Abstract: An exhaust pipe includes a first end, a second end, and a wall connecting the first end to the second end. The first end has a first opening, and the second end has a second opening that fluidly communicates with the first opening to define a bore. The wall includes an inner curved second and an outer curved section that includes an indentation. The indentation includes a first inwardly extending part and a second inwardly extending part. The second inwardly extending part includes a through hole having an inner opening and an outer opening. The inner opening is located between the outer opening and the second opening. A diameter of the outer opening is less than a diameter of the inner opening. A thickness of the second inwardly extending part is less than the diameter of the outer opening.

Abstract: A reductant delivery system for an engine system. The engine system includes an engine having an exhaust conduit and a turbocharger with a compressor. The reductant delivery system having an injector, a storage system, a sensor and a controller. The injector is configured to inject a reductant into the exhaust conduit. The storage system stores the reductant and is configured to receive pressurized air from the compressor. The sensor is configured to determine a pressure of the pressurized air in the storage system. The controller is in communication with the sensor and is configured to increase a power output of the engine in response to the pressure being below a desired pressure.
