Abstract:
The invention relates to an arrangement (1) for cooling exhaust gas, said arrangement comprising a housing (2) containing a heat transfer region (5), an actuator for regulating the flow of exhaust gas through the heat transfer region (5), and/or a bypass channel (6). Said housing (2) is embodied as a single component in the longitudinal direction of the inventive arrangement (1), and the actuator is arranged in the housing (2).
Abstract:
Exhaust after-treatment system for the reduction of particulate, NOX, HC, CO, VOCs, nano-particle count and sulfur dioxide from diesel exhaust. System employs diesel oxidation catalyst (10), exhaust cooling system (50,70,80), particulate converter (100), soot collection chamber (170), soot processing drum (200), EGR and water scrubber.
Abstract:
The invention relates to a method and device for purifying flue gas containing fine particles, in which method the flue gas is cooled to below the condensation point of water vapour and the fine particles in the flue gas are bound mainly to drops and/or to a liquid film.
Abstract:
The invention relates to a heat exchange device which comprises a first flow path for a first fluid and a second flow path for a second fluid. The components of the inventive heat exchanger are interconnected by material connections (10, 11). Those material connections (10, 11) whose material establishing the material fit is substantially directly exposed to the flow of the first fluid consist of a first connection material and those connections whose material establishing the material fit is not or not directly exposed to the flow of the first fluid consist of a second connection material. The composition of the first and the second connection material is different.
Abstract:
An exhaust purification system for use with diesel or other compression ignited systems to remove particulate and gaseous pollutants from the exhaust. The system includes a catalytic converter assembly that heats the exhaust to a level sufficient to incinerate particulate pollutants in the exhaust prior to the pollutants contacting the catalytic element and a plurality of gas cooling elements communicating with the exhaust outlet in the catalytic converter assembly for reducing the temperature of the exhaust passing from that assembly to about 100° F whereupon the cooled exhaust is directed back to the engine for further combustion.
Abstract:
An exhaust gas recirculation system (10) for an internal combustion engine (12), the internal combustion engine (12) having an intake manifold (26) and an exhaust manifold (24), comprising: a first valve having an inlet and an outlet, the inlet of said first valve (14) being connected to the exhaust manifold (24) of the internal combustion engine (12); a catalyst assembly (16) having an inlet and an outlet, the inlet of said catalyst assembly (16) being connected to the outlet of said first valve (14); a heat exchanger (18) having an inlet and an outlet, the inlet of said heat exchanger (18) being connected to the outlet of said catalyst assembly (16); a filter assembly (20) having an inlet and an outlet, the inlet of said filter assembly (20) being connected to the outlet of said heat exchanger (18), the outlet of said filter assembly (20) being connected to the intake manifold (26) of the internal combustion engine (12); and a valve control system (22) connected to said first valve (14) for opening and closing said first valve (14).
