Abstract

An engine has an ATD that purifies exhaust gas. The engine is provided with an engine body, a support base, a front-side support bracket, and a rear-side support bracket. The support base supports an exhaust gas purification device. The front-side support bracket is mounted to the engine body and is disposed on one side of the engine body, and supports the support base. The rear-side support bracket is mounted to the engine body and is disposed on a side opposite to the front-side support bracket with the engine body therebetween, and supports the support base. The front-side support bracket has a vertically-mounted boss mounted in the vertical direction with respect to the support base. The rear-side support bracket has a horizontally-mounted boss mounted in the horizontal direction with respect to the support base.

First claim

The invention claimed is:

1 . An engine having an exhaust gas purification device that purifies exhaust gas, the engine comprising:
an engine body; a support base having at least a curved shape along outer peripheral surfaces of the exhaust gas purification device to mount the device thereon; a support bracket on one side of the engine body to be mounted on the engine body, so as to support the support base; and wherein the support bracket has a bracket mounting part at a lower surface of the curved shape of the support base.

2 . The engine according to claim 1 comprising:
a flywheel; and
a cooling fan to rotate for cooling,
wherein the cooling fan and the flywheel are arranged on sides that are opposite to each other in relation to the engine body interposed therebetween,
the support bracket has a first bracket and a second bracket, wherein
the first support bracket is arranged on the cooling fan side, and
the second support bracket is arranged on the flywheel side.

3 . The engine according to claim 2 further comprising:
a third support bracket on a side that is different from any of the side of the engine body on which the first support bracket is arranged and the side on which the second support bracket is arranged; and
a fourth support bracket on an opposite side of the engine body in relation to the third support bracket,
wherein the third support bracket and the fourth support bracket are configured at least with a first component to be mounted on the engine body and a second component to be mounted on the support base.

4 . The engine according to claim 1 comprising
a mounting member to mount the exhaust gas purification device onto the support base,
wherein the support base is equipped with a plurality of fixing parts capable of fixing the mounting member.

5 . The engine according to claim 1 wherein the exhaust gas purification device is installed parallel to an axial direction of the engine body.

6 . An engine comprising:
an engine body; an exhaust gas purification device that purifies exhaust gas; a support base having at least a curved shape along outer peripheral surfaces of the exhaust gas purification device for mounting the device thereon; a support bracket on one side of the engine body to be mounted on the engine body, so as to support the support base; and a bracket mounting part for mounting the support bracket, wherein the support bracket is mounted on the bracket mounting part at a lower surface of the curved shape of the support base.
