The present system implements rapid ventilation and ensures precise control and stabilisation of pressure difference.

Provided is an exhaust fumes reduction device for an internal combustion engine. The device reduces the generation of exhaust fumes and improves output and fuel efficiency by smoothing the discharge flow of exhaust gas in a state additionally mounted at the end of an exhaust line of an internal combustion engine. The exhaust fumes reduction device includes; a housing pipe connected to the end of the exhaust port to discharge exhaust gas; a vortex pipe mounted inside the housing pipe to increase the speed of the exhaust gas introduced into the housing pipe and discharge the exhaust gas spirally; and an external pipe mounted on the outside of the housing pipe and in communication with the housing pipe to allow the outside air to flow in and to assist the smooth discharge of exhaust gas discharged to the housing pipe.

An arrangement for a marine vessel, comprising a combustion unit arranged in an engine room of the marine vessel, an exhaust gas cleaning system in flow connection with the combustion unit and being arranged for receiving and for cleaning the exhaust gas from the combustion unit to a cleaned exhaust gas, a cleaned gas exhaust pipe being in flow connection with the exhaust gas cleaning system and arranged for receiving the cleaned exhaust gas, a plume control system, comprising an air intake for taking in ambient air, a heater for heating the ambient air producing heated air, and a gas mixer placed in the cleaned gas exhaust pipe and arranged for mixing the cleaned exhaust gas in the cleaned gas exhaust pipe with the heated air resulting in an exhaust gas mixture that is blown out into the atmosphere via the one or more exhaust gas outlets.

An exhaust plume control structure includes a mounting member configured to mount to an exhaust flow source. At least one divider member operatively couples to the mounting member and is positioned in fluid communication with the exhaust flow source. A diverter member operatively couples to the divider member(s) to radially direct an initial exhaust flow from the exhaust plume towards the divider member(s). Each divider member separates the initial exhaust flow into a plurality of exhaust flows. A number of peripherally spaced, radially extending vanes may also separate the exhaust flows into additional exhaust flows. Each of the additional exhaust flows has a slower velocity than the initial exhaust flow. The structure reduces exhaust flow velocity and may provide back pressure to the initial exhaust flow. A power generating plant including the structure is also disclosed.

An internal combustion engine includes an exhaust conduit having an exhaust port fluidically coupled to ambient fluid and having an internal cross-sectional area and an engine cylinder fluidically coupled to the exhaust conduit. A fluidic amplifier is disposed within the exhaust conduit and is fluidically coupled to the engine cylinder. The amplifier is further fluidically coupled to a source of primary fluid and is configured to introduce the primary fluid and at least a portion of fluid from the engine cylinder to the exhaust port.

An assembly for braking the displacement of a tailpipe cover is disclosed. The assembly has a clamping element with an elastic material, a tailpipe, and a tailpipe cover. The clamping element is arranged at least indirectly on the tailpipe and on the tailpipe cover. A section of the clamping element extends over the tailpipe in the axial direction parallel to the longitudinal axis of the tailpipe cover. The distance between the longitudinal axis and the clamping element is designed to be at least partly shorter than the distance between the longitudinal axis and the tailpipe in said clamping element section. Alternatively or in addition thereto, at least one section of the clamping element is arranged at least indirectly against the tailpipe in an immovable manner in the direction of the longitudinal axis.

The present application relates to an arrangement for a marine vessel, comprising a combustion unit arranged in an engine room of the marine vessel, an exhaust gas cleaning system in flow connection with the combustion unit and being arranged for receiving and for cleaning the exhaust gas from the combustion unit to a cleaned exhaust gas, a cleaned gas exhaust pipe being in flow connection with the exhaust gas cleaning system and arranged for receiving the cleaned exhaust gas, a plume control system, comprising an air intake for taking in ambient air, a heater for heating the ambient air producing heated air, and a gas mixer placed in the cleaned gas exhaust pipe and arranged for mixing the cleaned exhaust gas in the cleaned gas exhaust pipe with the heated air resulting in an exhaust gas mixture that is blown out into the atmosphere via the one or more exhaust gas outlets. The application furthermore relates to a method for avoiding that exhaust gas that is created in a combustion unit in an engine room of a marine vessel and that is cleaned in an exhaust gas cleaning system that is in flow connection with an cleaned gas exhaust pipe which in its turn is in flow connection with one or more exhaust gas outlets, preferably arranged in a casing, and arranged for blowing out the exhaust gas into the atmosphere, descends and grounds on the marine vessel and/or other adjacent areas.

A connector system includes an adaptor with a magnetic target surface, and a nozzle that is configured to be connected to the magnetic target surface of the adaptor by a magnetic coupling. The nozzle has a housing having an inlet end and an outlet end, and a throughgoing channel having an axial extension therebetween. The housing includes one or more magnets that are arranged at the inlet end and configured to direct or indirect engage the magnetic target surface in a condition when the nozzle is connected to the adaptor. Further, the housing includes one or more air vents that are arranged at the outlet end and which have an axial extension being radially displaced in view of the axial extension of the throughgoing channel.

An apparatus and method of cooling an engine exhaust generated by an engine of a work machine having a hydraulically operated implement. The work machine includes an emission control system and a cooling system having an oil cooling system configured to cool an oil of a hydraulic system and an engine cooling system configured to cool an engine coolant circulating through the engine.
