A method of controlling an adjustable exhaust system for a marine engine includes receiving a vessel location of a marine vessel having an adjustable exhaust system and identifying a noise constraint based on the vessel location. A current exhaust mode of the adjustable exhaust system is identified. A determination is then made regarding whether the exhaust system is exceeding the noise constraint based on the current exhaust mode. If the noise constraint is exceeded, an instruction is generated to adjust the adjustable exhaust system to comply with the noise constraint.

Scalable greenhouse gas capture systems and methods to allow a user to off-load exhaust captured in an on-board vehicle exhaust capture device and to allow for a delivery vehicle or other transportation mechanism to obtain and transport the exhaust. The systems and methods may involve one or more exhaust pumps, each with an exhaust nozzle corresponding to a vehicle exhaust port. Upon engagement with the vehicle exhaust port, the exhaust nozzle may create an air-tight seal between the exhaust nozzle and the vehicle exhaust port. A first pipe may be configured to transport captured exhaust therethrough from the exhaust nozzle to. The captured exhaust may be at least temporarily stored in an exhaust holding tank connected to and in fluid communication with the first pipe.

An exhaust gas after-treatment device in a driveline application, which device comprising a casing having an upper surface, a lower surface and side surfaces connecting the upper and lower surfaces to form an enclosed volume. The casing is provided with an exhaust inlet opening and an exhaust outlet opening wherein exhaust gas is supplied to and discharged from the casing through the upper surface. At least one of the exhaust inlet and outlet openings is operatively connected to its corresponding inlet or outlet pipe by a pipe connector having a first opening facing the casing and a second opening facing away from the casing. The at least one pipe connector is arranged to be rotatable about the central axis of its associated inlet or outlet opening in the casing into a predetermined angular position relative to the opening in the casing.

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.

The adjustable exhaust backpressure device allows for post-installation adjustment of additional backpressure. This allows a user to adjust how much backpressure is generated by testing, adjusting, and then re-testing. The adjustment can generally be performed without removing the device from the exhaust, and without replacing any parts. The adjustable exhaust backpressure device can be placed in any location following the engine. The adjustable exhaust backpressure device includes a body with an exhaust inlet and an exhaust outlet.
