Abstract
Systems and methods are provided for a combined spark arrestor and muffler assembly. In one example, a system may include a combined housing, the combined housing including a spark arrestor portion including a plurality of stator fins, and a muffler portion including acoustic packing, the muffler portion fluidically coupled to the spark arrestor portion via a first sliding joint and a second sliding joint. In this way, a single component of a vehicle exhaust system may reduce sparks and/or carbon deposits in exhaust gas, while also reducing exhaust noise.
Claims20
A system, comprising:
- a first combined housing, comprising:
- a spark arrestor portion, the spark arrestor portion including a plurality of stator fins;
- and
- a muffler portion, the muffler portion including acoustic packing, wherein the muffler portion is fluidically coupled to the spark arrestor portion via a first sliding joint and a second sliding joint.
An apparatus, comprising:
- a cylindrical casing including an internal cavity, the internal cavity comprising a first cylindrical portion and a second cylindrical portion, the first cylindrical portion perpendicular to the second cylindrical portion;
- an exhaust gas inlet extending between the internal cavity and an exterior surface of the cylindrical casing, the exhaust gas inlet positioned on a first end of the cylindrical casing;
- an exhaust gas outlet extending between the internal cavity and the exterior surface of the cylindrical casing, the exhaust gas outlet positioned on a second end of the cylindrical casing;
- a plurality of stator fins positioned within the first cylindrical portion of the internal cavity;
- and
- an insulating material positioned radially around the second cylindrical portion of the internal cavity.
A system, comprising:
- an exhaust gas passage extending between an exhaust gas inlet and an exhaust gas outlet, a face of the exhaust gas inlet perpendicular to a face of the exhaust gas outlet, the exhaust gas passage including a plurality of stator fins, and at least a portion of the exhaust gas passage encased in an insulating material;
- a spark tray coupled to the exhaust gas passage;
- and
- a drain port coupling an internal surface of the exhaust gas passage to an external surface of the exhaust gas passage.
