Abstract

There is provided an engine device in which a gas purifying filter can be disposed, with high rigidity, in an engine as one of constituent parts of the engine, the need of countermeasures against exhaust gas for each of devices such as vehicles is eliminated, and general versatility of the engine can be enhanced. The engine device includes an engine having an exhaust manifold, and a gas purifying filter which purifies exhaust gas discharged from the engine, front and rear engine leg mounting portions provided on one side surface of the engine include front and rear filter supporting bodies which support the gas purifying filter, the gas purifying filter includes the front and rear filter supporting bodies, and the front and rear filter supporting bodies are connected to the front and rear engine leg mounting portions.

First claim

The invention claimed is:

1. An engine device comprising:
an engine having an exhaust manifold, a cylinder block, cooling fan and an oil pan;
a gas purifying filter which purifies exhaust gas discharged from the engine, a first mounting surface at a first lower side-surface of the engine on a first side of the cylinder block of the engine toward a first end of the engine having the cooling fan;
a second mounting surface at a second lower side-surface of the engine on a second side of a cylinder block opposite the first side toward said first end of the engine having said cooling fan;
a first supporting leg having a first end portion detachably fastened at a first level of the cylinder block to said first mounting surface and having a second end portion, opposite the first end portion, non-removable attached to an outer case of the gas purifying filter: and a second supporting leg having a first end portion detachably fastened at a second level of the cylinder block to said second mounting surface and having a second end portion, opposite the first end portion, non-removable attached to said outer case of the gas purifying filter; and
wherein said first end portion of said first supporting leg and said first end portion of said second supporting leg sandwich a portion of said cylinder block:
wherein the gas purifying filter is disposed below the cooling fan of the engine, opposing a front surface of the oil pan on a lower surface side of the engine: and
an exhaust gas inlet and an exhaust gas outlet disposed outward in the longitudinal direction from said first supporting leg and said second supporting leg on the outer circumferential surface, excluding the end surfaces on both sides in the longitudinal direction, of the gas purifying filter.

2. An engine device comprising an engine having an exhaust manifold, a cylinder block, a flywheel housing, an oil pan and a gas purifying filter which purifies exhaust gas discharged from the engine,
the gas purifying filter is disposed below the flywheel housing of the engine, opposing a front surface of the oil pan on a lower surface side of the engine, and a left and a right filter supporting body that support the gas purifying filter are provided, respectively, on a left and a right engine leg mounting portion, respectively provided on a left and a right side surface of the cylinder block of the engine that the flywheel housing is disposed, and the gas purifying filter is linked through the left and right filter supporting bodies to the engine leg mounting portions;
an exhaust gas inlet and an exhaust gas outlet disposed outward in the longitudinal direction from the left and right filter supporting bodies on the outer circumferential surface, excluding the end surfaces on both sides in the longitudinal direction, of the gas purifying filter; and
wherein one end portion of each one of the left and right filter supporting bodies is attached to the outer circumferential surface of the gas purifying filter, and an opposite end portion of the left and right supporting bodies is detachably attached to the left and right engine leg mounting portions of the cylinder block, said left and right filter supporting bodies at said opposite end sandwiching a portion of the cylinder block of the engine.
