , wherein an intake manifold is provided on the intake side surface of the cylinder head and the intake side leg portion is fixed to the intake manifold.
