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.
