Abstract
Methods and systems are provided for an exhaust system of a vehicle. In one example, the exhaust system includes an exhaust tail pipe with an asymmetric outlet. The asymmetric outlet of the tail pipe may flare outwards, away from a central axis of the tail pipe, circumferentially surrounded by a housing with a geometry matching a geometry of the asymmetric outlet.
Claims20
An asymmetric exhaust tail pipe outlet, comprising;
- a first flared extension, sloping outwards and away from a central axis of the exhaust tail pipe outlet from a first end to a second end of the outlet, sharing an inner surface with surrounding portions of the exhaust tail pipe outlet;
- and
- a second flared extension, opposite of the first flared extension, sloping outwards and away from the central axis from the first end to the second end to a lesser extent than the first flared extension and also sharing the inner surface of the exhaust tail pipe outlet.
An exhaust assembly, comprising;
- a tail pipe;
- a flared, asymmetric outlet, continuous with the tail pipe and increasing in area from a first, upstream end to a second, downstream end of the outlet, the area perpendicular to a central axis of the tail pipe;
- and
- an enclosure at least partially circumferentially surrounding the outlet and having at least one section flaring outward, away from the central axis of the tail pipe.
1 more element
An exhaust system for a vehicle, comprising;
- an exhaust passage, configured to flow exhaust gases, with an asymmetric outlet, the asymmetric outlet including a first flared side and a second flared side, the second side opposite of the first side;
- and
- a housing at least partially circumferentially surrounding the asymmetric outlet with one section flaring in a direction of the first flared side of the asymmetric outlet and configured to couple to an outer panel of the vehicle.
