Abstract
Exhaust systems for a vehicle are provided. In one example, an exhaust system includes a muffler, a first exhaust outlet pipe fluidly coupled to a first outlet of the muffler, a second exhaust outlet pipe fluidly coupled to a second outlet of the muffler, a bypass duct fluidly coupled to a third outlet of the muffler, and a combined X-Y shaped intersection at which the first exhaust outlet pipe, the second exhaust outlet pipe, and the bypass duct are fluidly coupled to each other.
Claims20
An exhaust system, comprising:
- a muffler;
- a first exhaust outlet pipe fluidly coupled to a first outlet of the muffler;
- a second exhaust outlet pipe fluidly coupled to a second outlet of the muffler;
- a bypass duct fluidly coupled to a third outlet of the muffler;
- and
- a combined X-Y shaped intersection at which the first exhaust outlet pipe, the second exhaust outlet pipe, and the bypass duct are fluidly coupled to each other.
A muffler, comprising:
- a first inlet configured to fluidly couple to a first exhaust passage of an engine;
- a second inlet configured to fluidly couple to a second exhaust passage of the engine;
- a first outlet configured to fluidly couple to a first exhaust outlet pipe;
- a second outlet configured to fluidly couple to a second exhaust outlet pipe;
- and
- a third outlet configured to fluidly couple to a bypass duct, where the first outlet and the second outlet are horizontally aligned and are each positioned vertically above the third outlet, and where the third outlet has a first diameter that is smaller than a second diameter of the first outlet and a third diameter of the second outlet.
An exhaust system, comprising:
- a muffler;
- a first exhaust passage of an engine fluidly coupled to a first inlet of the muffler;
- a second exhaust passage of the engine fluidly coupled to a second inlet of the muffler;
- a first exhaust outlet pipe fluidly coupled to a first outlet of the muffler;
- a second exhaust outlet pipe fluidly coupled to a second outlet of the muffler;
- a bypass duct fluidly coupled to a third outlet of the muffler, the bypass duct having a first cross-sectional area that is smaller than a second cross-sectional area of the first exhaust outlet pipe and a third cross-sectional area of the second exhaust outlet pipe;
- and
- a combined X-Y shaped intersection comprising a bifurcated inlet fluidly coupled to the first exhaust outlet pipe and the second exhaust outlet pipe and a bypass duct inlet fluidly coupled to the bypass duct, where the bypass duct inlet is positioned vertically below the bifurcated inlet.
