Exhaust system for firefighting vehicle

A vehicle, comprising:

• an engine;
• a chassis;
• and
• an exhaust system, including:
• a diesel particulate filter having a first end and a second end both supported along a first lateral side of the chassis;
• a selective catalytic reduction device having a first end and a second end both supported along a second lateral side of the chassis opposite the first lateral side, wherein the diesel particulate filter and the selective catalytic reduction device are supported at the same height relative to the chassis;
• a first conduit coupled between the engine and the diesel particulate filter;
• a second conduit coupled between the diesel particulate filter and the selective catalytic reduction device;
• and
• a third conduit having a first end coupled to the selective catalytic reduction device and at least one second end open to the environment.

A vehicle comprising:

• a chassis having a longitudinal direction, the chassis including a first frame member and a second frame member;
• an engine coupled to the chassis, wherein the first frame member and the second frame member are spaced apart from each other in a lateral direction to provide a cavity that receives the engine;
• and
• an exhaust system supported at the engine, the exhaust system comprising a diesel particulate filter coupled to the first frame member with a first bracket and having a first end and a second end both supported at a first lateral side of the chassis such that the diesel particulate filter is positioned along the longitudinal direction of the chassis, a selective catalytic reduction device coupled to the second frame member with a second bracket and having a first end and a second end both supported at a second lateral side of the chassis opposite the first lateral side such that the selective catalytic reduction device is positioned along the longitudinal direction of the chassis, a first conduit coupled between the engine and the diesel particulate filter, a second conduit coupled between the diesel particulate filter and the selective catalytic reduction device and a third conduit having a first end coupled to the selective catalytic reduction device and at least one second end open to the environment,
• wherein the first bracket supports the diesel particulate filter at a position that is at least partially outside of an outer surface of the first frame member and below a bottom surface of the first frame member.
